Horsham drainage and leak detection.

St Leonard's Forest sits at the northern edge of a district that spans from the medieval market streets of Horsham town centre out through Billingshurst, Storrington and Pulborough to the greensand ridges of rural West Sussex. That spread – dense period terraces in RH12, a mix of inter-war and modern stock in RH13, and scattered agricultural properties in RH14 – means the drainage and pipe infrastructure across the district is genuinely varied, and a single approach rarely fits every job.

Property stock and water supply

Period properties around Horsham town centre frequently retain original cast-iron soil stacks, laid when Christ's Hospital was already a local landmark and long before anyone considered the maintenance implications. Southern Water supplies the district with hard water at 280 to 310 ppm CaCO3 – enough sustained calcium carbonate loading to accelerate limescale build-up inside pipework and to exacerbate joint failure where iron has already begun to pit. Rural properties in Billingshurst, Pulborough and Storrington often sit off the mains drainage network entirely, relying on private soakaways whose condition can be unknown for years.

How we work in Horsham

247 Rapid Response covers RH12, RH13 and RH14 for two services: drainage investigation and clearance, and leak detection. All visits are booked project-grade – scheduled one to two working days ahead with a confirmed 9 am to 5 pm on-site slot, so your site contact or managing agent knows exactly when we will arrive. There is no callout fee; the fixed price is agreed after the survey. See /pricing for the full schedule.

We do not carry out emergency reactive callouts in this area. Every Horsham visit is a planned, methodical survey backed by written results.
