What affects the cost of home render cleaning?
- Render area (m²) — priced per square metre; a small elevation costs much less than a full four-sided detached house.
- Render type — K-Rend, Monocouche, silicone, pebble-dash and spar-dash each need slightly different biocide and technique.
- Soiling level — light green algae is a single visit; thick lichen or black staining may need two stages.
- Height & access — ground-floor and standard 2-storey cleans are straightforward; very tall Victorian houses may need MEWP access.
- Landscaping protection — sheeting valuable plants and outdoor furniture takes a little extra time on heavily planted sites.
- Add-ons — cleaning soffits, fascias, rendered garden walls, or rendered outbuildings is often combined at a discounted rate.

Frequently asked questions
How much does home render cleaning cost in the UK?
Expect £99–£195 for a single elevation, £195–£350 for a small semi or terrace, and £350–£850 for a full detached house depending on size and soiling.
Is soft-wash render cleaning safe for K-Rend?
Yes — soft-wash with biodegradable biocide is the manufacturer-recommended method for K-Rend and Monocouche. No pressure washing, no scrubbing, no colour damage.
Will the biocide damage my plants or lawn?
No — at working concentration the biodegradable biocide is safe around plants, pets and lawns. We also sheet sensitive borders and water landscaping after a clean if needed.
How long will the clean last?
A proper soft-wash biocide treatment typically keeps algae and black staining at bay for 2–4 years. Shaded north-facing walls or homes near woodland re-grow faster and may need a refresh at year 2–3.
Do I need to be home during the clean?
Not essential — but it helps to chat through any sensitive areas (planters, water butts, garden ornaments) before we start. We’ll message before arrival and send photos when done.
How long does a full-house render clean take?
Most homes are completed in a single day. Very large detached properties or heavily soiled render may need two days — we’ll tell you during the survey.
Can you clean rendered walls plus fascias, soffits and windows at the same time?
Yes — combining render, fascias/soffits and window cleaning into one visit usually saves 15–25% vs booking each separately.
Are you insured?
Yes — full public liability insurance. Certificate available on request.
