Farnworth sits in Greater Manchester, about 8 miles north-west of Manchester. We work across the BL4 district, including nearby Walkden, Bolton and Radcliffe.

Every inspection point in Farnworth is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Farnworth property is plain English: what we found, what it means and what, if anything, to do next.

Wind-driven rain is the first thing the surveyor weighs up. Greater Manchester has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
