What affects damp survey costs?
Property size
A one-bedroom flat is quicker to inspect than a four-bedroom detached house. Larger properties with cellars, lofts and multiple elevations need more time and therefore cost more.
Location
Travel time and regional property types affect pricing. We cover the West Midlands and the whole UK; remote or multi-site appointments may carry a small travel surcharge.
Report type
A simple damp check is cheaper than a mortgage report, damp and timber report, or thermal imaging survey. Lender-accepted reports often include extra documentation and liability cover.
Fixed-fee independent survey vs. contractor-led inspection
A contractor who also sells damp-proofing work may inspect for free or at a very low price, but the report can be influenced by the need to win remedial work. By contrast, a fixed-fee independent survey from surveyit.uk gives you:
- An unbiased diagnosis with no incentive to sell treatments
- Clear photographic evidence and moisture readings
- Lender-accepted reports for mortgage applications
- A fixed fee agreed upfront — no hidden extras
How much is a damp survey?
A damp survey is typically £200 to £500 plus VAT. A straightforward damp check on a one or two bedroom flat sits at the lower end, a full damp and timber report is usually £250 to £400, and a lender-accepted mortgage damp report is normally £300 to £500. Larger period properties with cellars, multiple elevations or difficult access sit above that range. We agree the figure with you in writing before the appointment, so the price you are quoted is the price you pay.
How long does a damp survey take?
Most damp surveys take one to three hours on site. A small flat with a single affected wall can be completed in under an hour. A three or four bedroom house with a cellar, sub-floor void and loft usually takes two to three hours because every elevation, floor void and roof space needs inspecting and metering. Your written report is issued within 24 to 48 hours of the visit, and urgent same-day reports can be arranged for mortgage deadlines.
What does a damp survey involve?
A damp survey is a diagnostic inspection, not a quote for remedial work. Ours covers:
- External inspection of ground levels, render, pointing, gutters, downpipes, flashings and airbricks to find the source of water ingress
- Internal inspection of walls, skirtings, floors, sub-floor voids and roof spaces where access permits
- Protimeter moisture meter readings at multiple heights, with deep-wall or salt-analysis testing where the diagnosis needs it
- Thermal imaging where cold-bridging, missing insulation or condensation risk is suspected
- Timber checks for wet rot, dry rot and wood-boring insect activity
- A written report with photographs, readings, the cause of each defect and costed remedial recommendations
