Block paved patios in Treharris: the local picture
Around Treharris, gardens are often larger, so falls, steps and where the water goes need planning.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.
How much does a block paved patio cost in Treharris?
Most block paved patio quotes in Wales fall within £75–£130 per m² including VAT. A 20 m² patio would usually be about £1,700–£3,000, with any extras listed separately on your quote.

What is included?
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.
- Dig-out and compacted sub-base (around 100 mm for foot traffic)
- Optional sealer
- Falls away from the house and doors
- Layout marked out with you, including steps and doors
- Blocks in your pattern, edges and cuts
What we check on a Treharris survey
- Manhole and inspection covers in the area
- Ground conditions and how deep the dig must be
- Steps, walls and changes of level
- Block range, colour, pattern and border to suit the house
- Where rain will go: falls away from the house, onto lawn or borders, or into a channel
Do you need permission for a block paved patio in Treharris?
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 Wales, new front paving should be permeable or drain within your boundary to avoid planning permission, and drives of 100 m² or more need SuDS approval.

Patios in Treharris: questions
What happens to my old patio or lawn?
Old slabs, concrete or turf are dug out and taken away, listed as its own line on your quote.
Is the survey in Treharris free?
Yes, for new paving here: the survey and written quote are free with no obligation. Repairs and cleaning are usually priced from photos, or from a short visit where needed.
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.
