She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end.

"I called a few different companys for them to come out and give me an estimate on what i had in mind to be done. (3 total) One company made me feel dumb for not being sure on what i wanted exactly done. The second company give me a crazy high bid even after i told them im working with a budget, and the thrid company was copperhead contracting which turned out to be the company i went with. They game me an estimate that was lower then the first two and even helped me decide on things i didnt have picked out like the type of windows i wanted, even down to the knobs for the cabinets! Now i felt better after talking with them so i did hire them as my contractor. It took them a couple of weeks to get it done however it turned out better then i had imagined! The crewmen came across a few difficulties but they handled it well. Id like to say it was worth hiring copperhead contracting. Id love to work with the same guys for any of my future projects."
