Window Sill, Frame and Sash Repair
Restoration and Repair: Wooden Window Sills, Frames, and Sashes
Wood and steel windows are designed to last for decades, unlike modern replacement windows made to fail quickly. Older windows can be repaired and maintained relatively easily, unlike complex modern windows. Properly restored wooden windows with adequate sealing can meet or exceed energy efficiency standards while being more eco-friendly than new non-renewable material windows.
The wood window repair process involves removing sashes, restoring jambs, replacing sash ropes/cords, deglazing, removing paint, repairing damaged wood, reglazing, and reinstalling sashes. Restoring original windows is often preferred and can cost similarly to high-quality replacements while preserving architectural character. The restored windows become more energy-efficient with new hardware and sash cords designed to last for years.

Common Causes of Damage
Wooden windows are sensitive to various environmental factors that can lead to damage over time. Here are some common causes:
- Climate and Weather Conditions: Fluctuations in temperature and humidity can cause wood to expand and contract, resulting in issues like cracks, mold growth, and peeling paint or stain.
- Harsh Sunlight: Prolonged exposure to direct sunlight can cause the wood to dry out and crack, compromising its structural integrity.
- High Humidity Areas: Regions with high humidity levels can lead to moisture buildup within the wood, potentially causing the loosening of caulking or sealants. This can create entry points for water, leading to further damage.
- Wet Climates: Areas with frequent rainfall or snowfall increase the risk of wood rot if the windows are not properly protected. Moisture can seep into the wood, creating an ideal environment for fungal growth and decay.
To mitigate these issues, it’s crucial to take preventive measures, such as:
- Proper Weatherproofing: Regularly inspect and maintain the caulking and sealants around the windows to prevent moisture intrusion.
- Adequate Ventilation: Ensure proper ventilation around the windows to prevent moisture buildup and promote air circulation.
- Regular Maintenance: Perform routine inspections and address any signs of damage promptly to prevent further deterioration.
By understanding the common causes of damage and implementing preventive measures, homeowners can extend the lifespan of their wooden windows and maintain their structural integrity and aesthetic appeal.
Assessment and Preparation
Before beginning any restoration or repair work on wooden windows, it’s crucial to assess the condition of the existing components and prepare the work area properly. Here are the key steps:
- Inspect the Window:
- Check for damage like cracks, peeling, or mildew growth and address any issues.
- Examine the general condition of the window – look for any rotten, loose, or broken parts, and ensure the casement fits properly in the frame.
- Prepare the Work Area:
- Remove the exterior shutters and trim pieces to access the window.
- Remove the upper and lower sash by taking out the stops and parting stops.
- Proper personal protective equipment (PPE) like respirators, coveralls, and goggles is essential when working with lead paint.
- Contain the work area thoroughly to prevent lead dust from spreading.
- Remove and Store Components:
- Remove the glass (if needed) – carefully remove the old putty and glazier’s points to take out the glass. Clean the glass and store it safely.
- Clean out old, hardened glazing putty from the sash.
- Safety Precautions:
- Use low-dust work techniques like chemical strippers and infrared paint removers instead of power tools.
- Remove flaky paint and putty, or completely strip the old paint back to the bare wood. This can be done using a heat gun, chemical stripper, or sanding. Safety gear is important.
By following these steps, you’ll be able to assess the condition of the window accurately and prepare the work area for the restoration or repair process, ensuring a safe and efficient workflow.

Maintenance and Prevention
Maintaining wooden windows requires a proactive approach to prevent damage and extend their lifespan. Here are some essential maintenance and prevention tips:
- Regular Cleaning:
- Remove loose dust and dirt using a soft, dry cloth.
- Wash the window frames using a mild detergent, warm water, and a soft cloth or sponge, avoiding soaking the frames.
- Clean the glass using a glass cleaner or a vinegar/water solution, wiping with a microfiber cloth or newspaper.
- Protective Measures:
- Windows facing south are more vulnerable to weathering and require more frequent maintenance.
- Avoid paints that fully block the sun but trap moisture, as this can promote decay.
- Install overhangs or awnings to protect exterior frames in wet climates.
- Use UV-protective films or coatings to filter out harmful UV rays and prevent fading or damage.
- Routine Inspections and Maintenance:
- Clean wood window frames every 6 months using a mild soap and water, avoiding excessive moisture.
- Use low-VOC finishes for interior frames.
- Apply high-quality paints or finishes designed for wood to enhance appearance and protect from the elements.
- Lubricate hinges, handles, and moving parts with a silicone-based lubricant to prevent friction-related wear.
- Check and replace worn or damaged weather-stripping (sealing) to maintain energy efficiency and prevent drafts.
- Use a dehumidifier to control indoor humidity and prevent condensation, mold, and mildew.
- Regularly inspect for signs of pest infestations like termites and address promptly.
- Wipe down the windows with a damp cloth or sponge to keep them clean, avoiding harsh chemicals that can damage the wood.
- Install weather-stripping (sealing) to prevent drafts.
- Lubricate any moving parts on the windows, like locks and hinges, to ensure they function properly and don’t wear out.
- Keep the windows dry by avoiding leaving them open in rainy or humid conditions, as moisture can damage the wood.
- Ensure proper ventilation to prevent moisture buildup.
Prompt repairs and maintenance can help wood windows last for many years. Seek professional maintenance services to ensure the longevity and beauty of your wood windows.
