Homebuyer surveys tailored to Cardiff's terraces, bay-fronted Edwardian houses, and modern Bay apartments








Cardiff's housing stock spans everything from Victorian Pennant sandstone terraces in Canton and Splott to Edwardian bay-fronted houses across Roath and Pontcanna, through to modern apartments around Cardiff Bay. With an average house price of £268,000 and around 146,000 households across the capital, a RICS Level 2 Survey gives you a clear, structured assessment of visible defects before you commit to a purchase — flagging issues from damp penetration to roof defects using an easy-to-follow traffic-light rating system.

Cardiff may be the Welsh capital, but its residential streets are shaped by the coal export boom of the mid-nineteenth century. Between 1860 and 1914, house-building raced ahead and left thousands of workers' terraces in Splott, Grangetown, Adamsdown, and Canton, built from locally quarried Pennant sandstone with lime mortar joints, Welsh slate roofs, and minimal foundations. More than a century of weathering, Welsh rainfall, and in many cases badly judged modernisation has taken its toll. Our Level 2 survey checks those visible elements and flags trouble before it turns into an expensive surprise.
Green, amber, red. That is the condition rating system used in the Level 2 format, with green meaning no immediate concern, amber meaning repairs are needed but not urgent, and red meaning serious defects requiring attention. On a standard Cardiff terraced or semi-detached house in fair condition, the report looks at roofing, walls, windows, damp, drainage, and services. It sets out how serious each defect is and points to further investigation where needed, which can give us room to renegotiate the asking price if the survey finds bigger problems.
Cardiff falls under Natural Resources Wales, not the Environment Agency, so flood risk mapping, planning controls, and conservation area designations work a little differently from English cities. There are 27 conservation areas, including Cathedral Road, Pontcanna, and parts of Roath, where restrictions on external alterations apply. Our surveyors will record any conservation area status and flag planning points that could shape renovation plans or future maintenance duties.

Cardiff receives approximately 1,150 mm of rainfall per year — well above the UK average of 885 mm. Most of the city's Victorian and Edwardian terraces have solid Pennant sandstone walls without cavity insulation, making them especially vulnerable to penetrating damp. Low-lying areas around Grangetown and Riverside can also experience rising damp due to a high water table. If your Level 2 survey returns red ratings for damp in multiple rooms, your surveyor will recommend a specialist damp investigation. Treating widespread damp in a Cardiff terrace typically costs between £3,000 and £8,000 depending on the cause and extent.
Prices based on a standard 3-bed property. Cardiff pricing sits slightly below the national average, reflecting the Welsh property market. Larger or more complex properties will cost more.
The RICS surveyors we work with across Cardiff live and work here, so they know the difference between a well-kept Pontcanna terrace and a tired Cathays student rental. They can spot poorly repointed Pennant sandstone, and they understand how the city's river corridors affect individual properties. That local knowledge feeds into a report built around Cardiff's housing stock, rather than a generic checklist borrowed from somewhere else.

Enter the property details — address, type, rough age, and number of bedrooms. You'll receive a price straight away. If a Level 2 survey is suitable for the property, you can book and pay online. We contact the seller or their estate agent within 24 hours to arrange access.
A local RICS surveyor visits the property and carries out a full visual inspection. For a typical Cardiff terrace or semi-detached house — the most common types across the city — expect the visit to take 1.5 to 3 hours. Larger properties in areas like Cyncoed or Lisvane, or those with extensions and outbuildings, may take longer.
The completed Level 2 report arrives within 2 to 6 working days. It covers every inspected element with a condition rating, highlights urgent repairs, and recommends further investigation where needed. Our bookings team is available to talk through the findings and help you arrange any follow-up services such as a specialist damp survey or roof inspection.
The Level 2 format suits standard Cardiff properties built after 1900 that are in broadly fair condition — a typical Roath Edwardian semi or a post-war semi in Whitchurch, for example. If you are buying a pre-1900 terrace in Splott or Grangetown, a property with known structural issues, or a converted warehouse in Cardiff Bay, the more thorough Level 3 provides the deeper structural investigation you need. Unsure which to choose? Call our team and we can advise based on the property address and age.
Few British cities expanded as fast as Cardiff in the late Victorian period. By the early 1900s, the Bute Docks had turned a small market town into the world's largest coal-exporting port, and the population climbed from around 18,000 in 1851 to over 164,000 in 1901. That surge filled Splott, Adamsdown, and Grangetown with tightly packed Pennant sandstone terraces for dockers, steelworkers, and railway labourers, thrown up in a matter of decades. They tend to share solid walls, shallow strip foundations, rear extensions added informally, and lime mortar that has weathered unevenly over 120-plus years.
After the First World War, Cardiff spread north and west. Interwar semis in Whitchurch, Llanishen, and Rhiwbina brought cavity walls, wider plots, and integral garages, all with different risks from the inner-city terraces. Later, post-1960 estates in Pentwyn and Llanedeyrn introduced system-built construction and flat-roof designs, which bring their own maintenance headaches. The Level 2 report is set up to catch visible problems across every era, rating each building element so we can see at a glance what needs attention before, or soon after, purchase.

At just 0.14% of Cardiff's average property price, a Level 2 survey is one of the cheapest safeguards in a home purchase. It covers every visible part of the property and can pick up defects a viewing won't catch, such as cracked render hiding damp penetration, sagging roof timbers concealed by a loft conversion, or failing drainage behind a freshly landscaped garden. On a typical Cardiff terrace, even one amber-rated issue, say defective guttering at £800–£1,500 to repair or failing window seals at £1,000–£3,000 to replace, can give us grounds to renegotiate by more than the survey fee.
Leave the survey out, and the bill can rise fast. Replacing a Welsh slate roof on a Cardiff terrace runs £8,000–£14,000. Treating damp across the ground floor of a solid-walled Grangetown house costs £3,000–£8,000. Repointing an entire Pennant sandstone facade in lime mortar can reach £10,000–£15,000. This kind of survey will not find every hidden defect, because it is a visual inspection rather than a structural strip-down, but it will pick up the warning signs that lead to further investigation before completion.

Level 2 surveys in Cardiff start from around £380 for a standard 3-bed terraced or semi-detached house. Prices increase with property size and value — expect £500–£700 for larger homes in Cyncoed, Lisvane, or Radyr. Cardiff pricing sits slightly below the national average of around £395 because Welsh property values are lower than the English average. The exact cost depends on the number of bedrooms and the property's market value at the time of booking.
For a Victorian terrace in broadly fair condition — one that has not been heavily altered or extended, with no visible signs of structural distress — a Level 2 survey provides a useful overview of the property's condition. The traffic-light rating system highlights any areas of concern. If the surveyor finds indicators of deeper problems, such as significant cracking, major damp, or signs of movement, the report will recommend upgrading to a Level 3 investigation for those specific areas. Many buyers in Canton, Roath, and Pontcanna start with a Level 2 and only move to a Level 3 if the initial report raises red flags.
A Level 2 inspection on a standard Cardiff terraced house takes between 1.5 and 3 hours on site. Semi-detached and detached properties in the northern suburbs — Whitchurch, Llanishen, Heath — tend to be larger and may take up to 3.5 hours. The written report is produced within 2 to 6 working days after the inspection. Level 2 surveys are quicker than Level 3 because the surveyor does not open up the building fabric — it is a thorough visual inspection rather than an intrusive investigation.
The survey itself does not include a formal flood risk assessment, but your RICS surveyor will note any visible evidence of past water ingress, staining, or flood damage. Cardiff has the highest flood risk of any local authority area in the UK, with around 33,000 properties predicted to be at risk by 2050. Properties near the River Taff through Pontcanna, Riverside, and Canton, or near the River Ely through Caerau and Ely, face the greatest exposure. If the surveyor notes flood-related concerns, you can request a separate environmental search through your solicitor for detailed flood mapping data from Natural Resources Wales.
Damp is one of the most commonly flagged issues in Cardiff Level 2 reports. The city receives roughly 1,150 mm of rainfall annually, and many inner-city properties have solid Pennant sandstone walls that lack cavity insulation. The surveyor will use a handheld moisture meter on accessible walls and note any visible damp patches, mould, or staining. If damp readings are elevated across multiple rooms, the report will give a red or amber rating and recommend a specialist damp investigation. Penetrating damp through deteriorated mortar joints is especially common in Cardiff terraces built before 1919.
A Level 2 survey is well suited to most purpose-built Cardiff Bay apartments. These were largely constructed during the 1990s and 2000s Bay regeneration and use standard modern construction methods. The survey covers the apartment itself — walls, ceilings, floors, windows, and services — along with a brief assessment of visible common areas. If the apartment is inside a converted dock warehouse or industrial building, the construction is more complex, and a Level 3 may be more appropriate to assess how the conversion was carried out structurally.
Absolutely. The condition ratings in a Level 2 report give you documented evidence to present to the seller or their agent. If the report flags red-rated defects — a failing roof, significant damp, defective drainage — you can request a reduction in the asking price to cover the estimated repair cost. In Cardiff's market, where the average house price is £268,000, even a modest negotiation saving of £3,000–£5,000 vastly outweighs the survey fee. Your surveyor's findings carry professional weight that a verbal observation during a viewing does not.
A Level 2 survey is a visual inspection. The surveyor examines all accessible parts of the property and rates each element using a traffic-light system — green, amber, or red — with notes on the defect and what action to take. A Level 3 survey goes further: the surveyor opens up the building where possible, lifts floorboards, enters roof voids, and investigates defects to their source. For standard Cardiff homes in reasonable condition — a post-war semi in Whitchurch or a well-maintained Edwardian terrace in Penylan — a Level 2 gives you the information you need. For older properties with visible structural concerns, or buildings that have been significantly altered, the Level 3 is the right choice.
