NEVER AGAIN! The customer service was horrible! They delayed the work, they didn't return calls, and they didn't listen to my request or offer suggestions.
I'm giving them a star, because I think the pricing was good for what they were asked to do. However installation was so poor, I should have paid half! Their measurement were all off, and to compensate they broke plaster walls and filled gaps with silicone. The edging and joint seems are 1/4 inch. 1/8 is reasonable and what I requested.
The opening for my slide-in stove was cut too small, but they re-cut, they didn't cut the opening evenly so the stove is butted to one side leaving a larger gap to the left. This was something I warned them about.
Please, use someone else and save yourself the headache. It's worth the extra cash.
