Common questions.
Do you only work on houses?
No. We restore driveways, patios, render and windows for homeowners, and take on larger one-off exterior jobs for landlords, builders and property managers, from communal areas to sports courts.
Will pressure washing damage my surfaces?
We match the method to the surface. Hard surfaces like block paving get a controlled pressure wash, while render and painted walls get a gentle low-pressure soft wash that cleans without causing damage.
How much does exterior cleaning cost?
Every job is priced on size, surface and condition, so we give you a clear quote up front with no surprises. Use the form below and we'll get back to you, usually within one working day.
