"Groundworks did an excellent job with my house projects. Their crew (Lee, Rick and Brad) were excellent. They arrived ahead of schedule and began work immediately. I was kept informed every step of the way and was invited to observe while they explained what they were doing. I would highly recommend Groundworks to anyone needing foundation stabilization."

I'm Davitt M. Armstrong -- "jack-of-all-trades and Master of One"; with a Master Plumber's License here in the great State of Colorado. I'm engaged in highly custom plumbing and hydronic heating applications for discerning clients; with thirty-five years of highly pleased customers. I also provide utterly unbiased and extremely comprehensive home inspection services for buyers and sellers, for a select group of local real estate agents.

"Davitt was out within a couple of hours of calling. He is a really great guy. I do a lot of my own repairs, but after doing a bunch of troubleshooting on the in floor system, I knew it was time for a pro. He took time to work through explaining the system to me as this was the first house we have had an integrated furnace, water heater and flooring heat. It turns out he was the sub on the original 2015 construction. The issue was a bad control panel that operate the zone valves and furnace. Rather than go get the parts himself and incur more costs, he allowed me to go get the parts for him. That allowed him to spend the time pulling the old unit out. One thermostat needed replaced in addition which I did while he was putting the new control panel in. Yep, just see how many contractors would work with you to save costs by you working with them. He also provided the contact info for the other original subs on the house which is awesome info. The parts costs were very reasonable. They could have been easily inflated to double the material line item amount as control panels are typically very expensive components to any specialized system. To address the D rating review. You should have told him this was an insurance claim in the first place. Good luck getting folks to give you itemized materials list. Would you expect a carpenter to give you a materials list on every size board, nail and screw. Your expectations were unrealistic. After all this was supposedly an insurance claim. They are the ones to take it up with unless you were trying to pocket the difference. We are planning to construct another building on the property and will be strongly supporting Davitt as the sub for plumbing and heating."
