Merthyr Tydfil is a town of hills, terraces and big boundary trees, and all of that shapes what happens to garden surfaces. Shade, leaf drop and steady rain leave decking green, patios slick and paths dark. Our power washing service cleans decking, patios, paths, steps, driveways, block paving and walls, restoring their appearance and making them easier to use safely.
We choose pressure to suit each material, because timber, concrete and stone are all different. Plants and doors are covered, and loose debris is cleared before washing starts. We also cover Dowlais, Treharris, Troedyrhiw and Pontsticill, so if you are on the edges of town, get in touch and tell us what needs cleaning.

Large boundary trees are a feature of many Merthyr Tydfil gardens, and they bring shade, dripping branches and a constant supply of leaves, seeds and twigs. Damp organic matter sits on decking boards and patio slabs, feeds algae and leaves brown stains behind. In a hillside garden that gets little afternoon sun, the problem can return quickly if it is left untouched.
The first step is to sweep and clear everything loose, including the gaps between boards and slabs. Then we wash, working along the grain on timber and in even passes on stone and concrete. Taking this approach lifts the stains rather than driving them further in, and it leaves a more even, natural-looking surface than a rushed blast would. Patience pays off on shaded timber.

Timber decking in Merthyr Tydfil is often the surface that suffers most in a damp valley climate. It becomes slippery and grey, and heavy-handed washing can raise the grain or leave furry splinters. We use a gentler setting, keep the nozzle at a sensible distance and follow the boards, so the wood is cleaned without being damaged. Where the boards are already rotten or loose, we will say so plainly.
After cleaning, decking can be left to dry and then treated with a stain or oil of your choosing if you want to protect it. We do not push that on anyone. For stone patios and concrete, a firmer wash and, if wanted, re-sanding and sealing can follow. Whatever the surface, we will talk through the choices before we begin. The decision is always yours.
Tell us about the surfaces you want cleaned, roughly how large they are and whether there are steps or sloping sections to deal with. A photo of the worst areas is useful. We will say what we think is sensible, agree the work with you, and then tackle it carefully, so your Merthyr Tydfil garden is clean, tidy and ready to be used again.

Most South Wales patios need a proper clean about once a year, though shade, damp and nearby trees can mean more often or a little less.

There is no single perfect month for every tree, but winter suits many species, and this guide shows how timing, nesting birds and weather affect the choice.
Read the guide →Yes, with the right approach. We use lower pressure, work along the grain and keep a steady distance. If boards are soft or rotten, we will tell you first, because washing can make weak timber worse. Our aim is to clean it, not strip it.
Shade, hillside rain and falling leaves all keep patios damp, and algae thrives on damp stone. Sweeping regularly, trimming back overhanging growth where possible and sealing after cleaning can all slow it down, though some regrowth over time is normal.
Yes, loose leaves, twigs and moss are brushed away first so they do not block drains or get pushed into joints. It is a small step but it makes the wash more effective and the finish much cleaner around the edges of your garden.
