Sinking Shed Base? We'll Fix the Ground First So the Repair Actually Holds in West Bromwich

A sinking base is different from a merely uneven one: unevenness is a static problem, while sinking means the ground beneath is still giving way, and anything built on it will follow it down. That's why we treat sinking bases as a ground problem first and a shed problem second — because the order of operations decides whether the repair holds.

Why bases sink

The ground beneath gives way for a few recognisable reasons: soil that was never compacted before the base was laid, soft or made-up ground, soil washed out by water flowing beneath the base from a downpipe, leaking drain or a slope that feeds rainwater under one corner, and organic matter in the soil — old roots, buried vegetation — decomposing and leaving voids. Heavier loads make it worse: a shed that has grown from a store to a workshop loads the ground more than it was prepared for. Sinking often shows first at one corner, where a door starts to bind and a gap opens under the base edge, and it accelerates after wet winters.

What we assess

We measure where and how much the base has dropped, and look for signs it's still moving — fresh cracks, widening gaps, doors that have worsened over recent months. We investigate the ground: drainage around the shed, water sources, the base's construction and what lies beneath it where practical. We check what the sinking has done to the shed — racking, floor stress, wall gaps, door problems — because the shed's condition shapes what's worth doing. Before any digging or ground investigation, we locate underground services carefully and use detectors where appropriate; no scan guarantees what's below, so we'd ask you to check any utility plans you have. On older sheds we don't disturb any material that could contain asbestos and recommend testing instead.

Repair options — and the honest one

The durable answer starts with the ground: dealing with the water that's washing soil out, then stabilising and compacting the ground beneath the failed area. From there the base itself is corrected — re-supported on compacted material, extended onto sound ground, or rebuilt where the original was never adequate. Only then do the shed-side repairs make sense: re-levelling the floor, easing the frame back to square and sorting doors that have been fighting the movement. We'll say plainly if the situation calls for a different answer — a persistently wet or soft patch of garden where the shed stands may mean the honest recommendation is relocation to sound ground rather than an expensive battle with the site, and sometimes a badly distorted shed isn't worth re-founding. Every option is quoted with the full cost approved before work starts, and materials are quoted separately.

Weather, timing and limits

Groundwork needs dry conditions: wet soil gives false levels and compacts poorly, so we schedule around the forecast and tell you plainly if weather must delay the job. Sinking-base repairs are among the more involved shed jobs, and if the work needs more than a day it's staged, with each stage quoted and approved. We can't guarantee that ground won't move again — on difficult sites, drainage management is an ongoing matter — but a repair that treats the cause, not just the symptom, is the difference between fixing it once and fixing it every few years.

Booking your assessment

Call or book through the website and tell us the base type, how long the sinking has been developing, whether it's getting worse, what the ground and drainage are like around the shed and whether doors or walls have started misbehaving. You'll pay a booking fee when you book, labour is charged hourly at a rate that depends on how soon you need the visit, and the full cost is quoted and approved before work starts, with any parts quoted separately.
