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.
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.
In Caernarfon, as elsewhere in Gwynedd, we take the building's age and construction into account before recommending anything, because both can change what is involved in a new front or back door.
Do you need permission in Caernarfon?
Because Caernarfon falls under Wales's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
In Wales, replacing windows and doors on a house usually needs no planning permission if the new ones are similar in appearance. Listed buildings, flats and some conservation areas are controlled, so the council should be asked first.
Building Regulations in Wales apply to replacement windows and doors, covering energy performance, ventilation and escape routes. A registered competent person can self-certify the work, or building control inspects it.
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
A visit to your home
A free survey comes first. It gives us what we need to price a new front or back door 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.
Getting ready
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.
On site to finish
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Front and back doors in Caernarfon: questions
How long will my home be open while the door is fitted?
Fitting a new door usually takes half a day to a full day, and your home is only open for the short time between taking out the old frame and fixing the new one. We keep the opening covered if there is any delay, and we never leave a doorway insecure overnight. Once the frame is fixed, we hang the door, adjust the locks, seal around the frame and finish the trims.
What is the difference between a composite and a uPVC door?
A composite door has a tough outer skin over a solid insulated core, so it feels heavier and more solid than uPVC and holds its colour well. A uPVC door is built from reinforced plastic panels and costs less. Both can have multi-point locking and good weather seals. Many people choose composite for the front door and uPVC for back or side doors, where looks matter less.
How much does a new front door cost?
A new front door costs £900–£3,200 supplied and fitted, depending on the material, the amount of glass and whether you want side panels. A uPVC back door sits at the lower end, a composite front door in the middle, and aluminium doors or doors with side panels at the top. Locks, letterplates and dual colours also affect the figure. We confirm a fixed price in writing after measuring your opening.
How much will a new front or back door cost in Caernarfon?
As a guide, expect to pay £900–£3,200 including VAT for a new front or back door 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.
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 a new front or back door, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
