RICS-qualified surveyors, building condition reports








Cardiff homes vary sharply by street and building era. Our surveyors carry out detailed building inspections across Cardiff Bay, the city centre and the wider Cardiff postcode area, where terraced houses, flats and larger family homes often sit side by side. A full building survey in Cardiff suits older buildings, altered homes and properties with signs of wear. It gives you a clear view before you commit to a purchase.
We inspect the visible structure, roof space, walls, floors, drainage, damp, timber and services, then set out what needs attention in plain English. That matters in Cardiff, where homedata.co.uk records show an average property price of £253,000 between April 2025 and March 2026, with established homes at £251,000 and newly built homes at £397,000. The same data shows 12,000 sales in the last twelve months, down 12.1% (-1,800 transactions), so buyers often have limited room for costly surprises. A building survey helps you see the repairs, not just the purchase price.

Our surveyors inspect the parts of a Cardiff property that often drive repair bills later. That means the roof structure, chimney details, external walls, pointing, floors, damp proofing, joinery, drainage and any visible movement. A building survey also looks at boundaries, outbuildings and alterations, so a buyer understands how the fabric fits together. In a city with taller buildings added around Cardiff Bay and the centre since 2000, that wider view matters.
We do not just record defects. We explain what is urgent, what can wait, and where a specialist may be needed after the visit. In the Cardiff postcode area, terraced homes made up 44.4% of sales, semis 26.7%, detached houses 17.8% and flats 11.1%, so the inspection method has to suit very different building types. A flat in Cardiff Bay needs a different reading to a terrace near the city centre, even when both look tidy from the street.

homedata.co.uk records show the Cardiff postcode area saw 12,000 sales in the last twelve months, and the average price rose by £5,200 to £253,000. That volume hides a wide spread of property types. Terraced homes accounted for 44.4% of sales, while flats made up 11.1%, and that split tells us buyers are looking at everything from older rows to new apartments around Cardiff Bay. A building survey is the sensible check when the stock is varied and the repair history is not obvious.
The city has changed quickly since the 1980s, with major development around Cardiff Bay and a city centre skyline that has grown taller since 2000. Some homes are straightforward, but others have been altered, extended or converted in ways that hide defects from a viewing. Older terraces can mask damp, roof wear or timber decay, while newer flats can still suffer from water ingress, poor detailing or movement at junctions. Our surveyors judge the building on site, not the marketing copy.
Cardiff is also the capital city and main commercial centre of Wales, with a population around 350,000. That scale means the housing stock ranges from small flats to substantial detached houses, and repair standards vary just as widely. If you are buying in the city centre, around Cardiff Bay or in a suburban street with long-established homes, the full building survey gives you the clearest read on condition. It is the right choice when the property is older, larger or has been changed over time.
Terraced homes in Cardiff often hide wear that only shows up once our surveyors open up the detail. We regularly look for damp staining, roof slippage, cracked render, failing pointing, timber decay and movement around bay windows or rear extensions. Those issues are not limited to one part of the city, but they can be harder to spot in the older streets closer to the city centre. A quick viewing rarely tells the full story.
Across Cardiff Bay, newer apartments bring a different set of checks. Water tightness around balconies, roof coverings, service penetrations and signs of condensation all matter, especially where there has been a lot of recent construction since the 1980s. We also check outdated electrics, ageing plumbing and poor ventilation where alterations have been made without enough care. Small faults can become expensive if they are missed before exchange.

Tell us about the Cardiff property, then we match the inspection to the home, whether it is a terrace in the city centre or a flat in Cardiff Bay.
We appoint an RICS-qualified surveyor with local knowledge of Cardiff Bay, the city centre and the wider Cardiff postcode area.
The visit usually takes 3-4 hours. We inspect the visible fabric, roof space if accessible, drainage, damp, timber, services and external defects.
We write up the findings, assign condition ratings and set out repair priorities in plain English.
You usually receive the report within 5-10 working days, with clear notes on risks and next steps.
If the report flags cracking, damp or movement, we explain whether a specialist should look again before you proceed.
A building survey report gives you the clearest read on a Cardiff property's condition. It sets out what our surveyors saw, where the main defects sit and how serious each issue looks at the time of inspection. We use condition ratings so you can separate minor wear from problems that need prompt attention. That is useful whether the property is a terrace near the city centre or a flat in Cardiff Bay.
The report also helps with cost planning. If we identify a roof that needs work, moisture ingress around a chimney, or timber decay in a rear extension, you can speak to contractors with a better brief and ask the seller for a price discussion if needed. Buyers often use the findings to renegotiate, because the report shows the cost of fixing what was missed during viewings. Homedata.co.uk price data already shows a city where established homes average £251,000, so unexpected repairs can change the numbers quickly.
Where the report points to movement, hidden damp or more complex failure, we may recommend a specialist follow-up. That might be a structural engineer, a drainage contractor or a timber expert, depending on what the Cardiff property actually needs. A building survey does not replace every specialist report, but it tells you when another set of eyes is sensible. That keeps you from guessing at the scale of the problem.
Pre-1930 homes need a closer look, and that is true in Cardiff as much as anywhere else. A building survey is often the better choice for older terraces, listed buildings, timber-framed properties, heavily altered houses and homes with visible cracking or damp. It also suits buildings where you plan major renovation work, because hidden defects can affect the budget long before builders arrive. A quick mortgage valuation will not do that job.
We also recommend this level of inspection for unusual properties around Cardiff Bay and the city centre, especially if they have been converted, extended or refurbished more than once. Newer flats can still justify a full survey where there are waterproofing concerns, service issues or signs that the common parts have not been maintained well. If the building looks complex, the report should be too. That is where our surveyors add the most value.

Our building survey covers the visible fabric of the Cardiff property, from roof coverings and roof space to walls, floors, drainage, damp, timber and services. We also look at alterations, outbuildings and obvious defects that may affect repair costs. In a city with both Cardiff Bay apartments and older city centre terraces, that wider inspection gives a better picture than a short report. The result is a full written report in plain English.
A mortgage valuation is for the lender, not the buyer. It checks the property's value at a basic level and looks for obvious issues that could affect lending, but it does not analyse defects in the way a building survey does. If you are buying in Cardiff Bay, around the city centre, or in a terrace that has been extended, the difference can matter a great deal. The building survey gives you repair advice, condition ratings and next steps.
Most Cardiff inspections take 3-4 hours on site, depending on size, access and how complex the building is. A compact flat in Cardiff Bay is usually quicker than a large detached house or an older terrace with cellars, lofts and extensions. After the visit, we usually deliver the report within 5-10 working days. That gives time to review findings before exchange.
Our building survey in Cardiff starts from £400. The final fee depends on the size, age and type of property, so a flat in the city centre will usually cost less than a larger period house or a complex converted building. If access is awkward or the home has several additions, the inspection takes longer and the price can rise. The best approach is to get a quote matched to the property you are buying.
Yes, because it turns defects into facts. If our surveyors find roof wear, damp, damaged joinery or movement in a Cardiff terrace, you can speak to the seller with a clear repair estimate rather than a vague concern. That is useful in a market where homedata.co.uk records show 12,000 sales in the last twelve months and 44.4% of them were terraced homes. A report gives you a stronger position when the numbers do not stack up.
Not every new build needs a full building survey, but some still do. In Cardiff, new homes made up 1.4% of sales, or 166 transactions, and the average newly built property price was £397,000, so these are often substantial purchases. A new home may be better suited to a snagging check or a lighter survey unless there are signs of water ingress, poor finishes or warranty concerns. If the property is a conversion or has been altered heavily, a building survey can still be the right call.
A flat can still benefit from a building survey, especially where the block is older, conversions have been done or the balcony and waterproofing details look tired. Cardiff Bay has seen major change since the 1980s, and that mix of older and newer blocks means condition can vary from one building to the next. Our surveyors look at the visible parts that matter to a buyer, then spell out what needs attention. That is often enough to stop a small issue turning into a larger bill after completion.

Our building survey in Cardiff starts from £400, with the final fee based on the size, age and layout of the property. A compact flat in Cardiff Bay is usually less involved than a large detached house or a converted terrace near the city centre. Access also matters, because lofts, roof spaces and outbuildings can lengthen the visit. We quote against the actual home, not a one-size figure.
Older buildings often need more time, especially where there are extensions, timber issues or evidence of previous repair work. Newer homes can be quicker to inspect, but that does not mean they are free from defects, particularly in the city centre and around Cardiff Bay where recent development has changed the building mix. You usually receive the report within 5-10 working days, and that timing helps buyers act before contracts move forward. If you are buying in the Cardiff postcode area, a quote early in the process is the safest route.
