Diagnose what your property needs

Answer a few quick questions and we'll arrange a specialist visit — no obligation, no charge.

Step 1 of 7

First, who's enquiring?

Everything under one specialist roof

One trusted team for every damp, mould & timber problem

From rising damp and penetrating water ingress to black mould, woodworm, roofing leaks and energy efficiency, our specialists diagnose the true cause and deliver a lasting fix. Explore each service below, or book a complimentary survey and we'll tell you exactly what your property needs.

Damp Proofing

Keep your home dry and protected with specialist damp proofing for rising damp, penetrating damp and water ingress. We carry out a full property survey to trace exactly where moisture is coming from, then recommend the right treatment — a new damp proof course (DPC), our Proofterior Dry System (PDS) membrane and re-plaster, or targeted repairs to stop water entering the wall. This prevents damaged plaster, musty smells, salt staining and long-term structural problems.

Timber Treatment & Restoration

When damp reaches your timbers, fast action matters. Our timber treatment protects joists, floors, roof timbers and structural wood from wet rot, dry rot and woodworm. We identify the underlying moisture source, treat or replace the affected timber, and advise on prevention so the structure of your property stays strong, safe and dry for the long term.

Mould Removal & Air Quality

Professional mould removal and prevention for homes suffering from black mould, recurring condensation or poor ventilation. We treat affected surfaces with anti-microbial products and, crucially, resolve the underlying cause — excess humidity, cold spots or airflow problems. The result is a healthier home, improved indoor air quality and a far lower risk of mould returning.

Black Mould RemediationIndoor Air QualityPositive Input Ventilation (PIV)

Condensation & Ventilation

Condensation forms when warm, moisture-laden air meets a cold surface — typically on windows, external walls and poorly ventilated rooms. It is the leading cause of surface mould and damp-feeling rooms. We reduce humidity and raise surface temperatures with Positive Input Ventilation (PIV), passive air vents and internal insulation to break the condensation-mould cycle for good.

Roofing Repairs & Upgrades

Roof defects lead to leaks, damp patches and costly internal damage. Our roofing repairs and upgrades stop water getting into your property by addressing damaged coverings, weak points around chimneys and weathered flashings. We also repair and replace rainwater goods — gutters and downpipes — to direct water safely away from your walls and foundations.

Energy Efficiency Upgrades

Cold, poorly insulated walls increase condensation risk and push up heating bills. Our energy efficiency upgrades raise internal surface temperatures and cut heat loss with internal wall insulation (ISO-THERM), breathable masonry water-repellent creams, specialist wall paints and loft insulation — improving comfort, reducing damp risk and lowering running costs.

Structural & Water Damage

From water-damaged plaster and finishes to failed mortar joints and eroded brickwork, our structural and water damage services put your property back to a sound, weather-tight condition. We carry out re-plastering following damp works, repointing and brickwork repairs, and install air bricks and subfloor ventilation to protect suspended timber floors.

Property Preservation

Property preservation protects the materials your home is built from before problems start. We use breathable, compatible materials, including masonry water-repellent cream, lime and matched-mortar repointing, timber preservatives and protective roof coatings, to shield brick, stone, timber and roofs from weather and decay, keeping your property sound and valuable for decades.

Survey & Diagnostic Services

Every lasting solution starts with an accurate diagnosis. Our specialist surveyors use professional moisture-testing equipment to confirm the true cause of damp, mould or timber decay before any work is recommended. You receive a clear, honest written report with practical recommendations — the foundation of getting the treatment right first time.
