Which repair method suits a home in Market Harborough?
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
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

Floor joist repairs in Market Harborough: questions and answers
How much should I budget for floor joist repairs in Market Harborough?
Guide prices for floor joist repairs in Market Harborough start from about £245 per joist, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Leicestershire crack?
Leicestershire has Mercia Mudstone, Lias clay and glacial till across much of the county, with the Coalville and Swadlincote coalfield in the north-west. Clay soils near large trees can move with the seasons. 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.
Why is my floor bouncy?
A bouncy floor usually means the joists are deflecting too much, often because they span too far, have lost their strutting or have been weakened by notches. It rarely means imminent failure, but it is worth checking, especially if the bounce appeared after work in the room.
