Services
Damp Proofing
Our damp proofing specialists address rising damp and lateral damp penetration using chemical injections and physical barriers. With ISO 9001-certified processes, we install damp proof courses that comply with BS8102:2009 standards. Each solution includes comprehensive diagnostics, aqueous preservatives with one-hour re-entry, and 10-year GPI-backed guarantees, ensuring long-term protection against moisture ingress in residential and commercial properties.
Basement Waterproofing
We specialise in structural waterproofing and cavity drain membrane systems for basement conversions. Our BWA-certified technicians implement tanking solutions and Delta membrane systems that withstand hydrostatic pressure. Services include humidity control, drainage channel installation, and insulation integration, transforming subterranean spaces into habitable areas while maintaining Building Regulation compliance across London and Surrey properties.
Dry Rot Treatment
Our PCA-certified surveyors identify and eradicate dry rot (Serpula lacrymans) through targeted chemical treatments and structural repairs. We replace decayed timbers following FIRA guidelines, apply boron-based preservatives, and implement ventilation improvements. The process includes moisture mapping diagnostics and comes with transferable guarantees, addressing both active infestations and preventing future outbreaks in period and modern properties.
Condensation Control
We resolve condensation issues through humidity monitoring, ventilation system installation, and thermal imaging diagnostics. Our solutions include mechanical ventilation with heat recovery (MVHR) systems, thermal insulation upgrades, and property-specific behavioural guidance. The service addresses mould growth patterns while maintaining indoor air quality standards, particularly in Victorian and listed buildings across the South East.
Property Maintenance
Our comprehensive property maintenance covers cavity wall tie replacement, brick stitching, and structural repairs. With 50+ years' experience, we address cracks from subsidence, install helical reinforcements, and perform pointing repairs using lime-based mortars for heritage buildings. Services include diagnostic surveys, dilapidation assessments, and scheduled maintenance programmes for residential blocks and commercial premises in London's conservation areas.
