Here are some common problems with double hung windows and tips on how to fix them to keep your windows in optimal condition.

1. Difficulty Opening or Closing

One of the most common issues with double hung windows is difficulty in opening or closing the sashes. This can be caused by dirt, dust, or debris accumulated in the window tracks or on the sashes themselves. To fix this, start by cleaning the tracks thoroughly using a soft brush or cloth to remove any debris. You can also use a vacuum cleaner to ensure all dirt is removed from the tracks. Lubricate the tracks and pulleys with a silicone-based lubricant to facilitate smooth movement of the sashes.

2. Drafts and Air Leaks

Drafts around double hung windows can lead to energy loss and discomfort, especially during extreme weather conditions in Ashburn. Inspect the weatherstripping around the edges of the window frames regularly. If you notice any gaps or signs of wear in the weatherstripping, replace it promptly to restore the seal and prevent air leaks. This simple fix can improve energy efficiency and comfort indoors.

3. Condensation Between Glass Panes

Condensation between the glass panes of double hung windows can occur when the seal between the panes fails, allowing moisture to accumulate inside. This not only obstructs your view but also indicates a potential issue with the window’s insulation. If you notice condensation, the best solution is to replace the affected window glass or consider upgrading to newer, more energy-efficient windows that feature improved insulation and seals.

4. Rotting or Decaying Wood

Wooden window frames, if not properly maintained, can be susceptible to rotting or decaying, especially in humid climates like Ashburn. Inspect the window frames regularly for any signs of moisture damage, such as soft or discolored wood. If you discover rotting wood, it’s essential to address the issue promptly by repairing or replacing the affected parts of the frame. Consider using wood preservatives or opting for alternative materials like vinyl for future window replacements.

5. Foggy or Cloudy Glass

Foggy or cloudy glass in double hung windows is often caused by a broken seal or moisture infiltration between the window panes. While this can affect visibility and insulation, it typically indicates that the window’s thermal performance has been compromised. In such cases, it’s advisable to consult a professional window contractor like Ameritech Construction at (703) 783-2676 for a thorough inspection and assessment. They can recommend appropriate solutions, such as replacing the affected glass or upgrading to newer, more efficient windows.
