A patio is a paved outdoor area next to the house or in the garden, laid in porcelain, natural stone or concrete slabs on a compacted sub-base and mortar bed, with falls that direct rainwater away from the house.
Blackwood sits within our coverage for a new patio, as do neighbouring Gelligaer, Risca and Caerphilly. Before giving a price we want to see the property: the condition of what's there now, the access, and anything that might need extra work. The guide range for Wales is £2,300–£5,100 including VAT, and your written quote will spell out exactly what that covers.

Homes in Mid Glamorgan
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
For a new patio in Blackwood, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Do you need permission in Blackwood?
Each UK nation sets its own consent rules, and Blackwood is in Wales. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
A ground-level patio does not usually need planning permission in Wales; raised platforms are more restricted.
Building Regulations do not normally apply, but levels and drainage must protect the house walls.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

On site to finish
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
What you can expect from us
Frequently asked questions
Does a patio need planning permission?
Most patios do not need planning permission, but it depends on the size, height and location, your home's position, whether it is listed or in a conservation area, and which UK nation you are in. Raised patios or decking more than a small height above the ground may need permission because of overlooking. We check the position for your garden before quoting.
How long does it take to lay a patio?
Laying a typical 20m² patio takes around three to five days, from excavation and sub-base to laying, jointing and cleaning. Larger or multi-level patios with steps and walls take longer. The mortar bed needs time to set, so light foot traffic is usually fine after a day or two and furniture can go on after about a week. We confirm timings with your quote.
How long will a new patio take?
On a typical home, allow 3–7 days on site. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
How do you make sure water drains away from the house?
A patio needs a gentle fall, usually a little over 1 in 80, so rainwater runs away from the house towards the garden, a drain or a soakaway. The surface should also sit well below the damp-proof course. If the patio meets a door threshold, a channel drain may be needed. We set levels with string lines and check falls as we lay each section.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
