External & façade joints in Langley, Slough
Our applicators work in Langley on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep water from gutters off the wall
- Have failed joints looked at early
- Keep high-pressure jets off the joints
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
External mastic for homes and businesses in Langley
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We are often asked to deal with plants rooting in failed movement joints and failed seals between different materials, on copings & trims, render & cladding joints and façade panels.
Houses in smaller places like Langley can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Langley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Why book with us
- Experience in homes, commercial sites and hotels

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Walls and rooflines in Langley
Historic houses like Windsor Castle (about 2.7 miles south-west) are a reminder that the area around Langley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Mary the Virgin Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as The Langley Academy Primary, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Langley station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Questions from Langley
Do you cover smaller places like Langley?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Langley station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. For a job in Langley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Move anything stored near the joints
- Mention any parking rules near the property
- Mention any tricky access
