Planning a block paving sealing job in Watford
Watford has everything from short terrace frontages to wide drives on newer estates, so the survey sets the layout and the dig.
Clay soils are common in parts of the East of England, so drainage and sub-base depth get extra attention.

What you get with our sealing service
Sealing only works on paving that has been cleaned and re-sanded first and is completely dry, so it is usually part of a clean, re-sand and seal package. It is not permanent: most sealers need renewing every three to seven years as they wear in the wheel tracks, and new paving should be left for a few months before sealing so moisture and any white efflorescence can clear.
- Drying time and a date when cars can return
- Second coat where the product requires it
- Sealer applied evenly by roller or low-pressure sprayer
- Check that the paving is clean, re-sanded and dry
- Edges, walls and doors protected

Sealing in Watford: questions
Do you cover Bushey, North Watford and Rickmansworth?
Yes. We cover Watford and the places around it, including Bushey, North Watford and Rickmansworth, and the rest of Hertfordshire.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
How often should block paving in Watford be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
Will cleaning damage my block paving?
Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
