Single-Hung and Double-Hung Window Sash Repairs
Single-hung and double-hung window sash repairs are essential for maintaining proper window operation, energy efficiency, and home comfort. Over time, window sashes can develop various problems including broken sash cords, failed balance systems, warped components, and operational difficulties that prevent smooth opening and closing. These issues not only affect convenience but can also compromise security, ventilation, and energy performance.
Common sash problems include windows that won't stay open, stick when operating, fall unexpectedly, or fail to seal properly when closed. These issues often stem from worn balance mechanisms, damaged weatherstripping, swollen wood components, or broken hardware that requires professional attention to restore full functionality.

Our Sash Repair Service Overview
We focus on the specific characteristics of single-hung and double-hung window sashes and the common problems that affect their function. Understanding these points helps us provide precise repairs that restore performance and appearance.
Window Sash Types
Single-hung windows have a fixed upper sash and a movable lower sash that slides vertically. This design is simpler, usually found in older or more traditional homes. Their operation relies on smooth movement of the bottom sash only.
Double-hung windows allow both the upper and lower sashes to move vertically. This design offers greater ventilation control and easier cleaning access. Both sashes typically have counterweights or spring balances, adding complexity to their maintenance and repair.
Knowing these differences guides our repair approach and ensures that each sash operates correctly, sealing tightly to improve energy efficiency and security.
Common Issues With Sashes
Sashes often face problems like difficulty sliding, broken locks, or damaged cords and balances. Over time, wood sashes can warp or rot, while vinyl or aluminum frames may crack or dent. These issues affect window usability and insulation.
Another frequent problem is air or water leakage due to failed weather stripping or gaps caused by sash misalignment.
Loose or broken hardware can prevent sashes from locking securely, compromising safety and energy performance.
We identify and address these specific defects to restore smooth operation and proper sealing, extending the life of your windows.
Our Repair Process
We focus on a thorough evaluation and precise restoration to ensure your window sashes function smoothly and safely. Our approach uses high-quality materials and ends with careful testing and cleanup for durable results.
1. Initial Inspection
We begin by examining each sash carefully to identify issues like warping, sticking, or broken components. Our technicians check the entire frame, hardware, and glazing to spot hidden problems that might affect performance.
This step includes measuring sash alignment and assessing weather stripping condition. We document all findings and discuss repair options with you, ensuring transparency before any work starts.
2. Precision Sash Restoration
Our team applies targeted methods tailored to the sash type and damage extent. We repair or replace damaged rails, stiles, and muntins using woodworking techniques that maintain the sash’s original integrity.
For double-hung windows, we ensure the balance system is calibrated correctly to prevent future operational issues. We also restore proper glazing and sealant to improve insulation and security.
3. Quality Materials and Parts
We use durable, industry-standard components chosen for compatibility with your window make and model. This includes weather-resistant wood, corrosion-proof hardware, and energy-efficient glass options where needed.
Our parts suppliers are vetted to guarantee longevity. Whenever possible, we match replacement materials to your existing sashes for a seamless appearance and performance.
4. Final Testing
Once repairs are complete, we perform functional tests on each sash to confirm smooth operation and secure locking. We look for even movement, effective sealing, and balanced counterweights.
Our team then cleans the work area thoroughly. We remove debris, old materials, and any residue, leaving your windows ready for immediate use without additional effort on your part.

Frequently Asked Questions About Single-Hung and Double-Hung Window Sash Repairs
How much does window sash repair cost?
Window sash repair costs typically range from $100 to $300 per window, depending on the type of repair needed and window complexity. Simple adjustments or weatherstripping replacement are on the lower end, while sash cord replacement or balance system repairs cost more. Double-hung windows with weight and pulley systems may require more extensive work. We provide free estimates to assess your specific repair needs.
Can broken window sash cords be replaced?
Yes, broken window sash cords can be replaced on both single-hung and double-hung windows. The process involves accessing the sash weight cavity, removing the broken cord, and installing new sash cord or modern alternatives like chains or springs. We can also upgrade older cord systems to more reliable balance mechanisms during the repair process for improved longevity.
Is it worth repairing window sashes or replacing the whole window?
Repairing window sashes is often worthwhile when the window frame and glass are in good condition. Sash repairs can restore full functionality at a fraction of replacement cost. However, if multiple components are failing, the frame is damaged, or energy efficiency is poor, full window replacement may be more cost-effective long-term.
Can you fix a window sash that won't stay up?
Yes, we can fix sashes that won't stay up by addressing the underlying cause. This typically involves replacing broken sash cords, adjusting or replacing balance springs, or repairing sash weights and pulleys. We diagnose the specific issue with your window's balance system and restore proper operation so the sash stays in position.
How do you repair a stuck window sash?
Stuck window sashes are repaired by identifying and addressing the cause, which could be paint buildup, swollen wood, damaged tracks, or debris accumulation. We carefully free the sash, clean and lubricate tracks, plane or sand swollen areas, and ensure proper alignment. Sometimes weatherstripping adjustment or replacement is needed to restore smooth operation.
