What to know before a block paved patio in Watford
Across Watford, gardens range from narrow terrace plots to wide modern ones, and the best block, pattern and drainage choice changes with them.
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 patios service
Block suits patios that join a block drive or path, small or awkward spaces where large slabs would need too many cuts, and gardens where you want a pattern such as basketweave or a circle feature. We lay patios to fall away from the house and below the damp-proof course, with edging that stops the blocks creeping into the lawn.
- Jointing sand and compaction
- Blocks in your pattern, edges and cuts
- Layout marked out with you, including steps and doors
- Dig-out and compacted sub-base (around 100 mm for foot traffic)
- Falls away from the house and doors
What we check on a Watford survey
- Where rain will go: falls away from the house, onto lawn or borders, or into a channel
- Levels against the damp-proof course and door thresholds
- Block range, colour, pattern and border to suit the house
- Access for a mini-digger and how waste leaves the garden
- Trees and roots near the paving
Do you need permission for a block paved patio in Watford?
A patio or path behind the house does not usually need planning permission. Raised patios, listed buildings and flats can be different, so we check on the survey.
Paving in front of the house follows the front-garden rules: in England, a front drive over 5 m² needs planning permission unless it is permeable or drains to a lawn or border within your boundary.

Patios 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.
Do I need planning permission for a block paved patio in Watford?
Not usually for a patio or path behind the house. Raised patios, listed buildings and flats can be different, and paving in front of the house follows the front-garden rules. In England, a front drive over 5 m² needs planning permission unless it is permeable or drains to a lawn or border within your boundary.
How long does a block paved patio take?
Most patios and paths take two to five working days, depending on the size, any steps and the dig. Your quote gives the expected duration.
Can the paving be level with the back door?
Paving normally sits at least 150 mm below the damp-proof course. A level step-out needs a drainage channel against the house and careful detailing, which we agree on the survey.
