Restore Safety and Seal Your View

Professional window repair and replacement services for homeowners in Rockville and the DMV area.

If you have a cracked or broken window in your home in Rockville, Bethesda, Arlington, or a surrounding area, you are dealing with more than a visible blemish. You are losing heat in winter, letting moisture seep into the frame, and leaving your home less secure. Whether the damage came from storm debris, age, or accidental impact, the longer you wait, the more the surrounding material deteriorates. In Rockville neighborhoods with older housing stock, failing window systems often compound quickly once glass integrity is compromised.


Potomac Glass Repair works with both single-pane and double-pane window glass to restore function and appearance. We assess the frame condition, measure the opening, and install glass that matches the existing system. If the frame itself is compromised or the seal has failed in a double-pane unit, we explain what can be saved and what needs replacement. The goal is to stop air leakage, block drafts, and return the window to full operation without forcing you into a full remodel.


If you are ready to address broken or underperforming windows in the Rockville and DMV area, reach out to Potomac Glass Repair to schedule an evaluation.

What Changes After Your Window Is Repaired?

We begin by removing the damaged glass and cleaning out any broken shards, old glazing compound, or compromised seals. In Rockville and throughout the DMV, where temperature swings between seasons are significant, we pay close attention to how the replacement glass sits in the frame and whether the existing weatherstripping still functions. If it does not, we replace it during the same visit to prevent future drafts.


Once the new glass is installed, you will notice an immediate difference in how the room feels. Cold spots near the window disappear, outside noise decreases, and condensation between panes is eliminated if the unit was previously fogged. The window operates smoothly again, and the view returns to full clarity without distortion or cracks obstructing your sightline.


We also inspect the surrounding trim and sill for water damage or rot that may have developed while the window was compromised. If we find structural issues, we let you know what needs attention to prevent recurrence. This service does not include carpentry or siding work, but we identify those needs so you can plan accordingly before the next weather event arrives.

Homeowners in Rockville and the surrounding areas often ask about timing, glass options, and whether repair makes sense compared to full window replacement. These are the most common questions we hear before starting work.

You Probably Have a Few Questions

How do I know if my window needs repair or full replacement?
If the glass is damaged but the frame is solid, square, and free of rot, repair is usually the right choice. We assess the frame during the visit and let you know if replacement is the better long-term option.
What is the difference between single-pane and double-pane window repair?
Single-pane windows involve one sheet of glass and are faster to replace. Double-pane units are sealed with insulating gas between two layers, so if that seal fails, the entire unit needs replacement to restore insulation and eliminate fogging.
How long does a typical window repair take?
Most single-window repairs in Rockville take one to two hours once the glass is cut and ready. Double-pane units may require ordering a custom sealed unit, which adds a few days to the timeline before installation.
Why should I repair a window quickly instead of waiting?
Broken or cracked glass allows moisture into the frame and sill, which leads to wood rot, mold growth, and higher heating or cooling costs. Prompt repair prevents these secondary issues from spreading.
