"I can't say enough about working with Diane at Carriage House II. I found them via an internet search. Diane keep me informed about every step of the project. Two of the chairs were done in a beautiful large paisley print, which they perfectly matched. The other four were done in a subdued brown tweed, subtly picking up the colors in the paisley print. They not only upholstered the chairs, but also strengthened them and fixed a broken one. The chairs are better then they have ever been. I can't thank them enough. My dining room has a designer look with these "new" chairs."

"The company represented to be competent and experienced at bathroom remodeling however the worker, Joel was not able to complete the job efficiently. He installed a shower liner over a shower body which he had improperly installed which caused leaks and a situation where we had to break through a wall to get to the improperly installed shower body to fix it. We supplied the materials including the shower body which he did not use but instead left the old one in which doesn’t quite fit with the new shower handle. The toilet was loose and crooked also not sealed on the bottom as per code. When I pointed out to the worker that he had caused a leak, water was pouring into my basement he attempted to charge me an additional $100 to fix his own mistake. The tiles were not properly spaced so some were too close to receive the black grout that we had intended to distribute over the whole tiling project, it remains unevenly grouted. With the uneven spacing it is impossible to grout properly. Overall a disaster of a job, most of the work he did had to be redone."
