Chepstow's older properties and natural stone driveways need specialist care — not a domestic pressure washer. We use professional surface cleaners and SH treatments to remove years of moss, lichen, and black spot from your block paving, natural stone, and concrete, without damaging a single slab.
Before
After
Properties in Chepstow, Sedbury, and Tutshill often feature natural sandstone, slate, and traditional block paving — surfaces that are easily damaged by inexperienced operators. We visit every property to assess the surface type before choosing the right pressure, cleaning agent, and technique. The result is a deep clean that lasts, not a botched wash that strips your pointing or leaves tide marks.
Black Spot & Lichen Removal
SH chemical treatment kills biological growth at the root — not just washed off to return in weeks.
Safe on Natural Stone & Sandstone
Pressure adjusted per surface — we never risk etching or cracking older Chepstow stonework.
Detailed Edge & Wall Work
We clean right to the edges and walls so there are no dirty borders left behind.
The same rigorous approach we use on every job across Chepstow and South East Wales.
We start with a professional high-pressure wash using flat-surface cleaners that spin evenly across your driveway or patio. This removes the primary layers of moss, algae, and loose grime without the striping marks a domestic lance leaves behind.
This is the step most cleaners skip. We apply a professional Sodium Hypochlorite (SH) treatment that kills the biological spores responsible for black spot lichen and recurring algae. Without this step, moss and lichen return within months — with it, your surfaces stay clean far longer.
Once the SH treatment has neutralised all organic growth, we give the whole area a thorough clean rinse. This removes all residue, leaving your driveway, path, or patio completely clean and safe to walk on — for your family and your pets.
For block paving driveways, we can return once the surface is bone-dry to brush in fresh kiln-dried sand. This stabilises the blocks, locks in the joint, and gives that crisp "as-new" finish.
Yes, when done correctly. Many properties in Chepstow and Sedbury have sandstone or natural slate surfaces that require lower pressure and careful technique. We always assess the surface material before starting and adjust our equipment accordingly — so there's no risk of etching, cracking, or stripping the pointing.
Not if we treat it properly. Our SH chemical treatment kills the biological root of moss and lichen — not just the visible surface layer. This means results last significantly longer than a pure pressure wash alone. Properties we clean typically stay clear for one to two growing seasons.
Because price depends on the exact surface area, condition, and material, we always visit the property before quoting. For most Chepstow addresses, Cam can arrange a quick site visit and get a precise written quote back to you the same day. WhatsApp is the fastest way to get started — often within 30 minutes.
