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.
A sealed surface is quicker and easier to clean, so your yearly maintenance visit costs a lot less: it doesn't need the heavy-duty clean an unsealed surface does.
Renaco is a registered Smartseal installer, so your patio or driveway is sealed with Smartseal's trade products, applied the way the manufacturer intends.

About Renaco
I'm Joel. I started this business in January 2026, aged 22, with one goal: to get the area I grew up in looking its best, and keep it that way.
Before this I worked as a quantity surveyor, so every quote is measured and priced properly, with no surprises. Renaco was formerly Jetmates, and is a registered Smartseal installer.
Common questions
How much does patio or driveway cleaning cost?
Every job is priced per square metre, and the rate depends on the surface and how much growth there is. Send a few photos on WhatsApp for a rough estimate, and after a free survey you'll get a fixed price.
Will pressure washing damage my patio?
Not when it's done properly. We 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. If you're in, we'll walk round it together before we leave. If not, we'll send you photos when it's finished.
