Air Sealing

Even the best insulation won’t perform at its peak if your home isn’t properly sealed. Tiny cracks, gaps, and leaks around windows, doors, ducts, and foundations allow conditioned air to escape, causing higher energy bills and uncomfortable drafts.

This not only improves the performance of your insulation but also reduces moisture infiltration, prevents cold spots, and helps control allergens and dust. By combining air sealing and spray foam insulation, we provide complete protection that keeps your home comfortable, efficient, and healthier to live in.



What Types of Material Do We Use For Residential and Commercial Spaces?

Spray Foam Insulation

It is a superior-performance material that expands on contact to seal gaps, cracks, and voids, creating an airtight and moisture-resistant barrier. It provides superior thermal performance compared to traditional insulation, helping reduce energy loss, prevent drafts, and improve indoor comfort. The result is lower heating and cooling costs, better air quality, and a more durable, energy-efficient space.

Fiberglass Blown-In Insulation

It is a loose-fill material made of tiny glass fibers that’s blown into attics or wall cavities to create a uniform layer of thermal protection. It effectively reduces heat loss, improves energy efficiency, and helps maintain consistent indoor temperatures. This type of insulation is quick to install, affordable, and ideal for upgrading existing homes without major renovations.

Cellulose Blown-In Insulation

It is an eco-friendly, loose-fill material made from recycled paper treated for fire and pest resistance. It’s densely packed into attics or wall cavities to minimize air leaks and improve energy efficiency. The result is excellent thermal performance, reduced noise, and lower heating and cooling costs throughout the year.

Rigid Foam Board Insulation

It is a durable foam panel made from materials like polystyrene or polyisocyanurate, designed to provide high thermal resistance in walls, roofs, and foundations. It offers excellent moisture control and prevents heat loss. This insulation type is ideal for basements, crawl spaces, and exterior walls where long-lasting, high-performance insulation is needed.

Mineral Wool Insulation

It is made from natural rock or recycled slag, offering excellent thermal, soundproofing, and fire-resistant properties. It’s moisture-resistant and maintains its shape over time, preventing gaps or settling. Ideal for walls, attics, and basements, mineral wool helps improve energy efficiency, indoor comfort, and overall home safety.

FAQ's

We understand that upgrading your home or business with insulation is a major decision. Below are the most common questions we receive from homeowners and commercial property owners about spray foam insulation.

  • What is spray foam insulation and how does it work?

    Spray foam insulation is a premium insulation material that expands when applied, filling gaps, cracks, and hard-to-reach areas. It creates an airtight seal that prevents heat loss in the winter and keeps cool air inside during the summer. Unlike fiberglass or cellulose, spray foam provides both insulation and air sealing in one step, making it one of the most efficient insulation options for homes and commercial properties in Newmarket.

  • Why should I choose spray foam insulation for my home or business?

    Spray foam insulation offers superior energy efficiency, air quality improvement, and comfort. Homeowners and business owners who choose spray foam typically save 30–50% on energy bills each year. It also helps reduce drafts, noise, and moisture problems—common issues in older Newmarket homes. It’s an investment that adds long-term value and comfort to your property.

  • How long does spray foam insulation last?

    When installed by professional insulation contractors, spray foam insulation can last over 50 years. It doesn’t sag, settle, or deteriorate like traditional insulation materials. That means you’ll enjoy consistent performance, lower energy costs, and a comfortable environment for decades without needing replacement.

  • Is spray foam insulation safe for my family or employees?

    Absolutely. Once it cures, spray foam insulation is completely safe. Our products are low-VOC and environmentally friendly, ensuring your home or business remains healthy and odor-free. Many of our Newmarket clients appreciate that spray foam helps improve indoor air quality by sealing out dust, pollen, and pollutants.

  • How much does spray foam insulation cost in Newmarket, Ontario?

    The cost of spray foam insulation depends on factors such as square footage, thickness, and type of foam (open-cell or closed-cell). On average, homeowners in Newmarket can expect prices between $3 to $6 per square foot, depending on the project’s complexity. While the upfront cost is higher than fiberglass, spray foam quickly pays for itself through energy savings and reduced maintenance.

  • Can I qualify for government rebates or incentives?

    Yes! Many homeowners and business owners in Ontario qualify for energy efficiency rebates and insulation upgrade incentives. Our team helps clients navigate these programs to maximize savings. Whether it’s through Enbridge Home Efficiency Rebates or other provincial initiatives, we’ll guide you through every step to make your insulation upgrade more affordable.

  • What’s the difference between spray foam and blown-in insulation?

    Spray foam insulation creates an airtight seal and offers the highest R-value per inch, while blown-in insulation (typically cellulose or fiberglass) is a more affordable option that’s great for attics and open spaces. We’ll assess your property and recommend the best solution for your specific needs, budget, and goals.

  • Do you offer insulation for basements, garages, and crawl spaces too?

    Yes. In addition to attics and walls, we offer comprehensive insulation services including basement insulation, garage insulation, and crawl space insulation. These areas are often overlooked, yet they’re major sources of energy loss. Properly insulating these spaces helps improve your home’s comfort and overall energy efficiency.

Why You Need Insulation and Understanding R-Value

Your home or commercial space requires the appropriate level of insulation to effectively block both heat and cold, creating a comfortable and energy-efficient environment throughout the year. A well-insulated space not only helps maintain a stable indoor temperature but also plays a critical role in ensuring proper moisture regulation. This is essential for preventing issues such as mold growth and structural damage, ultimately contributing to the long-term health and durability of your property.


Let’s discuss R-values. For those unfamiliar with insulation, R-value indicates how effectively a material resists heat transfer. A higher number signifies superior insulation performance. Additionally, the building code regulations for spray foam in Ontario establish specific R-value standards depending on the location and intended use.


Here’s what the code requires:


  • Exterior walls: Minimum of R-22
  • Attics: R-60 is standard
  • Basement walls: R-12 to R-20, based on whether it’s situated above or below grade.
  • Crawl spaces: Should be a minimum of R-20 for exterior walls or floors.


Now, here’s the twist: not all spray foams are made the same. Open-cell foam boasts a lower R-value (approximately R-3.5 to R-4 per inch), whereas closed-cell foam offers an R-value ranging from R-6 to R-6.5 per inch. This is why many professionals in Ontario prefer closed-cell spray foam; it complies with codes more swiftly and requires less thickness.


Pro Tip:

  • To attain an R-22 rating with open-cell foam, you would need to install over six inches, which may not accommodate standard wall studs
  • With closed-cell foam, only approximately 3.5 inches is required to achieve R-22
  • By selecting the right type of spray foam, you can save money and space — and keep from running afoul of the rules.
