Cladding is a protective outer layer of boards or panels, such as timber, composite, fibre cement or uPVC, fixed to battens on the outside of a wall to change its appearance, shed rain and, where insulation is added, reduce heat loss.
Across Gwynedd, people look into cladding 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 £4,600–£11,000, VAT included, in Wales, and every quote follows a free visit.

Housing across 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?
Homes in Gwynedd come under the regulations for Wales, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
In Wales, rendering or cladding may need planning permission in conservation areas, and listed buildings need consent.
Building Regulations in Wales can require insulation upgrades when a large part of an external wall is renovated.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
We look at the job
A free survey comes first. It gives us what we need to price cladding properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
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 cladding.
Booking the work
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Gwynedd property.
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.
How we work
Frequently asked questions
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.
Can cladding improve insulation?
Cladding can improve insulation if insulation boards are fixed to the wall behind the battens, which reduces heat loss and can help with cold or damp internal walls. This adds thickness, so window reveals, sills and roof edges need careful detailing. Cladding alone, without insulation, adds very little warmth. We can price both options so you can compare.
How much does house cladding cost?
Cladding around 40–60m² of wall, such as an extension or upper storey, costs £4,600–£11,000, including membrane, battens and trims. As a guide, allow roughly £80–£180 per square metre plus fixed costs for scaffolding and set-up. uPVC and softwood sit at the lower end, while hardwood, composite and fibre cement cost more. Adding insulation increases the price. We confirm a fixed figure after the survey.
How long does cladding take to install?
Cladding a small dormer or gable usually takes a few days, an extension or upper storey around one to two weeks, and a whole house two to three weeks or more. Scaffolding, insulation and detailing around many windows add time. Timber boards may need to acclimatise on site first. We give you a programme with the written quote.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from cladding, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
