Pressure washing in Carmarthen

Carmarthen is the county town and it's built on hills. There are tall Victorian and Edwardian townhouses in the middle, estates in Johnstown and Llangunnor, and bigger rural plots out towards Abergwili and Bronwydd.

Carmarthen is built on hills, so a lot of paths, steps and drives slope. Sloping hard surfaces stay wet longer and go slippery fast in winter, and cleaning the algae off makes a real difference to grip.

We set the pressure and distance for each surface rather than blasting everything the same, and we sweep up afterwards so the area is ready to use the same day.

Pressure washing Carmarthen FAQs

Carmarthen town and the villages around it, including Johnstown, Llangunnor, Abergwili, Bronwydd, Croesyceiliog, Llangain and Cwmffrwd. Anywhere in SA31, give us a ring.

Can you quote if I live away from my Carmarthen property?

Yes. We can quote from photos and a visit without you there, and send photos when the job is done. That's handy for rentals and inherited homes.

Yes, across Carmarthen (SA31) and nearby Johnstown, Llangunnor, Abergwili, Bronwydd, Croesyceiliog, Llangain and Cwmffrwd. Carmarthen is about twenty minutes up the A484 from Kidwelly.

Will pressure washing damage my patio?

Not when it's done properly. We adjust the pressure and distance for each surface and take more care with soft stone like sandstone.

Does block paving need re sanding afterwards?

Usually, yes. Washing lifts the old sand out with the dirt, so the joints should be topped up with kiln dried sand. We'll tell you if yours needs it.

When is the best time for pressure washing?

Spring and late summer are most popular, but hard surfaces can be washed any time it isn't freezing.
