Bring concrete flags back to life in Wetherby
Chalky staining, moss and pigment fade on precast concrete slabs.
The classic LS22 enquiry is a 1990s rear-garden patio that's gone patchy grey-and-buff because the last cleaner walked a rotary too close.
We work Wetherby and the surrounding LS22 postcodes every week, so a Concrete flag paving job here is a scheduled call, not a special trip.
