Harrow has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Many London streets have controlled parking and narrow frontages, so we measure the car space and the crossover before anything else.

What does a block paving sealing job involve?
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.
- Second coat where the product requires it
- Drying time and a date when cars can return
