Our Approach

An ethical approach to every undertaking

Surveyor on site representing professional ethics and standards.
01

Ethics

We are regulated by the Royal Institution of Chartered Surveyors and professional ethics are central to our ethos.

Surveying and inspection work that reflects efficient professional practice.
02

Efficiency

As an RICS Tech Partner we build surveying software, including in-house tools that shorten the gap between site inspection and issued report.

Detailed building inspection image representing transparency and integrity.
03

Integrity

Advice is given against the lease and the evidence on site, not against the outcome a client prefers. Where a defect is overstated or outside tenant liability, we say so in writing.

Property survey image used to represent sustainability and responsible project delivery.
04

Sustainability

Inspection routes are planned to limit site visits. Reports are delivered digitally and reuse photographs and CAD data already gathered for the survey.

Where Roof Design Meets Condensation Risk

Two timber-framed roof lanterns formed part of a recent external inspection we undertook on a mansard roof in West London. Both featured single glazed elements, limited overhangs, and decorative paint finishes in poor condition.

The presence of condensation to internal glazing, along with signs of historical repair and timber exposure, highlights a common set of issues—particularly in traditional or poorly detailed roof structures.

Where single glazed rooflights are retained in occupied spaces, internal dampness is frequently the result of thermal bridging or trapped moisture, rather than rainwater penetration alone.

In such cases, replacement offers the opportunity to introduce modern, thermally efficient materials and more robust junction detailing—reducing risk and improving long-term performance.

About Cottenham Park

Cottenham Park

Cottenham Park sits in the London Borough of Merton in south-west London, between Raynes Park and Wimbledon, a predominantly residential area defined by substantial inter-war semi-detached and detached housing on generous plots across streets such as Cottenham Park Road, Queensmere Road, and the surrounding suburban grid. The building stock is dominated by 1920s and 1930s semi-detached and detached houses in mock-Tudor, neo-Georgian, and standard suburban styles, with integral or attached garages, rendered or pebble-dashed upper storeys, and characteristic bay-window detailing. Smaller pockets of Edwardian and Victorian stock survive on older routes, with occasional post-war infill and some larger apartment-led schemes at the edges. Surveying instructions in Cottenham Park commonly include pre-purchase surveys on inter-war family houses, schedules of condition for residential lettings, party wall advice for loft conversions and rear extensions, and defect assessments on inter-war stock reaching the end of its original construction-life cycle.

Inter-War Housing and Construction Issues

The characteristic Cottenham Park house is a substantial two-storey inter-war semi-detached or detached property with cavity brick walls (often with rendered or pebble-dashed upper storey), concrete or clay tile roofs, timber suspended ground floors, and bay windows. Common survey findings include corroding original cavity wall ties — typically mild steel — causing horizontal cracking to outer brickwork leaves, concrete tile roof coverings at or past their serviceable life, failed or bridged damp-proof courses, ageing original drainage in salt-glazed clay, and cracking or detachment in rendered and pebble-dashed finishes. Mock-Tudor timber detailing and rendered detailing are typical defect locations where water ingress and decay concentrate.

Extensions, Loft Conversions, and Party Walls

Loft conversions, rear extensions, and side infills are widespread as families seek more space from the substantial but original inter-war housing. Party wall advice under the Party Wall etc. Act 1996 is routine. Schedules of condition on neighbouring properties before notifiable works begin, party wall awards, and monitoring during construction are standard. Pre-purchase surveys on already-extended properties need to assess extension quality — flat-roof performance, junction detailing, structural provision at removed loadbearing walls, and differential settlement between new and older shallow foundations. Verification that Building Regulation and party wall consents were obtained is an important area of reporting.

Trees, Clay, and Subsidence

Cottenham Park's London clay subsoil, combined with substantial mature street and garden trees on generous plots, makes subsidence and heave a recurring survey issue on the shallow-founded inter-war stock. Pre-purchase surveys frequently identify movement cracking, and the surveyor's role is to assess whether cracking is stable or progressive, whether nearby trees or drainage defects are drivers, and whether further investigation — CCTV drainage surveys, arboricultural advice, or level monitoring — is required. Where properties have been underpinned, surveyor review of the records — extent of underpinning, structural engineer's specifications, completion certificates, and insurance implications — is an important part of purchase due diligence.
