You probably know these days, when you think you have everything under control, and suddenly everything begins to fall apart. Every avalanche starts with a small snowflake. So, even if a cracked window decides to test your DIY skills and nerves, we’ll be here to help. In this guide, we’ll share the latest and most effective tips for 2025 to repair window cracks.
(Sorry for the spoiler, but if the crack is too big, it’s time for a windows replacement!)
What Type of Window Glazing Do You Have?
First of all, you need to identify the window type you’re working with, as different types require specific repair methods. Here are a few common types of windows you may encounter:
Single-glazed windows
As it follows from the title, these windows have only one glass pane. Single-glazed windows are the most basic type (especially in the older parts of Toronto), so it will be easier to find the necessary tools to repair them.
Double-glazed windows
Insulated glass units (IGUs) have two or more glass panes which are separated by a spacer and sealed together. Even if only one pane is cracked, we recommend the entire unit replacement. Double-glazed windows usually have special gas between the glass panes that starts leaking through the cracks. It isn’t harmful, but if you want to achieve optimal insulation and energy efficiency, you’ll have to replace the whole window.
Other window types
There are various specialty windows, such as laminated, tempered, and stained-glass. They have unique characteristics and composition. Consequently, these windows may require specific repair techniques or professional assistance. Always consult with the HTR windows replacement company to avoid costly repairs in the future. We will help you determine the best way to fix a window crack or perform window installation for you.
How Bad Is the Damage?
The next step is to determine the type of crack you have. It will make it easier to calculate the amount of sealer you need. Common crack types are:
- If the crack is hairline-thin and barely visible, you might be able to repair it yourself;
- When the crack extends through part of the glass, it’s best to consult our professional for guidance;
- If your window is shattered or completely broken, secure the area and call HTR for window replacement.
Once you determine the type of window you’re dealing with and the type of crack, it’s time to look for tools and materials to repair it. But, please, don’t overestimate your skills. We are sure that you are the best at everything, yet sometimes hiring real professionals is the best way to save time and nerves in the future. HTR Windows and Doors specialists have the expertise to fix, maintain or replace your windows efficiently and at an affordable price.
Which Tools and Materials Will You Need?
To fix your cracked window and get the job done right, you’ll definitely need safety gear, such as gloves, glasses, and a dust mask. Other essentials include, but are not limited to:
- Tape measure
- Putty knife
- Glass cleaner
- An epoxy mixture
- Clear tape
If you can’t find an epoxy mixture, you can replace it with resin, special sealer, nail polish or superglue.
Temporary Fixes for Small Cracks
If you’re dealing with a small crack and need a quick fix, there are two routes you can take until you can repair or replace the window. You can apply a thin layer of clear nail polish along the crack to prevent it from spreading further and strengthen it with clear tape.
Or, if you don’t have nail polish, you can use superglue. Spread it on the crack and let it dry. Remember, these solutions are temporary and won’t provide a permanent fix. Be sure to follow up with proper repairs to avoid further damage.
Cracked Window Repair: Steps to Take
Here’s a step-by-step guide to show you how the actual repair process works.
Step 1: Clean the crack
Put on your safety gear and thoroughly clean the cracked area first. Use a special glass cleaner to achieve better results. You should also be cautious not to injure yourself with any loose shards or debris.
Step 2: Apply clear tape
If you’re dealing with a single-glazed window, add clear tape to both glass sides to prevent the crack from spreading during the repair.
Step 3: Prepare the epoxy or resin
Regardless of the sealant you chose, to prepare it so it will actually help, you need to follow the manufacturer’s instructions precisely.
Step 4: Fill the crack
Use a putty knife to apply the epoxy or resin mixture carefully along the crack. Make sure to fill the entire crack length and smooth out the surface.
Step 5: Let it cure
Sealants usually take a few hours to dry, but patience ensures a strong bond.
Step 6: Remove the tape and clean up
Once the epoxy or resin has fully cured, gently remove the tape. Clean any excess material around the crack using a razor blade or putty knife.
When to Seek Professional Help
While tackling small cracks and minor repairs can be a rewarding DIY project, certain situations demand an expert’s attention. Here are some cases in which it’s best to leave everything as is and start researching for a trusted window installation contractor:
- Extensive damage | If the crack spans a significant portion of the window or the glass is shattered, it’s best to call a professional to avoid making the situation worse;
- Safety risk | If the cracked window compromises the structural integrity of your home, do not attempt to fix it on your own;
- Lack of experience or resources | Window repair requires specific skills, tools, and materials. If you are completely honest with yourself and understand that you don’t have any point from this list, relying on a professional will be a wise decision.
What’s more, if you attempt window crack repair, you may void the warranty if your window is still under it. Remember, professionals not only have the technical know-how but also have the experience to identify underlying issues that may cause window damage.
