Methods for 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

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

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. 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.

Symptoms that point to floor joist repairs

  • A musty smell, or fungal strands showing between the boards
  • Ceiling cracks below that follow the line of the joists
  • 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 Mirfield?

Guide prices for floor joist repairs in Mirfield start from about £240 per joist, including VAT, on Yorkshire and the Humber 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 Mirfield?

We do. Mirfield and the surrounding area are covered, including nearby Dewsbury and Cleckheaton. A free initial assessment from your photos is the first step.

Why do houses in West Yorkshire crack?

West Yorkshire lies largely on the Coal Measures, with shallow historic workings around Leeds, Wakefield and Kirklees, and gritstone hills to the west. Steep sites mean retaining walls are common. Only an investigation can say why a particular building has moved.

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.

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.
