Why does the ground in Hampshire matter for floor joist repairs?

Postcode districts PO14, PO15, PO16 cover Fareham, a Hampshire town of about 42,000 people. Neighbouring towns we cover: Portsmouth (5 miles), Hedge End (7 miles) and Waterlooville (7 miles).

Shrinkable clay is widespread in Hampshire. Ground movement here is more often linked to soils, drains and trees than to mining. Across Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

Methods for floor joist repairs

Sistering a joist

A new length of treated timber, the same depth as the original, is bolted or screwed alongside the damaged joist so the two share the load. It is the quickest fix for a notched, cracked or sagging joist that is otherwise sound, usually after lifting a few boards.

Best for: Cut, cracked or sagging joists with sound ends

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

From first photo to finished repair

  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. 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.

  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.

Symptoms that point to floor joist repairs

  • A gap opening up between the skirting board and the floor
  • A musty smell, or fungal strands showing between the boards
  • Floor dipping towards an outside wall or in the middle of the room

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 Fareham?

Guide prices for floor joist repairs in Fareham 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.

Can you survey a property in Fareham?

Yes. We take enquiries from across Fareham, including PO14, PO15, PO16, and from nearby places such as Portsmouth and Hedge End. Send photos for a free initial view and we will tell you what happens next.

Why do houses in Hampshire crack?

Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal 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.

Why is my floor bouncy?

A bouncy floor usually means the joists are deflecting too much, often because they span too far, have lost their strutting or have been weakened by notches. It rarely means imminent failure, but it is worth checking, especially if the bounce appeared after work in the room.
