Settlement Cracks in Your Walls? We'll Tell You If They Matter in Smethwick

Settlement cracks are the ordinary background noise of a house. Buildings flex with heat, cold and moisture; materials shrink as they dry; foundations adjust slightly to ground conditions. The result is the fine cracks that appear in plaster and render in the first years after building, and along old lines for as long as the house stands. Most are cosmetic. The value of a proper assessment is knowing that yours are — and catching the rare one that isn't. This page explains the difference and how we deal with each.

What normal settlement looks like

Typical settlement and shrinkage cracks are fine — usually under a couple of millimetres — run in random or vertical patterns, follow weak points in plaster or render, and stay stable over months and years. They often reappear in the same place each summer as the building dries, and close again in wetter weather. Common locations include above door and window openings, where lintels concentrate movement, along the joints between different materials, and in new extensions as they dry out for the first year or two.

These cracks are worth repairing for appearance and to keep water out of the wall, but they are not a structural concern. The repair is raking out, filling with a flexible or matched material, and finishing — and doing it properly so the crack doesn't simply reopen along the same line a season later.

The signs that mean more than settlement

Some cracks deserve more respect. Wider than a few millimetres, tapering from thick to thin, running diagonally from opening corners, stepping down through mortar joints in brickwork, visible on both the inside and outside faces at the same position, or growing noticeably between one look and the next — these patterns suggest movement rather than mere shrinkage. Cracks that appear suddenly, or after a dry spell, tree removal, or nearby excavation, also carry more weight. Doors and windows that begin to stick, floors that begin to slope, or cracks accompanied by bulging walls all change the picture.

Where we find any of those signs, we say so plainly and recommend a structural engineer's assessment rather than a cosmetic repair. We make the area safe, document what we find with photographs and dated measurements, and help you arrange the referral. We would rather tell you a crack needs an engineer than fill it and hope.

How we assess on the visit

We look at every crack in the affected area, recording width, length, pattern and material — plaster, render, mortar or brick. We compare inside and outside positions, check for the companion signs of movement, and consider the history: when the cracks appeared, whether they change with the seasons, and anything that has happened around the property. Where a crack's status is genuinely uncertain, a monitoring gauge across it gives an objective answer over the following months, and we will set that up and explain how to read it.

Repairing the cosmetic ones properly

For confirmed shrinkage and settlement cracks, the repair is done to last: cracks are raked out to a clean edge, filled with appropriate flexible or fine filler, taped and scrimmed where plaster has parted, and finished to match. Around openings, we check that movement joints or sealant beads are doing their job. Where a crack reopens seasonally, a flexible filler that tolerates movement beats a rigid repair that cracks again — and we will say which approach suits your wall.

Honest expectations and aftercare

We cannot guarantee that a settlement crack will never reappear — buildings keep moving, and render in particular reopens along old lines. What we can do is repair with materials that tolerate that movement and explain what to watch for. Keep gutters working, watch for any crack that widens or changes character, and have new cracks assessed rather than filled if they behave unusually.

Booking your assessment

Book through maintenance-men.com or by phone. 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. The full cost of the work is quoted and approved before we start, with parts and materials quoted separately. Tell us where the cracks are and how long you have noticed them, and send photographs if you can.
