"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.
I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"First and foremost if i could give Solorios Insulation Services 10 stars i would. The work completed was exceptional. Every step of the job from the beginning bid to the last part of the clean up was better than expected. The work was completed in the time they said it would be and (Jesus) was a stand up guy to have working in our home and paid attention to every detail that meant so much to us. I cannot say enough of how happy i'am with this company. We definitely will be calling them again in the near future i highly recommend them. Thank you!!"
