Floor joist repairs in Shrewsbury
If a plumber or electrician has recently had the boards up at your Shrewsbury home, the joists they worked around are worth a look. Deep notches and holes in the wrong place weaken joists quickly, and sistering them is usually a short, tidy job.

Is Shropshire prone to ground movement?
With roughly 77,000 people, Shrewsbury spans postcode districts SY1, SY2, SY3 in Shropshire. Neighbouring towns we cover: Telford (13 miles) and Oswestry (16 miles).
Shropshire has a mix of ground, with clay in some places and firmer rock in others. Parts of Shropshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Shropshire, most homes are timber-framed and brick town houses, industrial terraces around Telford, and new-town estates.

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
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
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.
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 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.

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
What is the price of floor joist repairs in Shrewsbury?
Guide prices for floor joist repairs in Shrewsbury start from about £250 per joist, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out floor joist repairs in Shrewsbury?
Yes. We take enquiries from across Shrewsbury, including SY1, SY2, SY3, and from nearby places such as Telford and Oswestry. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Shrewsbury cause cracking?
Shropshire has very varied rock, from Mercia Mudstone on the north Shropshire plain to the Coalbrookdale coalfield under Telford, where historic shallow coal, clay and ironstone workings are widespread. 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.
What causes rot in floor joists?
Damp causes almost all joist rot. Joist ends in damp walls, voids with blocked air bricks, leaking pipes and high outside ground levels keep timber wet enough for fungi to grow. Replacing timber without fixing the damp usually means the rot returns.
