Get matched with top nest installation pros in Washington, DC

"The contractor did a beautiful job with a somewhat complex installation of crown molding in basement to cover some electrical -- it required him to work around windows and tiny corners. it looks amazing."

"They came out and did the gate install.  They were professional and on time.  The only thing, my gate opens in instead of out towards me.  I am calling them to come back out and make the adjustment."

"Christian did an efficient and phenomenal job assembling tv console with fireplace. I am impressed just by how well it was built and how sturdy it was. it looked like a two person project but he did it independently. After assembly, he supported with taking the furniture to the room of choice and positioning of furniture. Christian arrived promptly and was very kind. Professional and prepared! Highly recommend! 5 stars"

"These guys were quick to come to the house and walked me through the rats nest that was my AC control system. They diagnosed my need to for a new compressor and demonstrated the problem with the wrrrrr-chunk noise a locked -up compressor makes. They didn’t upsell me for a whole new system like Magnolia did, or overcharge by 30% more like another company did. They replaced the compressor including unraveling other HVAC techs bizarre wiring in under 4 hours and gave me pointers on what to look for to avoid problems in the future. Straightforward and honest, I couldn’t expect more from an HVAC tech."

"I am totally pleased with the EV charger installation performed by Kevin and crew. Work was done with the highest degree of professionalism. They took care to route wiring with a minimum of disruption to walls and ceilings. Beautifully done! Kevin made it easy for me, arranginh the building permit and county inspection . Highly recommended!!"

Arrived promptly, very courteous, two guys which I wasn't expecting but all the better. Assessed the overall situation and got to work. Worked efficiently and neatly on the projects. Hit a snafu with the sink upstairs. They broke the drain in the sink. They did the right thing and went to Home Depot, purchased another one, and installed it at no charge. However, they lose a couple points since it was a different color chrome (original was satin nickel) and it drains significantly slower than the old one. So slow that if I leave it running while brushing my teeth the basin will start to fill. (Probably shouldn't be wasting water like that anyway I guess?) Anywho, they ran out of time for one project (the drain took up a lot of time) which I was only okay with because two of them showed up instead of one which I wasn't expecting (coupon said 1) nor did I pay for.

"Terrific, we decided to go w/ Stoneberger because their sales representative spent time advising and guiding us through the options, the colors and styles of doors. She listened to what we thought we wanted and helped us find the right solution. No other sales rep we met with offered that customer service. She also followed up on time and was super easy to work with once we decided on specific doors. Installation also was on time, efficient and went very smoothly. We had one issue that arose b/c of the age of our house and Stoneberger addressed it quickly and beyond fairly. Highly recommend them."

"We had them install all the roofing and other hardware for a full Tesla solar roof. Once that project was going, we also had them do 5 outer window/door projects for us. All went well and we're happy we had them do everything!"
