Proper treatment means killing the lichen and algae first with a biocide, letting it work, then cleaning the dead growth away. It takes longer than a straight pressure wash but it's the only approach that actually lasts.
Black spot lichen and green algae spread fast across Indian sandstone, limestone and concrete flags, and once it takes hold a garden hose won't shift it. The dark speckling that starts in the shady corner of a patio in Silksworth creeps outward every wet spell, and by the time it reaches the seating area most of it is bonded into the stone rather than sitting on top.
Getting a patio treated and cleaned before the clocks change means it's ready for the first barbecue rather than still looking like it did in January. We can also advise on sealing at the same visit so it stays cleaner for longer through the next wet season.
Also Serving the Areas Around Silksworth
As well as Silksworth itself, we regularly work in Ryhope, Penshaw, Houghton-le-Spring and Sunderland and the immediate surrounding streets, so if you're arranging a clean for a relative or neighbour nearby, it's no extra trouble to quote for both.
Working a consistent local patch means we get to know the typical patio materials and conditions in the area, which helps us quote more accurately from the start.
Cost Per Square Metre
For larger or irregular areas it's often easier to think per square metre rather than a flat fee. Porous stone needing biocide treatment generally sits toward the higher end, while denser materials in good condition sit lower.
| Porcelain or concrete, light growth | from around £4-£5 per m² |
|---|---|
| Sandstone or limestone, moderate growth | around £5-£7 per m² |
| Heavy black spot lichen, any material | around £7-£9 per m² |
How We Clean Your Patio, Step by Step
We start with a walk round to check the material, the level of black spot lichen or algae, and anything unusual like loose pointing or an uneven flag. Then we apply a biocide treatment to any lichen, moss or algae and leave it to work - this is the step that actually kills the growth rather than just knocking it back.
Once the treatment has done its job we clean with steam or low-pressure washing depending on the surface, working the joints as well as the flag faces. Block paving usually gets re-sanding advice if the jointing sand has washed out, and we finish with a rinse and a check over before we leave.
Modern Estate Patios
Newer builds around Silksworth more often have Indian sandstone, porcelain or block paving laid within the last decade or two, usually with better drainage falls than older properties. That means less standing water, but black spot lichen can still establish quickly in shaded corners near fences and conifers.
Because the stone is younger, sealing is often a realistic option here - a treated, cleaned and sealed modern patio can stay looking close to new for several seasons if the joints and surface are in good condition to start with.
Patio Cleaning in Silksworth — common questions
A pressure-only clean might cost less upfront, but if the lichen's back within a couple of months you've paid for a result that didn't last. Treating properly first means the clean actually holds, which works out better value over a couple of years.
