Window Repair Specialists -- DMV Area

Window
Won't Open?

A window that will not open, close, or lock properly is a safety hazard, a fire code violation, and an everyday frustration. We diagnose and fix stuck windows, broken mechanisms, and painted-shut frames.

Window Mechanism Repair Services

From painted-shut windows to stripped crank operators, we fix every type of window mechanism problem.

Painted-Shut Window Repair

Very Common

Years of paint buildup seals windows shut. We carefully break the paint seal, clean the channels, and restore smooth operation without damaging the finish or frame.

Balance and Spring Replacement

Most Common Fix

Double-hung windows rely on balance mechanisms (spiral, block and tackle, or channel) to stay open. When balances fail, the window slams shut or will not stay up. We replace all types.

Crank and Operator Repair

Casement and awning windows use crank operators that wear out, strip, or seize over time. We replace worm gears, operator arms, and crank handles for smooth cranking operation.

Lock and Latch Repair

Broken cam locks, sash locks, and keeper latches prevent windows from closing securely. We repair or replace locking hardware to restore proper security and weathertight seals.

Frame and Sash Repair

Warped, swollen, or rotted window frames prevent smooth operation. We repair wood frames, adjust vinyl sashes, and realign aluminum windows to restore proper function.

Weatherstripping Replacement

Worn weatherstripping causes windows to stick, bind, or not seal properly. We replace bulb seals, V-strips, and compression weatherstripping for all window types.

Fire Safety Warning

Building codes require at least one egress window in every bedroom that can be opened fully for emergency escape. A window that will not open in a bedroom is a serious fire safety violation. Landlords have a legal obligation to maintain operable egress windows. If you are a renter, notify your landlord in writing and document the issue.

FAQ

Stuck Window Questions

Why does my double-hung window slam shut when I try to open it?
The window balance has failed. Double-hung windows use a counterbalance mechanism (spiral, block-and-tackle, or channel balance) that supports the sash weight. When it fails, gravity pulls the window shut. Balance replacement is a straightforward repair we complete in 30-60 minutes per window.
Is a window that will not open a fire code violation?
Yes, in most cases. Building codes in Virginia, Maryland, and DC require egress windows in bedrooms to be operable. A stuck window in a bedroom is both a safety hazard and a code violation. Landlords and property managers have legal obligations to maintain operable egress windows.
Can you fix a painted-shut window without repainting?
In most cases, yes. We use specialized tools to break the paint seal along the sash edges without damaging the surrounding paint. Some minor touch-up may be needed where the seal was broken, but we do not repaint entire frames.
My casement window crank spins but the window does not move. What is wrong?
The worm gear inside the operator has stripped. The crank handle turns, but the gear no longer engages the operator arm. This is a common failure on casement windows over 10 years old. We replace the entire operator assembly for a reliable fix.
How much does window mechanism repair cost?
Hardware repairs (balances, operators, locks) are typically a fraction of the cost of full window replacement. We provide free estimates and always recommend repair over replacement when the glass and frame are in good condition. Call (703) 679-7741 for a quote.
Should I try to force a stuck window open?
No. Forcing a stuck window risks breaking the glass, damaging the frame, or injuring yourself. If the window is painted shut, you risk cracking the paint across the entire wall. If the mechanism is broken, forcing it can cause additional damage. Let a professional assess it first.
