Structural Survey & Inspection Services Across the UK

Cracks in the wall, a sagging roofline, movement you can’t explain. Guessing costs more than knowing. Xpanza’s structural surveys and inspections give you a clear engineer’s answer: what’s wrong, how serious it is, and what to do next, backed by photographs and a written report you can show your insurer, lender or solicitor.

Evidence before assumptions

Evidence Before Assumptions

Too many structural decisions are made on guesswork: a crack filled and forgotten, a wall removed without checking what’s above it, an extension designed over unknown ground. Our inspections replace assumptions with recorded evidence, so every decision that follows is built on fact.

1
Measured, not guessedCrack widths, levels and movement recorded with proper instruments, not eyeballed.
2
Photographed throughoutDated images of every defect, inside and out, so nothing relies on memory.
3
Cause before cureWe diagnose the mechanism, subsidence, settlement, failed lintel, drainage, before recommending any fix.
4
Plain-English verdictHow serious it is and what to do next, in language anyone can act on.
What we provide

What We Provide

Six inspection services, each ending in a written structural engineer report you can share with your insurer, lender, solicitor or builder.

01

Structural Inspection

A full visual assessment of the property’s structure: walls, floors, roof and foundations. The starting point when something doesn’t look right, or before you commit to buying.

Crack Assessment

Wall cracks mapped by width, direction and pattern, judged against the industry damage scale, with a verdict on whether the movement is historic or still active.

03

Structural Integrity Report

A formal written opinion on the structural condition of a building or structural element, prepared for insurers, lenders, solicitors and pre-purchase decisions.

04

Roof Inspection

Rafters, purlins, ridge, coverings and chimney stacks checked for spread, sag and decay, from inside the loft and out. The right check before a loft conversion or after storm damage.

05

Defect Diagnosis

Damp-related structural damage, timber decay, bulging brickwork, failed lintels: we identify the structural defect, trace its cause and set out the fix in order of priority.

06

Pre-Works Condition Survey

A photographic schedule of condition recorded before building work starts, protecting you and your neighbours if damage is disputed later. Essential on terraces, semis and party-wall jobs.

A report organised around evidence and decisions

Every inspection ends in the same thing: a report you can act on and share.

A

Inspection record

What was inspected, what was found, and the measurements behind it.

B

Photographic evidence

Dated, annotated photographs of every defect of concern.

C

Technical opinion

The likely cause, ranked by probability, and an honest assessment of severity: urgent, monitor or low risk.

D

Recommendations

What to do next, in what order: monitor, investigate further, or repair. And where the fix needs design work, we can take it straight into calculations and drawings.

03

Diagnosis and Report

Findings written up with photographs, the likely cause, an honest severity rating and clear recommendations.

04

Next Steps

Monitor, further investigation, or repair. If the fix needs structural design, we move it straight into calculations and drawings with the same team.

Commonly Asked Questions About Structural Surveys

Straight answers to the questions we’re asked most about structural surveys and inspections. Contact us if yours isn’t answered here.

It depends on the scope: a single crack assessment costs less than a full structural survey of the whole property. Use our cost calculator for an instant indicative estimate based on our published rate card. Your exact price is confirmed in writing after a free consultation.

The site inspection, measurements and photographs, an assessment of the cause and severity of each defect found, and a written report with clear recommendations. Everything is documented so you can share it with your insurer, lender or solicitor.

No. A homebuyer survey is a general condition overview carried out by a surveyor. A structural survey is an engineer’s diagnosis focused on the structure: walls, floors, roof and foundations, and specifically on defects like cracking and movement. When a homebuyer survey flags structural movement, this is the next step.

Take cracks seriously if they are wider than about 5mm, growing over time, diagonal or stepped around doors and windows, or reopening after being filled. Doors and windows sticking, or gaps opening between walls and ceilings, are further warning signs. Hairline cracks from drying shrinkage are usually cosmetic.

No. A survey supports insurance claims rather than harming your policy, and insurers often ask for an engineer’s report before settling a subsidence or movement claim. Our reports are written to give insurers the cause, severity and recommendations they need.

No. In many cases the right fix is removing the cause, managing tree roots or repairing leaking drains, rather than underpinning. Underpinning is a last resort for severe cases. Our report recommends the least disruptive effective solution.

Yes, with the right documentation. A clear structural report confirming the property is stable, or that remediation is complete, is usually enough to satisfy buyers, solicitors and mortgage lenders.

Yes. We’re based in Swansea and inspect properties across Swansea, Neath, Port Talbot, Llanelli, Cardiff and South Wales, as well as serving clients across the UK.

The site visit itself is usually under an hour for a focused inspection. Report timing depends on the scope of the survey; indicative timelines are shown in our cost calculator when you build your estimate.

Book a targeted structural inspection. Send us the survey report and photos of the areas flagged, and our engineer will diagnose the specific defects rather than repeating the general survey you’ve already paid for.
