Pre-purchase Damp & Timber Surveys
Buying a property?
Need to know before you purchase?
A large number of our clients contact us after damp has been flagged in a Level 2 or Level 3 Homebuyer Report. These surveys often highlight “possible damp” and recommend further investigation, but rarely identify the true cause or extent of the issue.
That’s where we come in.
We carry out damp and timber surveys for prospective buyers, providing a clear, unbiased assessment of the property. Our inspections determine whether damp is genuinely present, what’s causing it, and whether any remedial work is actually required.
Unlike contractor-led reports, our surveys are not driven by sales. We focus on accurate diagnosis, helping you avoid unnecessary treatments and giving you the confidence to proceed, renegotiate, or walk away if needed.
No sales agenda
Impartial, evidence-based advice focused on accurate diagnosis first
Targeted solutions
We distinguish between condensation, penetrating damp, plumbing leaks, ventilation/insulation issues, and timber risks
