Floor joist repairs in March

A sagging or springy floor in a March 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.

How do local ground conditions affect floor joist repairs in March?

With roughly 21,000 people, March spans postcode districts PE15 in Cambridgeshire. We also take enquiries from nearby Wisbech (8 miles), Ely (13 miles) and Peterborough (14 miles).

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. 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. 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.

Repair options we may recommend

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

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

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 March?

Guide prices for floor joist repairs in March 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 March?

We do. March and the surrounding area are covered, including nearby Wisbech and Ely. A free initial assessment from your photos is the first step.

Is the ground in Cambridgeshire prone to subsidence?

Gault Clay underlies much of the Cambridge area and Oxford Clay the west of the county around Peterborough and Huntingdon, while the northern fens are peat and silt that can shrink as they dry. Both clay and peat ground can move with the seasons. Only an investigation can say why a particular building has moved.

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.

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.
