Our Window Sash Repair Services

We address common issues specific to single-hung and double-hung window sashes with precision. Our repairs aim to restore smooth operation, enhance security, and improve energy efficiency. We also offer sash replacement options tailored to your window type and condition.

Single-Hung Window Sash Repairs

Single-hung windows have a fixed upper sash with a movable lower sash. We repair issues like stuck or misaligned sashes, damaged or worn-out cords, and broken locking mechanisms. Proper adjustment and lubrication of rollers and tracks are part of our process to ensure easy movement.



Our focus includes sealing gaps around the sash to stop drafts and prevent water infiltration. We inspect for rot or warping in the lower sash and recommend repair or replacement if necessary. Each repair aims to improve function and extend the window’s lifespan.

Double-Hung Window Sash Repairs

Double-hung windows have two operable sashes that slide vertically. We handle repairs on both sashes, focusing on counterbalance systems including weights, pulleys, and springs that facilitate smooth raising and lowering.



We fix sash alignment problems that cause sticking or rattling. Lock and latch repairs ensure security. Weatherstripping replacement is common to improve insulation. Our goal is to restore full functionality and maintain ease of operation on both sashes.

Sash Replacement Solutions

When repairs are insufficient, we provide sash replacement services using materials that match your window’s original style and structure. We offer options in wood, vinyl, or aluminum sashes depending on durability and maintenance preferences.



Replacement includes precise measurements and professional installation to ensure proper fit and operation. We ensure weatherproofing and energy efficiency with every replacement, helping reduce air leaks and moisture issues. Our solutions protect your home’s comfort and value.

Benefits of Professional Sash Repair

Proper sash repair provides practical advantages that directly affect your home's comfort, security, and window durability. Addressing sash issues promptly ensures better insulation, safer windows, and longer-lasting hardware.

Enhanced Energy Efficiency


Damaged or warped sashes create gaps that allow air to flow freely in and out. This leads to increased heating and cooling costs as your HVAC system works harder to maintain the desired temperature.


By restoring a tight seal around the window sash, professional repairs reduce drafts and heat loss. This can lead to noticeable reductions in your energy bills. Additionally, repaired sashes improve insulation against outside noise and weather.


Improved Home Security


A poorly functioning window sash can be an easy entry point for intruders. Loose or damaged sashes are more vulnerable to forced opening or break-ins.


We make sure the repair reinforces locking mechanisms and ensures sashes close securely. This enhances the window’s resistance to external pressure or

tampering.


Extended Lifespan of Windows


Regular sash repairs prevent minor issues from becoming major problems. Left unattended, damaged sashes can lead to frame warping, glass breakage, or more costly window replacements.


We replace worn hardware parts and adjust sash balance to maintain smooth operation over time. Properly repaired windows experience less wear and tear because they open and close correctly.

Frequently Asked Questions (FAQs) About Single-Hung and Double-Hung Window Sash Repairs


  • How much does window sash repair cost compared to replacement?

    Window sash repair typically costs 40-60% less than full window replacement. Our sash repairs usually range from $150-400 per window, while complete window replacement can cost $300-800 or more per window. The exact savings depend on the extent of damage and window type, but repair is almost always the more economical choice when the frame and glass are in good condition.

  • Can broken window sashes be repaired or do they need replacement?

    Most broken window sashes can be successfully repaired rather than replaced. We can fix common issues like broken sash cords, damaged balance springs, warped frames, and stuck mechanisms. The only time we recommend full replacement is when the sash has extensive rot, severe structural damage, or when repair costs would exceed 70% of replacement cost.

  • Do I need a professional to repair my window sash or can I DIY?

    While minor issues like cleaning tracks or lubricating mechanisms can be DIY projects, most sash repairs require professional expertise. Broken sash cords, balance spring replacement, and frame adjustments involve specialized tools and techniques that can cause further damage if done incorrectly. We recommend professional repair to ensure proper function, maintain warranties, and avoid safety risks associated with improperly secured window sashes.
