Decking goes green and slippery over winter as algae builds up in the grain. We clean it carefully with water alone, lifting the grime and making it safe to walk on again - without tearing up or furring the timber.

What we clean
Composite decking is cleaned gently so the finish isn't marked, and timber is cleaned in a way that keeps the boards smooth rather than raised and splintery.
It comes up looking fresh and, more importantly, far less slippery.
Why book Hydro
Mark quotes it, cleans it and answers the phone. No call centre, no subbies.
We adjust the pressure and technique for timber, hardwood and composite decking, lifting algae and embedded dirt without needlessly raising the grain or marking the finish.
We lift the slippery surface build-up and dirt trapped in the boards, leaving the decking cleaner, safer underfoot and ready for any treatment or finish you choose to arrange separately.
A fixed price up front, fully insured, and you pay the same day once you've seen it finished. 10/10 on Checkatrade.
No - we soften the pressure and technique for timber so the boards are cleaned without furring or splintering. Composite is cleaned gently too.
Yes. Composite is cleaned with water alone at a gentle pressure so the finish stays intact.
