Patio Cleaning & Black Spot Lichen Removal in Roker
Black spot lichen on your patio in Roker? We treat it properly, then clean - sandstone, limestone, porcelain, concrete and block paving all covered here.
For patios around Roker that means sandstone and limestone get treated gently enough to protect the pointing, while block paving and concrete flags that can handle more get a proper deep clean including the joints, not just the flag faces.
Patio cleaning prices in Roker 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.
The honest answer is that pressure washing on its own won't solve it long-term. Lichen has a root structure that grips into sandstone and limestone, so it needs a biocide treatment to kill it off before any cleaning happens, otherwise it's back within months.

1960s and 70s Estate Patios
Patios from this era in Roker 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.
Add-On Services and Sealing
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.
What We Do (and What We Deliberately Don't)
We do treat black spot lichen and algae with a proper biocide before cleaning. We do adjust pressure and method to the actual material - sandstone and limestone get different handling to porcelain or concrete block paving. We do check pointing and flag stability before we start.
We don't run a pressure washer straight over lichen without treating it first. We don't use one blanket pressure setting for every surface. And we don't seal a patio that hasn't fully dried out or that has failing pointing that needs sorting first - we'll flag that honestly rather than seal over a problem.
