Black Spot Lichen Treatment & Patio Cleaning, Brandon
Trusted patio cleaning in Brandon covering sandstone, limestone, porcelain, concrete flags and block paving. Honest advice on sealing and re-pointing too.
Whether it's a small courtyard patio behind a terrace, a large sandstone patio on a newer estate, or a block-paved driveway-turned-patio, the cleaning approach in Brandon starts with the same question - what's it actually made of, and how bad is the black spot lichen.
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.
Call Trevor on 07501 060609 for a straightforward quote. We're fully insured, biocide trained, and happy to give honest advice on re-pointing or sealing even if it's not something we end up doing ourselves.
Typical Patio Cleaning Costs
Prices vary with size, material and how established the black spot lichen or algae is, but most standard residential patios in Brandon fall into the ranges below. These are guide figures - we'll always confirm a fixed price after seeing the patio.
| Small patio (up to 15m²) | typically £80-£150 |
|---|---|
| Medium patio (15-30m²) | typically £150-£280 |
| Large patio (30-50m²) | typically £280-£450 |
| Heavy lichen/algae surcharge | often an extra £20-£60 |
Matching the Method to the Material
Indian sandstone and limestone are porous and can be relatively soft, so they get treated with a biocide, left to work, then cleaned with steam or low-pressure washing to protect the surface and the pointing around each flag.
Porcelain is dense and far more resistant, so it can generally take a firmer clean, though we still watch the joints. Concrete flags and block paving sit in between - solid enough for a proper wash, but we check for spalling or loose bedding sand before going in, and clean joints separately where block paving has gone green between the blocks.
Handling a Patio with Mixed Materials
- 1
Map the materials
Many gardens combine sandstone, block paving and concrete edging - we identify each zone before starting so methods can differ across the same patio.
- 2
Treat by zone
Biocide strength and dwell time are adjusted per material rather than applied uniformly across the whole area.
- 3
Clean by zone
Porous stone gets gentler steam or low-pressure cleaning; denser porcelain or concrete can take a firmer wash where needed.
- 4
Blend the finish
We finish with an overall rinse so the different zones read as one consistent, even-coloured patio rather than a patchwork.

New Homeowners Inheriting an Old Patio
Moving into a property with a patio you didn't lay yourself often means inheriting someone else's neglect - years of black spot lichen, unknown pointing condition, or a material you're not sure how to look after. We'll tell you honestly what it's made of and what it needs.
That includes flagging anything beyond cleaning, like joints that need re-pointing, before we start, so you're not surprised by an issue a wash uncovers rather than causes.
1960s and 70s Estate Patios
Patios from this era in Brandon are often concrete flags or early paving slabs, laid directly onto sand or hardcore with minimal drainage falls built in. Over fifty-plus years the surface has usually absorbed a lot of green algae and moss into a slightly rougher, more porous finish than newer materials.
These older concrete flags can be more prone to surface crazing, so we test pressure carefully rather than assuming they'll take the same clean as modern slabs.
