A fitted door with smooth, tested travel — across Bethesda, Chevy Chase, North Bethesda, Rockville, Potomac, Glen Echo.
A new garage door installation replaces the old door with a complete system fitted to the opening and the chosen door. We check the frame, available headroom, and opener before settling on a design. Tracks guide the door, while springs counter its weight so the opener does not have to lift the full load alone.
Across Montgomery County, we compare steel, insulated, wood, composite, and aluminum-and-glass doors, plus panel designs and window options. Insulated panels slow heat transfer, and the R-value describes how well they resist it. We also consider whether the opening needs a wind-rated door or reinforcement under applicable requirements.
After the measurements and door choice are set, our crew releases the old springs’ stored force before taking down the door. We install tracks and springs suited to the new door’s weight, fit weather seals, and retune the opener. Our truck carries installation hardware, fasteners, and measuring tools. Before we leave, we confirm the counterbalance, smooth travel, and safety reversal.
We match a new garage door’s panels and bottom seal to the garage’s exposure to heat and freezing nights. Summer afternoons here average about 88°F, and winter nights average about 32°F. When we arrive, we check the opening, track spacing, spring balance, and floor contact. If the garage is attached or used as a workspace, we discuss insulated panels to slow heat transfer. We install the door, cycle it to check smooth travel, and adjust the bottom seal to meet the floor evenly. We leave the door aligned, with its safety reversal checked.



A crew member asks what you notice about the current door and what you want from the replacement. We set a visit to inspect the opening and existing setup.
We check the opening, headroom, frame, and opener, then review door options. Before work begins, we provide a written quote for the selected door and installation.
Our crew releases the old door’s spring force before taking it down. We fit the new tracks and weight-matched springs, install the seals, and adjust the opener.
We confirm the door travels smoothly and closes against the seal. Before leaving, we check its counterbalance and test the safety reversal.
Starting prices. A door has two lift cables and one or two springs; the exact price depends on the door, the hardware grade and how many parts are replaced, and is confirmed on site before any work starts.
