Repointing is raking out old, crumbling mortar from between bricks and replacing it with fresh mortar, sealing the joints against rain and protecting the wall; brickwork repairs replace spalled or cracked bricks and rebuild damaged sections.
If you live in Isleworth and are weighing up brickwork and repointing, the starting point is a visit to measure up and talk through what you want, which costs nothing. We cover homes across TW1, TW3, TW4 and TW5, and a typical project of this kind in London lands somewhere in the £3,200–£7,800 bracket, including VAT. The exact figure depends on size, access and the finish you choose.

What are homes like around Isleworth?
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
Knowing the typical building types in London helps, but a survey of your own home in Isleworth is what decides the right approach to brickwork and repointing.
Do you need permission in Isleworth?
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Isleworth comes under England, covered below, and we raise any questions with the council before your quote is finalised.
Repointing and repairing brickwork with matching materials is maintenance, so it does not need planning permission in England. On a listed building, work that affects its character, including a change of mortar or brick, may need listed building consent.
Building Regulations do not normally apply to repointing or brick repairs, but rebuilding a wall, chimney or structural section can need building control involvement.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
A visit to your home
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for brickwork and repointing, and photograph or measure anything the quote needs to reflect.
Your fixed price
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Booking the work
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
What you can expect from us
Common questions
What causes bricks to crumble?
Bricks usually crumble, or spall, when water gets into them and turns to ice, pushing the face off. This is often caused by hard cement mortar or impermeable paint trapping moisture in soft bricks, or by leaking gutters soaking the wall. Damaged bricks can be cut out and replaced with matching ones, or turned round if the back face is sound. We fix the cause at the same time.
Which postcodes in Isleworth do you cover?
We cover TW1, TW3, TW4 and TW5, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Can you match the colour of my existing mortar?
Matching mortar colour is done by choosing the right sand and, where needed, adding pigment or using a coloured lime. We make test panels and let them dry, because mortar looks darker when wet. The joint style, such as flush, bucket handle or weatherstruck, also affects the look. An exact match is not always possible on old walls, but a careful match blends in well.
Do you cover Hounslow, Heston and Richmond?
Yes. As well as Isleworth, we cover Hounslow, Heston and Richmond and the rest of London. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
How much does repointing a house cost?
Repointing a typical 3-bed semi costs £3,200–£7,800, including scaffolding. As a guide, allow roughly £25–£55 per square metre of wall plus fixed costs for access and set-up. Chimney stacks, lime mortar and brick replacement add cost, while repointing a single elevation costs less. We confirm a fixed price after inspecting your walls.
