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

When undertaking building work in Lewisham, it's crucial to identify signs of potential problems early. Common indicators include cracks in walls (especially around windows and doors), uneven flooring, and moisture or damp patches on walls. These issues might suggest structural damage or poor workmanship, particularly in house extensions or loft conversions. If you notice any of these signs, it's essential to act quickly.

In 2026, the average cost to rectify such issues can range from £1,000 to £5,000, depending on the severity and the type of repairs needed.
