Mike was very professional. He let me observe the entire installation and was very responsive to all the questions I had. During the install, he was meticulous in making sure all the wiring was clean. I would definitely hire him again for any electrical work that I might need in the future.

I think this is a great company. Uniq Installs was the first company to reach out to me almost immediately after I listed my home project. I hired them to install my wired Google Nest Doorbell and they knew exactly what they were doing. Dan and his employee were kind, prompt and professional....

Doorbell Installation questions, answered by experts

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
