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.

At our recent commercial due diligence survey of an industrial unit in East London the findings of our report led to significant financial advantages for our client. We identified several issues which equated to potential cost savings of approximately £150,000.

These findings played a pivotal role in empowering our client during lease negotiations. With the evidence provided by us, our client was able to engage confidently and effectively in discussions with the landlord. This not only facilitated a reconsideration of the lease terms but also allowed the client to negotiate a reduction in rental values and improvements to other lease-related conditions.

Our proactive approach in highlighting these issues underscores our commitment to adding tangible value to our clients' investment decisions.

By ensuring that all factors are thoroughly vetted, we position our clients in a place of strength, enabling them to make informed and advantageous decisions and negotiations.

Cost Saving
We identified issues that give rise to cost savings that equate to circa £150,000. The issues that we identified were used by the client/tenant to reconsider the lease for the property. 
In addition to this the defects that were identified allowed the client to negotiate with the landlord with regard to the rental value of the property, and other lease terms.

When Flat Roof Coverings Diverge from Standard Practice

We recently carried out a drone-based roof condition inspection in West London, where an unusual bituminous liquid-applied membrane had been installed over a zinc flat roof.

This type of overlay—reinforced with a textile mesh—is not typically encountered in applications of this kind, where polymeric systems are more commonly specified. In this case, surface discolouration, exposed reinforcement mesh, and evidence of ponding all raised concerns regarding durability and workmanship.

When flat roofing systems deviate from established detailing or product specifications, there is increased risk of premature failure—particularly when installation records or manufacturer compliance documentation are unavailable.

Early identification through external inspection can assist in defining appropriate next steps, including testing or sampling to determine whether remedial works or full replacement is required.
Roof Risk Without Internal Access

We are often instructed to assess external roof coverings where internal access is restricted. A recent case in W14 illustrates the value of high-level drone inspection for identifying latent structural concerns from the outside.

Numerous depressions in the flat roof deck suggested potential hidden deterioration of the substrate, likely linked to historical water ingress. In the absence of internal inspection, we recommended core sampling to confirm the extent of any concealed damage and to inform the appropriate scope of remedial work.

External-only inspections, when carried out systematically, can yield sufficient evidence to justify further investigation, particularly where the risk of ongoing deterioration to concealed timber or insulation is suspected.

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.

At our recent commercial due diligence survey of an industrial unit in East London, we utilised drone technology to conduct a detailed inspection of areas otherwise impossible to access, such as the roof, cladding, and high-level windows. Our surveyors, who are also fully qualified drone pilots, are registered with the Civil Aviation Authority. This ensures compliance with the highest standards of safety, particularly in urban environments where airspace restrictions are prevalent.

The drone survey captured high-resolution images and data of the relevant areas, allowing us to identify key issues that might otherwise have been missed. Specifically, we discovered significant defects in the roof and cladding, along with issues in the rainwater goods. Such findings are crucial as they hold the potential to save our client significant expenditure, mitigating risks that could escalate into costly repairs if left unaddressed.

Our ability to integrate drone technology into traditional surveying practices not only elevates the thoroughness of our inspections but also adds substantial value to our clients by providing more comprehensive insights. This case in East London is a prime example of how leveraging innovative technology can lead to advantageous outcomes for our clients, ensuring their investments are sound, and their properties are maintained to the highest standard.

DRONE SURVEY
A drone survey was undertaken which enabled a detailed inspection of the roof, cladding, and high level windows. All of our surveyors are fully qualified drone pilots and registered with the Civil Aviation Authority to fly camera drones subject to local airspace restrictions. For this survey were were able to determine significant roof defects, cladding defects, and problems with the rainwater goods that had the potential to save the client tens of thousands of pounds.

About Colindale

Colindale

Colindale sits in the London Borough of Barnet in north-west London, a predominantly residential area reshaped by extensive inter-war suburban development along the Edgware Road and a substantial recent wave of large-scale apartment-led regeneration at Beaufort Park, Colindale Gardens, and the former Hendon Aerodrome site. The building stock includes inter-war semi-detached and terraced housing across the streets around Colindale station, pockets of post-war council housing, retained institutional buildings including the former Colindale Hospital and the Metropolitan Police estate, and substantial recent delivery of mid- and high-rise apartment blocks. Typical building types include 1930s cavity-walled semi-detached housing, post-war estate blocks of varied construction, and large-scale new-build apartment developments. Surveying instructions in Colindale commonly include pre-purchase surveys on inter-war houses and new apartments, EWS1 and fire safety assessments on recent apartment buildings, schedules of condition for residential lettings, and party wall advice for extensions and new-build adjacencies.

Inter-War Housing

The inter-war semi-detached and terraced housing that dominates the older core of Colindale presents cavity-brick walls, often with rendered or pebble-dashed upper storeys, concrete or clay tile roofs, timber suspended ground floors, and bay windows. Common survey findings include corroding mild-steel cavity wall ties causing horizontal cracking to outer 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 finishes. London clay subsoil combined with mature street trees makes subsidence a recurring theme on the shallow-founded inter-war stock, with movement cracking regularly identified and underpinning records requiring review.

New Apartment Development and Building Safety Act

Colindale has been one of the most heavily developed areas of outer north-west London, with Beaufort Park, Colindale Gardens, and a series of adjoining schemes delivering large volumes of apartment stock. New-build blocks are typically steel- or concrete-framed with rain-screen cladding, podium construction over retail and car parking, and communal mechanical ventilation and district-heating systems. Following the Building Safety Act and Grenfell-related remediation programmes, EWS1 assessments, fire risk appraisals, and advice on cladding remediation are routine pre-purchase and ongoing management-stage instructions. Early-life defects in balcony detailing, podium waterproofing, and communal services feature prominently.

Service Charges, Leasehold, and Party Walls

Pre-purchase advice on new-build leasehold flats in Colindale routinely addresses service-charge adequacy, sinking-fund provision, and the landlord's planned major-works programme. Where cladding remediation is outstanding or in progress, valuation, mortgageability, and remediation-cost liability significantly affect transaction outcomes. Loft conversions and rear extensions across the older inter-war stock generate routine party wall work under the Party Wall etc. Act 1996, and party wall obligations also arise where new apartment construction adjoins existing residential or commercial stock. Schedules of condition on neighbouring properties before notifiable works begin and monitoring during construction are standard.
