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

When considering a house extension in Willesden, certain signs indicate potential problems that may require fixing. Cracks in walls or ceilings, particularly those that appear suddenly or are wider than a few millimetres, can signify structural issues. Damp patches or mould growth is another troubling sign, often indicating water ingress or poor insulation that needs addressing. Additionally, if doors or windows are sticking, it may point to shifting foundations or inadequate support structures.

To resolve these issues, hiring a qualified builder certified by bodies like the Federation of Master Builders (FMB) or NICEIC is crucial. Repair costs can vary; for instance, fixing structural cracks might range from £300 to £1,500, while rectifying damp issues could cost between £500 and £2,000, depending on severity.

Always consult with a professional for a thorough assessment before proceeding with any building work.
