Clay shrinkage is less of a concern in Ayrshire, so other causes such as drains, poor footings or older walls are checked first. Historic coal workings are recorded beneath parts of Ayrshire, and a coal mining search is worth checking where movement is unexplained. Across Ayrshire, most homes are sandstone villas and terraces in the coastal towns, miners' rows and post-war estates.

Methods for floor joist repairs

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

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.

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.

Frequently asked questions

How much should I budget for floor joist repairs in Kilwinning?

Guide prices for floor joist repairs in Kilwinning start from about £240 per joist, including VAT, on Scotland 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 Kilwinning?

Why do houses in Ayrshire crack?

Ayrshire has a large coalfield, especially in the east around Kilmarnock and Cumnock, with recorded workings, and raised-beach sands and gravels along the coast. Only an investigation can say why a particular building has moved.

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.
