Block paving sealing in Letchworth Garden City: the local picture
In Letchworth Garden City, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

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.
- Sealer applied evenly by roller or low-pressure sprayer
- Edges, walls and doors protected
- Check that the paving is clean, re-sanded and dry
- Drying time and a date when cars can return
- Second coat where the product requires it

Sealing in Letchworth Garden City: questions
How often should block paving in Letchworth Garden City be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
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.
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.
