From first photo to finished repair

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.

Methods for floor joist repairs

Replacing joists and boards

When rot or woodworm runs through most of a floor, it is usually cheaper to replace the joists, strutting and boards together. Where joists run parallel to an outside wall, restraint straps tie the new floor back to it so the wall keeps its lateral support.

Best for: Widespread rot, or a whole floor that has dropped

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

Rules for floor joist repairs in England

Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.

Frequently asked questions

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

Guide prices for floor joist repairs in Hexham start from about £230 per joist, including VAT, on North East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Yes, Hexham is covered, along with postcode districts NE46. We also cover nearby Consett and Blaydon-on-Tyne.

Why do houses in Northumberland crack?

South-east Northumberland around Blyth, Ashington and Cramlington lies on the Northumberland coalfield, worked extensively in the past, under a cover of glacial clay. The north and west are hard rock and moorland. Only an investigation can say why a particular building has moved.

Can floor joists be repaired without taking up the whole floor?

Yes, in most cases only the boards over the affected joists need lifting, and three or four boards are often enough to sister a joist or splice a rotten end. Widespread rot is the exception, because the whole floor must come up to remove the decay.

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.
