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.
From a first conversation about a new patio to the day the site is cleared, homeowners in Caernarfon deal with us directly. We come out to measure up at no cost, explain the choices in plain terms and send a written quote. For context, comparable work in Wales usually falls within £2,300–£5,100 including VAT, and it is available across LL55.

Building in Caernarfon
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.
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.
Building traditions across Gwynedd also raise conservation and planning questions, so we check those for a new patio in Caernarfon at the survey stage.
Permissions for a new patio in Caernarfon
As Caernarfon 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.
What happens after you get in touch?
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new patio so the price reflects your home.
Quote in writing
After the survey we send a quote for a new patio that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
The work itself
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.
How we work
Common questions
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.
How do I clean and look after my patio?
Most patios just need regular sweeping and an occasional wash with water and a mild patio cleaner. Porcelain is the easiest to keep clean. Natural stone benefits from a sealant to reduce staining and from prompt cleaning of spills like oil or wine. Re-point any joints that crack or wash out. Avoid high-pressure jet washing close to joints, which can damage them.
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.
How much will a new patio cost in Caernarfon?
As a guide, expect to pay £2,300–£5,100 including VAT for a new patio in Caernarfon. That range is adjusted for Wales, which runs about 8% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
Do you cover Bangor, Gwynedd, Holyhead and Llandudno?
Yes. As well as Caernarfon, we cover Bangor, Gwynedd, Holyhead and Llandudno and the rest of Gwynedd. 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.
