Subsidence Cracks in Your Walls? Safety First, Then Proper Answers in Edgbaston

Subsidence means the ground beneath part of your home is moving — shrinking, washing away, or compressing — so the building above settles unevenly and cracks appear. It is serious, but it is also diagnosable, monitorable and in many cases resolvable, and the first step is always proper assessment rather than repair. This page explains what subsidence looks like, what we do when we attend, and how the process should run to protect your home and your insurance position.

What subsidence damage looks like

The classic signs are cracks that are wider than a few millimetres, taper — thick at one end, thin at the other — run diagonally, and appear both inside and outside at the same position. Doors and windows begin to stick as frames distort. Floors may slope. Cracks tend to grow over time rather than staying stable. Patterns around the base of the building, or spreading from the corners of openings, carry particular weight.

The causes behind it are varied: clay soils that shrink in dry summers and swell in wet winters — a known issue across parts of the West Midlands — trees and large shrubs drawing moisture from the ground, leaking drains softening the soil, old mine workings and made ground, and broken drainage washing support away. Each cause points to a different remedy, which is why diagnosis matters more than anything.

Not every big-looking crack is subsidence

It is worth saying plainly: many frightening-looking cracks are thermal movement or settlement — the building adjusting as materials age — and they are stable, harmless and cheap to deal with. New build homes crack as they dry. Old walls crack along old lines each summer. The difference between harmless movement and subsidence is pattern, progression and evidence, and that difference is established by assessment and monitoring, not by guesswork in either direction.

What we do on the visit

First, safety: we check whether any masonry is loose or at risk, and secure or carefully remove anything hazardous so the area is not a danger to you. We then record what we find — crack positions, widths, lengths, patterns, and matching signs inside the property — with photographs and dated measurements. That baseline matters: engineers and insurers work from progression over time.

We also look for the causes we can identify: drain runs and their condition, trees and their distance from the building, ground levels, drainage and guttering. Then we give you our honest view and the recommendation a crack of this pattern deserves — a structural engineer's report, often alongside monitoring over several months. We help you arrange that and hand over our notes and photographs. We do not carry out underpinning or other structural remedies ourselves; the engineering decision must come first, and we will say so plainly.

Between the visit and the report

Monitor the cracks with dated marks or gauges, and note any change. Keep water away from the building's base: fix leaking drains and gutters promptly, and don't add or remove large trees without advice. Don't fill or repair the cracks yet — the evidence is valuable. If cracks widen rapidly, walls bulge, or doors jam shut, escalate promptly.

After the engineer's report

The engineer specifies what is needed — which may be as simple as removing a cause, or as involved as underpinning. Once the structural work is settled, we can quote for the parts we do: drainage repairs, making good, repointing, brickwork replacement and redecoration-ready finishes. The sequence — engineer, then repair — protects you from paying for cosmetic work that the structural remedy would undo.

Costs and booking

You pay a booking fee when you book, and labour is charged hourly at a rate that depends on how soon you need the visit. Any work we do is fully quoted and approved before it starts, with parts and materials quoted separately. The engineer's report is a separate professional engagement, and we will explain how our work fits around it. Book via maintenance-men.com or by phone, and tell us where the cracks are, how wide, and whether they have changed since you noticed them.
