Restore Smooth Operation and Security at Home

Sliding glass door repair services for homeowners in Rockville and the DMV area.

When your sliding glass door starts dragging across the track, refusing to latch, or letting in drafts, it is more than an inconvenience. You are losing energy, compromising security, and risking further damage to the door frame and rollers. In Rockville and the DMV area, where many homes have sliding doors leading to patios, decks, or balconies, these issues are common in older installations and doors that have been exposed to weather, dirt, and frequent use over the years.


Potomac Glass Repair handles sliding glass door repairs throughout Rockville and the surrounding DMV area. We address cracked or shattered glass, worn rollers, misaligned tracks, and damaged locking mechanisms. Depending on the condition of your door, we may replace the glass, adjust the rollers, clean and realign the track, or install new hardware to restore smooth operation. The goal is to bring the door back to working condition without forcing a full replacement unless the frame itself is compromised.


If your sliding glass door in Rockville or a surrounding area is not functioning properly, contact Potomac Glass Repair to schedule a repair evaluation.

How Repair Restores Daily Function and Safety

We begin by inspecting the door, frame, track, and hardware to identify the root cause of the problem. In DMV area homes, we often find that dirt and debris have built up in the track, rollers have worn down from years of use, or the door has shifted out of alignment due to settling. If the glass is cracked or broken, we measure and order a replacement panel and remove the damaged glass safely before installing the new one.


Once the repair is complete, the door slides smoothly again without sticking or scraping. The latch engages securely, and the seal around the door prevents drafts and moisture from entering your home. You also regain peace of mind knowing the door can be locked properly, which is especially important if the sliding door is your main access point to a backyard or balcony.


We use tempered safety glass for all door panel replacements, and we install commercial-grade rollers and hardware designed for residential sliding door systems. This service does not include frame replacement, structural repairs, or repainting. If the door frame is rotted, warped, or no longer square, we will let you know so you can plan for a full door replacement if needed.

Homeowners in Rockville and throughout the DMV area who call about sliding glass door repair usually want to know whether their door can be fixed, how long the repair will take, and what might have caused the problem. Here are the questions we hear most often.

You Are Not Alone in Asking These

What are the most common sliding glass door problems?
The most common issues are cracked glass, worn rollers, misaligned tracks, and broken locks. Each of these can usually be repaired without replacing the entire door, depending on the frame condition.
How do I know if my sliding glass door needs repair or replacement?
If the glass is damaged or the door is not sliding smoothly, repair is usually the right choice. If the frame is rotted, warped, or structurally compromised, replacement is the better long-term solution.
Why is my sliding glass door so hard to open?
Difficulty sliding usually means the rollers are worn, the track is dirty or damaged, or the door has shifted out of alignment. We clean the track, replace worn rollers, and adjust the door to restore smooth operation.
How long does a sliding glass door repair take?

Most repairs in Rockville and surrounding areas take a few hours once we have the parts on hand. Glass replacement may require ordering a custom panel, which adds a few days to the timeline before installation.

Will repairing my sliding door improve energy efficiency?
Yes, especially if the door was letting in drafts due to a broken seal, misalignment, or cracked glass. A properly functioning door with intact weatherstripping reduces air leakage and helps maintain indoor temperatures.
