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

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

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.
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.
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.

What to look for before calling about floor joist repairs

Floor bouncing, or ornaments rattling, when someone walks across
A musty smell, or fungal strands showing between the boards
Floor dipping towards an outside wall or in the middle of the room

Questions about floor joist repairs in Brentwood

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

Guide prices for floor joist repairs in Brentwood 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.

Why do houses in Essex crack?

London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. Only an investigation can say why a particular building has moved.

Is a sagging floor dangerous?

A gentle, long-standing sag is usually not dangerous, and many older floors have moved slightly over a century. A sag that is getting worse, soft boards or a floor dropping near a wall needs checking soon, because rotten joist ends can lose their bearing.

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.
