What to Check Before Buying a House in the UK? Don’t Miss These Structural Red Flags!
Buying a home is one of the biggest investments you’ll make and if you’re not careful, it can come with hidden structural problems that cost thousands to fix. In this blog, we break down what to check before buying a house in the UK, especially when it comes to overlooked issues like cavity wall tie failure, damp, and defective cavity wall insulation. These are the silent killers of property value and they often go unnoticed until it’s too late.
1. Exterior Walls: Look for Warning Signs of Wall Tie Failure
The first thing you should check before buying a house is the external brickwork. Warning signs include:
- Horizontal cracks between bricks (a major red flag for cavity wall tie failure)
- Bulging or bowing walls caused by walls detaching due to corroded or broken ties
- Rust stains or blowouts, a clue that metal ties inside the wall are failing
These problems can lead to serious structural movement. Always consider a professional wall tie survey if you spot any of these issues.
2. Check for Damp
Many homes are freshly painted before viewings, but that doesn’t mean they’re dry underneath. Damp can be a sign of cavity wall insulation problems, roof leaks, or poor ventilation. What to look for:
- Peeling paint or bubbling plaster
- Musty smells, especially near external walls
- Mould, condensation, or cold spots
- Discolouration on walls or ceilings
Damp isn’t just unpleasant, it can lead to health issues and signal deeper structural faults. Always ask if the property has had damp surveys or insulation work done.
3. Ask These Key Questions Before Buying
If you’re wondering what to ask before buying a house, start with the structure.
- Has cavity wall insulation been installed? When?
- Has the property ever had a wall tie inspection?
- Are there any structural guarantees or damp warranties?
- Have repairs been done professionally and documented?
If the seller or agent can’t answer confidently, that’s a red flag.
4. Get a Specialist Survey Before Exchanging Contracts
A standard homebuyer’s survey might not spot wall tie failure or insulation issues. That’s where a specialist comes in. CavClear offers surveys for:
