What are the signs of problems in building extensions in Caernarfon?

When considering a house extension in Caernarfon, it's crucial to be aware of potential issues that may arise. Common signs of problems include cracks in walls, which could indicate structural issues, or damp patches, suggesting moisture problems. You might also notice uneven floors or doors and windows that stick, which are signs of subsidence or foundation issues.

Addressing these problems early can save you money in the long run. For minor repairs, you might expect to pay around £200–£500. However, significant structural repairs could range from £1,500 for underpinning to over £5,000 for extensive foundation work. Always ensure that any builders you hire are qualified and certified, ideally with a UKAS-accredited body like the NICEIC or Federation of Master Builders (FMB).

If you notice any of these signs, it's best to consult with a local professional who can assess the situation accurately.
