A replacement front or back door is a new door and frame, usually composite, uPVC or aluminium, made to fit your existing opening and fitted with multi-point locks and weather seals to improve security, warmth and kerb appeal.
We offer a new front or back door throughout Gwynedd, from Bangor, Gwynedd, Llandudno, Holyhead and Caernarfon to the smaller places in between. Each project starts with a free survey at your home and ends with a written figure, fixed for the work you choose. Because Gwynedd is in Wales, we work to the planning system and building standards used there, and guide prices for Wales run at £900–£3,200 including VAT.

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?
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Gwynedd comes under Wales, covered below, and we raise any questions with the council before your quote is finalised.
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.
How does the job run?
Free site survey
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
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
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
What you can expect from us
Questions about a new front or back door in Gwynedd
Can I have a low threshold for wheelchair or pushchair access?
A low threshold is a flat or very shallow sill that makes a doorway easier to cross with a wheelchair, walking frame or pushchair. Most composite, uPVC and aluminium doors can be supplied with one. The outside ground level and drainage need checking, because a low threshold must still keep rainwater out. We look at this during the survey and suggest a channel drain or small ramp if needed.
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.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
How secure are modern doors?
Modern external doors are far more secure than older designs because they lock at several points along the frame, not just at the handle. We fit anti-snap cylinders, which resist a common method of forced entry, in reinforced frames. Laminated or toughened glass panels add further protection. For extra peace of mind you can add a door chain, a viewer or a smart lock, which we can include in your quote.
