Professional attic insulation for Markham property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
If your Markham home has hot upstairs rooms in summer and cold drafts in winter, your attic insulation is failing. Lapolla Industries replaces underperforming fiberglass and cellulose with spray foam that seals every gap, fills every cavity, and delivers R-6.5 per inch of insulation value.
Property owners in Markham trust Lapolla Industries for professional attic insulation because we combine industry-leading spray foam technology with the local expertise needed to address Illinois climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our Markham attic insulation crews arrive fully equipped with the latest SPF application systems, safety equipment, and premium materials. We handle every step — from surface preparation and substrate evaluation to final coating and cleanup — so you get a turnkey result with zero hassle and complete confidence in the finished product.
A systematic approach to attic insulation that ensures lasting performance.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

"Our metal warehouse roof had been leaking at the ridge and sidewall transitions for years. The coating crew sealed every penetration, fastener, and seam. Completely watertight now and the energy savings are a great bonus."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."
