Book Your Complimentary In-Depth Survey in Dorset, Hampshire & Wiltshire

First, who's enquiring?
























A survey that looks at the whole property
Damp is rarely a single-cause problem. Our In-Depth Survey follows moisture from the outside in, so the remedy we recommend fixes the source.
External envelope
Brickwork, pointing, DPC height, drainage, gutters, downpipes and external ground levels.
Internal diagnostics
Moisture meter readings, salt analysis, mould, condensation, thermal bridging and plaster condition.
Subfloor
Subfloor ventilation, air bricks and the condition of joists beneath suspended floors.
Roof & loft
Rafters, felt, signs of leaks and moisture tracking into the roof space.
Timber
Woodworm, wet rot and dry rot, each recorded with a clear severity rating.
Annotated photography
Every defect photographed and marked up using 14 colour-coded annotation types.



Professional diagnostics and enriched property data
Every finding is backed by readings and photographs. We also enrich your report with official data about the property, so recommendations reflect its age, construction and setting.
All advice is aligned with the guidance of the Property Care Association (PCA), the governing body for damp, mould and timber in the UK.
Clear answers before we leave
Your report is produced on-site during the same visit. No waiting weeks for paperwork, and no vague verbal estimates.

“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Your questions about the In-Depth Survey
We do the work. Proofterior is a specialist damp, mould and timber contractor, not a referral service that hands you a report and disappears. Our own team of vetted, Proofterior-trained specialists carries out every treatment we recommend, from tanking and timber repairs to drainage, ventilation, re-plastering and exterior protection. That means one accountable company from the first survey through to the final guarantee, with every job managed and guaranteed by Proofterior.
Yes, and it is one of the most valuable things we do. If a mortgage valuation or building survey has flagged damp or timber concerns, our In-Depth Survey gives you a specialist diagnosis and a fully priced remedial plan in writing. You can use it to renegotiate the asking price, budget accurately, and plan works to line up with completion. Many of our clients book us in before they exchange, and we can often schedule the works to begin as soon as the keys are yours.
It is genuinely complimentary and completely no obligation. You keep the full written report and itemised plan whether or not you instruct a single item of work. There is no catch and no pressure, it simply lets us show the standard we work to.
A thorough inspection of the external walls, internal rooms, the subfloor and the roof where accessible, with professional moisture readings, salt and timber analysis, and annotated photographs of every significant finding. We also pull in property data such as EPC rating, flood risk zone, construction age and listed or conservation status. It all comes together as a plain-English report with an itemised, priced remedial plan, produced the same visit.
Yes. You can spread the cost of your work with 0% finance, with interest-free options over up to 24 months and longer repayment plans available up to 10 years, subject to status. It means you can get the work your home needs now and pay over time, with the interest-free plans costing you exactly what the work costs and nothing more. Finance is arranged through a regulated credit broker, and your surveyor can talk you through the options on the day.
No. Your surveyor is there to diagnose the real cause and give you the facts, not to pressure you. You decide what, if anything, to go ahead with, on the day or in your own time. If a problem is minor or does not need us, we will tell you that too.
Yes. Every job is backed by our 25-year workmanship guarantee, with an optional 30-year insurance-backed guarantee available for added peace of mind. All work is carried out by our accredited in-house teams and completed to PCA standards.
Assessments are typically bookable within the week. Once you instruct us, work can often begin quickly, and where you are buying or selling we can line the start date up with your completion. Damp problems rarely wait, so neither do we.
Yes. Proofterior is ISSE accredited, Biokil Crown approved and Checkatrade verified, and we hold a 4.9 out of 5 rating across our reviews. You are dealing with qualified specialists, not general builders.
We cover Dorset, Hampshire and Wiltshire, with in-house teams working right across the south.
