What Preservation Treatments does

Preservation Treatments is a UK-based specialist building preservation and remedial treatment contractor founded in 1972 and headquartered in Camberley, Surrey. The company delivers damp proofing (chemical DPC injection and salt-resistant replastering), structural waterproofing (Delta cavity drain membrane systems compliant with BS 8102:2022), structural repairs (Helifix Helibeam, HeliBar crack stitching, BowTie wall stabilization, and resin repairs), timber treatments (wet and dry rot eradication, woodworm control), and condensation solutions (Nuaire Positive Input Ventilation units, extract units, and Thermokote paint) to residential property owners, heritage organizations (English Heritage, National Trust), commercial property clients, local authorities, housing associations, and construction professionals (architects, surveyors, contractors) across South East England. Service delivery is anchored by CSRT-, CSSW-, and PCA WDS-qualified surveyors using Protimeter MMS2 moisture meters and thermal imaging for diagnosis.

The company operates a survey-first, project-based professional services model. Customers initiate contact through phone (multiple regional lines), online booking, or website enquiry forms; CSRT-qualified surveyors conduct on-site inspections and produce detailed reports and quotes; remedial works are then executed by in-house teams. Revenue is generated entirely through project-based fees with no disclosed pricing tiers, subscription, or recurring revenue model. Distribution is regional through offices in Camberley, Winchester, and London, supplemented by an SEO-led digital presence comprising extensive location-specific service pages across towns in London, Hampshire, Surrey, Berkshire, Sussex, and Kent. Insurance-backed guarantees are provided via Accelerant and QANW partnerships.

The company is privately held, family-owned, and has no disclosed venture capital, private equity, or institutional investor backing. It holds ISO 9001:2015, ISO 14001:2015, CHAS, Constructionline, Safecontractor, and Trustmark accreditations, is a PCA member contractor, and has won the Property Care Association Contractor of the Year award in both 2013 and 2024. The wholly-owned subsidiary Preservation Treatments (Surrey) Ltd (registered office in Leigh on Sea, Essex) supports regional operations.

Direct peers

• Peter Cox: One of the UK's most recognised damp proofing, timber treatment and structural waterproofing contractors with directly overlapping service lines to Preservation Treatments, including rising damp treatment, basement waterproofing, wet/dry rot and condensation solutions for residential and commercial clients.
• Timberwise: UK specialist in damp proofing, timber preservation (woodworm, wet and dry rot), basement waterproofing and condensation control. Direct competitor for PTL's residential preservation services with a similar survey-led model and PCA membership.
• Newton Waterproofing Systems: UK-based basement waterproofing specialist with both a products business and a network of approved contractors. Competes with PTL on structural waterproofing and supplies complementary membrane/sump technologies to the same specialist installer base.
• MacLennan Waterproofing: Specialist waterproofing contractor covering Type A, B and C systems including cavity drain membrane installations. Direct competitor to PTL's Delta-based basement waterproofing work and active within the same PCA-affiliated installer community.
• Wykamol Group: UK manufacturer and contractor specialising in damp proofing, basement waterproofing and structural repair systems. Comparable product breadth including DPC injection, cavity drain membranes and condensation solutions, overlapping both as a supplier and a contracting peer.

Others

• Helifix: Manufacturer of the Helibeam, HeliBar and BowTie structural repair systems used by PTL for crack stitching, cavity wall tie replacement and bulging wall stabilisation. Functions as PTL's partner technology provider and as an ecosystem anchor for the broader approved-installer base.
• Delta Membranes: UK manufacturer of cavity drain membrane waterproofing systems (Delta MS 500, FM, MS 20) and BS 8102:2022-compliant solutions. Acts as PTL's principal product supplier while also operating its own approved-installer network that includes competing contractors.
• Safeguard Europe: Manufacturer of damp proofing, basement waterproofing and structural repair products, including Natcem and other cementitious systems. Functions as an upstream supplier to PTL and as a competitor through its own approved-contractor network for similar remedial works.
• Basement Waterproofing Association members (e.g., Structural Repairs Ltd): Other BWA-registered waterproofing contractors and PCA members form a fragmented competitive set across the UK. Comparable in trade credentials and approved-installer access, though often more regionally focused and lacking PTL's heritage client roster.

Broad incumbents

• Rentokil Property Care: Rentokil's specialist property care division covers damp proofing, timber treatment and waterproofing across the UK, sitting within a much larger pest control and hygiene group. Operates nationally versus PTL's regional focus but competes for the same domestic and commercial remedial work.
