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

When considering a building extension in Bexley, look out for several signs of potential problems. Common indicators include significant cracks in walls or ceilings, especially if they're wider than 5mm, which may suggest foundational issues. Dampness or mold in areas adjacent to the extension can indicate improper drainage or insulation problems. Additionally, misaligned doors and windows can signal structural movement and require urgent attention.

If you observe any of these issues, it’s essential to consult a professional builder. Typical costs to fix these problems can range from £1,500 to £5,000, depending on the severity of the damage and the required repairs. Always ensure your builder is certified, such as being NICEIC registered for electrical work or Gas Safe for any gas-related tasks associated with your extension.

Addressing these problems early can prevent more significant, costly repairs down the line. Looking for professionals in your area? Find vetted providers on TradeMatch.
