Patio and driveway cleaning in Harpenden, Wheathampstead and St Albans
I clean, repoint and seal patios, driveways and paths across the Hertfordshire villages, then help you keep them that way. Send me a few photos on WhatsApp and I'll come back with a price.

What I do
Every job is priced from photos, done by me, and checked over properly before I leave.
Patio cleaning
Sandstone, slate, porcelain and concrete slabs brought back to their original colour.
Block paving and driveway cleaning
Moss, weeds and grime lifted out, then the joints re-sanded.
Patio and driveway sealing
Protects the surface so black spot, lichen and weeds struggle to come back.
Patio repointing
Crumbling, gappy or weedy joints raked out and repointed.
Decking cleaning
Green, slippery decking cleaned back so it is safe to walk on again.
Builders cleans for new builds
Brickwork and hard landscaping cleaned before handover, for builders and developers.
Recent work
Real jobs from local driveways and gardens, photographed before I started and when I finished.

AfterClean it once, then keep it that way
A freshly cleaned patio looks brand new, but left alone the black spot, lichen and weeds come back. Sealing after the clean protects the surface, so growth struggles to take hold in the first place.
It also changes what happens next year. A sealed surface is quicker for me to clean, so your yearly maintenance visit costs less, and your patio or driveway never gets back to the state it was in.

About Renaco
I'm Joel. I started this business as Jetmates and it's now Renaco: same person, same standards, with sealing, repointing and ongoing maintenance added to the cleaning.
Before this I worked as a quantity surveyor, so I'm used to pricing work properly and telling you upfront what it will cost. If your patio needs repairing rather than cleaning, I'll say so.
Common questions
How much does patio or driveway cleaning cost?
It depends on the size, the surface and how much growth there is, which is why I price from photos. Send a few on WhatsApp and you'll get a fixed price.
Will pressure washing damage my patio?
Not when it's done properly. I adjust the pressure and method to the surface, and take more care with softer stone and with pointing that is already loose.
How long will it stay clean?
That depends on shade, moisture and trees overhead. Unsealed, growth usually starts creeping back within a year or two. Sealing slows that down considerably, and a yearly maintenance clean keeps it looking new.
Do I need to be in?
No. I just need access to the area and an outside tap. I'll send you photos when it's finished.
