Floor joist repairs in Brecon
If a plumber or electrician has recently had the boards up at your Brecon home, the joists they worked around are worth a look. Deep notches and holes in the wrong place weaken joists quickly, and sistering them is usually a short, tidy job.

Which repair method suits a home in Brecon?
Splicing ends and fitting hangers
Where only the end has rotted, it is cut back to sound timber and a new piece is fixed alongside, bearing on the wall or on a new joist hanger. Missing or under-nailed hangers elsewhere are replaced at the same time. The damp in the wall must be fixed too.
Best for: Rotten joist ends in damp solid walls
Sleeper walls and ventilation
Settled or damp sleeper walls are rebuilt on a sound base with a damp-proof course under new timber plates. Blocked air bricks are cleared, extra ones added where the void has dead spots, and soil or paving heaped against the outside wall is lowered.
Best for: Damp ground floor voids or joists on poor supports
What happens when we carry out floor joist repairs in Brecon?
Photos and a call
Send photos of the dip or soft area, the outside wall at ground level and any air bricks. A short call about when it started, and any recent plumbing or heating work, tells us whether the problem is local or widespread.
Lift boards and inspect
On site we lift a few boards where the floor is worst and check the joist ends, sleeper walls and void with a moisture meter. Outside, we look for high ground, blocked vents and leaks keeping the timber wet.
Relay and ventilate
Boards are relaid or replaced, skirting refitted and air bricks cleared or added outside. We point out anything that would let damp back in, such as soil heaped against the wall, so the repair lasts.
Signs you may need floor joist repairs

Rules for floor joist repairs in Wales

Floor joist repairs in Brecon: questions and answers
What is the price of floor joist repairs in Brecon?
Guide prices for floor joist repairs in Brecon start from about £230 per joist, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out floor joist repairs in Brecon?
Survey visits to Brecon are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Does the ground around Brecon cause cracking?
Powys is largely older hard rock and glacial deposits, with alluvium in the river valleys. Clay shrinkage is uncommon, but older stone buildings and rubble walls bring their own structural issues. Only an investigation can say why a particular building has moved.
What causes rot in floor joists?
Damp causes almost all joist rot. Joist ends in damp walls, voids with blocked air bricks, leaking pipes and high outside ground levels keep timber wet enough for fungi to grow. Replacing timber without fixing the damp usually means the rot returns.
Is a sagging floor dangerous?
A gentle, long-standing sag is usually not dangerous, and many older floors have moved slightly over a century. A sag that is getting worse, soft boards or a floor dropping near a wall needs checking soon, because rotten joist ends can lose their bearing.
