Separate diagnosis from treatment
A paid survey may save money if it prevents unnecessary work. Conversely, some contractors include investigation within a treatment quotation. Compare what is actually being inspected and specified.
The moisture source may be inexpensive or extensive
A leaking downpipe joint is a very different job from external drainage work, cavity clearing or treating thick irregular masonry. The visible damp area does not tell you the repair cost.
Plaster and joinery add disruption
Salt-contaminated plaster, skirtings, sockets and radiators can all increase labour. Reinstatement and decoration may be excluded from a headline treatment price.
Basements are a separate scale of work
Below-ground waterproofing can involve membranes, drainage channels and pumps. It should not be compared with a small remedial DPC job simply because both are described as damp proofing.
