USI San Diego

The good part about my experience is that the wall insulation is very effective in keeping the house cooler in summer and warmer in winter. However, I was extremely disappointed in the workers who came to do the job. They were like Barbarians in their disregard for the possessions in the house. They knocked over a very expensive porcelain lamp (luckily, it did not break) and knocked a shade off a door in their haste to do the job as fast as possible. They covered some places with plastic, but the worst part was they did not cover the closets and a layer of dust covered all our clothes and shoes. Then, there was a disagreement in what their scope of work was. They did not insulate a wall and had to return at a later time to finish the job. They cracked a wall, but they did acknowledge it, and the company sent a repairman to fix the crack. They were not careful about anything, and I could never recommend this company to anyone!

I hired John to install spray foam insulation in our crawl space under our house to help warm up the floor, and our feet. John came out to do the site survey and, at first I was not impressed but his company was the only one I could find on Home Advisor that actually used spray foam insulation. USI’s quote was a bit higher than I expected but, after doing some research about prices in other parts of Southern California, I was a bit more at ease. His workers did not speak much English but anytime I had a question they didn’t understand, the head guy called John up on his cellphone and we worked things out. We even worked out a job modification over the phone and by the time I got back to my living room, my fax machine was printing out the new work order. They did exactly what was on the job order, no more but no less. I was fine with this as none of the workers could be tempted to do something or add something that wasn’t agreed to. I would hire them again for the next insulation job we have.

Pros:
1. Showed up on time
2. Salesman speaks English
Cons:
1. The whole team that did the work didn’t speak English. Had to repeatedly go back and forth over the job scope. They came with a drawing and had a hard time following that. At one point they started packing up when they forgot a whole section that I had to point out.
2. Left a big mess (the prime who they subbed through took responsibility). Salesman told me they would put plastic sheets and clean up after themselves. They put a few plastic sheets but did not cleanup excess insulation that was all over the place. They also failed to cover all areas so for weeks after I found insulation in hard to get corners, etc…
3. They cracked some drywall and when I pointed it out they just acted dumb. (Prime took responsibility for this too) When the workers don’t speak English you’re not left with many options.
4. Just measured and they didn’t do R38 /​approx 10 inches of insulation which is what the order stated.
Don’t trust them!

John Frederick was the sales representative who came to my house to give me an estimate for insulating my attic. He is extremely knowledgeable, friendly and professional. I knew nothing about insulation and he took his time in explaining the differences between fiberglass and cellulose insulation. He gave me his professional opinion on which one I should get and the reasons why. He also answered the myriad of other questions I had.
John gave me an excellent bid and USI guarantees their work. I would not hesitate to refer anyone to USI if they need to have insulation installed.

I’ve used this company to insulate my attic and my existing wall by «drill and fill» with cellulose/​boric acid insulation. They are the best! Very generous with the amount of insulation they provide, on time and very affordable. They missed one small, three foot section in a closet, but I’ll call them and I’m sure they’ll come back out to finish it. I highly recommend these guys if you want to cut out the middlemen, get a quality product and save money. Thank you USI!

Used them to insulate my new extension and my attic. They were terrific. Though I forgot to ask them to insulate my French doors which were not part of the plan, they came back to do that free of charge. Thats service! I would highly recommend them.
