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.
We offer a new patio across Berkshire, and Windsor is one of the places we cover, along with nearby Slough, Egham and Staines. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in the South East it sits within £2,800–£6,200 including VAT.

What are homes like around Windsor?
Reading's Victorian terraces often show the town's patterned red and silver-grey brickwork, while Windsor, Maidenhead and Newbury mix Georgian, Victorian and Edwardian houses. Bracknell grew as a post-war new town with planned estates, Slough has a great deal of interwar and post-war housing, and newer developments sit on the edge of most towns.
Period terraces lend themselves to side-return extensions and dormer lofts; post-war and new-town homes often need replacement windows, roofline renewal and extra space. Larger detached houses commonly take on kitchen extensions, bifold doors and landscaping.
Building traditions across Berkshire also raise conservation and planning questions, so we check those for a new patio in Windsor at the survey stage.
Planning and building rules in Windsor
Windsor is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
A ground-level patio in a back garden does not usually need planning permission in England. Raised decks or platforms more than 30 cm high do.
Building Regulations do not normally apply to patios, but levels must stay below the damp-proof course and drain away from the house.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Free site survey
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a new patio.
Your fixed price
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new patio.
Dates and permissions
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Frequently asked questions
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Do you cover Slough, Egham and Staines?
Yes. As well as Windsor, we cover Slough, Egham and Staines and the rest of Berkshire. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
What should I do before the work starts?
Before work starts, clear garden furniture, pots and ornaments from the area and agree where materials will be delivered and stored. We need a route for wheelbarrows and, on larger jobs, a small digger, so let us know about side gates, narrow passages or access through the house. Tell us about any known drains, cables or pipes in the area.
What happens if my garden slopes?
A sloping garden can still have a level patio by cutting into the slope, building up with retaining walls, or creating terraces with steps between them. Retaining walls must be built to hold back the soil and allow drainage behind them. This adds cost but creates usable, level space. We look at the slope during the survey and suggest the most practical design.
How much does a new patio cost?
A typical 20m² patio in sandstone or porcelain costs £2,800–£6,200, including excavation, sub-base, laying and jointing. As a guide, allow roughly £100–£220 per square metre plus fixed costs for set-up and waste. Concrete slabs cost less, while slate, granite and large-format porcelain cost more. Steps, walls and drainage add to the total. We confirm a fixed price after the survey.
