What are key questions to ask a surveyor when you’re interested in a property? A buyer who asked only whether a property was “in good condition” later discovered costly roof repairs, so you’ll need more specific questions during your homebuyer or building survey. Ask what the inspection covers, which areas are excluded, and whether the surveyor will assess damp, structure, roofs, services, alterations, and pests. Clarify urgent repairs, likely costs, safety risks, and recommended specialist investigations—but one essential question can determine how useful the report really is.
Key Takeaways
- What areas will you inspect, and are any concealed, locked, specialist, or inaccessible areas excluded?
- Which defects affect safety, structural stability, damp protection, weatherproofing, or essential services, and how urgent are they?
- Could alterations, extensions, subsidence, pests, or unapproved work require specialist investigation or supporting documentation?
- What repairs are needed, when should they be completed, and what realistic costs include labour, materials, access, fees, and VAT?
- How might your findings affect insurance, mortgageability, value, maintenance, and my decision to proceed with the purchase?
What Will This Survey Cover?
A survey should assess the property’s accessible structure, condition, materials, defects, and any signs of movement, damp, timber decay, or other risks relevant to its type and age.
Ask your surveyor to confirm the inspection’s scope, including roofs, walls, floors, windows, services, outbuildings, boundaries, and grounds.
Clarify which areas won’t be inspected, such as concealed spaces, locked rooms, or systems requiring specialist testing.
The report should describe significant concerns, explain their likely implications, and recommend further investigations where necessary.
It may also support property valuation, although a valuation isn’t included in every survey.
Confirm whether the surveyor will comment on repair priorities, maintenance, and suitability for your intended use.
Discuss legal considerations too, because the survey won’t normally verify title, planning permission, building regulations, or guarantees.
Which Defects Should the Surveyor Check?
Your surveyor should check for defects that affect the property’s safety, stability, weatherproofing, durability, and likely repair costs. Ask whether they’ll identify visible signs of movement, cracking, subsidence, poor alterations, defective finishes, unsafe installations, and inadequate maintenance.
Foundation issues deserve particular attention, including uneven floors, stepped cracks, sticking doors, or changes in ground levels. Confirm that the surveyor will assess external walls, windows, doors, drainage, and outbuildings for deterioration or failure, without assuming hidden areas are sound.
Ask them to look for Pest infestations, such as wood-boring insects, rodents, nests, or damage, and explain any evidence they find.
You should also request clear photographs, severity ratings, likely causes, recommended next steps, and estimates of urgency, so you can negotiate confidently or budget for remedial work.
Can You Inspect Damp, Roofs, and Structure?
Ask whether your surveyor will assess signs of damp, including moisture sources, affected materials, and likely causes.
You’ll also want clear checks of the roof’s coverings, structure, drainage, and visible defects.
Confirm what structural elements they’ll inspect and whether specialist testing or further investigation is recommended.
Damp Assessment
Can you inspect the property for damp, roof defects, and structural concerns? Ask your surveyor to explain exactly how they’ll assess damp and whether their inspection includes moisture meters, visible staining, condensation, salt deposits, timber decay, and ventilation problems.
Confirm that they’ll distinguish rising damp, penetrating damp, and leaks from everyday humidity, rather than relying on one meter reading. Request a clear assessment of potential moisture intrusion, its likely source, and any areas requiring specialist investigation.
Ask whether they’ll inspect concealed spaces where accessible and identify limitations caused by furnishings, finishes, or restricted access.
You should also ask for a mold assessment, including likely causes, affected areas, health considerations, and recommended remediation.
Finally, confirm whether the report will prioritise repairs, estimate urgency, and advise which specialists should investigate further.
Roof and Structural Checks
When discussing roof and structural checks, ask your surveyor to inspect the roof coverings, flashings, gutters, chimneys, roof structure, loft space, walls, floors, ceilings, and visible foundations for defects or movement.
Confirm whether the inspection includes safe access to the roof and loft, or relies on ground-level observations.
Ask what defects they’ve identified, how serious they are, and whether they recommend immediate repairs or specialist investigations.
Request a detailed Gutter inspection to identify blockages, leaks, defective joints, and drainage problems that could cause damp.
A thorough Chimney assessment should cover leaning, cracked masonry, defective flashing, pots, and signs of water entry.
Ask whether movement suggests settlement, subsidence, rot, infestation, or inadequate alterations.
Finally, confirm repair priorities, likely costs, and whether you should obtain structural-engineer advice before exchanging contracts.
What Should You Ask About Services?
Ask the surveyor to assess the condition of visible services, including drainage, heating, electrical systems, and water supply.
Confirm whether utility connections serve the property exclusively and whether any defects, limitations, or upgrade costs could affect you.
If the building has shared facilities, ask who maintains them, how costs are divided, and whether planned works may create future liabilities.
Service Condition
Do the building’s electrical, plumbing, heating, drainage, and ventilation services appear safe, functional, and appropriately maintained? Ask your surveyor to describe visible defects, outdated components, leaks, corrosion, poor workmanship, unusual noise, or signs of inadequate servicing.
Confirm which systems they tested, which they could only observe, and whether access restrictions limited the inspection scope. You should also ask whether any installation appears unsafe, non-compliant, or likely to require urgent attention, while recognising that a survey isn’t a specialist contractor’s test.
Request clear advice about likely repair priorities, remaining service life, and whether you need qualified specialists to investigate further. Ask how the findings affect service quality, reliability, maintenance costs, and your immediate safety responsibilities.
Make certain the report distinguishes confirmed defects from recommendations for further testing.
Utility Connections
Have you confirmed how the property connects to mains electricity, gas, water, drainage, telecommunications, and any private or shared networks?
Ask your surveyor to identify connection points, meters, stopcocks, inspection chambers, overhead or underground routes, and any visible defects or access concerns.
Clarify whether each service is confirmed, assumed, or unverified, and request evidence where records or plans are available.
You should also ask who owns and maintains each connection, whether easements, wayleaves, or access rights affect your property, and whether supply capacity meets your intended use.
Discuss planned service upgrades, including likely costs, permissions, disruption, and lead times.
Ask whether the survey indicates outdated wiring, inadequate water pressure, drainage restrictions, or telecommunications limitations requiring specialist testing.
Confirm which findings need immediate investigation before exchange or construction.
Shared Facilities
How are shared facilities supplied, accessed, maintained, and paid for? Ask your surveyor to identify every service serving the building, including lifts, heating systems, water supplies, waste storage, lighting, parking controls, and security equipment.
Clarify whether you’ll share these facilities with other residents and whether access depends on keys, fobs, codes, or scheduled availability.
Request details of maintenance responsibilities, inspection records, repair history, and any known defects affecting communal areas.
Ask who manages the shared amenities, how contractors are appointed, and whether planned works could create disruption or additional costs.
Your surveyor should explain service-charge arrangements, reserve funds, insurance contributions, and liability for damage or breakdowns.
Check for disputes, arrears, proposed major works, and restrictions in the lease or management documents before you commit to purchase.
Are There Signs of Extensions or Alterations?
Look for differences in brickwork, rooflines, render, windows, or internal layouts that may indicate extensions or alterations. Ask your surveyor to identify these extension signs and explain when the work may have occurred.
Changes in materials, uneven junctions, altered roof pitches, blocked openings, or mismatched finishes can reveal additions that aren’t obvious from inside. Request confirmation that the layout appears consistent with available plans, planning records, and building regulations documentation.
Your surveyor should distinguish permitted development from work that may have required approval, and note whether an alteration affects the property’s original design or use.
Ask specifically about converted lofts, garages, porches, removed walls, and relocated kitchens or bathrooms. These alteration indicators can highlight undocumented changes, so clarify what evidence you should obtain before proceeding with your purchase.
Which Repairs Need Urgent Attention?
Ask your surveyor to identify repairs that need urgent attention and explain the risks of delaying them. Ask whether any defect threatens your safety, the building’s stability, weatherproofing, or essential services. Your surveyor should distinguish urgent repairs from issues you can monitor, so you can act in the right order.
Request clear evidence for each recommendation, including photographs, affected areas, likely causes, and signs of worsening damage. Immediate concerns might include unstable walls, dangerous roof defects, exposed electrical wiring, substantial water penetration, active leaks near electrics, or failed drainage undermining foundations.
Ask whether you should restrict access, switch off services, or arrange temporary protection before qualified contractors attend.
Confirm which specialist should investigate each problem and whether further inspections are necessary. Record every urgent repair in your survey notes, then seek professional advice promptly rather than relying on assumptions or cosmetic fixes.
How Much Could Repairs and Maintenance Cost?
Once you’ve identified urgent defects, ask your surveyor for a realistic indication of likely repair and maintenance costs. Request separate allowances for immediate work, medium-term repairs, and routine upkeep, rather than one broad figure.
Ask whether estimates include labour, materials, access equipment, professional fees, VAT, and potential hidden damage. Your surveyor may not provide a contractor’s quotation, but they can explain the likely scale of expenditure and identify items needing specialist quotes.
Ask which costs could vary considerably and what assumptions support the assessment. Discuss the building’s age, construction, condition, and systems when considering future maintenance planning.
You should also ask how often major elements, such as roofs, windows, boilers, or cladding, might require attention. Use this information to compare affordability, negotiate confidently, and budget for ownership responsibly.
What Do the Survey Findings Mean?
What do the survey findings mean? Ask your surveyor to explain each defect in practical terms, including its severity, likely cause, and potential consequences.
You should understand which problems require immediate action, which you can monitor, and which represent normal age-related wear. Request clear priorities rather than relying solely on condition ratings or technical terminology.
Ask how the findings affect safety, mortgageability, insurance, value, and future maintenance.
Historical context can change the interpretation: movement may reflect an old, stable issue rather than active structural failure. Your surveyor should distinguish confirmed defects from areas requiring specialist investigation and recommend appropriate contractors or engineers.
Check the surveyor qualifications and relevant experience with similar properties.
Before proceeding, obtain realistic repair estimates, seek specialist reports where advised, and use the findings to negotiate, budget, or reconsider the purchase.
Conclusion
A good survey turns a house from an attractive picture into a clear, detailed map. Ask your surveyor to identify hidden damp, structural movement, unsafe services, questionable alterations, pests, and repairs that could drain your budget. Confirm what needs urgent action, what can wait, and which specialists or cost estimates you’ll need. Then use the findings to negotiate confidently, plan repairs, or walk away. Don’t rely on appearances alone—let the report illuminate what lies beneath.
