Professional attic insulation for Randolph property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
Attic insulation with spray foam in Randolph, NJ delivers immediate comfort improvement and measurable energy savings. Our closed-cell foam creates a continuous air barrier from ridge to eave that fiberglass and cellulose simply cannot match — no gaps, no settling, no thermal bypass.
In Randolph, NJ, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every attic insulation project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every attic insulation project we complete in Randolph is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
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.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
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 commercial building needed a roof solution that would not require tenant relocation. The restoration approach was perfect — no tear-off noise or debris, minimal odor, and a fully warranted system installed in under two weeks."
"Our flat roof on a strip mall had been leaking for months. Two other companies just slapped tar on it. These guys actually found the real problem — failed flashing at a parapet wall — and fixed it permanently."
"Our crawl space was damp, musty, and completely uninsulated. They sealed all the rim joists and band boards with closed-cell foam. The floors above are warmer and the moisture problem is gone. Should have done this years ago."
