Basement & Crawl Space
★★★★★
February 2025

My first floor was always freezing in winter — I had area rugs everywhere just to deal with it. After they sealed the crawl space with closed-cell spray foam, it's like a completely different house. Warm floors, no more drafts. Quote was fair, they showed up on time, done in 6 hours. The crew was clean and respectful of my home. Highly recommend to anyone in East Orange or Newark dealing with cold floors.

Response from John Sullivan, Owner

Tamara, cold floors from an uninsulated crawl space are one of the most common issues we see in Essex County homes. So glad the closed-cell foam made such a big difference for you! Thank you for trusting us with your home.

Used them for our 8,000 sq ft warehouse on McCarter Highway. Got the quote Monday, job started Thursday, done by Friday afternoon. Amazing efficiency. The crew worked around our operation schedule and the quality of the spray foam work was outstanding. Our warehouse temperature is now consistent and our tenants stopped complaining. Will definitely use them again for our second property in Irvington.

Response from John Sullivan, Owner

David, commercial jobs like yours are where spray foam really shines — that 8,000 sq ft space should hold temperature much better now. Looking forward to helping with the Irvington property when you're ready!

Got 3 quotes for our Montclair attic — this company was not the cheapest but their thoroughness during the estimate was completely different. John explained the R-value difference between options, the NJ rebate program, and the long-term ROI. The other companies just gave me a number. Job was done beautifully. Definitely worth every penny and the rebate brought the cost down significantly.

Response from John Sullivan, Owner

Sandra, we appreciate you taking the time to compare options — that's exactly the right approach for a project like this. The R-value conversation is important and we never want a customer to make a decision without understanding what they're getting. Thank you for choosing us!

Had them do open-cell foam in the interior walls of my Irvington home — mainly for soundproofing between the bedrooms. The difference is incredible. You can barely hear anything between rooms now. Miguel the technician was fantastic — explained everything he was doing and the cleanup was immaculate. Diane in the office also helped me understand the rebate process clearly. 5 stars all around.

Response from John Sullivan, Owner

Kevin, open-cell foam for soundproofing is one of our most requested services in Essex County row homes — so glad it worked out so well for you! Miguel and Diane are both rockstars and I'll pass along your kind words to them.

Insulation Removal & Replacement
★★★★★
October 2024

Our 1940s West Orange home had ancient fiberglass insulation full of mold in the attic. They removed everything safely, treated the wood for mold, and installed new closed-cell spray foam. The team wore full protective gear, contained the work area perfectly, and I never felt worried about contamination. The attic is now cleaner than it's been in decades and our AC bill dropped 30% this past summer.

Response from John Sullivan, Owner

Angela, old fiberglass with mold contamination is a serious issue and we take the removal process very seriously for the safety of your family. So glad we could get that attic cleaned up and properly insulated. That 30% AC savings in summer is exactly what closed-cell foam delivers!
