5 Common Mistakes in Glass Repairs (And How to Avoid Them)

Glass is everywhere — from shopfronts to internal partitions, from windows to doors. And when it gets damaged, most people want a quick and affordable fix. But rushing into a glass repair without proper knowledge can lead to bigger issues down the road.

Here are the 5 most common mistakes people make during glass repair jobs — and what you should do instead.

❌ Mistake 1: Trying to DIY Complex Repairs

Fixing a tiny chip on a mirror? Maybe.Trying to replace a cracked shopfront glass panel? Don’t.

Why it’s risky:

• You could damage the frame or surrounding structure

• You might install it incorrectly, leading to leaks or security issues

• It may not comply with building regulations

✅ What to do:Call a professional. It’s safer, faster, and more cost-effective in the long run.

❌ Mistake 2: Ignoring the Root Cause

Sometimes, glass doesn’t just break for no reason:

• Is the frame warped?

• Are there signs of building movement?

• Was the wrong type of glass installed in the first place?

✅ What to do:Have your glazier inspect the surrounding structure before replacing the glass. Fixing the cause is just as important as fixing the glass.

❌ Mistake 3: Replacing Glass with the Wrong Type

Many people don’t know what type of glass was originally installed — and not all glass is interchangeable.

You could accidentally downgrade your:

• Security (using float glass instead of laminated)

• Insulation (using single-pane instead of double)

• Soundproofing (ignoring acoustic requirements)

✅ What to do:Ask for glass that matches (or improves on) the original specs. Check if it meets BS safety standards in the UK.

❌ Mistake 4: Poor Sealing and Finishing

We often get called to fix jobs done by other installers where:

• The silicone sealant has gaps

• The glazing beads are loose

• Water is leaking in

✅ What to do:Insist on proper sealing with weather-resistant materials. Ask for photos of previous work to judge finish quality.

❌ Mistake 5: Choosing the Cheapest Quote

We get it — price matters. But choosing a glazier just because they’re the cheapest often leads to:

• Incomplete or sloppy work

• No guarantees or insurance

• Cheap materials that don’t last

✅ What to do:Get at least 2–3 quotes, compare the scope of work, and choose based on value — not just price.

🧠 Bonus Tip: Think Long-Term

Sometimes, repairing the glass isn’t the smartest move.If you’ve had multiple repairs in a short period, or if your system is old and inefficient, it may be time for a full replacement or upgrade.
