Professionals all the way!

Potomac Backup Generators came and installed my home system 5 years ago. I look forward to seeing them every year when they come to maintain it. Having elderly parents with medical equipment, this was a must. We definitely picked the right company.

The Best!

Ewell Builders (Gernot Ritzau) installed a Generac 22KW generator at my home in Potomac, MD where we frequently lose power. Gernot was wonderful to work with. He explained in easy to understand words the installation process, the different parts of the system and how it works.
The installation was well planned and executed with no disruption to our routine. His workmen cleaned up every day. Our installation required a trench around the back of my house and the earth was properly restored upon completion of the project. I recommend Ewell Builders highly. I have owned this house for 37 years and have had dozens of contractors work on it. Ewell was one of the best.
