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.

Office premises inspected during a dilapidations instruction, representing advice given on the evidence.
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.

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 Harrow

Harrow

Harrow sits in the London Borough of Harrow in north-west London, a substantial suburban district encompassing Harrow town centre, Harrow on the Hill, North Harrow, South Harrow, and West Harrow. The building stock is defined by exceptional Tudor and Georgian stock around Harrow on the Hill and the historic Harrow School estate, extensive inter-war semi-detached and detached development across Metroland streets built between the wars, post-war council and private infill, and recent apartment-led regeneration around Harrow town centre and the station. Typical building types include listed Tudor and Georgian stock in Harrow on the Hill, late-Victorian and Edwardian terraces on the central fringes, extensive inter-war semi-detached and detached houses, post-war estate blocks, and recent mid- and high-rise apartment developments. Surveying instructions in Harrow commonly include pre-purchase surveys on inter-war stock and period houses, EWS1 assessments on recent apartment blocks, schedule-of-condition and dilapidations work on retail and office leases in the town centre, and party wall advice for widespread extensions.

Harrow on the Hill and Listed Stock

The Harrow on the Hill Conservation Area contains exceptional Tudor, Georgian, and Victorian stock, much of it listed, including buildings associated with Harrow School. Pre-purchase surveys at this level require detailed assessment: hand-made brick and timber-framed structures, clay-tile and slate roof condition, timber sash and leaded casement windows, lower-ground moisture management, and the cumulative impact of successive refurbishments. Listed building consent and conservation area controls constrain external alteration and affect repair specification throughout.

Inter-War Metroland Housing

The majority of Harrow's residential stock is inter-war semi-detached and detached housing built along the Metropolitan Line corridor between the 1920s and 1930s. Cavity walls in facing brick, hipped clay-tile roofs, timber casement or steel Crittall windows, and large back gardens are characteristic. Common survey findings include wall-tie corrosion in exposed elevations, original window deterioration, flat-roof failures on original garage and rear additions, chimney breast removal detailing, and original drainage reaching the end of its life. Loft conversions, rear extensions, and side infills are widespread, generating routine party wall work under the Party Wall etc. Act 1996.

Town Centre Regeneration and Commercial Leases

Ongoing apartment-led regeneration around Harrow town centre and the station has delivered substantial new mid- and high-rise apartment stock. New-build blocks are typically steel- or concrete-framed with rain-screen cladding, podium construction, and communal mechanical services. Following the Building Safety Act, EWS1 assessments, fire risk appraisals, and cladding-remediation advice are routine pre-purchase and management-stage instructions. Retail, restaurant, and office stock in the town centre generates schedule-of-condition, dilapidations, and licence-to-alter work, with the St George's Centre and surrounding streets supporting substantial commercial lease activity.
