Sliding Door Installation & Repair in Rockville, MD
Stop fighting a stuck patio slider — roller, track & glass repair plus full new installs across Rockville, Potomac & Silver Spring.
When a sliding glass door takes two hands and a shoulder to open, it's almost always the rollers or the track — not the whole door. NextDayJose repairs and installs sliding patio doors across Rockville, Silver Spring, and Bethesda: we replace worn rollers, straighten or cap bent tracks, rebuild the lock, and swap fogged or cracked glass. When a door is past saving, we install a new energy-efficient slider start to finish. Locally-owned, 13+ years in the DMV.
A smooth slider is also a security and energy issue — a door that won't latch is an easy entry point, and a bad seal leaks conditioned air all summer. We can add a stronger lock, fresh weatherstripping, and a security bar. For interior glass sliders and closets, ask about our pocket door and barn door work too.

Why DMV Patio Doors Wear Out
Montgomery County's four-season swings are hard on sliders: summer humidity swells the frame, winter cold contracts it, and the fine grit that blows onto decks and patios grinds into the bottom track and chews up the rollers. Most of the "broken" patio doors we see just need new rollers and a cleaned, capped track — a couple-hundred-dollar fix, not a couple-thousand-dollar replacement.
We'll always tell you when a repair makes sense versus when the frame or glass seals are too far gone to bother. If you've got a 1980s aluminum-frame slider that fogs up between the panes and ices over in January, replacement with a modern insulated unit usually pays for itself in comfort and energy savings — and we'll quote both paths honestly.
