How to Identify the Right Replacement Parts for Your Windows and Doors


When it comes to keeping your home secure, energy-efficient, and visually appealing, having properly functioning windows and doors is essential. Over time, parts like handles, hinges, locks, and rollers can wear out or break. But identifying the right replacement part can be overwhelming—especially with so many different brands, sizes, and models on the market.

Here’s a step-by-step guide to help you identify and find the correct window or door replacement parts with confidence.


1. Start by Identifying the Brand and Model

Most windows and doors have a small label or etched mark indicating the manufacturer. Common locations for these labels include:

  • The edge of the sash or frame
  • Inside the track
  • On the locking mechanism

If you can find the brand and model number, it becomes much easier to search for the right parts—either online or through a local supplier.


2. Take Accurate Measurements

If there’s no visible label or it’s unreadable, you’ll need to rely on measurements. Remove the broken part if possible and measure:

  • Length
  • Width
  • Depth
  • Hole spacing (especially for handles and locks)

Use a digital caliper or ruler for accuracy. Even a few millimeters can make the difference between a proper fit and a frustrating mismatch.


3. Take Clear Photos of the Part

Photographs are incredibly helpful—especially if you plan to ask for assistance from a professional or share images with a supplier. Be sure to take:

  • Close-up shots from multiple angles
  • A photo showing the part installed (if applicable)
  • A photo of the full window or door

Lighting matters—use natural light or a flashlight to avoid shadows that hide details.


4. Compare with Online Catalogs or Visit a Parts Specialist

Many suppliers—including Alex Windows & Doors Parts—have online catalogs where you can compare photos and specs. If you’re unsure, visiting a physical parts center or contacting a customer service team can save time and prevent costly mistakes.

Pro tip: Bring the part with you if you’re visiting in person—it makes it much easier for staff to find an exact match.


5. Check the Material and Finish

To maintain the look and functionality of your window or door, choose parts with matching materials and finishes. For example:

  • Brushed nickel vs chrome
  • White plastic vs off-white
  • Stainless steel vs aluminum

It’s especially important for visible hardware like handles and hinges.


6. Ask About Compatibility

Even if two parts look identical, they may not be compatible. Factors like screw placement, spring tension, or lock mechanisms can vary. When in doubt, ask a specialist before ordering.

Replacing a worn or broken window or door part doesn’t have to be stressful. With a bit of attention to detail—and the right guidance—you can restore your window or door’s performance quickly and affordably.
