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

When considering house extensions in Durham, it's essential to look for signs of underlying issues that could escalate if not addressed. Common indicators include cracks in walls, uneven floors, or doors and windows that stick or don't close properly. These issues could suggest foundation problems or inadequate structural support.

If you notice any of these signs, consult a qualified builder as soon as possible. Having an extension built can cost between £1,200 and £2,500 per square meter in 2026, depending on materials and complexity. Prioritize hiring a builder who is NICEIC or FMB certified to ensure compliance with safety and building regulations.

Additionally, if you're planning to convert a loft or garage, watch for dampness or water ingress, as these can lead to significant structural damage if left unchecked. Regular inspections and maintenance are crucial in preventing costly repairs and ensuring the longevity of your build.
