Why walls crack here

Why walls crack in Flintshire

Flintshire has several things that can contribute to masonry movement, depending on the building and its history. Parts of Deeside — Sealand, Queensferry, Shotton and the lower parts of Connah’s Quay — sit on low-lying ground reclaimed from the estuary, where softer ground and a higher water table may make settlement more likely in some properties. Parts of the county sit over former coal workings (around Buckley, Mold, Leeswood, Northop and Bagillt) or old lead mines (Halkyn Mountain and around Holywell), and old workings and made ground can, in some places, move. In the hill villages, clay and shale soils can shrink in a dry summer and swell in a wet winter.

Add an exposed climate off the Dee, a good deal of rendered post-war housing in which cracking may not show until it is established, and lintels and wall ties in some houses now fifty or sixty years old, and cracked walls are one of the more common calls we get. None of this tells you what is happening in your wall — location and property age are not a diagnosis. It does mean the cause is worth establishing before anything is filled or stitched, which is how we work.

FLINTSHIRE — INTERNAL MASONRY WALL

Recent wall crack repair project

A house in Flintshire where a crack in an internal masonry wall kept coming back through the plaster and decoration, however many times it was filled. The owner asked us to look at it rather than fill it again.

BEFORE

Recurring cracking through the plaster

The crack had been filled and decorated over more than once and had reopened each time — the sign of a wall that is moving, not of a bad filler. We inspected and advised that a structural engineer should establish the cause before any repair was done.

The customer instructed an engineer. The report attributed the cracking to thermal and seasonal movement in the wall and specified crack stitching as the repair.

DURING

Helical bars across the crack

With the plaster stripped back to the brickwork, we cut slots into the mortar joints across the line of the crack, cleaned them out and bedded stainless steel helical bars into them in resin, then repointed the slots. The bars tie the masonry on either side of the crack together so that the movement is carried along the wall rather than opening the crack.

The stitching was carried out to the engineer’s specification.

AFTER

Replastered and finished

The wall was replastered, new skirting fitted and the room decorated. Building Control inspected and signed the works off.

The repair is not visible once plastered.

This is what a straightforward crack stitching repair looks like when the cause has been established first: an engineer’s report, bars to the specification, and making good so nothing shows. We do not claim the wall will never move again — that is not what stitching does — but the repair was made for the cause that was found.

What crack stitching is

Crack stitching — how we repair cracks in walls and brickwork

Most of the cracked walls we stitch in Flintshire — rendered or bare, estate house or stone cottage — are repaired the same way once the cause is known. Slots are cut into the horizontal mortar joints at intervals across the crack, cleaned out, and stainless steel helical bars are bedded into them in resin. The bars tie the masonry on either side of the crack back together and spread the load along the wall, and the slots are repointed so the repair is largely invisible once finished. It is used on brick, block and stone walls, inside and out.

What it is not is a cure for whatever caused the crack. A wall that is still moving because a lintel has failed, because it is not tied to the floors, or because the ground beneath it is moving, will crack again — stitched or not. So we do not quote stitching until the likely cause is clear. Where the movement is significant or the cause is unclear, we say so and recommend a structural engineer, whose report we then work to. The main structural cracks page explains the causes and the repair options in full.

Wall crack and brick crack repair in Flintshire

Flintshire is where we are based, and it is where we see more cracked walls than anywhere else — our office in Ewloe puts most of the county within a short drive.

Whatever the house, the approach is the same: look at the crack properly, establish what is causing it, and only then repair it. Where the movement is significant or the cause is unclear we recommend a structural engineer and carry out the works to the report — the Flintshire job on this page ran that way.

What we find across the county

Flintshire property and masonry considerations

What comes up most often in Flintshire houses:

  • Render versus structure — On the rendered houses of Connah’s Quay, Shotton, Queensferry, Mancot, Hawarden, Ewloe and Buckley, the first question is whether the crack is in the render or in the wall behind it. Telling the two apart comes first. Good photographs — close up and of the whole wall — often show which it is; where they don’t, it takes a close look and a tap on site, not a guess.
  • Estate houses and their lintels and ties — On post-war Deeside houses, cracking above windows and doors is often a lintel that has corroded or was never adequate, and cracking where the front wall meets the floors can be a wall that is not tied back to the structure. Both are repairable once the cause is established.
  • Older stone and brick — In Mold, Northop, Sychdyn, Cilcain, Holywell, Caerwys and the villages around them, older houses often have lime mortar, timber lintels and past alterations. A crack can be old and stable, or the result of a chimney breast removed or an opening enlarged years ago. We repair these walls in materials that suit them — lime, matched stone or brick — not hard cement.
  • The estuary and the weather — In Flint, Bagillt, Oakenholt, Greenfield and Mostyn, driving rain off the estuary finds every failed joint. Where water has played a part, the pointing or the drainage needs putting right as well as the crack, and any damp it has caused can be treated through our Flintshire damp proofing service.
  • Wales, and Building Control — Flintshire is in Wales, so where Building Control involvement is required the Building Regulations as they apply in Wales are the ones that count.

When to ask us to look

Cracks in walls worth sending us photos of

Most cracks in a house are cosmetic — hairline lines in plaster or render that come from drying out and normal seasonal movement. Some are not, and a description alone will not tell us which yours is. These are the cracks worth photographing and sending to us:

Cracks in the brickwork just above the soldier course over a window

Cracking in the brickwork just above a window head.

New, widening or recurring

A crack that has appeared recently, is getting wider, or comes back after it has been filled and decorated.

Stepped through the brickwork

A diagonal crack that follows the mortar joints in a staircase pattern — or, on a rendered Deeside house, a longer clean diagonal line showing through the render rather than a fine random one.

At the corners of openings

Cracks running from the top corners of windows and doors, or brickwork dropping above an opening.

On both faces of a wall

A crack you can see inside and outside at the same point.

With other symptoms

Doors and windows that have started to stick, gaps opening at skirtings or ceilings, sloping floors.

After a change nearby

Cracking that followed a drainage problem, a leak, tree work, an extension or excavation next door, an alteration inside the house — or, in the old mining villages, nothing obvious at all.

Damp, salts or spalled bricks around it

Damp patches, white salt deposits or bricks blowing or flaking near the crack — signs that water has been getting in for a while.

Bulging or leaning

A wall that is no longer flat or plumb, a gable that has moved, or gaps opening between sections of wall.

None of these is a diagnosis. They are reasons to have the wall looked at properly, so that whatever is done next is the right thing.

What drives the price

What wall crack and brick crack repair costs

We do not publish prices for crack repair, because the same-looking crack can be a half-day of stitching or a lintel replacement with scaffold. What decides the figure:

  • Number and length of the cracks
  • Wall type — brick, block, stone, rendered
  • Access — ground level, ladder or scaffold
  • Whether the cause needs its own work: lintels, restraint ties, drainage
  • The extent of making good: pointing, render, plaster, decoration
  • A structural engineer’s report, where one is needed, is instructed by you and priced separately

Every quotation sets out the scope of work in writing — the stitching, any other structural work and the making good — with one total price for the job.

    What else the repair may need

    Related work that can come with a crack repair

    Crack stitching is often part of the answer rather than the whole of it. Depending on what is causing the crack — and, where one is needed, what the engineer’s report finds — the repair may also involve:

    Lintel repair or replacement

    A failed or corroded lintel over a window or door is one of the most common causes of cracking above openings. The masonry is propped, the lintel replaced, the brickwork rebuilt and then stitched — lintel repair and replacement in Flintshire.

    Brick crack repair and replacement

    Cracked, spalled or frost-damaged bricks are cut out and replaced with matching units before the wall is stitched — brick repair in Flintshire.

    Repointing

    Failed or hard cement pointing lets water in and stops the wall moving as it should; repointing in the right mortar is often done alongside the stitching — repointing in Flintshire.

    Lateral restraint

    Where a wall is not adequately tied to the floors or roof, restraint ties or straps are installed to the engineer’s design as well as stitching the crack.

    Damp and water management

    Where water ingress or a drainage fault has contributed to the deterioration, the source is dealt with so the repair lasts — damp proofing in Flintshire.

    Structural alterations

    Where a previous alteration left the structure under-supported, the support is put right first — structural alterations in Flintshire.

    Wall ties

    On cavity walls, horizontal cracking along the bed joints can point to corroded ties. Where that is the finding, we replace the failed ties alongside the stitching.

    Internal cracks

    Cracks in internal walls are dealt with the same way. Cosmetic ones are filled, bonded and redecorated; structural ones are stitched, then replastered and finished so nothing shows.

    Where a repair involves replacement lintels, new supports or other work that may be notifiable, our Building Regulations guidance explains the overview.

    The questions we’re asked most

    Frequently asked questions

    My house is rendered — how do I know whether the crack is in the render or the wall?
    You often cannot from the surface, which is why we look properly rather than guess. Render cracks tend to be finer, more random and confined to the render; a crack in the masonry behind shows through as a longer, cleaner line — often diagonal or stepped — that comes back after patching. We check the line of the crack, whether it goes through at openings and corners and whether it shows inside as well — photographs of all three help — and, where needed, expose a small area of render on site to see the wall. On Deeside’s rendered estates this is the most common question we are asked.
    Do Welsh Building Regulations apply to a crack repair in Flintshire?
    Where they apply, yes — Flintshire is in Wales, so the Building Regulations as they apply in Wales are the ones that count. Whether Building Regulations or Building Control involvement is required depends on the scope of work. We will explain the position for your proposed repair and, where agreed, coordinate the process with the relevant parties. Repairs involving replacement lintels, new supports or restraint ties are more likely to need it than stitching on its own; the Flintshire job on this page involved Building Control and was signed off.
    My engineer has specified crack stitching — can you carry it out to their report?
    Yes, and it is how we prefer to work. Send us the report; we quote for the works as specified — stitching, and any lintel, restraint or masonry work the engineer has called for — carry them out to the specification, photograph each stage, and, where agreed, coordinate any Building Control involvement the scope requires. If anything in the report needs clarifying we go back to the engineer, not around them.
    How quickly can you look at a crack in Deeside, Mold or Buckley?
    Our office is in Ewloe, so most of Flintshire is a short drive. Send photographs on WhatsApp or by email: where they show enough, we price from them; where they don’t, we book a visit at a time that suits you.
    Can you tell from photographs whether my crack is serious?
    Often they tell us a good deal. A few photographs show us where the crack is, roughly how wide it is, what kind of wall it is in and what is around it — send the crack close up with something for scale, the whole wall, and the openings and ground nearby. If they show enough, we can quote in writing from them. If they don’t, or the movement looks significant, we’ll say so — and arrange a visit or recommend a structural engineer.
    How much does crack stitching cost?
    It depends on the number and length of the cracks, the wall type, access, whether the cause needs its own repair — a lintel, restraint ties, drainage — and how much making good is involved. A short run of stitching at ground level is a modest job; a lintel replacement with scaffold and re-rendering is not. We do not publish prices, but every quotation sets out the scope of work in writing, so you can see exactly what is included. Most jobs we can price from photographs — send yours on WhatsApp or by email and we’ll come back with a written quotation.
    Do you repair cracks in brickwork as well as in render and plaster?
    Yes — most of what we do is brick crack repair. A crack in render or plaster is often only in the finish and is filled once the cause is ruled out; a crack in the brickwork itself is repaired by crack stitching across the mortar joints, with any cracked or spalled bricks cut out and replaced and the joints repointed to match. Block and stone walls are repaired the same way. What we do not do is stitch a wall that is still moving — the cause comes first.
