External mastic in Burcot, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with movement joints filled with mortar instead of sealant and plants rooting in failed movement joints, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Burcot is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How the job changes by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Concrete & block
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Façade panels
Why it’s worth doing now in Burcot
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Burcot, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Outside joints around Burcot
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Clifton Hampden Manor (about 1.2 miles west) are a reminder that the area around Burcot 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.
If you look after a building such as Abbey Woods Academy, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Saint Mary and Saint Berin include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Culham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Burcot: your questions answered
I let a flat near Culham station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Burcot?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
