Cornerstone suppled us with a reasonable estimate. They installed gas lines in a timely and efficient manner. They removed minimal ceiling sheetrock to gain access for installation.

I have used them a few times now. Most recently was when I had 9 pipes burst in my garage. The guy that came out was here for 4 hours. His brother arrived to help finish up. My total bill was a fifth of what I was expecting to pay! They were so kind and professional. On a different trip, the job only took about 20 minutes, so they only charged for price and not for service. I asked them if they knew anyone who could help with the drywall, and they gave me a great reference.
