Before inspection
Useful evidence to gather before asking for advice.
A short record can make the advice more precise. You do not need to diagnose the issue yourself; just capture what you can see and when it happens.
- Photograph visible defects, stains, mould growth, cracks and affected surfaces.
- Note when the issue appears, whether it changes with weather, heating or occupancy, and which rooms are affected.
- Keep a record of previous reports, repairs, contractor visits and any recurring symptoms.
- Avoid covering up the problem before an inspection unless urgent safety or health action is required.
When to ask
Get independent advice when the decision matters.
The cause is unclear
Advice is most valuable when symptoms overlap and a single visible patch could have more than one possible cause.
Costs are escalating
A clear diagnosis can help avoid repeat repairs, unnecessary products and work that does not address the underlying defect.
You need a written view
A professional report can help owners, landlords, tenants, buyers and managers make decisions from the same evidence base.
Common questions
About this knowledge base.
What does the knowledge base cover?
Four areas: moving home, which covers surveys, ownership, costs and the buying process; maintaining your property, which covers subsidence, knotweed, conservatories, extensions and conversions; energy efficiency, which covers retrofit, insulation and solar; and a set of quick answers to the questions we are asked most, from damp and cracks to roof repair costs. Every guide is written by Professionally qualified surveyors.
Is the advice specific to the UK?
Yes. The guidance follows UK practice throughout, and where the rules differ between England and Wales, Scotland and Northern Ireland — as they do on planning and Building Regulations — the guides set out each position separately.
Can you advise on a problem I have already found?
Yes. Send us photographs of what you can see, a note of when it appears and whether it changes with weather, heating or occupancy, and any previous reports or repair records. We will tell you whether an inspection, a written report or a specialist referral is the right next step.
Do you sell treatments or remedial work?
No. We are consultants, not contractors, and we do not sell treatments, repairs or remedial products. That means the recommendation you receive is based on what the building needs, with nothing for us to gain from any particular outcome.
