Nairobi's surfaces fight dust, diesel, and rain every day. We fight back.

Before & after.
Every time.
Real jobs, real Nairobi addresses, real surfaces. Drag the slider to see what industrial pressure does.
“I genuinely didn't know the driveway was that colour. It looked like a different house. The estate agent said it added 10% to the asking price — I believe it.”

Homeowner, prepping for sale
Why Nairobi's red dust stains differently
Nairobi sits on volcanic laterite soil — iron-rich, fine-grained, and deeply penetrating. Unlike coastal salt deposits that sit on the surface, laterite particles bond chemically with concrete pores. Standard garden hoses push it deeper. Industrial cold-water pressure at 3,000–4,000 PSI lifts it out from the root. That's the difference between wiping a surface and actually cleaning it.
“Three tenants had complained about the walkways in six months. After Blast came in on a Saturday, not a single complaint since. The building looks like it was just built.”
David Ochieng
Office Park Manager
Not all surfaces take the same pressure
Painted boundary walls need 1,200–1,500 PSI or the paint strips. Exposed aggregate can handle 2,500 PSI without dislodging stone. Commercial concrete parking decks get the full 4,000 PSI treatment with a rotating nozzle. Every job starts with a surface assessment — we match the machine to the material, not the other way around.
“Customers kept asking if we'd renovated. We hadn't — Blast just removed five years of grime in four hours. The patio photos on our Instagram now actually look like somewhere you'd want to eat.”

Surface Guide
We clean every surface
on your property.
Different materials need different pressures. Here's exactly what we do, and why.
Concrete Driveways
Iron-rich laterite bonds into porous concrete over months. At 3,500 PSI with a rotating nozzle, we lift years of staining in a single pass — revealing the original aggregate colour.
Perimeter Walls
Painted walls need 1,200–1,500 PSI — enough to strip grime, not paint. Unpainted block gets the full 2,500 PSI fan nozzle treatment.
Commercial Facades
Office blocks and retail fronts accumulate diesel particulate and equatorial mildew. Scaffold-free facade cleaning with telescoping wands up to 4 storeys.
Restaurant & Hotel Patios
Exposed aggregate, quarry tile, and natural stone patios need chemical pre-treatment before pressure — otherwise you're just redistributing the grease.
Rooftop Decks & Parking
Waterproofing membranes need low-pressure hot water cleaning. Painted parking lines and oil stains on bare concrete require degreaser + 3,000 PSI cold water.
