At XP Coatings, we completely understand why many homeowners want to tackle small exterior repairs themselves. A quick fix for a hairline crack or a patch of tired render seems simple enough — especially with so many DIY videos online.
But we’re seeing more and more cases where these small jobs don’t last or end up needing to be redone professionally. It’s never anyone’s fault; exterior surfaces are just trickier than they appear.Here’s a helpful guide on why some DIY repairs don’t always go to plan, and when it might be worth giving us a quick call for advice.
🔧 Why DIY Repairs Can Be a Bit Challenging
Brickwork and render play a big part in keeping your home protected from the weather. When a repair isn’t carried out using the correct method or materials, you might notice:- Cracks returning
- Patches that don’t match the rest of the wall
- Moisture getting into the surface
- Repairs that lift, bubble, or fall away over time
🎨 Common DIY Issues We See
Here are a few of the things we’re called out to help with most often:✔️ Materials Not Quite Right
Render comes in many types — silicone, monocouche, sand & cement, acrylic — and each behaves differently. Using the wrong one can cause more problems later.
✔️ Colour Differences
Even when the product is correct, matching the exact colour of a weathered wall can be difficult without specialist pigments and tools.
✔️ Quick Fixes That Don’t Last
Hairline cracks often need reinforcing mesh or flexible fillers to stop them coming back.
🏠 When It’s Worth Getting Us In
If you notice cracks getting larger, render starting to hollow or “drum,” or patches that look damp, it’s worth having it checked properly. Most exterior issues are very manageable when caught early — and fixing them professionally often costs less than redoing a repair that’s failed.At XP Coatings, we’re always happy to offer advice, even if you’re not ready for a full repair. Sometimes a quick look and a bit of guidance is all you need.
