Black Spot Lichen Treatment & Patio Cleaning, Fulwell

Sandstone, limestone, porcelain, concrete or block paving - we clean patios properly in Fulwell, treating black spot lichen at the root, not the surface.

City of Sunderland · SR6 · 5.7 miles east of our Washington base

Patio cleaning prices in Fulwell typically run from around £4-£8 per square metre depending on material, condition and how much black spot lichen treatment is needed, with most standard-sized patios coming in as a fixed quote rather than an hourly rate.

Why does a patio in Fulwell go black in patches even when the rest of it looks fine? Nine times out of ten it's black spot lichen, not dirt, and it favours the shaded, damp corners of a garden - under trees, behind fences, on the north-facing side of the house.

Homeowners

Part of a Wider Garden Makeover

If a patio clean is one piece of a bigger garden project - new planting, a re-laid lawn, or a fresh fence - we're happy to fit around the rest of the work and time the clean so it's not undone by other trades traipsing across it afterwards.

We can also advise on sealing at this stage if the patio's being cleaned as part of a wider tidy-up, since it's the easiest point to protect a freshly cleaned surface before everything else gets finished.

Coastal Exposure and Salt-Laden Air

Being roughly 0 miles from the coast, patios around Fulwell pick up salt-laden air alongside the usual rain, which speeds up algae growth and can accelerate wear on softer stone like sandstone and some concrete finishes.

The combination of salt spray and damp sea air means these patios often need cleaning slightly more often than inland gardens, and sealing becomes more worthwhile as a way of protecting the surface between cleans.

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.

Clean-and-Seal Process, from Treatment to Protection

  1. 1

    Assess suitability for sealing

    We check the stone and pointing are in good enough condition to seal - sealing over failing joints just traps the problem.

  2. 2

    Biocide treatment

    Lichen, moss and algae are treated and left to work before any cleaning begins.

  3. 3

    Deep clean

    Steam or pressure cleaning removes dead growth and ingrained dirt, matched to the material.

  4. 4

    Full dry-out period

    The patio needs to dry out properly before sealing - we won't seal a damp surface as it traps moisture underneath.

  5. 5

    Sealant application

    A suitable sealer is applied evenly across the surface to protect against future staining and slow new growth.

  6. 6

    Cure and handover

    We explain the curing time before the patio can be walked on or have furniture put back, and leave care advice for the months ahead.
