Why walls crack here

Why walls crack in Chester

In Chester the cause of a crack is often the building rather than the ground — though that cannot be assumed without looking. The city stands on sandstone beside the Dee, and in many older houses the cause turns out to be a failed lintel, a spread brick arch, a chimney breast taken out without adequate support, or a solid wall that has been taking in water through hard cement pointing for years. Many of the Victorian and Edwardian houses of Hoole, Handbridge, Boughton and Newton were built on shallow footings with timber lintels, and a century of alterations may have left some of them carrying load in ways the builder never intended.

Large trees in the older suburbs — Curzon Park, Hoole, Queens Park — can draw moisture from the ground in a dry summer, and old clay drains that have cracked can put water back in the wrong place. On the post-war estates the picture may be different: cavity walls whose ties can be corroding, and steel lintels that may have rusted. Different causes, different repairs — and the age of the house will not tell you which. That is why the cause comes first.

CHESTER — RENDERED SEMI-DETACHED HOUSE

Recent brick crack repair project

A rendered semi-detached house in Chester with cracking across the elevations and, inside, through the stairwell. We inspected and advised a structural engineer; the engineer’s report identified failed lintels over the openings as the cause.

BEFORE

Cracking across the elevations and through the stairwell

Cracks ran across the external elevations and showed internally through the stairwell — the pattern of masonry above openings that has lost its support. The engineer’s report confirmed failed lintels.

The repair was specified as replacement lintels, rebuilding of the affected brickwork, crack stitching and restraint straps.

DURING

Propping, new lintels and rebuilt brickwork

The masonry above each opening was propped and needled, the defective sections cut out, and new steel lintels installed to the engineer’s specification with a cavity tray over each. The brickwork was rebuilt and toothed into the existing wall.

The cracked masonry was then stitched with stainless steel helical bars, and restraint straps were fixed across the ceiling joists and tied into the wall.

New galvanised steel lintel installed over an opening with a damp-proof cavity tray laid over it, supported on temporary props — The new galvanised steel lintel in place, still carrying temporary support. The cavity tray has been temporarily folded back for photographic purposes to clearly show the lintel installation.

AFTER

Structural repairs complete

With the lintels replaced, the brickwork rebuilt, the cracks stitched and the restraint straps in, the structural repairs were complete and Building Control signed them off.

Quirks carried out the structural repairs only — a general builder then took the property on for the refurbishment. The photograph shows the rebuilt brickwork over the opening with the temporary propping removed, which is where Quirks’ scope ended.

Rebuilt brickwork over the opening after galvanised steel lintel installation, Chester — The opening with the new lintel in, the brickwork rebuilt and toothed in, and the temporary propping removed.

This job shows why the cause has to be found first: stitching the cracks without replacing the lintels would have closed them for a season. Our scope on this project was the structural repair — propping, lintels, rebuilding, stitching and restraint — and the case study claims nothing beyond it.

What crack stitching is

Crack stitching — how we repair cracks in walls and brickwork

On Chester’s older brick, crack stitching has one great advantage: it sits inside the mortar joints, so a period wall keeps its face. 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 a polymer grout. 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 Chester

Chester’s housing is older than most of the region’s, and cracked walls here are as likely to be a Victorian lintel or a long-ago alteration as anything happening in the ground. The terraces and villas of Hoole, Handbridge, Boughton, Newton and the Garden Quarter are solid-wall brick, built with timber lintels or brick arches over the openings, lime mortar that has often been repointed in cement since, and a hundred years of chimney breasts removed and openings widened. The 1960s–80s estates of Upton, Blacon, Lache, Vicars Cross and Great Boughton are cavity-wall, with their own pattern: horizontal cracking where wall ties have corroded, and cracks above openings where a steel lintel has rusted.

Parts of the city and some of its older suburbs sit in conservation areas, which does not change whether a crack can be repaired but may change how: matched bricks, lime pointing, render made good to match. We establish the cause first, recommend a structural engineer where the movement is significant or the cause unclear, and carry out the works to the report — as on the Chester job on this page. The main structural cracks page covers the causes and the repair options in full.

What we find in and around the city

Chester property and masonry considerations

Chester’s cracks tend to fall into one of these.

Lintels over Victorian and Edwardian openings — The terraces of Hoole, Handbridge, Boughton and Newton were built with timber lintels behind a brick arch or soldier course. A century on, the timber has often rotted or the arch has spread, and the brickwork above the window drops — cracking from the top corners of the opening and sometimes showing inside through the reveals or, as on the Chester job on this page, through the stairwell. The repair is propping, a new steel lintel with a cavity tray, rebuilt brickwork and stitching — see lintel repair and replacement in Chester.
Alterations and chimney breasts — Many Chester houses have had a chimney breast removed or an opening knocked through in the last fifty years, not always with adequate support left behind. Cracking at first-floor level above a removed breast, or above a widened opening, is usually the structure telling you it is carrying load it was not designed for. Putting the support right comes before stitching — see structural alterations in Chester.
Cavity walls and wall ties — Upton, Blacon, Lache, Vicars Cross, Great Boughton and Huntington have 1960s–80s cavity-wall houses. Horizontal cracking along the bed joints at regular courses, sometimes with the outer leaf bowing, often points to corroded wall ties, though the ties have to be checked to confirm it. Where that is the finding, we replace the failed ties alongside the stitching rather than stitching alone.
Conservation areas and matching — Chester city centre and a number of its older suburbs are conservation areas, and much of the housing is worth matching properly whether or not it is. We replace bricks with matched units, repoint in lime where the wall is lime, and make render good to the existing finish — see repointing in Chester. The stitching itself is invisible once repointed; the rest of the repair should be too.
Water and old walls — Solid walls with failed pointing or a long-standing leak take water into the fabric, and saturated brick and mortar deteriorate and move. Where water has played a part we put the source right as part of the repair and treat any damp it has caused — see damp proofing in Chester.

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:

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, rather than a straight line through render or plaster.

At the corners of openings

Cracks running from the top corners of windows and doors, or brickwork dropping above an opening — common above the sash windows of Hoole and Handbridge terraces.

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, or a first-floor floor that has dropped above a removed chimney breast.

After a change nearby

Cracking that followed a drainage problem, a leak, tree work, an extension or excavation next door, or an alteration inside the house.

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.

Stepped cracking through brickwork — the cause is assessed before the repair is priced.

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 Chester.

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 Chester.

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 Chester.

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 Chester.

Structural alterations

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

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.

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. 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

There is a crack above the window on my Victorian terrace — is it the lintel?

Often, on a house of that age, but not always. Cracking from the top corners of an opening, with the brickwork above dropped or the arch spread, points to a lintel that has rotted or failed; the same pattern can also come from movement elsewhere. Photographs of the whole elevation — the lintel, the arch and the openings above and below — often show which it is; if they don’t, we will come and look. Where the lintel has failed, the repair is propping, a new steel lintel, rebuilt brickwork and stitching — the Chester job on this page is exactly that.

We are in a conservation area — will the repair show?

It should not. Crack stitching sits in the mortar joints and is repointed over; on facing brick it is very hard to find afterwards. Where bricks have to be replaced we match them as closely as the wall allows, and we repoint in lime where the wall is lime rather than in cement. On older brickwork a perfect match is not always possible and we tell you that beforehand. Conservation-area status affects external appearance rather than the repair itself, and a like-for-like repair rarely raises a planning question — where it might, we say so.

My 1970s house has a long horizontal crack along the brickwork — what is that?

Horizontal cracking along the bed joints at regular courses on a cavity-wall house often points to corroded wall ties, and it comes up on Chester’s 1960s–80s estates. It needs looking at rather than filling: the ties are checked and, where they have failed, we replace them alongside stitching the cracks. We cannot confirm it from a description or a photograph — the ties have to be checked — but it is the first thing we would look for.

My surveyor has flagged cracking on a house I am buying — can you help?

Yes. Send us the surveyor’s report and photographs of the cracking they have noted, and we will tell you whether it looks cosmetic or worth further investigation — and, where it is the latter, whether a structural engineer’s opinion is needed before you exchange. If a repair is needed we quote for it so you know the cost before you commit. See our pre-purchase repair quotation service for how that works.

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.
