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.

What are homes like around Castlereagh?
County Down takes in suburbs of Belfast, Bangor and Holywood with Victorian and Edwardian villas, and Newry, Downpatrick and Banbridge with older town centres and newer estates. Mourne granite appears in buildings around the mountains, and detached rural homes and bungalows are common across the county, often rendered or pebbledashed.
Villas and semis suit kitchen extensions, loft conversions and garden landscaping. Rural detached homes commonly take extensions and driveways, and rendered houses often need re-rendering, roofline renewal and window replacement.
None of this holds for every street in Castlereagh, which is why we look at your actual house before pricing removing a wall rather than assuming from its age alone.

How does the job run?
We look at the job
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about removing a wall.
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.
Booking the work
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.
On site to finish
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.
What you can expect from us
Common questions
Which postcodes in Castlereagh do you cover?
We cover BT2, BT4, BT5 and BT6, along with the rest of County Down. 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.
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.
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.
Does the Party Wall Act apply to wall removal?
The Party Wall etc. Act 1996 applies in England and Wales only. Removing an internal wall usually does not involve it, but if the beam bears into a wall shared with a neighbour, as is common in terraced and semi-detached houses, you must serve notice first. Scotland and Northern Ireland have no equivalent Act. We tell you during the survey whether notices are needed.
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.
