Terrible plumber. I used them on my new build in 2006 and since then I've had to put $5000.00 in repairs. They used galvanized steel with cooper fittings on some of the plumbing in basement cost me 1500.00 to fix that. They didn't use sanitary bolts to fix all the toilets to the floor the bolts rusted out had a plumber come out and fix that. Now I have to spend another $3500.00 to fix more of the his sub-standard work. I used them for my heating and cooling as well. House has to be set too 74 degrees in the winter to keep the temp in the house at 70. Air conditioning quit working back in 2012 because the didn't seal the power cable coming into the house the line got wet and that had to be replaced. All in all pay more and save yourself a ton of money down the road. If I could give them a zero star rating or negative that might show how disappointed I am with this company. 1 star is far to generous.
