Patio Cleaning in Coundon — the finished patio after a full clean, on a DL14 property

Trusted Patio Cleaning in Coundon and the Surrounding Area

Fully insured patio cleaning in Coundon. Biocide trained, spill management trained, honest pricing. Decking and fencing add-ons available on request too.

The figure that actually matters is cost per year of clean patio, not the invoice total - a treated and sealed patio can stay looking good for two or three seasons, while a quick pressure-only wash can green up again within months.

We treat, clean and can seal patios across Coundon - sandstone, limestone, porcelain, concrete flags and block paving all covered, with a biocide treatment for black spot lichen and moss before any washing starts.

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.

What Actually Moves the Price

Sealing, re-sanding of block paving joints and re-pointing advice are usually priced separately from the base clean, since they depend on the condition we find once the surface is clean and dry.

Large patio (30-50m²)typically £280-£450
Heavy lichen/algae surchargeoften an extra £20-£60
Sandstone or limestone, moderate growtharound £5-£7 per m²
Heavy black spot lichen, any materialaround £7-£9 per m²

Block Paving

  • Block paving needs the joints treated as much as the block faces - jointing sand harbours moss and weed growth that spreads algae staining across the whole surface if left. We clean the gaps as a distinct step, not just an afterthought.
  • Where jointing sand has washed out or gone green and compacted, we can advise on re-sanding once cleaning is done, which helps stop the same growth coming straight back.

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.

Patio Cleaning in Coundon — common questions

Treat first, clean second - that's how we get black spot lichen off patios in Coundon for good rather than for a few weeks. Fully insured, biocide trained, and happy to advise on sealing and decking or fencing add-ons at the same visit.

We're upfront about pricing from the start, so there's no surprise cost for doing it right.

Get Your Patio Looking Its Best Again

A biocide treatment followed by the right clean for your material costs a bit more upfront than a straight pressure wash, but it lasts years longer. We'll explain exactly what your patio needs and why.
