“It was a pleasure working with Carlos, who is great at communicating the work that has to be done and the possible outcome of that work. He is patient and knowledgeable, and I completely trusted him with my home. I have a house that was built in 912 and the basement is only partially dug out and has dirt as insulation. This was not an easy job. Carlos was professional, transparent and efficient, and even helped me communicate with my contractors who were rebuilding the wall that was being insulated. He went above and beyond, in this age of fast bucks, he took the time to ensure the job was done right.”

“Can’t say enough good things about this company!! From the initial quote to install and post inspection, the beyond foam team surpassed all expectations and has amazing customer service! I had them spray the warm floor above my garage and also garage attic fixing poor workmanship from the initial builder, very impressed with the outcome our rooms are now sealed and warm with no future worries of heat loss or potential condensation issue. They use an awesome product and the work is complete in a very timely manner. Also the cleanup of the work area was better than when they arrived! Invoice was to the penny of quoted price. Look forward to doing business again!!” 

“I went with blown in insulation on top of a layer of foam (hybrid system) to keep cost as low as possible.  I have an older house in which vapor barrier is very thin in spots not missing completely and none of the junction boxes had any vapor barrier at all.   I chose to go with the hybrid system that gives you a vapor barrier protection with the foam and the blown in insulation on top gets your R value up without the high cost of going completely foam. Cost was about 1/3 more expensive than going strictly blown in insulation.”

“What an incredible team! James, Jay, Lenny and all the staff behind the scene at the office were  phenomenal.   Where do I begin… Professional,  knowledgeable,  eager to teach (showed us everything they were  doing so we could understand), efficient,  accommodating and sensitive to the finances. Jay and Lenny spent many hours ensuring everything was perfect. The fact that every individual had experience in many other areas of house repair/ maintenance/ construction meant they could tie everything together for us. Their firm quotes were very helpful for budgeting.  No surprise bills at the end… accurate to the cent!” 

“Very impressed with their work on the insulation and drywall installation of my garage. Their price was competitive and their craftsmanship exceeded expectations.  All of the wiring including the garage door opener, LED lights and driveway camera were re-installed properly. I still have to tape and paint the drywall but the work looks very neat regardless. All the batt insulation was completed the first day. The ceiling blown in insulation and drywall installation was done on the second day.”
