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.
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.

How we usually approach 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

Questions about floor joist repairs in Newmarket

How much will floor joist repairs cost in Newmarket?

Guide prices for floor joist repairs in Newmarket start from about £260 per joist, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Newmarket?

Yes, Newmarket is covered, along with postcode districts CB8. We also cover nearby Haverhill and Ely.

Is the ground in Suffolk prone to subsidence?

Much of Suffolk is chalky boulder clay, with London Clay around Ipswich and Felixstowe and sandier ground in the Breckland and on the coast. The clay areas are prone to seasonal shrinkage near trees. 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.
