Spray Foam Insulation in Allentown, PA

Robert and Otis came to our home and spray foam insulated our 2 car garage. They did a great job. They were professional and knowledgeable. The spray foam was applied neatly and evenly. They cleaned up after the job and left the place as they found it. I have since heated the area (it’s winter) and the difference is overwhelmingly noticeable. I would definitely use them again and recommend them to anyone.

I have worked with this company for years and have suggested them to many homeowners. They have never disappointed. They provide the highest quality service and energy efficiency measures. Anyone looking to become more comfortable in their home while saving money needs Custom Weatherization.

Dylan and Oz did a great job today. Insulation in crawl spaces, new exhaust fan in bathroom, insulation in basement and around door. Very polite and efficient. I would highly recommend this company!!

Fantastic service, timing, and price. Gerald and his crew were consistently a pleasure to work with, and provided excellent care of our home, windows frames, and floors. The before-and-after photos were impressed and greatly appreciated. You won't do better (or, dare I say, as good). Highly recommended

After installation of blown-in cellulose insulation, our house feels warmer already!!! All communication happened directly with the owner, Gerry, who was very accommodating and reassuring. "Whatever it takes to make you happy." On installation day, the installers were courteous - respectful of the home both during installation (putting down tarps, protecting walls from scuffs, etc.) and after installation (cleaned and vacuumed to leave no trace behind). I shopped around for this project and am very happy with my choice. I would happily recommend Lehigh Valley to a friend or family member.

This company was very reasonable priced, polite, clean, and efficient. They knew what they were doing, they cleaned up everywhere they touched, and showed up on time. If you need insulation work done, this company is amazing. Thank you guys

Travis, Joe and Chris were super professional. They worked very hard and finished the job. The cleaned everything up and made sure to double check at the end. We were very pleased and we are excited to have an insulated home!

A great and friendly company to deal with. I had to reschedule once because the electric hadn’t been installed and it was an easy process. They showed up on time, finished within the estimated time they gave and no surprise cost or extra charges. They cleaned up all the studs and made it very easy to finish the job. I highly recommend.

You may find lower estimates. But you’re not gonna find the quality in workmanship, craftsmanship and attention to detail as USA insulation. John is a fantastic representative to work with. And the crew (Travis and crew) that did the work are very conscientious and extremely friendly. It always pays to do the job right the first time. My garage now that it’s insulated is so much warmer. Thank you

I used ASI to insulate my home and business. The office had a flat roof that was inadequately insulated from the 1960s and ASI did a wonderful job. At my home, although it was much newer, I was surprised to learn that the fiberglass insulation was only doing an "adequate" job and so I had my entire attic insulated with spray foam. I am looking forward to seeing the benefits in energy savings. I expect that energy costs are only bound to get more expensive in the future, and so a stitch in time, saves nine. I was very pleased with the ASI crew's knowledge and thoroughness. Dealing with fiberglass is a messy proposition and I'm glad to have it out of my life. I cannot recommend the folks at ASI enough.

I now after 8 years have my entire 1890 farmhouse sprayed by Asi. The employees are very trusting and do a great job. They went out of their way a couple times to expedite me to keep my projects moving forward. Would and have recommended to a lot of people. Thanks again to the Asi team

Great job on an old, wood frame, house in North Catasauqua. They insulated the attic with 8 inches of spay foam insulation. When they first sprayed the insulation, we almost left it the way it was, it looked like the Batcave. 🤔🤓😂 They shaved it off, and it gave us a great smooth surface to work on with drywall. They showed up on time, and did a great, great, great, job. Outstanding, hard-working crew. It’s almost like an artist working with a different mode. He knew the reaction time of the foam, so as not to waste it. As it cures it expands. And he knew within a fraction of a second, when to stop. If you leave the trigger on longer It creates more foam, that would have to be shaved off later. A true technician working with Precision. When it was all done, it cut our heating bill by almost 40%. A 4000 square-foot home, including hot water, for only $115 a month on gas. It does have a setback thermostat though, to 65 at night. From the estimate to the finished product, we can not say enough. Everything went perfect. We can’t thank them enough. We would recommend them to anyone, residential or commercial.
