Mr. Ranse and his team were highly responsive and professional throughout the project. They executed the work as per the agreed plan and completed it within the expected timeframe. We found their services to be the most cost-effective option for our generator installation project.

Amazing work by the DEM team! I worked primarily with Ty and Mandi to coordinate the work and they were extremely responsive and accommodating. Even the owner Ranse was willing to connect on a call to answer my questions. The electrician, Adam, and plumber, Jeremy, completed phenomenal work and I am very pleased with the outcome. The company even promised to address any issues should they arise.

Details: Stationary • Emergency backup • Gasoline (most common) • No, but I plan to purchase the generator
