When you spot a concerning crack in your glass stovetop, it’s alarming to consider replacing the entire appliance. However, small cracks can sometimes be addressed effectively with temporary DIY fixes to buy more time before investing in a costly replacement.
This guide covers several simple solutions until the stove can be professionally repaired. With the right repair method and careful use, a troubled cooktop can often continue functioning safely for countless more meals.
Assessing the Damage
When you notice a crack in your glass stovetop, the first step is to take a close look at the damage. This will help you decide if a temporary DIY fix is a good option or if you need professional help.
Types of Cracks
There are a few different kinds of cracks you might see:
- Hairline cracks – These are very thin lines on the surface. They look like little spiderwebs.
- Chips – Small pieces of the glass are missing from the edge or corner.
- Deep cracks – These cracks go deeper into the glass. They are wider and more visible.
Should You Try a DIY Fix?
Can you repair it yourself, or do you need a professional? Here are some questions to help you decide:
- Is it just a minor hairline crack or chip? These small flaws are the best candidates for a DIY temporary fix.
- Is it a deep crack or are multiple areas damaged? Severe cracks require professional help. DIY fixes will not be safe or last long.
- Does the crack affect the stovetop’s performance? If it impacts heating, it likely needs replacement.
- Are there any manufacturer warnings? Check your manual to see if they recommend against repairs.
When in doubt, it is better to call in a pro to inspect your glass stovetop and advise you. Safety comes first!
Time for a New Stovetop?
In some cases, you may need to replace the whole stovetop:
- If there are many cracks all over the surface
- When deep cracks cannot be repaired
- If the damage interferes with heating and performance
- When the manufacturer recommends replacement over repair
Replacing a glass stovetop can cost $200-$1000. But your safety is most important!
Safety Precautions
When dealing with a damaged glass stovetop, safety should always come first. Follow these tips to stay safe during a DIY temporary fix:
Turn Off the Power
Before doing any work, make sure to turn off power to the stovetop at the circuit breaker. No power means no chance of electric shocks or burns.
You can check that the power is off by turning on a burner. If it doesn’t heat up, you are good to proceed.
Use Protective Gear
Wear safety glasses to shield your eyes from bits of glass or adhesive. Neoprene gloves guard your hands from sharp edges and heat. You can find affordable glasses and gloves at any hardware store.
Ventilate the Area
If using adhesives like epoxy or silicone, make sure the room is well-ventilated. Open windows and use fans to circulate fresh air. Don’t breathe in toxic fumes!
Other Tips
Work slowly and carefully. Clean up spills right away. Follow all directions from the product labels. Rushing through a repair can lead to injuries or mistakes.
Temporary Fix Options
If your glass stovetop only has minor damage, a DIY temporary fix can help extend its life. Here are some options to consider:
Epoxy
Epoxy is a two-part adhesive that hardens into a glass-like finish.
- Use high-temp epoxy made for stoves and ovens. Regular epoxy will fail under heat.
- Mix and apply as directed on the package. Fill cracks flush with the surface.
Pros: Bonds well, leaves a smooth finish and is heat resistant.
Cons: Can yellow over time and wear away under daily use.
Duration: It may last several months with careful use.
High-Temperature Silicone
Silicone sealants made for high heat can fill cracks in glass tops.
- Pick a silicone rated for at least 500°F temperatures. Check the product details.
- Apply a thin layer and smooth with a popsicle stick. Let cure fully.
Pros: Flexible, easy to apply, heat resistant.
Cons: Not as strong a bond. It can peel over time.
Duration: May last 2-6 months with careful use.
Specialized Glass Repair Kits
Some windshield repair kits can be adapted for glass stove repairs.
- Buy a vacuum-type injector kit. This pulls adhesive deep into cracks.
- Follow kit directions to prepare, inject, and cure adhesive.
Pros: Repairs deep cracks, binds strongly, and leaves a smooth finish.
Cons: More costly, not made for stovetops specifically.
Duration: Up to 1 year if done properly.
Alternative Methods
You can get creative with materials like:
- Clear nail polish to fill in small scratches
- Sugru moldable glue to patch corner chips
- High-temperature tape to cover cracks
But these tend to be less effective temporary fixes. Make sure any materials can withstand stovetop heat.
Post-Repair Care
Once your temporary fix is complete, you’ll need to give it some extra care while it cures and as you use the stovetop.
Curing Time
Don’t use the stovetop for at least 24 hours after applying a repair. This allows adhesives to fully harden and cure. Check product labels for specific cure times.
Cleaning Tips
Use soft sponges and mild dish soap to clean the stovetop. Avoid abrasive scrubbers or harsh chemicals which could damage the repair.
Rinse well and completely dry the surface when done washing. Standing water can loosen adhesives over time.
Daily Use
Take extra care when cooking after a repair. Avoid slamming pots and pans around. Sliding them gently will put less stress on the fixed areas.
Use medium or low heat settings as much as possible. High heat can degrade temporary fixes more quickly.
Check Your Repair
Inspect the repaired cracks occasionally as you use the stovetop. Make sure adhesives remain intact and no new cracks form.
Contact a professional right away if you notice the repair failing or new damage around the cracks. Don’t take chances with your safety.
With proper care, your temporary fix can buy you some extra time before needing a professional replacement. But always put safety first!
Long-Term Considerations
A temporary DIY fix won’t last forever. At some point, you’ll need a more permanent solution.
Impact on Performance
Over time, damage and repairs can affect how well your stovetop works. You may notice:
- Longer preheat times
- Uneven heating or hot spots
- Sections not heating up
- Cracks getting bigger
Once the flaws start impacting performance, it’s time to replace the glass top.
When to Repair vs. Replace
If your temporary fix lasts six months or less, a professional repair may be the next best step. Repairs can cost $100-$300.
But if damage is severe or the stovetop is over 5 years old, replacement may make more sense. New glass tops often cost $200-$500 installed.
Cost Comparison
DIY temporary fix: $20-$50 for materials
Professional repair: $100-$300, lasts 1-2 years
Professional replacement: $200-$500, lasts 5+ years
Replacing is the most expensive option but is a permanent solution. Think long-term when deciding the next steps!
Safety First
If cracks reappear or cause functioning issues, stop using the damaged stovetop immediately. Consult a pro to discuss repair vs replacement. Don’t keep using a stovetop that’s unsafe.
Prevention Tips
While you can’t always prevent cracks, there are some things you can do to avoid damage:
Cookware Selection
- Use pans with smooth, flat bottoms to distribute heat evenly.
- Look for pans labeled “induction ready” for the best compatibility.
- Avoid using pans with thin, warped bottoms.
Handling and Cleaning
- Always lift pans straight up; don’t slide them across the glass surface.
- Clean the stovetop after each use to avoid baked-on spills.
- Use non-abrasive pads and scrub gently to keep the glass looking new.
Inspection and Maintenance
- Do a visual check of the glass top every week or so.
- Call a pro right away if you notice any cracks starting. Early repairs are easier.
- Have the stovetop professionally cleaned if mineral deposits build up.
Use Low to Medium Heat
- High heat can put extra stress on the glass over time.
- Opt for medium or low settings whenever possible to preserve the glass top.
With careful use and regular inspections, you can help your glass stovetop last for many years before needing repairs or replacement. Prevention is always easier than fixing damage after it happens!
Conclusion
Dealing with a cracked glass stovetop can be frustrating. But there are ways to temporarily fix minor damage yourself and extend the life of your appliance.
To recap, hairline cracks or small chips are the best candidates for DIY repairs using epoxy, silicone, or glass repair kits. Always take safety precautions and care for any repairs properly.
For more severe cracks, it’s best to call in a professional. They can determine if repair or full replacement is needed. Don’t take risks with damaged glass.
Prevention is also key. Being gentle with the stovetop and doing routine checks can help avoid cracks in the first place.
With some basic DIY skills and preventive care, you can squeeze a few more years out of your glass stovetop before needing to replace it. But don’t hesitate to call a pro when the damage is beyond your abilities. Some repairs are just not DIY-friendly.
