Who this is for

Owners seeing recurring stains, damp patches, peeling finishes, active leaks or unexplained water damage
Housing societies investigating basement, terrace or common-area water ingress
Buyers or tenants who need the visible condition recorded before choosing the next specialist step

Common reasons to enquire

An unexplained stain, damp patch, active leak or water damage appears during rain, after plumbing use or at a seasonal interval
Several possible water sources make responsibility unclear
A previous repair was completed but symptoms have returned

Defined scope

What the inspection can cover

Before booking, we confirm the inspection areas, method and visit preparation.

Condition mapping

Visible staining, dampness, efflorescence, peeling, cracking and finish damage in accessible areas
Relationships between symptoms and accessible roofs, wet areas, openings, joints, plumbing routes or drainage
Locations that distinguish current observations from historic marks and customer-reported timing

Context and pathways

Recent weather, plumbing use, occupancy, repairs and symptom timing supplied by the customer
Plausible water pathways ranked as working hypotheses, not proven concealed causes
Gaps that may require monitoring, a controlled test, opening-up or another specialist

Method and evidence

Tools connect each observation to clear, location-linked evidence

Visible, moisture and thermal evidence

Visual observation and location-linked photographs
Comparative moisture-indicator readings on suitable accessible materials when included
Included thermal imaging across affected areas, possible water pathways and unaffected comparison areas
Paired thermal and visible capture for repeatable moisture-related temperature patterns, including patterns without visible dampness
Simple water tests performed under an agreed, safe and permitted method designed to protect finishes

Field evidence

Readings and paired images, kept in context

A moisture reading or thermal pattern contributes to the investigation alongside accessible site conditions and unaffected comparison areas.

Moisture meter held against an accessible interior wall — **Moisture meter check during a BuildInspect inspection**Instrument readings are recorded with the location and inspection context; they are not treated as a concealed-cause diagnosis by themselves.

Thermal image of a common washroom fitting with measurement markers; recorded range 28.1 to 33.3 degrees Celsius — The images are kept together so the thermal pattern can be located in the visible scene. Recorded centre temperature: 29.2°C. Interpretation depends on site conditions, comparison areas and the confirmed scope.

Visible-light photograph of the common washroom fitting paired with thermal capture RB00010X — The images are kept together so the thermal pattern can be located in the visible scene. Recorded centre temperature: 29.2°C. Interpretation depends on site conditions, comparison areas and the confirmed scope.

How the scope moves

From a clear brief to usable next action

01
Build a symptom timeline around weather, use and previous repairs.
02
Map visible and thermal patterns across affected, pathway and comparison areas.
03
Separate inspected facts from possible pathways and unresolved questions.
04
Choose monitoring, targeted opening-up, specialist testing or a separate repair scope.

Access and preparation

Help the visit answer the real question

Share when the problem appears and photographs from an active event
Provide known repair history and relevant plumbing, terrace or drainage information
Arrange permission to access both sides of the affected construction where possible
Do not conceal or repaint an affected area immediately before the visit
Tell us about electrical, access, contamination or other safety concerns

After the report

Keep closure evidence separate from promises

Preserve dated evidence while the symptom is active
Confirm the responsible party and access needed for the next investigation
Use a targeted test or repair scope based on supported evidence
Observe through the relevant weather or usage cycle and reinspect before closure

Clear next steps

Questions that need a different method or specialist

The report clearly shows what was reviewed, what remains open and the practical next step.

A dry visit may not reproduce intermittent or weather-dependent leakage, and one inspection may not isolate a concealed source.
Opening walls, flood or pressure testing, laboratory sampling and long-term monitoring require separate agreement and controls.
The visit is not a structural, indoor-air-quality, mould, electrical-safety or public-health certification.
Unsafe or contaminated areas are not entered; health, electrical or structural warning signs require the appropriate specialist.
Optional third-party repairs are separate from the inspection and cannot influence the recorded findings.

Questions before booking

Practical answers before you book

Can one visit identify the exact source of a leak?

Sometimes evidence supports a strong pathway, but water can travel from its source and conditions may be inactive. The report labels source explanations as hypotheses unless a suitable test establishes more.

Does a moisture-meter reading prove leakage?

No. Readings depend on the tool, material and conditions. They are interpreted with visible evidence, comparison areas and symptom history; they do not identify a source by themselves.

Should I wait for rain before booking?

Not always. Existing evidence may be useful, while a rain-linked symptom may need photographs, monitoring or a follow-up during suitable conditions. Share the pattern so the visit can be planned.

How is thermal imaging used during the visit?

Moisture-focused thermal imaging is included in the base leakage/dampness scope and base quote. Coverage maps affected areas, possible water pathways and unaffected comparison areas. Repeatable moisture-related temperature patterns are documented with paired thermal and visible images and measured temperature ranges.

Will BuildInspect carry out the repair?

No. BuildInspect's inspection and report remain independent of repair work. If you request a referral, the provider is a disclosed third party with a separate scope and quote; reinspection is also separately agreed.
