Damp & Leak Detection in Horsham
Damp and leak detection identifies the underlying cause of damp patches, mould, musty smells or unexplained damage — whether that's rising damp, penetrating damp, condensation, or a hidden plumbing leak — before any repair work is recommended.
In Horsham, that covers Roffey, Holbrook, Littlehaven, Denne, Trafalgar, Broadbridge Heath, Southwater, Warnham, Colgate. Horsham's town centre retains a historic core of timber-framed and Georgian buildings around the Carfax and Causeway, surrounded by Victorian villas, interwar suburbs and newer developments on the town's edges. The surrounding villages and countryside sit close to the South Downs, which shapes both the property styles and the planning context for extension and renovation work.

Property styles in Horsham
Horsham has a strong stock of period cottages and Victorian villas in and around the town centre, alongside 20th-century family housing in the surrounding estates and larger detached homes in the outlying villages. Extension and loft conversion potential varies significantly between the historic core and the more recent suburbs.
Planning considerations
Horsham District Council is the local planning authority. The town centre, including the Causeway, is a conservation area with a number of listed buildings, meaning alterations to visible elevations, windows and materials are more tightly controlled. Some outlying villages also have their own conservation area designations, which we check before advising on likely planning routes.

Yes, we cover the RH12 and RH13 postcode areas in full, including Roffey, Holbrook, Littlehaven, Denne, Trafalgar, Broadbridge Heath, Southwater, Warnham, Colgate.
How do I know if it's damp or condensation?
Condensation typically appears on cold surfaces like windows and external walls, especially in bathrooms and kitchens, and varies with the seasons. Rising and penetrating damp tend to leave a more consistent, often tide-marked pattern. A proper diagnosis avoids guessing which one you're dealing with.
Can you find a hidden leak without lifting floors?
Often yes — leak detection equipment can trace many hidden leaks without invasive work, though some cases do need limited investigative opening-up to confirm the exact location before repair.
Is Horsham town centre a conservation area?
Yes, the historic core around the Carfax and Causeway is a conservation area with a number of listed buildings, which affects what changes can be made without planning permission or listed building consent.
