Home Window Repair in Virginia, Maryland & Washington, DC

Advanced Window & Glass Repair is a family-owned residential window repair company serving homeowners across Maryland, Virginia, and Washington, DC since 1999. With offices in Woodbridge, Arlington, Silver Spring, and Burke, our glaziers provide local service backed by years of hands-on experience. We are not a national franchise. Our own team handles each repair from inspection through completion.

Most window problems start with a single failed component. A worn balance, broken lock, failed insulated glass seal, or cracked pane can make a window seem beyond repair. Our glaziers find the source of the problem and repair the affected part whenever possible. This keeps your existing frame, trim, and interior finishes intact while restoring normal operation.

We provide clear recommendations before any work begins. Some windows can be restored, while others have damage that makes replacement more practical. Our team explains the difference without pushing you toward a new window. As a licensed and insured glass company, we stand behind our workmanship on every repair and help DMV homeowners make informed repair decisions.

A properly working window sash should move smoothly with light pressure. Paint buildup, swollen wood, worn balances, and damaged weatherstripping can make it stick or rattle. Our glaziers release stuck sashes, adjust loose movement, and replace worn seals.

Many DMV homes have wooden sashes, while newer properties use vinyl tilt-in designs. Our glass experts repair both types on site. Our team checks sash parts before work begins, then provides a clear diagnosis and flat-rate price first.

• Stuck and painted-shut sash release
• Loose sash adjustment for a tighter seal
• Worn weatherstripping replacement
• Wood and vinyl sash repair
• Glazing putty and parting bead repair

A window that slams shut or will not stay open often has a failed balance system. Double-hung and single-hung windows rely on several balance designs. Our glaziers identify the system and replace only the damaged parts needed.

Most balance and spring repairs can be completed in one visit. Our glass experts arrive prepared with suitable replacement parts. Our team restores sash support without the cost of replacing an otherwise repairable window.For the balance types we repair and the parts involved,see our window balances and springs repair page.

Each window style develops different operating problems over time. Double-hung windows can lose balance support, while single-hung units develop worn tracks. Casement windows may have stripped operators or loose hinges. Our glaziers repair these components.

Our team repairs major window styles found across Northern Virginia, Maryland, and Washington, DC. Our glass experts also work on older windows that need careful restoration. We first confirm the repair makes sense for your specific unit.

Your window frame supports the glass, sash, and weather seal. Cracks, rot, and failed caulking can let water, air, and insects inside. Our glaziers inspect the damage, repair affected sections, and seal exposed gaps to help protect the opening.

Not every frame issue calls for full window replacement. Our glass experts can address localized wood rot, cracked vinyl, and failed exterior caulking. Our team explains the condition clearly and tells you when replacement is necessary.

• Cracked vinyl and aluminum frame repair
• Rotted wood frame section replacement
• Exterior caulking and resealing
• Water leak detection around window frames
• Full frame inspection before any repair

A window that will not lock can leave your home less secure. Broken sash locks, worn keepers, and loose hinges can also allow drafts and outside noise through. Our glaziers repair or replace damaged hardware and match existing parts when possible.

Our glass experts use quality replacement parts from manufacturers such as Truth Hardware, Amesbury, and Caldwell. Our team matches the hardware to your window for proper operation, secure closing, and dependable performance across the DMV.

Transom windows bring natural light above doors and larger windows. Because they sit high, damage often goes unnoticed until a leak appears. Cracked glass, failed seals, and loose frames are the most common transom problems. Our technicians access these elevated openings safely and repair them carefully. Your transom looks clean and seals properly again.

We repair both clear and decorative transom glass. Many entry door transoms contain tempered or insulated glass units. Our team matches the glass type, shape, and thickness to your original design. We complete most transom repairs without disturbing the door, frame, or surrounding trim.

• Cracked transom glass replacement
• Entry door transom repair
• Decorative transom glass matching
• Transom seal and frame repair

Your property stays protected until we install the new glass.
