Horsham’s historic core around the Carfax and Causeway features sandstone and rendered period buildings that call for gentle, low-pressure methods, alongside modern retail parks and offices off the A24 that need regular traffic-film removal. Render and roofs on the newer estates of Roffey, Southwater and Broadbridge Heath are prone to north-side algae, which our softwash treatments lift and inhibit for longer.

Horsham cleaning — frequently asked questions

Do you cover commercial and office premises in Horsham?
Yes - we work with offices, retail units, managed blocks and commercial premises right across the borough, as well as private homes.
Are you fully insured and do you provide RAMS and COSHH?
Yes - we are fully insured and supply method statements, risk assessments (RAMS) and COSHH documentation for every commercial job as standard.
How do I get a quote?
Call 0800 644 6161, message us on WhatsApp, or request a free quote online - we will arrange a free, no-obligation site survey and a clear written price.
How much does exterior cleaning cost in Horsham?
Every property is different, so we price from a free site survey rather than a flat rate. You receive benchmarked, clearly itemised pricing in writing before any work starts - with no obligation and no hidden extras.
Can you clean on a regular schedule or contract?
Yes - many of our Horsham commercial clients are on scheduled maintenance plans, from regular office window cleaning to quarterly gutter clearing and annual render or roof cleans. One-off cleans are welcome too.
How quickly can you attend a property in Horsham?
We can usually arrange a free site survey within a few working days anywhere across RH12 to RH13, and we prioritise urgent problems such as overflowing gutters or storm damage.
Are your operatives trained for safe work at height?
Yes - all work is carried out by trained operatives under full risk assessments (RAMS), using safe work-at-height methods such as water-fed poles and access platforms where needed.
How often should exterior cleaning be done?
It depends on the surface and your surroundings. As a general guide for Horsham properties: window cleaning every 4 to 8 weeks, gutter clearing once or twice a year, and render, roof and pressure washing once or twice a year. Properties near trees or busy roads, and those in damp, shaded spots, usually need more frequent visits. We will recommend a sensible schedule during your free survey.
What cleaning methods do you use?
We match the method to the surface. Windows and cladding are cleaned with pure water-fed poles for a streak-free finish and safe reach at height. Gutters are cleared with high-reach vacuum systems. Render, roofs and other delicate surfaces are treated with a low-pressure softwash and biocide rather than high-pressure jetting, which removes algae, moss and lichen at the root without damaging the surface. Hard surfaces such as driveways and forecourts are restored with commercial pressure washing.
Which areas of Horsham do you cover?
We cover the whole town and surrounding areas, including Roffey, Southwater, Holbrook, Denne, Trafalgar, Faygate, Warnham, Broadbridge Heath and Rusper, across all RH12 to RH13 postcodes. If you are just outside Horsham, get in touch - we work right across the wider West Sussex area.
