Window Hardware Repair: 9 Genius Fixes the Pros Don’t Want You to Know

Hey there! My name is Jordan Atkinson, and I’m the founder of Westlake Window Glass here in Utah. I started this company back in 2017 after helping a neighbor fix a window when no one else would. Since then, I've helped hundreds of homeowners with window issues, and I’ve picked up a lot of handy tricks along the way.

Today, I want to share 9 genius fixes I’ve personally used for window hardware repair. These are the same tips I use every day in the field. Some are super simple. Some are a little more advanced. But they all work – and they’ll save you time, money, and a whole lot of frustration.

Let’s dive right in!

‍

1. Stuck Window? Use a Silicone Spray

If your window feels stuck or tough to open, don’t force it. That can cause even more damage. The first thing I always do is grab a can of silicone spray lubricant.

Here’s what to do:

• Open the window as far as it will go
  
  
• Spray a light coat into the track or on the metal arms (for crank windows)
  
  
• Open and close the window a few times to spread it evenly
  
  

Avoid WD-40 for this. It attracts dust and makes things worse over time. Silicone spray dries clean and keeps parts moving smoothly.

2. Crank Handle Spins But Window Doesn’t Move? Check the Operator Gear

Casement and awning windows use crank systems, and the small gear inside the operator can strip over time. If you hear clicking or the handle just spins, the gear is likely worn out.

You can fix this by replacing the window operator. It usually takes just 20-30 minutes with a screwdriver and a little patience. If you're handy, it's a great DIY project.

I recommend taking the old operator to the hardware store so you get the exact match.

3. Loose Window Locks? Tighten or Replace the Keeper

Window won’t stay locked? That could be a misaligned or loose keeper (the part the lock grabs onto).

Steps to fix:

1. Unscrew the keeper
   
   
2. Realign it so the lock clicks tight
   
   
3. Screw it back in
   
   

If the screw holes are stripped, use slightly longer screws or fill the holes with toothpicks and wood glue before reinstalling.

4. Window Sash Falling Down? Replace the Balance System

If you have a double-hung window and the sash won’t stay up, the balance system is likely broken.

There are two main types:

• Spiral balances (older homes)
  
  
• Channel or block-and-tackle balances (newer homes)
  
  

This is one fix where you really want the right part. Measure your window carefully, or better yet, remove the old balance and bring it with you when buying the replacement.

I’ve done this repair many times. Once you do it once, it’s easier than it looks.

‍

5. Drafty Window? Replace the Weatherstripping

Air sneaking through your closed window? Check the weatherstripping. It gets dry, cracked, or loose with age.

You can buy rolls of foam, felt, or rubber weatherstripping and cut it to size. Stick-on types are super easy to install and work great for sliding and casement windows.

Pro tip: clean the surface before sticking it on. Rubbing alcohol works great.

‍

6. Wobbly Handles or Latches? Use Thread Locker

Window handles and latches get loose over time. Most people just tighten the screws, but they come loose again.

The real trick? Use a thread locker (like Loctite). Just a tiny drop on the screw threads before you tighten them. It keeps everything snug without damaging the window.

‍

7. Broken Window Lock? Replace It With a Universal One

If you can’t find the original lock, don’t worry. Many hardware stores carry universal window locks that fit most aluminum and vinyl windows.

You’ll just need to match the hole spacing (usually 2-1/4 inches). This is a fast, cheap fix for security and peace of mind.

‍

8. Screen Keeps Falling Out? Bend the Tabs or Replace the Springs

Loose screens are super annoying. Check the small metal tabs or plastic clips that hold it in place.

Sometimes just bending them outward a bit can tighten the fit. If they’re broken or missing, you can buy spring-loaded clips for just a few bucks. Easy install.

‍

9. Can’t Find the Right Part? Use a Window Hardware Identification Site

There are so many types of window parts that even pros like me sometimes need help. When I can’t find a match, I use websites like swisco.com or prime-line.net.

Just upload a photo of your hardware and add measurements. These sites will help you identify and order the exact part you need.

Frequently Asked Questions (FAQ)

‍

1. How do I know if my window hardware needs to be replaced or just cleaned?

If your window sticks, rattles, or won’t lock properly, try cleaning and lubricating first. If that doesn’t help, the hardware likely needs replacing.

‍

2. Can I replace window hardware myself, or do I need a professional?

Many repairs are DIY-friendly if you have basic tools. For more complex issues (like balance systems or cracked glass), calling a pro is best.

‍

3. What’s the most common reason windows stop working properly?

Usually it’s dirt in the tracks, worn-out balances, or broken locks. These are all repairable without replacing the whole window.
