Wall removal is taking out an internal wall to open up rooms; where the wall is load-bearing, a steel beam sized by a structural engineer is installed on padstones to carry the weight above, with the work approved by building control.

Homeowners in Caernarfon usually consider removing a wall for one of a few reasons: something has worn out, the house no longer suits the way they live, or they are getting it ready to sell. We visit, agree a specification and put a fixed price in writing. Most jobs like this take 1–3 weeks including making good, and we work across Gwynedd, including Bangor, Gwynedd, Holyhead and Llandudno.

What are homes like around 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.

If your house in Caernarfon fits one of these patterns, it helps us anticipate what removing a wall will involve, though we always confirm the details on site.

Planning and building rules 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.

Removing an internal wall does not need planning permission in Wales unless the building is listed.

Load-bearing walls need Building Regulations approval and structural calculations; the Party Wall etc. Act 1996 applies to shared walls.

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

  1. We look at the job

    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.

  2. Your fixed price

    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 removing a wall.

  3. Getting ready

    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.

  4. On site to finish

    Our trades complete removing a wall while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.

What you can expect from us

Changes agreed in writingIf something needs to change once work is under way, we explain why and confirm the cost or saving in writing before carrying on.
Clear staged paymentsThe quote sets out when each payment falls due, linked to stages of the work, so you know in advance what is owed and when.
Plain-English adviceWe explain options, materials and trade-offs without jargon, so you can make decisions about your home with a clear picture of what each choice means.
Realistic timetablesWe give you an honest estimate of time on site at the quote stage and keep you informed if anything affects the programme once work starts.

Questions about removing a wall in Caernarfon

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 disruptive is removing a wall?

Removing a wall is dusty and noisy, but the most disruptive part is short, usually one to three days for propping, demolition and installing the steel. We seal doorways with dust screens, protect floors and keep a safe route through the house. Making good, plastering and floor repairs follow over the next week or two. Most people stay at home throughout.

How long will removing a wall take?

On a typical home, allow 1–3 weeks including making good. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.

How much does it cost to remove a load-bearing wall?

Removing a load-bearing wall of about 3–4m with a steel beam typically costs £2,800–£7,400, including structural calculations, building control and making good. A non-load-bearing partition costs much less. As a rough guide, allow around £600–£1,600 per metre of opening plus fixed costs for the engineer, approvals and propping. Wider openings, posts and flush beams cost more. We confirm a fixed price after the survey.

Can I have a beam that does not show?

A flush or hidden beam sits within the depth of the ceiling so there is no visible downstand, giving a clean, open look. It is possible where the floor joists can be connected into the side of the beam, which takes more steel and labour. It costs more than a standard beam below the ceiling. The engineer confirms whether it suits your house.
