I'd rate them a 10 if it were feasible. These folks did an absolutely superb job insulating our walls, attic, crawl space, and cellar and even repaired a cracked beam and attic ventilation. One of the challenges was that there were several open spots around our radiators, so blowing insulation in the wall, without blowing it into our house, was tricky, but these folks did it with ease. The team was friendly, professional, and respectful and they left the place spotless. And: they beat their estimated schedule. Many thanks for outstanding work.

We had a crew work on our old and un-insulated 1955 cape and they did great work.Dan kept the tasks moving right along with pride in his work and outstanding results.Everyone was polite, courteous, professional, and skilled at their jobs. Plus they were patient with my questions and educated me on what the various tests were for.A knee wall space looked like a massive pain to me, especially the dormer, but they tackled it with ease and I'm very happy with their finished work.I'll highly recommend TheWeatherizeGuyz to our neighbors and anyone that mentions making their home weather tight.Your work will make this winter more comfortable (and affordable!).Thank you again and I can't say enough nice things about Dan and your entire crew, they were phenomenal!

Mike and his crew came to our house do insulate our attic, build a storage platform up there for us, and insulate our basement and garage. They did a fantastic job, they were thorough, attentive to detail, really did a great job cleaning up after themselves, and were on time for both mornings they were scheduled to be at the house. After I'd paid the invoice, Mike emailed me to say he'd used less material that originally quoted, so he sent me a refund check for the amount I'd overpaid. He could have pocketed that and I'd never have had any idea. Standup, honest guy with a really hardworking crew. I'd recommend them to anyone.

The crew showed up 5.minutes early and ready to work. They came in and introduced themselves, took very good care of our home while fixing our attic and basement insulation. Clean up was top notch, every employee had a great attitude and was a pleasure to work with. Very good at their trade, highly recommend and if you think your house is well insulated give these guys a call and find out. They sealed and insulated more things that I could imagine. Well worth the money. Thank you waetaherize guys. Great job

Very professional hard working crew, attentive to detail, respectful of property and on time. Took about 1 1/2 days to blow insulate 2 very tight crawl spaces and the attic with a new cut out hatch door. While working on a vent pipe on my roof, he even took out a couple of old satellite dishes since he was up there anyway. Absolutely recommend this company.

Fiberglass Insulation (exterior walls, cathedral ceiling, garage ceiling)Mike and his team were extremely professional and provided exceptional work. His quote was reasonable for the amount of work that we had him complete in our 1,000 sq ft addition.
