The job, explained

What driveway cleaning & sealing involves

Driveways take a beating from weather, traffic and oil drips, and over time moss and black spots make the whole front of your home look tired. We deep clean block paving, concrete, tarmac and natural stone, then re-sand and seal where needed so the finish lasts and stays easier to look after.

Good to know

Common questions.

Do you reseal block paving after cleaning?

Yes. We can re-sand the joints and apply a protective sealant that helps lock the sand in, slow down weed growth and keep the colour looking fresh. Just ask for it in your quote.

Will the pressure washer damage my driveway?

We set the pressure to suit the surface, so block paving, concrete and stone each get the right treatment. Softer surfaces are cleaned more gently to avoid pitting or marks.
