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.
Across Gwynedd, people look into a new patio to replace something worn out, to make the house work better for them, or to get it ready for a sale. We cover Bangor, Gwynedd, Llandudno, Holyhead and Caernarfon and the smaller towns around them, working to the rules that apply in Wales. Expect a guide of £2,300–£5,100, VAT included, in Wales, and every quote follows a free visit.

Homes in Gwynedd
Slate defines much of Gwynedd, from quarrying villages such as Bethesda and Blaenau Ffestiniog with their stone terraces to slate roofs across the county. Bangor and Caernarfon have Victorian and Georgian streets, Anglesey has stone cottages and bungalows, and resorts such as Pwllheli and Barmouth have Victorian terraces and newer bungalows.
Stone and slate homes need breathable lime render and pointing, and slate roofs often need careful repair rather than replacement. Terraces suit loft conversions, and bungalows commonly take extensions and window upgrades.
Eryri (Snowdonia) is among the wettest areas in the UK, and exposed coasts take strong wind and salt, so render and roof details need to be robust.
Do you need permission in Gwynedd?
As Gwynedd is in Wales, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
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.
How does the job run?
Survey and measure
A free survey comes first. It gives us what we need to price a new patio properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Your fixed price
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Booking the work
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
The work itself
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.
How we work
Questions about a new patio in Gwynedd
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.
Is porcelain or sandstone better for a patio?
Porcelain is dense, stain-resistant and stays looking clean with little care, making it a good choice if you want a modern, low-maintenance patio. Indian sandstone has natural colour variation and a softer, traditional look, and costs a little less, but it can stain and weather over time and benefits from sealing. Both make durable patios when properly laid. We bring samples to the survey.
Which postcodes in Gwynedd do you cover?
We cover LL57, LL30, LL65 and LL55, along with the rest of Gwynedd. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
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 you combine a new patio with other work?
Yes. Because we manage several trades under one contract, we can plan a new patio alongside other work on your Gwynedd home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
