TOP INSULATION CONTRACTORS IN GREATER KINGSTON, ONTARIO

Choosing an insulation contractor can be challenging, particularly when different areas of a home may require different materials and installation methods. An under-insulated attic, a damp crawl space, an exposed basement wall, and a drafty addition are not necessarily solved in the same way. The right contractor should be able to assess the building, explain the available options, and recommend an approach suited to the home rather than promoting one product for every situation.

This guide reviews six insulation companies serving Greater Kingston, including Kingston, Amherstview, Glenburnie, Bath, Napanee, South Frontenac, and surrounding communities. The companies offer services such as spray foam insulation, blown-in cellulose, batt and mineral-wool installation, attic upgrades, insulation removal, air sealing, vapour barriers, and insulation for basements and crawl spaces. Some focus primarily on residential energy-efficiency improvements, while others also work on new construction and commercial projects.

The purpose of this article is to help Kingston-area homeowners understand each company’s background and principal service specialties. It is an editorial overview rather than a guarantee that one contractor will be the right choice for every property. Availability, project scope, installer qualifications, warranties, and pricing should all be confirmed directly before work begins.

Kingston Insulation is an independent information website operated by Joe Ramsay and Associates Inc. It does not perform insulation work directly. When a visitor requests an assessment through this website, the inquiry is referred to an independent local service provider. The first company reviewed below, Global Insulation Solutions of Napanee, is Kingston Insulation’s preferred recommendation for homeowners seeking an insulation assessment in the Greater Kingston area.

1. GLOBAL INSULATING SOLUTIONS LTD — KINGSTON INSULATION'S PREFERRED RECOMMENDATION

Global Insulating Solutions Ltd. is a full-service insulation contractor based in Napanee, Ontario. The company serves homeowners, builders, and commercial property owners in Greater Kingston and other Eastern Ontario communities. Its location makes it well positioned for projects in Kingston, Amherstview, Odessa, Bath, Napanee, and surrounding rural areas.

Global Insulating Solutions is the preferred number-one recommendation from the Kingston Insulation website. This recommendation reflects the company’s range of services, local availability, and ability to assess different parts of a building rather than relying on one insulation material for every project. Kingston Insulation is an independent information website and does not perform insulation work itself. Assessments and installation services are completed by Global Insulating Solutions as a separate local contractor.

The company reports more than 30 years of industry experience and works on both residential and commercial properties. Its principal services include spray foam insulation, blown-in insulation, and conventional batt-and-poly systems. Offering several installation methods can be valuable because the correct choice depends on where insulation is being installed, how the building was constructed, and whether air leakage or moisture movement is contributing to the problem.

Spray foam insulation is one of the company’s main specialties. It can be useful in areas where insulation and air sealing need to be addressed together, including rim joists, crawl spaces, basement walls, additions, garages, and irregular framing cavities. Closed-cell spray foam may also be considered where space is limited or where additional resistance to moisture movement is needed. Any proposed application should be evaluated in relation to ventilation, drainage, fire-protection requirements, and the rest of the building assembly.

Global Insulating Solutions also installs blown-in insulation, which is commonly used to increase the thermal resistance of accessible attics. Blown-in material can cover uneven surfaces and reach around framing more continuously than pre-cut batts when it is installed correctly. Before adding insulation, the attic should be examined for air leakage, moisture staining, blocked ventilation, unsafe electrical conditions, or other defects that may need attention first.

For open walls and new construction, the company’s batt-and-poly services provide another practical option. Batt insulation is fitted between framing members, while polyethylene may form part of the air-and-vapour-control system. The effectiveness of this assembly depends heavily on careful installation around wiring, plumbing, corners, windows, and other interruptions. Small gaps or poorly sealed penetrations can reduce the performance of an otherwise suitable product.

This range allows Global Insulating Solutions to consider different approaches for attics, walls, basements, crawl spaces, garages, renovations, and new buildings. That flexibility is particularly relevant around Kingston, where heritage masonry houses, postwar homes, rural properties, and modern subdivisions can present very different insulation challenges. Homeowners can request an assessment to discuss the problem, review the conditions in the home, and determine which material or combination of materials may be appropriate before deciding whether to proceed.

2. BDK FOAM INSULATION INC.

BDK Foam Insulation Inc. is a family-run insulation company located at 491 O’Connor Drive in Kingston. Founded in 2007, the company works on residential and commercial projects in Kingston and across a broader Eastern Ontario service area. BDK reports more than 25 years of combined industry experience among its team and is listed as an insulation contractor by the Kingston Construction Association.

Spray foam insulation is one of BDK’s principal specialties. Because spray foam expands after application, it can insulate and seal gaps around framing, penetrations, and irregular building components. This can make it useful for basement walls, crawl spaces, rim joists, garage ceilings, additions, roof assemblies, and other locations where conventional insulation may be difficult to fit continuously. Spray foam must still be selected and installed as part of a properly planned building assembly, particularly where moisture control and ventilation are concerns.

BDK also offers blown-in attic insulation. This type of upgrade may be appropriate when an attic has an insufficient or uneven layer of existing insulation. Loose material can be distributed across the attic floor to improve coverage around framing and other obstructions. However, adding insulation should normally follow an inspection for air leakage, bathroom exhaust problems, moisture damage, blocked soffit ventilation, and unsafe fixtures. Increasing insulation depth without correcting an underlying defect may conceal the problem rather than resolve it.

Batt insulation is another part of the company’s service range. Fibreglass or mineral-wool batts are commonly installed in open wall cavities, ceilings, floors, and other accessible framed areas. They can provide a cost-effective solution during renovations or new construction, but their performance depends on precise fitting. Gaps, compression, and poorly cut sections around pipes or electrical boxes can reduce the effective thermal resistance of the completed assembly.

One specialty that distinguishes BDK from some residential insulation companies is the application of thermal barriers and fire-resistant coatings. Certain exposed foam-plastic insulation applications require an approved protective covering under the Ontario Building Code. A homeowner considering spray foam in an exposed basement, workshop, utility area, or other accessible space should ask what protective treatment is required and whether it is included in the quotation.

BDK may be worth considering for homeowners who want one contractor to discuss spray foam, blown-in attic insulation, batt installation, and the protective coatings associated with exposed foam. Its local office, identifiable staff, Kingston Construction Association listing, and portfolio of residential and commercial projects provide useful indications of an established operating business. As with any contractor, homeowners should confirm installer qualifications, insurance, the specific products proposed, and the warranty terms for their project.

3. REITZEL BROS. INSULATION INC.

Reitzel Bros. Insulation Inc. has served Kingston and surrounding communities since 1991. The company works with residential, commercial, and agricultural properties and is particularly associated with cellulose-fibre insulation. It is also listed by the Kingston Home Builders Association and maintains an A+ rating with BBB, providing homeowners with independent sources through which to review its business history.

Cellulose insulation is the company’s central specialty. Commonly manufactured using a high proportion of recycled paper fibre treated for fire and pest resistance, cellulose can be installed in several ways. Reitzel Bros. offers loose-fill attic insulation, dense-packed material for enclosed wall cavities, and spray-applied cellulose for open walls during construction or renovation. These methods allow the company to address both existing buildings and newly framed spaces.

Blown-in cellulose is frequently used to improve attic insulation. Its loose texture helps it cover irregular areas and fill around framing more continuously than poorly fitted batts. Before installation, homeowners should confirm whether the proposed work includes air sealing, protection around heat-producing fixtures, attic-hatch improvements, ventilation baffles, and an examination of moisture conditions. The depth and settled R-value of the finished insulation should also be documented in the quotation.

The company’s drill-and-fill service may be of particular interest for older Kingston homes with under-insulated exterior walls. Small access holes can be created so cellulose is blown into enclosed wall cavities without removing all of the interior plaster or drywall. This approach may reduce disruption, although its suitability depends on the wall construction, existing insulation, exterior cladding, wiring, moisture conditions, and the presence of hidden obstructions. Kingston’s limestone buildings and other solid-masonry houses require a different assessment because they may not contain conventional framed cavities.

Reitzel Bros. also promotes cellulose for acoustic applications in interior walls, ceilings, offices, and multi-unit buildings. Dense fibre can help reduce sound transmission, although results depend on the complete wall or floor assembly rather than insulation alone. Other services include basement and crawl-space insulation, fibreglass batt-and-vapour-barrier packages for new homes, and the replacement of old or damaged insulation.

Homeowners should note an important limitation regarding contaminated material. Reitzel Bros. advises that insulation suspected of containing asbestos, contaminated vermiculite, mould, or hazardous animal waste should be tested before removal. The company states that it does not test or remove hazardous insulation itself, although it may coordinate with an appropriate specialist and install replacement cellulose afterward.

Reitzel Bros. is therefore a notable option for homeowners specifically interested in cellulose, enclosed-wall retrofits, attic improvements, or acoustic insulation. Its long operating history and specialized approach may be especially relevant to older houses where minimizing demolition is a priority.

4. KINGSTON SPRAY FOAM INSULATION

Kingston Spray Foam Insulation is a locally based contractor operating from 1472 McAdoo’s Lane in Glenburnie. The company serves homeowners, builders, and commercial clients throughout Kingston and surrounding Eastern Ontario communities, including Napanee, Gananoque, Belleville, Brockville, Picton, and Westport. It is listed by the Kingston Home Builders Association, which identifies the company as using licensed Canadian Urethane Foam Contractors Association installers.

Despite its name, Kingston Spray Foam Insulation offers more than spray foam. Its services include closed-cell spray foam, batt and Rockwool insulation, blown-in cellulose, vapour-barrier installation, attic remediation, and fire-resistant coatings. This broader selection allows different materials to be considered for different portions of a building.

Closed-cell spray foam is one of the company’s primary specialties. It can provide insulation, air control, and resistance to moisture movement in a relatively thin application. Typical uses include foundation walls, crawl spaces, exterior walls, roof assemblies, under-slab applications, trailers, workshops, metal buildings, and irregular framing. Spray foam can be effective in the right location, but it should not be treated as an automatic solution for every draft or moisture complaint. The substrate condition, drainage, ventilation, indoor humidity, and required fire protection should be evaluated before installation.

For conventional framed walls, ceilings, and floors, the company installs batt and Rockwool products. Mineral-wool insulation is valued for its fire resistance, sound absorption, and ability to retain its shape, while fibreglass batts remain a widely used and economical option. Both depend on careful fitting around services and framing. Homeowners comparing quotations should ask whether air sealing and vapour-control details are included or priced separately.

Blown-in cellulose is available for attics and other accessible spaces where continuous loose-fill coverage is beneficial. The company also offers attic remediation, which may involve removing deteriorated insulation, investigating moisture or ventilation problems, and upgrading the attic assembly. This is relevant in Kingston’s cold winters, when warm indoor air leaking into an attic can contribute to condensation, frost accumulation, and uneven roof temperatures.

Fire-resistant coatings are another relevant service. Foam plastic left exposed in certain locations may require an approved thermal or ignition barrier. The applicable product and level of protection depend on the space and building-code requirements, so the scope should be clearly identified in the contract.

Kingston Spray Foam Insulation may suit homeowners seeking a contractor experienced in spray foam but also able to discuss cellulose, fibreglass, mineral wool, and attic remediation. Its physical location, KHBA membership, local telephone number, named contact information, and documented service area support its status as an established local operating company rather than a referral website.

5. KINGSTON'S INSULATING SOLUTIONS

Kingston’s Insulating Solutions is a locally owned insulation business serving Kingston and surrounding Eastern Ontario communities. BBB records identify Manny Oliveira as the owner and show that the organization has maintained a business profile since 2013. Although the company is not BBB accredited, it currently holds an A+ BBB rating. Accreditation and rating are separate designations, so homeowners should avoid interpreting one as the other.

The company works on residential, commercial, and municipal projects. Its services cover attics, basements, crawl spaces, garage ceilings, headers, exterior walls, exposed floors, underslab areas, and other parts of the building envelope. The principal installation categories are closed-cell spray foam, blown-in cellulose, and traditional batt-and-poly insulation.

Closed-cell spray foam can be useful where both thermal insulation and air sealing are required. It is commonly considered for rim joists, foundation walls, crawl spaces, exposed floors, garages, renovations, and complicated framing. Because the foam adheres to the substrate and expands into small gaps, it can create more continuous coverage than a poorly fitted batt system. The installation still requires appropriate surface preparation, thickness control, ventilation during application, and any fire-protective covering required for the finished space.

For attics and enclosed areas, Kingston’s Insulating Solutions offers loose-fill cellulose. This material can improve coverage across irregular attic floors and may also provide useful acoustic performance. A complete attic upgrade should consider more than the nominal R-value. Air leakage from the living space, bathroom exhaust ducts, attic access hatches, soffit ventilation, roof leaks, and evidence of condensation can all affect the result.

Batt-and-poly systems may be used in open framing during renovations and new construction. In this type of assembly, the insulation slows heat flow while the polyethylene layer may form part of the air-and-vapour-control system. Installation quality is critical because discontinuities around windows, electrical penetrations, plumbing, and framing transitions can permit heat and moisture to bypass the insulation.

The company’s broad service list may be helpful for projects that involve several building areas or require a combination of materials. A homeowner renovating a basement, for example, might compare spray foam at the rim joists with batt insulation in framed walls rather than assuming that one material must be used throughout. Similarly, an attic may benefit from targeted air sealing followed by blown-in cellulose.

Kingston’s Insulating Solutions is a legitimate local contractor with identifiable ownership, a longstanding BBB file, a local 613 phone number, and consistent information across independent business directories. Homeowners considering the company should still request a detailed written scope identifying the product, installed thickness, intended R-value, preparatory work, fire protection, cleanup, warranty, and responsibility for correcting any pre-existing moisture or ventilation defects.

6. ECO-SOLUTIONS

Eco-Solutions is a locally owned insulation contractor based at 8769 Loyalist Parkway in Bath, west of Kingston. The company serves Bath, Kingston, Loyalist Township, and other nearby Eastern Ontario communities. Independent listings from the Kingston Construction Association and BBB identify the same local address, telephone number, and company contact, supporting its status as an operating insulation business rather than a lead-generation website.

The company was incorporated in 2013 and is listed as a BBB-accredited business with an A+ rating. BBB identifies its service categories as spray foam insulation, blown insulation, insulation removal, fireproofing, attic upgrades, and related energy-efficiency improvements. Eco-Solutions also states that it is insured and uses certified installers.

Spray foam insulation is a core part of the company’s work. Polyurethane foam can reduce heat flow while sealing many of the small openings that permit uncontrolled air movement. Possible applications include walls, basements, crawl spaces, attics, garage ceilings, and other irregular or difficult-to-access areas. The suitability of spray foam depends on the building assembly, however. Applying foam without understanding the source of moisture, the condition of the substrate, or the ventilation strategy can create avoidable complications.

Eco-Solutions also installs blown fibreglass and cellulose insulation, particularly for attic upgrades. Adding loose-fill material may be one of the more straightforward ways to improve an attic with inadequate insulation, but the existing conditions should be checked first. Signs of roof leakage, condensation, animal activity, damaged wiring, obstructed soffits, or exhaust fans terminating in the attic may require corrective work before new insulation is added.

Air sealing is closely related to attic performance. During winter, warm interior air can escape through ceiling penetrations and carry moisture into the colder attic. Sealing accessible gaps around wiring, plumbing, partition walls, and the attic hatch can improve the effectiveness of the insulation installed above them. Homeowners should ask whether air sealing is included in the quoted attic upgrade and which areas can realistically be reached.

The company’s fireproofing services may also be relevant when spray foam will remain exposed. Depending on the location and use of the space, the Ontario Building Code may require a thermal barrier or another approved protective coating. The quotation should specify the proposed product and explain where it will be applied.

Eco-Solutions may be a practical candidate for homeowners west of Kingston who are comparing spray foam, blown-in attic insulation, air sealing, or fire-protection work. Its Bath location is convenient for projects in Loyalist Township and Napanee while remaining within the Greater Kingston market. Before hiring, homeowners should verify current insurance, installer credentials, material specifications, warranties, and whether the assessment covers ventilation and moisture conditions as well as insulation depth.

WHAT TO CONSIDER WHEN CHOOSING AN INSULATION CONTRACTOR

The right insulation contractor should begin by identifying the cause of the problem rather than simply recommending more material. Drafts, cold floors, uneven room temperatures, attic frost, condensation, and high energy use can result from several interacting conditions. Insulation may be part of the solution, but air leakage, ventilation, moisture entry, roof defects, or poorly connected heating ducts may also need attention.

Ask each contractor to inspect the relevant parts of the home and explain what was observed. A useful assessment should identify where the thermal and air-control boundaries are located, whether the existing insulation is damaged or incomplete, and what preparatory work is required. Be cautious when a recommendation is made without examining the attic, basement, crawl space, or other area involved.

Obtain a written quotation that describes the work in detail. It should identify the insulation product, manufacturer, application area, installed thickness, target R-value, air-sealing work, vapour-control measures, ventilation modifications, required fire protection, cleanup, and warranty. If old insulation must be removed, the quotation should explain whether testing or specialized hazardous-material handling could be required.

Credentials are especially important when spray polyurethane foam is proposed. Homeowners should ask whether the installer is trained and certified for the specific foam system being used. The contractor should also carry appropriate liability insurance and workplace coverage. Copies of current documentation can be requested before work begins rather than after a problem occurs.

Homeowners should compare the proposed building strategy, not just the total price. A lower quotation may exclude air sealing, ventilation baffles, attic-hatch insulation, protective coatings, disposal, or other work included by another company. Conversely, the most expensive proposal is not automatically the best. The strongest quotation is usually the one that clearly connects the recommended work to the conditions found in the home.

References and reviews can provide additional context, but they should be read carefully. Look for comments describing projects similar to the one being considered and pay attention to communication, site protection, cleanup, schedule management, and how concerns were handled. Membership in a local construction association or a longstanding independent business profile can be another useful signal, although no single badge or rating guarantees the quality of a future installation.

It is also worth asking how the project could affect moisture movement and ventilation. Adding insulation changes the way heat moves through a building, while air sealing changes how indoor moisture escapes. In an attic, for example, adding insulation without sealing ceiling penetrations may leave the main source of heat and moisture leakage unresolved. In a basement or crawl space, insulation should be planned alongside drainage, humidity control, and the condition of the foundation.

Older Kingston homes may require additional care. Heritage masonry, knob-and-tube wiring, vermiculite, inaccessible wall cavities, shallow roof assemblies, and previous renovations can complicate otherwise routine work. Materials suspected of containing asbestos should be tested by an appropriate professional before they are disturbed. An insulation contractor should be willing to identify the limit of its own expertise and recommend another qualified specialist when necessary.

Finally, avoid making a decision under unnecessary pressure. A reputable contractor should allow time to review the scope, ask questions, compare alternatives, and understand the warranty. Insulation can remain hidden for decades, so careful assessment and installation matter more than a rushed decision or an appealing headline price.

A PRACTICAL NEXT STEP FOR KINGSTON HOMEOWNERS

Comparing insulation contractors is an important part of planning a home improvement, but the process should begin with a clear understanding of the property. The most appropriate solution will depend on the home’s age, construction, existing insulation, ventilation, moisture conditions, and the specific comfort problem being investigated.

Homeowners who would like professional input can request a free insulation assessment by completing the form or calling the phone number provided on the Kingston Insulation website. There is no obligation to proceed with installation after the assessment.

Kingston Insulation is an independent information website operated by Joe Ramsay and Associates Inc. It is not an insulation contractor and does not perform the assessment or installation work. Requests submitted through this website are referred to Global Insulating Solutions Ltd., the preferred local provider featured in this guide.

A representative from Global Insulating Solutions will follow up to discuss the property and the concerns being experienced. If a site visit is appropriate, the company can examine the relevant areas, explain its observations, and outline possible solutions. Homeowners can then review the recommendations, ask questions, and decide at their own pace whether any proposed work is right for their property.
