Areas We Serve

We are Proud to Serve all of Northern Virginia, Including:


R.A. Dobson is located in Sterling, just off of the Dulles Toll Road. Our technicians have years of experience working in the 17 Sterling neighborhoods, from Lowes Island to Sterling Park. Homes in Sterling, VA were mostly constructed in the ’80s and ’90s, and have been appreciating steadily since initial construction despite the 2008 housing crisis. Homeowners are aware of this trend, and know how important it is to protect their homes from the damage that can come from plumbing and HVAC problems. Given that Sterling is also a red-hot real estate market, R.A. Dobson technicians can help avoid these problems with fast, effective, and expert service.
