"They were great! They did the job without us even being home, accessing our house from a key box. That was very convenient. Only issue was that they had to schedule us out 2 weeks- they are busy!"

"Neil did the job fantastically and explained what he was doing throughout, always asked for an inspection to make sure it was done to my satisfaction. Pricing was extremely fair and he was timely and quick. Would highly recommend for any insulation work you need done. Can’t speak on the other work he does, but if it’s on par with what he did for me, then you’d be doing well."

"Bobs work, attention to detail and pricing were outstanding. I've been looking/needing a Handyman since purchasing my home 3 years ago and may have found the guy in Bob! He kept me informed of when the service would be done and an issue that arouse during the work. We talked about best solution and moved forward from there. My neighbor has been waiting for me to give him the referral of Bob's work as he too is needing a skilled Handyman......Bob has earned my referral!"
