Homes and businesses in Markham lose energy through gaps, cracks, and poorly insulated walls, attics, and crawl spaces. Spray foam insulation seals these gaps completely, creating an air-tight barrier that reduces energy loss and improves indoor comfort throughout the year. Foam Expert Group installs spray foam insulation for residential and commercial properties across Markham, ON.
Properties with outdated or insufficient insulation face higher energy bills, inconsistent indoor temperatures, and increased risk of moisture damage. We address these issues directly, working with homeowners and business owners who want a long-term solution rather than a temporary fix.
Our team brings technical expertise and local experience to every project, whether it’s a single-family home or a commercial building. We explain the details of our process below, including how spray foam performs in different areas of a property and what to expect when you work with us.
Spray foam insulation works in nearly every part of a home or commercial building, from the roofline down to the foundation. We apply it in open cavities, tight crawl spaces, and large commercial structures, adjusting the formula and technique to match each area.
Attics lose significant heat in winter and gain heat in summer, making them one of the most common areas we treat. We apply spray foam directly to the underside of the roof deck or along the attic floor, depending on your ventilation setup.
Rooflines benefit from foam because it seals gaps around rafters and blocks air leaks that traditional insulation misses. This helps maintain consistent indoor temperatures year-round.
Crawl spaces present different challenges, including moisture and ground-level drafts. We use closed-cell foam in these areas to create a moisture barrier while sealing off cold air infiltration.
Here’s a quick breakdown of common applications in these areas:
Basement walls often let in cold air and moisture, especially in older homes. We apply closed-cell spray foam directly to concrete or masonry walls to create an air and moisture barrier in one step.
Wall cavities in above-grade spaces also benefit from foam application during new construction or renovation projects. Once installed, the foam expands to fill gaps around wiring, plumbing, and framing that standard batt insulation cannot reach.
Rim joists are a frequent source of air leakage, since they sit at the junction between the foundation and the first floor. We target this area specifically because gaps here can account for a noticeable portion of a home’s total heat loss.
Sealing rim joists with spray foam typically takes less time than insulating an entire basement, but it makes a measurable difference in comfort.
Commercial properties in Markham and nearby areas have different insulation needs than residential homes, often involving larger surface areas and stricter energy codes. We work with warehouses, retail spaces, and office buildings to apply spray foam across roofs, walls, and metal building panels.
Metal buildings, in particular, benefit from spray foam because it controls condensation that forms on interior metal surfaces. This reduces the risk of rust and moisture damage over time.
Open commercial ceilings and exposed structural areas also receive spray foam to improve energy efficiency without requiring extensive framing changes. We coordinate installation schedules to minimize disruption to business operations, working around occupied hours when needed.
Spray foam insulation addresses two core priorities for property owners: consistent indoor temperatures and long-term protection against moisture-related damage. Below, we outline how it delivers on both fronts.
Spray foam expands on application, filling gaps, cracks, and voids that other insulation types often miss. This creates a continuous barrier against outside air infiltration.
Unlike batt insulation, which can leave small gaps around framing and fixtures, spray foam conforms to irregular surfaces. We apply it in attics, wall cavities, crawl spaces, and rim joists to seal areas where drafts commonly occur.
The result is fewer temperature fluctuations between rooms. Homeowners typically notice less reliance on space heaters or fans to compensate for uneven heating and cooling. In commercial buildings, this consistency helps maintain comfortable conditions across large open spaces or multi-room layouts.
A well-sealed building envelope reduces the workload on heating and cooling systems. When conditioned air stays inside instead of escaping through gaps, HVAC equipment cycles less frequently.
Closed-cell spray foam also acts as a moisture barrier. It resists water absorption, which lowers the risk of mold growth and wood rot in walls, attics, and crawl spaces.
Here’s a quick comparison of common insulation concerns spray foam addresses:
Concern | How Spray Foam Helps |
Air leaks | Seals gaps and cracks on contact |
Moisture intrusion | Closed-cell formulas resist water absorption |
Uneven temperatures | Creates consistent thermal barrier |
Pest entry points | Fills small openings pests use to enter |
We recommend closed-cell foam for areas prone to moisture, such as basements or roof decks, based on the specific conditions of your property.
Gaps in insulation don’t just sit there quietly. They actively work against your home or building, letting conditioned air escape and forcing your HVAC system to compensate around the clock.
Uninsulated gaps create direct paths for outdoor air to move indoors. We often find these gaps around attic hatches, wall penetrations, and rim joists where conventional insulation has settled or was never installed correctly.
The result is uneven temperatures from room to room. One space feels comfortable while another, often above a garage or near an exterior wall, stays noticeably colder in winter or warmer in summer.
Common signs include:
We address these gaps directly with spray foam, since it expands to fill irregular spaces that batt or blown-in insulation can miss.
When air escapes through insulation gaps, your furnace and air conditioner run longer to maintain the set temperature. This added workload shows up on monthly utility bills and shortens the lifespan of HVAC equipment.
We see this most often in older homes and commercial buildings where insulation has degraded or was installed to outdated standards. The system isn’t broken, it’s simply working harder than it should to offset heat loss or heat gain through poorly sealed areas.
Over a heating or cooling season, this translates into measurable added cost. Sealing these gaps with spray foam reduces the demand placed on your equipment and stabilizes indoor temperatures without requiring constant thermostat adjustments.
We base our recommendations on building science and clear communication, not guesswork. Homeowners and business owners in Markham get a straightforward process with no surprises along the way.
Every property has different insulation needs based on its age, construction type, and current performance issues. We evaluate factors like existing insulation levels, moisture patterns, air leakage points, and the building’s structural layout before recommending a solution.
A century home in Markham requires a different approach than a new commercial build. We account for these differences rather than applying a one-size-fits-all method.
Our recommendations include:
This approach means you get a solution built for your property, not a generic package.
We provide a written scope of work before any project begins. This document outlines the areas to be treated, the type of foam used, estimated thickness, and total project cost.
We answer questions directly and explain our reasoning when asked. If a change comes up during the project, we communicate it before proceeding, not after the fact.
Our team also explains what to expect during and after installation, including curing times and any temporary access restrictions. You know what is happening at each stage, from the initial assessment to the final walkthrough.
Every project moves through a clear sequence of stages, from the first site visit to the final walkthrough. Here’s what you can expect at each point along the way.
We start with an on-site inspection of the space to be insulated.
Our technicians check existing insulation conditions, identify air leaks, and note any areas of thermal bridging. We measure square footage and calculate the amount of material needed for the job.
We also assess accessibility and flag any safety considerations, such as electrical wiring or plumbing near the work area. Once we’ve gathered this information, we put together an installation plan specific to your property.
This plan outlines the type of foam we’ll use, the estimated timeline, and any prep work required before spraying begins. We review this plan with you before scheduling the installation date.
Before application, we prepare the space by covering surfaces that don’t need insulation and setting up proper ventilation.
Our team wears protective equipment, and we may ask you to vacate the area during this stage. We then apply the spray foam using professional-grade equipment, working section by section to maintain consistent coverage.
The foam expands and cures as it’s applied, filling gaps and sealing the surface. Once the application is complete, we conduct a final review.
This includes checking for even coverage, confirming there are no missed spots, and inspecting for any surface irregularities. We clean up the work area and remove protective coverings before we consider the job finished.
Installation time depends on the size of the project and the type of foam being used.
A single room or small attic space typically takes a few hours to complete. Larger residential jobs, such as whole-house insulation, can take one to two days.
Commercial projects vary more widely, since square footage and building layout affect the timeline. We’ll give you a specific estimate during the site review stage, based on the scope of your project.
Project Size | Estimated Time |
Small attic or single room | 2-4 hours |
Whole-house residential | 1-2 days |
Commercial building | Varies by square footage |
Spray foam cures quickly, but the space still needs time to ventilate before it’s safe to occupy.
Most areas are ready for re-entry within 24 hours of application. We recommend keeping the space well-ventilated during this period to allow any remaining odors to dissipate.
For commercial buildings, we’ll advise on a specific timeline based on the size of the area treated and the ventilation systems in place. We don’t consider a job complete until the space is safe and ready for normal use.
We install spray foam insulation throughout Markham and the neighboring communities of York Region. Our service area covers residential and commercial properties, and our pricing reflects the size and scope of each project.
We work with property owners across Markham, Unionville, Thornhill, Richmond Hill, Stouffville, and Vaughan. Our crews are familiar with the housing styles common to this region, from older Markham homes to new subdivisions.
We also serve commercial clients, including warehouses, retail spaces, and office buildings. Our team adjusts scheduling to fit business hours and minimize disruption to daily operations.
Every job starts with an on-site assessment specific to your property. We do not apply a one-size-fits-all approach, since insulation needs vary by building age, layout, and construction material.
Spray foam insulation pricing depends on several factors:
Closed-cell foam costs more than open-cell foam due to its higher density and greater R-value per inch. Most residential projects in Markham range from a few hundred dollars for small areas to several thousand dollars for whole-home applications.

Pricing, application areas, material types, and installation timelines are common questions we hear from homeowners and business owners in Markham. Below, we answer the questions that come up most often during consultations.
Costs depend on the square footage, the type of foam used, and the complexity of the space being insulated. Attics, walls, and crawl spaces each require different amounts of material and labor. We provide a detailed quote after assessing your property, so you know exactly what to expect before work begins.
We install spray foam in attics, basements, crawl spaces, exterior walls, and rim joists. It also works well in commercial buildings, including warehouses, offices, and industrial facilities. Each area has specific requirements, and we adjust our application method accordingly.
Open-cell foam is lighter and more flexible, making it a good fit for interior walls and sound dampening. Closed-cell foam is denser and offers a higher R-value per inch, along with added moisture resistance. We help you choose the right option based on your building’s structure and climate exposure.
Yes, once fully cured, spray foam is safe for occupied spaces. During installation, proper ventilation and safety protocols are followed to manage temporary fumes. Our technicians are trained to handle application safely and efficiently.
Most residential projects take one to two days, depending on the size of the area and the type of foam applied. Commercial installations may take longer due to scale and site logistics. We provide a timeline estimate during your initial consultation.
Spray foam creates an air seal that reduces heat loss in winter and heat gain in summer. This lowers the workload on heating and cooling systems, which can reduce monthly energy costs over time. Actual savings vary based on your home’s size, current insulation levels, and energy usage patterns.
