This simple repair can prevent deficiencies during a home inspection.
Make sure the spring doesn't come off while installing the latch.

Common Mistakes to Avoid

1. Incorrect Latch Placement

Reason: Installing the latch too high or too low prevents the window from tilting properly or closing securely.

Solution: Carefully align the latch with the corresponding receiver on the window frame before tightening.

2. Stripped Screws or Damaged Holes

Reason: Using the wrong size screws or forcing them can damage the window frame, leading to a loose latch.

Solution: Use the correct size screws and pre-drill pilot holes if necessary to prevent stripping.

3. Ignoring Window Alignment

Reason: A misaligned window will not close correctly even with a properly installed latch, creating gaps and security concerns.

Solution: Ensure the window frame is properly aligned and secured before installing or adjusting the latch.

FAQs

What type of tools do I need to replace a window tilt latch?

You'll primarily need a screwdriver (likely a Phillips head), possibly a small flathead screwdriver for prying, and potentially a replacement latch. Sometimes a pair of pliers can be helpful for stubborn screws.

My window latch is broken beyond repair. Can I just buy any replacement latch?

Not necessarily. While many latches are similar, it's best to measure your existing latch and find a replacement with the same dimensions, or take the old latch to a hardware store for assistance in finding a compatible match. Pay attention to the type of screw attachment and the shape of the latch itself.
