Windows play a vital role in home insulation, security, and aesthetics. However, over time, they can develop issues that may need immediate attention. Below, we answer some of the most frequently asked questions about window repairs, including common problems and quick solutions to help homeowners maintain their windows efficiently.

1. What are the most common window problems?

Windows are subject to wear and tear due to exposure to weather, temperature changes, and frequent use. Some of the most common issues include:

• Drafts and air leaks, often caused by deteriorating weather stripping or poor insulation, leading to increased energy bills.
• Condensation between panes, which indicates a broken seal allowing moisture to accumulate inside the glass layers.
• Difficulty opening or closing windows, due to swollen frames, dirt buildup, or damaged hardware.
• Cracked or broken glass, which compromises both security and insulation.
• Foggy or cloudy windows, typically caused by a failed double-pane seal.
• Damaged window screens, allowing insects and debris to enter the home.

2. How can I fix a drafty window?

A drafty window can significantly impact your home’s energy efficiency, making it essential to address the issue promptly. One of the simplest fixes involves applying weather stripping around the frame to seal any gaps. Caulking is another effective method to close cracks and prevent air leaks. For homeowners looking for a temporary solution during colder months, plastic window insulation film can provide an extra layer of protection. If the issue persists, inspecting and replacing worn-out window seals may be necessary to ensure proper insulation.

3. Why is my window stuck and how do I fix it?

Windows that won’t open or close properly can be both frustrating and hazardous. The first step is to check for paint buildup, as layers of paint can seal windows shut over time. Using a utility knife to break the seal can help free the window. Another common cause is debris accumulation in the tracks, which can be resolved by thoroughly cleaning the area. Lubricating the moving parts with silicone spray or wax can improve functionality. If moisture has caused wooden frames to swell, sanding and resealing the wood may be required to restore smooth operation.

4. What should I do if I see condensation inside my double-pane windows?

When condensation appears between double-pane windows, it signals a broken seal that allows moisture to seep in. While some professionals offer defogging services to remove trapped moisture and reseal the unit, this solution may not be permanent. In many cases, replacing the window seal is the best course of action. If the damage is extensive, a full glass replacement may be necessary to restore clarity and insulation. Homeowners should also consider investing in windows with improved sealing technology to prevent future issues.

5. Can I repair a cracked window, or should I replace it?

Small cracks in window glass may be temporarily patched using clear nail polish or epoxy, which can help prevent the crack from spreading. Glass repair kits are another option for addressing minor damage. However, these solutions are not permanent, and in cases where the crack is expanding or significantly weakens the window, replacement is the recommended approach. Replacing the glass ensures long-term durability and maintains the structural integrity of the window.

6. How do I replace a torn window screen?

When a window screen is damaged, it can be easily replaced with a few simple steps:

1. Remove the damaged screen from the frame.
2. Cut a replacement screen slightly larger than the frame.
3. Place the screen over the frame and secure it with a new spline.
4. Use a screen rolling tool to press the spline into the groove.
5. Trim excess screen material with a utility knife.

This process restores the screen’s functionality, keeping insects and debris outside while maintaining airflow.

7. How can I prevent window damage in the future?

Routine maintenance is key to extending the life of your windows and avoiding costly repairs. Regularly inspecting seals and weather stripping ensures that they remain intact, reducing air leaks. Lubricating tracks and hinges prevents sticking and improves ease of use. Cleaning windows and screens periodically helps remove dirt and debris that may cause damage over time. Additionally, avoiding forceful closing or slamming of windows reduces the risk of frame misalignment or glass breakage. Homeowners should also trim trees or branches near windows to prevent potential impact damage during storms or strong winds.

8. What are some ways to improve window energy efficiency?

Improving your window’s energy efficiency can lower utility costs and enhance indoor comfort. Installing energy-efficient windows, such as those with Low-E coatings or double-pane glass, significantly reduces heat loss. Window film is another option that helps regulate temperature by blocking excess heat and UV rays. Using blackout or thermal curtains adds an additional layer of insulation, especially during extreme weather conditions. Sealing any visible gaps or cracks with caulk or weather stripping prevents unwanted air exchange, ensuring better energy efficiency year-round.

9. When should I call a professional for window repairs?

While many minor window issues can be fixed with DIY solutions, certain problems require professional assistance. Extensive glass damage, such as large cracks or shattered panes, should be addressed by an expert to ensure safety and durability. Windows that refuse to open or close due to structural issues may need adjustments or replacements beyond basic repairs. Persistent fogging or condensation inside double-pane windows often requires professional sealing or full replacement. If drafts remain despite DIY sealing efforts, a professional evaluation can identify underlying issues. Additionally, warping, rotting, or other forms of structural damage may indicate the need for a full window replacement.

10. How much does window repair cost?

The cost of window repair varies depending on the severity of the damage and the type of repair needed. Here’s a general estimate of common window repair expenses:

• Minor repairs (weather stripping, caulking): $50 – $150
• Glass replacement: $150 – $500 per window
• Seal repair: $100 – $250 per window
• Frame restoration: $200 – $600

For homeowners requiring multiple window repairs, some professional services offer discounts based on the scope of work.
