What is the ground like in North Yorkshire?
North Yorkshire ranges from limestone dales and moors to clays and glacial deposits in the Vale of York, with the Selby coalfield in the south and ironstone workings in Cleveland. Teesside has areas of soft and made ground.
Parts of North Yorkshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across North Yorkshire, most homes are stone cottages, Georgian and Victorian houses in York and Harrogate, and brick terraces on Teesside.
How we usually approach floor joist repairs
Sistering a joist
A new length of treated timber, the same depth as the original, is bolted or screwed alongside the damaged joist so the two share the load. It is the quickest fix for a notched, cracked or sagging joist that is otherwise sound, usually after lifting a few boards.
Best for: Cut, cracked or sagging joists with sound ends
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 during floor joist repairs, step by step?
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.
Written quote
You get a no-obligation written quote listing which joists are sistered, spliced or replaced and any sleeper wall or ventilation work. It becomes a fixed price in writing once the repair is specified.
Repair the structure
Boards are lifted and numbered if they are going back, and rotten timber is cut out. New treated timber is fixed and checked with a level before strutting, hangers and any restraint straps go in.
What to look for before calling about floor joist repairs

Questions about floor joist repairs in North Yorkshire
Is the ground in North Yorkshire prone to subsidence?
North Yorkshire ranges from limestone dales and moors to clays and glacial deposits in the Vale of York, with the Selby coalfield in the south and ironstone workings in Cleveland. Teesside has areas of soft and made ground. Parts of North Yorkshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will floor joist repairs cost in North Yorkshire?
On Yorkshire and the Humber rates, floor joist repairs starts from about £240 per joist, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
What is sistering a floor joist?
Sistering is fixing a new length of timber alongside an existing joist so the two share the load. It strengthens a notched, cracked or sagging joist without removing it, so it is quicker and less disruptive than replacement.
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.
Will my insurance pay for rotten floor joists?
Usually not, because rot, woodworm and gradual wear are standard exclusions. Damage from a sudden escape of water, or a floor that dropped through subsidence, may be treated differently. Check your policy, and tell your insurer before permanent repairs start if either applies.
