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

When considering building extensions in Lewisham, there are several signs of potential problems you should watch for. Key indicators include cracks in walls, particularly around windows and doors, which can suggest settling issues or structural weaknesses. Water stains can indicate leaks or poor drainage, while uneven flooring may signal foundation problems. It's also essential to assess the roof; sagging or tiles that are missing can point to issues needing urgent attention.

Addressing these problems early can save you money in the long run. For example, fixing structural issues may cost around £3,000–£8,000, depending on severity, while water damage repairs might range from £1,500–£5,000.

Ensure that any builders you consider for your extension are certified, such as being registered with the NICEIC for electrical work or Gas Safe for any gas installations. Always verify the credentials of your contractors to ensure safety and compliance with regulations.
