Residential Attic Spray Foam Insulation in Newmarket, Ontario
Newmarket Spray Foam Insulation has spent over 25 years perfecting attic insulation for homes across Newmarket, York Region, and surrounding Ontario communities. Our experience isn’t just time in business — it’s the depth of skill our master technicians bring to every job. Unlike fly-by-night contractors who cut corners with rushed installs or off-the-shelf approaches, our crew uses proven diagnostic tools (thermal imaging, blower-door testing) and industry-leading techniques to diagnose problems, specify the right materials, and execute installations precisely. We train continuously, follow best practices for air sealing and ventilation, and deliver results that consistently outperform typical insulation upgrades.
Our attic work covers new construction, full retrofits, and storm or leak repairs — plus targeted upgrades like attic hatch sealing, baffle installation, and insulation top-ups. For retrofits we carefully remove degraded or contaminated insulation, address hidden moisture or pest issues, then install premium materials that match the application: high-density blown cellulose or fiberglass for even coverage, and open- or closed-cell spray foam where advanced air-sealing and higher thermal performance are required. We only spec CAN/ULC-approved, low-emission products chosen for long-term performance in Ontario’s cold winters and humid summers, because premium materials deliver the best energy savings, indoor air quality, and longevity.
What truly distinguishes our attic service is meticulous attention to detail from start to finish. Before work begins we perform a comprehensive inspection and provide a written plan that shows target R-values, air-sealing strategies, and ventilation fixes; during the job we communicate schedules, protection measures, and progress updates; and after completion we verify results with post-installation checks — including infrared imaging and a walkthrough with you. We document our work with photos and a clear report so you can see the difference, and we don’t consider a job done until the attic performs as promised. That level of transparency and follow-through is why homeowners recommend us over competitors.
We treat root causes, not just symptoms — sealing air leaks, correcting ventilation imbalances, and addressing moisture pathways so your new attic insulation performs for decades rather than masking recurring problems. Most typical attic upgrades are completed in one day (larger or more complex retrofits may take 1–2 days), and we always factor prep, air sealing, and verification into the schedule so there are no surprises. When you choose Newmarket Spray Foam Insulation, you’re investing in a durable, code-compliant solution that improves comfort, lowers energy bills, and protects your home’s structure for the long term.

Our Complete Attic Insulation Service
Attic Inspections & Assessments
We begin with a thorough and detailed inspection to meticulously measure the insulation depth throughout the various areas of the property. This process includes detecting any air leaks that may compromise energy efficiency, checking for the presence of moisture or mold that could harm the structural integrity and health of the environment, and evaluating the overall ventilation performance to ensure optimal airflow. Each of these factors plays a crucial role in determining the effectiveness of the insulation and the overall comfort of the living space.
Insulation Removal & Replacement
Aged or damaged insulation is carefully removed to ensure that any compromised material is entirely taken out, allowing for a clean slate. This is then replaced with contemporary, high-efficiency insulation materials that are designed to provide superior thermal performance and energy savings. The use of advanced insulation solutions not only enhances the overall comfort of the space but also contributes to energy conservation by reducing heating and cooling costs over time.
Spray Foam Insulation
When considering attic insulation, spray foam insulation emerges as the optimal choice for achieving maximum energy efficiency and enduring comfort. This advanced solution effectively establishes a continuous air and moisture barrier, thereby eliminating drafts, preventing water intrusion, and ensuring consistent indoor temperatures throughout the year. With its exceptional R-value and airtight seal, spray foam insulation stands out as a high-performance option for attics, enabling homeowners to substantially reduce energy costs while enhancing the overall quality of their living environment.
Blown-In Insulation Installation
An economical solution to enhance R-value and ensure uniform coverage in every nook and cranny of your attic is essential for maintaining optimal energy efficiency in your home. By addressing insulation needs comprehensively, this approach not only improves thermal performance but also helps create a more comfortable living environment throughout the year. Ensuring that every corner of your attic is properly insulated can significantly reduce heating and cooling costs, making it a smart investment for homeowners looking to maximize both comfort and savings.
Air Sealing
Before insulating, we carefully seal cracks, gaps, and openings around light fixtures, vents, and attic hatches to effectively eliminate drafts. This crucial step ensures that our insulation works efficiently, preventing cold air from seeping in and warm air from escaping, ultimately contributing to a more comfortable and energy-efficient environment in your home. By addressing these areas, we help maximize the performance of your insulation and enhance the overall energy efficiency of your living space.
Attic Ventilation Upgrades
Proper airflow is critical for maintaining the integrity of your roofing system. To ensure optimal ventilation, we install essential components such as baffles, soffit vents, and ridge vents. These elements work together efficiently to prevent moisture buildup, which can lead to mold and mildew, ultimately compromising the structural integrity of your roof. By facilitating effective airflow, we not only enhance comfort within your home but also contribute to extending the overall life of your roof, protecting your investment for years to come.

Why You Need To Upgrade Your Attic Insulation
Your attic plays a vital role in your home’s overall energy efficiency and comfort, acting as a crucial barrier between the outdoor elements and your living space. Without proper insulation, warm air escapes through the roof during Ontario’s cold winters, leaving your home feeling drafty and forcing your heating system to work overtime. During the summer, heat seeps in from above, creating uncomfortably warm living areas and uneven temperatures throughout your home.
The most effective way to prevent these issues is with spray foam insulation — the top choice for attic insulation in Newmarket and across York Region. Spray foam forms an airtight seal that blocks heat transfer, stops air leaks, and prevents moisture intrusion far better than traditional materials like fiberglass or cellulose. This high-performance insulation keeps your home consistently comfortable while reducing strain on your HVAC system and lowering your monthly energy bills.
By upgrading your attic insulation with spray foam, you’ll experience:
- Up to 30% savings on heating and cooling costs through superior energy efficiency.
- Protection against moisture and ice dam formation, preventing costly structural damage and mold growth.
- Improved indoor air quality and comfort, eliminating drafts and reducing airborne allergens.
- Increased property value, as energy-efficient homes are more appealing to today’s buyers.
Choosing spray foam attic insulation isn’t just an upgrade — it’s an investment in your home’s performance, comfort, and longevity. With professional installation from Newmarket Spray Foam Insulation, you’ll enjoy year-round comfort, lower energy bills, and lasting protection for your home.
