Floor joist repairs in Burgess Hill

A sagging or springy floor in a Burgess Hill home usually has a simple explanation once a few boards are lifted. Rotten joist ends, careless notching and blocked air bricks account for most dipping floors in older houses, and each one has a clear, well-understood repair.

West Sussex is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Across West Sussex, most homes are Wealden cottages, 1930s semis and bungalows on the coast, and new-town estates in Crawley.

Repair options we may recommend

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

What to expect when we carry out floor joist repairs

  1. 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.

  2. 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.

  3. 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.

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.

Your floor joist repairs questions

How much will floor joist repairs cost in Burgess Hill?

Guide prices for floor joist repairs in Burgess Hill start from about £280 per joist, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you cover Burgess Hill?

Yes, Burgess Hill is covered, along with postcode districts RH15. We also cover nearby Haywards Heath and Lewes.

Is the ground in West Sussex prone to subsidence?

North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.

Will my insurance pay for rotten floor joists?

Usually not, because rot, woodworm and gradual wear are standard exclusions. Damage from a sudden escape of water, or a floor that dropped through subsidence, may be treated differently. Check your policy, and tell your insurer before permanent repairs start if either applies.

Do I need building control for floor joist repairs?

Usually not for like-for-like repairs to a few joists, but replacing a whole floor structure can be building work. In Scotland that generally needs a building warrant, and in Northern Ireland council building control applies. We deal with building control where the work needs it.
