Bowing wall repairs in Newport
A slight lean is common on houses of a certain age in Newport, and many have stood that way for generations. A growing bow, crushing bricks or a gap opening at the skirting is different, and is worth checking promptly.

What should you know about the ground under Newport?
Postcode districts NP10, NP19, NP20 cover Newport, a Gwent town of about 160,000 people. Nearby places we cover include Risca (5 miles), Cwmbran (5 miles) and Abercarn (7 miles).
Parts of Gwent have clay that can shrink near trees in dry spells. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Gwent: valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.
Repair options we may recommend
Restraint ties into the floor
Stainless restraint ties are drilled through the wall and fixed into the floor joists or into blocking between them. Where joists run parallel, noggins are fitted across several joists so the tie has something solid to hold. A neat plate or a buried fixing is left on the outside face.
Best for: Walls bowing at floor level where joists run alongside
Stitching a delaminating wall
Where the layers of a solid wall have separated, long stainless ties are drilled in from the face and bonded into the inner layer to bind the wall together again. This is often combined with restraint ties, so the wall is both reconnected through its thickness and tied back to the structure.
Best for: Solid walls where the outer layer has pulled away
What to expect when we carry out bowing wall repairs
Assess the bow
We look at where the wall bows, how far it is out of plumb and how the floors and roof meet it. Photographs from your phone held flat against the wall often show the shape clearly before anyone visits.
Decide restrain or rebuild
If the wall is badly out of plumb, has bricks crushing or follows removed internal walls, we recommend an engineer, and can arrange one. Their view sets whether restraint is enough or a section needs rebuilding.
Open up inside
Floorboards or a ceiling strip are lifted along the affected wall to expose the joists. We fit noggins where joists run alongside, and plan furniture moves with you, since this is the most disruptive part of the job.

Your bowing wall repairs questions
How much should I budget for bowing wall repairs in Newport?
Guide prices for bowing wall repairs in Newport start from about £920 per wall, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Newport?
Yes. We take enquiries from across Newport, including NP10, NP19, NP20, and from nearby places such as Risca and Cwmbran. Send photos for a free initial view and we will tell you what happens next.
Why do houses in Gwent crack?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
Can a bowing wall be pushed back straight?
Usually not. Masonry rarely returns to plumb without cracking, so the normal aim is to stop further movement and leave the wall where it is. If the bow is too great to accept, that section is rebuilt rather than forced back.
Do restraint ties show on the outside?
Some do and some do not. Certain ties leave a small round or square plate on the outside face, while others are fully recessed and pointed over. Straps fitted from inside leave no outside trace at all. We agree the finish with you before work starts.
