1. Energy Efficiency: Damaged windows can lead to air leaks, which can increase your heating and cooling costs. Repairing windows can help maintain a consistent indoor temperature and reduce energy bills.

Steps to Replace Broken Glass:

1. Safety First: Wear gloves and safety goggles to protect yourself from sharp edges.

3. Clean the Frame: Use a wire brush to remove any remaining putty or debris from the frame.
4. Install New Glass: Place the new glass into the frame, ensuring it fits snugly. Use glazing points to hold it in place.
5. Apply New Putty: Apply a thin layer of glazing putty around the edges of the glass to seal it. Smooth the putty with a putty knife.
6. Paint the Putty: Allow the putty to dry according to the manufacturer’s instructions, then paint it to match the frame.

2. Loose or Sticking Sashes

Loose or sticking sashes can be a frustrating problem, often caused by misalignment or worn-out hardware.

Steps to Fix a Sticking Sash:

1. Lubricate the Tracks: Use a silicone spray or wax to lubricate the tracks of the window. This can help reduce friction and make the sash slide more smoothly.

3. Drafty Windows

Drafty windows can significantly impact your home’s energy efficiency. Here’s how to address this issue:

1. Identify the Source of the Draft: Use a lit candle or a smoke stick to identify where the air is leaking. Common culprits include gaps around the sash, damaged weatherstripping, and loose frames.
2. Replace Weatherstripping: Remove the old weatherstripping and install new strips. There are various types available, including foam, rubber, and vinyl.

4. Install Window Insulation Film: For a temporary solution, consider using window insulation film. This can help reduce drafts during colder months.

4. Rotted or Damaged Wood Frames

Wooden window frames can deteriorate over time due to moisture exposure, leading to rot and damage.

Steps to Repair Wood Frames:

1. Assess the Damage: Determine the extent of the damage. If the frame is severely rotted, it may need to be replaced.
2. Remove Rotted Wood: Use a chisel or a wood-rot repair kit to remove the rotted wood. Clean the area thoroughly to ensure it is free of debris.
3. Apply Wood Hardener: Apply a wood hardener to the damaged area to stabilize the remaining wood.

5. Leaky Windows

Leaky windows can cause water damage and mold growth. Here’s how to stop the leaks:

1. Identify the Leak: Determine where the water is entering. Common entry points include the sill, the joints between the frame and the wall, and around the sash.
2. Apply Caulk: Use a high-quality, exterior-grade caulk to seal any gaps or cracks. Apply a thin, continuous bead of caulk and smooth it with a caulk finishing tool.
3. Install Flashing: If the leak is coming from the sill, consider installing a new flashing. This can help direct water away from the window and prevent future leaks.
4. Replace Seals: If the leak is around the sash, replace the seals or gaskets. These can wear out over time and need to be replaced to maintain a watertight seal.

FAQs About Window Repair

Q: How can I tell if my window needs to be replaced rather than repaired?

A: It’s a good idea to check and maintain your windows at least once a year. Look for signs of wear and tear, check the seals, and lubricate the hardware as needed.

Q: Can I repair a window myself if it’s stuck?

A: Yes, you can often fix a stuck window yourself by lubricating the tracks, adjusting the hardware, or realigning the sash. However, if the window is very old or if the problem persists, a professional may be needed.
