Problem-led
Start with the question or visible symptom, then connect it to the appropriate service or further investigation.
SurveyAll Knowledge Centre
Property guidance built around real questions
Clear, practical explanations of home surveys, cracks, damp, water ingress, valuations and building work. Each guide is connected to the relevant SurveyAll service so you can move from understanding the issue to choosing a proportionate next step.
Practical guidance
Start with what you want to understand
These guides are written around recurring homeowner and buyer questions rather than around internal service names.
Cracks & movement
Cracks in walls: when should you investigate?
How to think about width, pattern, distortion, change over time and related movement signs.
Read guide Cracks & movementSubsidence, settlement or seasonal movement?
Why the words are not interchangeable and why the whole pattern matters before a cause is assigned.
Read guide Damp & moistureDamp, condensation or a leak?
Similar-looking marks can come from very different moisture mechanisms. Start with distribution and context.
Read guide Water ingressWater ingress: source, pathway and symptom
A practical framework for understanding why the visible stain may be some distance from the entry point.
Read guide Buying a propertyLevel 2 or Level 3 Home Survey?
Choose by property age, construction, condition, alterations and complexity rather than price alone.
Read guide Buying a propertyWhat does a Home Survey not cover?
Concealed areas, inaccessible spaces, specialist tests and service performance are common sources of misunderstanding.
Read guide ValuationsProbate and retrospective property valuations explained
What a historic valuation date means and how evidence is considered in the context of the market at that date.
Read guide Building workDefective building work: how to record useful evidence
A practical way to separate what was observed, what was supplied, and what still needs specialist confirmation.
Read guide Specific defectsWhen is a Specific Defect Survey useful?
When a focused inspection can be more proportionate than commissioning another whole-property survey.
Read guide Roof problemsRoof problems before buying: what should you look for?
Visible roof warning signs, loft clues, rainwater defects and when a specialist follow-up may be sensible.
Read guideHow the Knowledge Centre works
Useful guidance without pretending every property is the same
Source-led
Where technical or regulatory points matter, guidance links to recognised sources rather than inventing simplified rules.
Reviewed
Guides show a review date so time-sensitive standards and guidance can be revisited as requirements change.
Proportionate
General information does not replace a property-specific inspection, specialist test or legal advice where one is required.
South East London context
Guidance informed by the homes we inspect
SurveyAll regularly works with Victorian and Edwardian terraces, 1930s houses, post-war construction, flats, extensions and altered residential property across Greenwich, Lewisham, Bexley and Bromley. The guides stay broadly useful while recognising that age, materials, previous alterations and local ground conditions can materially change the interpretation of what is visible.
