Professional Damp & Timber Services Across Doncaster

Damp Proofing & Rising Damp Treatment

Rising damp affects thousands of Doncaster properties, causing damage to plaster, decorations, and structural timbers. Our PCA qualified specialists diagnose the cause of damp problems accurately—whether rising damp, penetrating damp, condensation, or a combination—then provide the correct remedial treatment.

We install chemical damp proof courses (DPC injection), treat affected walls, remove contaminated plaster, apply specialist waterproof render systems, and fully re-plaster to proper heights (not just halfway up the wall like some contractors). Our damp proofing work comes with long-term guarantees, protecting your Doncaster property for years to come.

PCA Qualified Damp & Timber Surveys

Accurate diagnosis is essential for effective damp treatment. Our PCA qualified surveyors conduct thorough damp and timber surveys throughout Doncaster and South Yorkshire, using professional moisture meters, thermal imaging, and expert inspection to identify the exact cause and extent of damp problems.

We provide comprehensive written reports detailing our findings, recommended treatments, and clear quotations. Our surveys cover rising damp assessment, penetrating damp investigation, condensation and mould surveys, timber decay inspection (dry rot, wet rot), woodworm infestation checks, and pre-purchase property surveys for homebuyers.

Dry Rot & Wet Rot Treatment

Timber decay from dry rot or wet rot causes serious structural damage if left untreated. HPS Damp Proofing specializes in fungal decay treatment across Doncaster properties, from Victorian terraces to modern homes. Our timber preservation service includes identifying the moisture source causing decay, removing affected timbers and surrounding masonry, treating remaining timbers with fungicidal preservatives, replacing structural timbers with pre-treated alternatives, and eliminating the conditions that allowed fungal growth.

Dry rot (Serpula lacrymans) spreads rapidly through properties and requires specialist treatment. Our 17 years’ experience handling South Yorkshire timber decay ensures proper eradication and prevention of recurrence.

Woodworm Treatment & Timber Preservation

Woodworm infestation weakens floor joists, roof timbers, and structural woodwork throughout Doncaster properties. We identify woodworm species (Common Furniture Beetle, Deathwatch Beetle, House Longhorn Beetle), assess structural damage severity, treat timbers with professional insecticidal preservatives, and replace severely damaged structural members when necessary.

Our timber preservation work protects your property’s structural integrity with guaranteed treatments and proper remedial carpentry.

Basement Waterproofing & Conversions

HPS Damp Proofing provides specialist basement waterproofing throughout Doncaster and South Yorkshire. Whether you’re converting a damp cellar into habitable space or need to protect existing basements from water ingress, we install Type A tanking systems (waterproof membranes), Type B systems (cementitious waterproofing), and Type C cavity drain membrane systems.

Our basement specialists design waterproofing solutions tailored to your property’s specific conditions, with proper sump pump systems, ventilation, and guarantees on all waterproofing installations.

Condensation, Mould & PIV Systems

Condensation and mould growth affect health and damage properties throughout Doncaster. Our mould eradication service uses specialist equipment to eliminate airborne mould spores and surface growth, treating the root cause rather than just cleaning visible mould.

We install Positive Input Ventilation (PIV) units that prevent condensation by providing gentle, filtered airflow throughout properties—the most effective long-term solution for condensation problems. PIV systems dramatically reduce mould growth, improve air quality, and eliminate musty odors.
