"He showed up in a timely manner. He did the job quickly. There was a shorted wire that he had to re-run and pull through the existing pipe. So far it's all working great and has not needed to return. So far everything working great."

"Removed old opener and installed new one - the old one was too noisy.   This was after I had him come out once only to find out that I did not have the extension that was needed.   He came again after the part I ordered arrived.   Very fast work and perfect.   He must have lubricated everywhere on the door because everything is extremely quiet now.   I would definitely use them again.

"We first hired Chris of CQ Painting after reading good reviews on Angie's List in 2012. We hired Chris for exterior painting which included replacing and painting wooden trim around the windows and doors. Due to the good work initially, I have hired Chris multiple times since, including the skim-coating/painting of two rooms (once to cover up splatter paint decorating and the other to fix another company’s wall paper removal gone bad in our powder room). Most recently, we hired Chris for drywall repair/painting associated with a kitchen/family room refresh; during this project, I learned learned Chris’ company was expanding into other areas and I subsequently hired him for an interior door project and to install several lighting fixtures in our dining room and foyer. Everything turned out beautifully. In all the jobs for which he was hired, Chris and his crew arrived on time, have always been respectful, pay attention to detail, and are great at cleaning up afterward. Due to the above, Chris has become our “go to” guy whenever we have a painting-related project! I would definitely recommend Chris and CQ painting!"

"Chip (aka Bob) Newren came out and gave us an estimate based on our home being approximately 2000 square feet. He gave us 2 options, the package we chose listed above, or  for about $2000 more we could have gotten a 95% efficient heater and SEER 16 AC.
After reviewing the government sites, that $2000 would take 11 years to recoup - so we went with the more basic package.
The installation was set up 3 days later. The install crew were informative, efficient and just a pleasure to be around. The install takes all day so this is not a small matter. It turned out that Chip had measured incorrectly and the heater we chose would not fit. They decided to upgrade our heater to a version that WOULD fit properly at no extra cost.
This is above and beyond - the stand by the estimate and didn't try to up-sell me once my decision was made. All around, it was a great experience. This company absolutely kills it with their customer service and honesty. We no longet do business with anyone else regarding plumbing, heating and air. 
Do yourself a favor and call Chip.

"Gus was perfect for outsourced handyman services. Not only did he do a perfect, fast job of installing my ceiling fan, but he advised on the best way to approach the project."
