Cracked Walls Repaired — With a Proper Check Before We Fill Anything in Shirley

A crack is the wall's way of saying something, and the message ranges from "nothing to worry about" to "get this looked at". New plaster shrinks and cracks hairlines around doors and window reveals. Buildings settle and move with the seasons. But cracks can also announce structural movement, failed lintels, or damp forcing its way through — and filling one of those over is the worst possible response, because it hides the evidence while the cause carries on.

Telling cosmetic cracks from concerning ones

Cosmetic cracks tend to be hairline to a couple of millimetres wide, run in the plaster rather than through the structure, sit at known weak points — board joints, around lintels, corners of door and window openings — and stay stable over months. Concerning cracks look different: they are wider and growing, run diagonally or step across brick or block courses, appear the same inside and out, pair with doors and windows that start sticking, or come with damp staining. A crack that reopens after being filled is also telling you something.

Our assessment comes before any filler

We look at the crack's width, direction and pattern, check whether it runs through the plaster only or through the structure, examine the surrounding wall for damp or bulging, and ask what has changed recently — new windows, removed walls, a nearby tree, plumbing works. If the crack looks cosmetic, we proceed. If it looks like movement, we stop and recommend a structural engineer or building surveyor before any repair is attempted. If it comes with water ingress, a damp specialist is the right call. And if the wall carries older textured coatings we suspect could contain asbestos, we will not disturb them — that needs a licensed contractor.

How cosmetic cracks are repaired

A hairline shrinkage crack is opened up slightly — raked out along its length — so filler has something to key into, brushed clean, then filled with a suitable filler; flexible filler where the joint may move slightly, rigid where it will not. Cracks along plasterboard joints are re-taped and filled, which is more durable than filling bare. Wider cosmetic cracks may need mesh or tape embedded in the fill to spread the stress. Everything is dried properly, sanded flush, and cleared of dust.

One honest caveat: even a well-repaired cosmetic crack can reappear if the wall continues to move seasonally, which is why flexible filler and modest expectations matter at known movement points.

What the visit covers

The estimate is for assessing and repairing the cosmetic cracks you describe. If assessment shows the cracks need a specialist first, we tell you — and the right response is a survey, not a repair. Decoration is not automatically included: a repaired crack needs priming and repaint to blend, usually across the whole wall, and that is separate work we can quote if wanted.

Aftercare

Keep an eye on repaired cracks through the seasons. If one reopens, widens, or spreads, photograph it with something beside it for scale and get it reassessed — that history is valuable to any surveyor later.

Booking

Same-day visits may be available for straightforward cosmetic repairs. Book at maintenance-men.com: you pay a booking fee on booking, the hourly labour rate depends on how soon you need the visit, and the full cost is quoted and approved before work starts. Repair materials, where needed beyond standard filler, are identified and quoted separately.

Photographing a crack when you first notice it, with a coin or ruler beside it for scale, is genuinely useful. If it changes over the following weeks, those dated photos give any later surveyor a clear record of whether the crack is stable or progressing — and that is exactly the question a specialist needs answered.
