Plumbing, Heating & Air Conditioning in Horsham

Emergency plumbing in Horsham — 24/7 rapid response

Burst pipes, failed valves, leaking cylinders and boilers that die overnight do not wait for office hours. Our Horsham emergency line is answered 24 hours a day, seven days a week, including weekends and bank holidays, and you speak to an engineer rather than a call centre.

In the older Causeway and Denne Road properties we often find original lead or steel pipework behind plaster, so we come prepared to isolate, cap and make safe before any chasing out begins.

First job is always to make the property safe — isolate the water at the stopcock, stop the leak spreading and protect floors and ceilings. Then we diagnose properly and give you a fixed price to put it right, so there is no open-ended hourly bill while water is still coming through the ceiling.

• Burst and leaking pipework, including hidden leaks under floors
• No heating or hot water call-outs
• Failed stopcocks, ballvalves, cylinders and immersion heaters
• Overflowing tanks, blocked and backing-up waste pipes
• Make-safe first, fixed price second — never an open-ended clock

Boiler installation and servicing in Horsham

We install, service and repair Worcester Bosch, Vaillant and Glow-worm boilers, and we hold spares and manufacturer accreditation for the models most commonly fitted in Horsham homes. Whether you are replacing a tired 15-year-old system boiler or moving to a modern combi to free up an airing cupboard, we survey the property first, size the boiler to the radiators and hot water demand, and quote a fixed price with no moving goalposts.

Hard water around Horsham leaves scale in cylinders and combi plate heat exchangers, and the older estates in Roffey frequently have systems heavy with magnetite sludge.

That is why we recommend a power flush or a thorough chemical clean on most Horsham boiler replacements. Fitting a new boiler onto a system full of scale and magnetite is the fastest way to kill it — a proper flush, a good magnetic filter and the correct inhibitor dose protect both the boiler and your warranty. Annual servicing then keeps that warranty valid and catches worn parts before they strand you in January.

Residential air conditioning in Horsham

Our air conditioning work is residential only, and every installation is carried out by F-Gas certified engineers. We design and fit wall-mounted split systems and multi-split systems from Samsung, Daikin and Worcester Bosch, sized to the room rather than sold from a catalogue, so bedrooms in Horsham stay comfortable through a July heatwave without a noisy unit running flat out all night.

A typical install is a single indoor unit paired with a discreet outdoor condenser, with pipework routed and boxed in as neatly as possible — something that matters as much in a listed cottage as in a new build. Multi-split systems let us run several rooms from one outdoor unit, which is usually the tidiest and best-value option for a whole-house project.

We also service existing systems: filter cleaning, condensate drain checks, refrigerant pressure testing and leak checks. Regular servicing keeps efficiency up, stops the classic indoor drip caused by a blocked condensate drain, and keeps running costs down.

• F-Gas certified design, installation and servicing
• Samsung, Daikin and Worcester Bosch split and multi-split systems
• Discreet pipework and careful siting of outdoor condensers
• Filter, drain and refrigerant servicing for existing systems
• Residential work only — homes, annexes and home offices

Everyday plumbing and heating work across Horsham

Alongside the big installations, most of our Horsham diary is everyday plumbing: leaking taps and toilets, replacement radiators and thermostatic valves, unvented cylinder installation and servicing, outside taps, bathroom and en-suite pipework, and smart heating controls such as Hive, Nest and Tado.

We turn up when we say we will, protect floors, and clear up before we leave. If a repair is not worth doing, we will tell you straight rather than sell you a part that buys three months.
