Dan came out the next day after I called. Marco had the written quote to me 48 hours later. Crew showed up on the date they said, finished in four days, cleaned up every night. The attic is finally warm and we slept with the windows open last night. Not one thing I would change.

We got three quotes. Long Island Insulation was the only one that showed up when they said they would, gave us a written quote with line items, and actually called us back. The first oil bill was $420 lower than last January. Price was fair. Would use them again.

The spray foam in our basement made a huge difference on our heating bills. The crew was professional, on time every morning, and they treated our property like it was their own. Dan even stopped by to check on progress. That is how a contractor should operate.

We wanted spray foam insulation in our crawl space. Dan told us the honest pros and cons, did not try to upsell us on anything we did not need, and the finished result is a dry, sealed crawl space with no more musty smell. Neighbors have been stopping by to ask who did it.

Historic district, HOA review, tight setback. Dan handled all the paperwork and the crew nailed every detail. We had a very specific color from the ColorPlus line and it matched the architectural review board requirements perfectly.

I was losing $1,200 a year on heating a drafty house. Insurance was a nightmare. Dan dealt with the adjuster, got us a fair number, and had the crew out within ten days. The house looks better than it did before the storm.

From the first phone call to the final walkthrough, everything went exactly as they said it would. On schedule, on budget, cleaned up. They found vermiculite in the attic and coordinated the abatement before starting. No shortcuts.

Third contractor we called. First two never called back. Dan called back the same day, came out the next morning, and Marco had the quote that night. That is how it should work. The Hardie plank looks amazing. 10/10.

I was nervous about the cost but they were upfront about everything. No hidden fees, no change orders. The crew was polite and cleaned up every single day. My house finally feels comfortable all winter. Could not be happier.
