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.

Surface Science

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.

PSI Guide

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.

Most booked3,500 PSI

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.

Paint-safe1,500 PSI

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.

Commercial4,000 PSI

Commercial Facades

Office blocks and retail fronts accumulate diesel particulate and equatorial mildew. Scaffold-free facade cleaning with telescoping wands up to 4 storeys.

Hospitality2,500 PSI

Restaurant & Hotel Patios

Exposed aggregate, quarry tile, and natural stone patios need chemical pre-treatment before pressure — otherwise you're just redistributing the grease.

Specialist3,000 PSI

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.

Called at 8 AM, they were on site by 11. The driveway looks brand new. Genuinely shocked.

Our restaurant patio was embarrassing. Now it's the best-looking part of the property.
