I was very happy with the work performed. The workers were very polite and professional. The work was completed quickly and as expected. My overall experience was very good and I would always consider Fiberclass before another company for any building needs. I highly recommend their work. Bryan, South Lyon, MI

I wanted to say thanks for taking the time to do such a complete evaluation of the moisture problem we were having in our attic. I wanted to let you know we had a great experience! The siding guys came out and performed the work quickly and pointed out that in addition to the painted over vent covers, our actual vent openings were only about 3 inches in diameter. The guys opened these up more and vastly improved the ventalation in the attic. The insulation guys came out and were quick and very clean. They took the time to lay out plastic on the carpet to minimize any mess plus were really great about cleaning up after themselves. We are definitely noticing a big difference since the work was done and have been able to adjust our thermostate accordingly. We're actually a bit excited to see our next heat bill to see if we see an improvement. Chris, Ypsilanti, MI

Just wanted to let you know we are VERY happy with the work from all the Fiberglass staff. Aaron did a great job finding ways to improve our home. Jeremy did a great job with the spray foam. Jason and Dan made sure I checked everything and was happy before they finished. Them even stayed and cleaned up – they were great. Dan Starick was willing to work on our access door on Sunday. I’ll definitely use Dan and Fiberglass when we finish our bonus room and basement. The guys showed up on time, worked hard and cleaned up. All items quoted were done as promised. Am I happy with all the Fiberclass staff – Yes. Would I recommend them – I already did. Thank you, Xavier Cardenas

Dear Aaron, I just wanted to let you know how much I appreciate everything you have done to fix each and every issue happening in my house! As you know there were several different things going on that needed to be addressed and it took a lot of time to inspect and get it right. I work for a roofing magazine and I read all the time about nightmare stories with contractors. I have had them myself, however, you set the example as to how a professional contractor should run a solid clean business. I also appreciate how you took the time to really dig into the attic and truly understand the nature of the problem and come up with the answer that was specific to my house. Your team was extremely professional, courteous and I was shocked to see how well they cleaned up after themselves! You and your team, hands down, exceeded my expectations! Thank you very much for an amazing job well done and anyone who hires you will know you really do treat their house like it’s your own. Most Sincerely, Jill A.
