Rainbow Insulators

Aug 2025

These guys are top-notch insulating pros. They did everything they said that they would do, communicated clearly at every step and gave good value for the dollar. I have an old house-- I needed them to fill my basement sills (aka: ring joists) with insulation foam to cut the drafts and fill in any little holes (big enough for bugs or mice, who can squeeze down to nothing to get in in the winter). This improvement is going to make a world of difference in my house health. Bing (owner) explained everything and he did it at my level, so I knew what to expect for the installation and I know what to expect going forward. Very satisfied!

I know it is hard to get excited about insulation but Rainbow Insulators did a top notch job insulating my garage prior to me installing a furnace. I have sixteen and a half foot tall ceilings at an 8/12 pitch and they blew packed cellulose between the rafters and put vapor barrier over everything. The quality far, far exceeded my expectations. Thank you!

I had Rainbow Insulators blow in attic insulation in my 40*50 Cleary building. They gave me a bid over the phone, we scheduled a date two weeks out, they showed up when they said they would, got it done with very little mess, and sent me a bill for exactly what they quoted me for. They will be my first call if I need work done again.
