Allcare Insulation Removal And Installation

I did not have a good experience with this business.
At first, the owner was very responsive when providing a quote, but after cash was paid no response at all.
Insulation was installed too close to halogen lights.
At the rear of my house I discovered R 2.5 insulation was being installed instead of R 6 as quoted. Although the company owner said he would would install the insulation non-english speaking workers attendedso it was difficult to clarify what they were doing. No certificates provided or receipts as promised.
I remain unclear as to what they actually did in my roof!!
