Guided starting points

Choose the question closest to your situation. Each route links to a focused set of reviewed library entries and keeps the underlying technical evidence on those linked pages.

Ceiling stains after rain
The ceiling stain appears or worsens after rain. Where should I start?
This proof route is limited to rain-linked ceiling staining and one selected slate-roof term. It does not cover every possible source of a ceiling stain.

Cracks in walls
I have found a diagonal or stepped crack. Where should I start?
This proof route is limited to diagonal or stepped cracking, one selected bay-window term and an approved post-survey path. It does not diagnose the cause of a crack.

Damp patch on an internal wall
I have found a damp patch. Which reviewed explanations should I compare first?
This proof route compares two reviewed explanations for internal damp staining: penetrating damp through solid walls and condensation on cold surfaces. It does not diagnose a particular property.

After a Level 3 survey
My Level 3 report identifies damp or structural movement. Which approved path should I open?
This proof route lets you choose between the approved significant-damp and structural-movement after-survey records. It is not a general interpretation of all Level 3 report wording.

Victorian solid-wall house context
How should I start when the property is a Victorian terrace?
This proof route is limited to the approved Victorian terrace construction and era fields, selected observations and a survey-scope choice. It does not claim that any defect is present or common.

Recommended next step

The proportionate instruction depends on the building, the concern and what an inspection can reasonably establish. HCS confirms the scope before you book.

Speak to a surveyor first

We confirm the proportionate instruction before quoting.

Also consider

Instruct a RICS Level 3 Building Survey — Detailed survey for older, altered, listed, non-standard or defective London property.
Not sure Level 2 or Level 3? Use the survey chooser — Use the live HCS tool for an indicative comparison, then confirm the scope before instruction.
Instruct a building pathology / defect survey — Cause-led diagnosis for a defined damp, leak, crack or fabric problem — not a full purchase survey.

Ask a surveyor

Not sure what this means for your property? Speak with a Chartered Surveyor atHampstead Chartered Surveyors & Building Consultancy.

General library guidance is not a survey of your building. A short conversation helps confirm the proportionate next step.

From Survey Findings to Remedial Design, Tendering & Execution

Once our RICS chartered building surveyors have diagnosed the root cause of a defect through a Specific Defect & Building Pathology Investigation or RICS Home Survey, you can either instruct Hampstead Chartered Surveyors independently for JCT Contract Administration to tender the works to external contractors, or elect our joined-up group design-and-build route alongside our sister practices:

Hampstead Architecture & Planning: Architectural drawings, conservation-area and listed-building consents, structural engineering coordination, and Building Regulations packages translated directly from the survey diagnostics.
Hampstead Renovations: Principal contractor remedial execution, heritage masonry and roofing repairs, damp and timber remediation, and full residential refurbishments backed by £5M public liability, £10M employers' liability and contractors' all risks cover alongside Hampstead Chartered Surveyors' RICS-regulated Professional Indemnity Insurance (PII).

RICS Impartiality Note: Where Hampstead Chartered Surveyors acts as independent JCT Contract Administrator or Party Wall Surveyor, works are tendered strictly to independent third-party contractors in accordance with RICS conflict-of-interest governance.

Request a Specific Defect Inspection or Post-Survey Fee Quote

All fees are quoted transparently plus VAT (Specific Defect & Building Pathology inspections from £595 plus VAT).
