External mastic in Brockbridge, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. If you’re dealing with failed seals between different materials and weeds or debris growing in open joints, we can help, on brickwork movement joints, render & cladding joints and joints between brick and frames alike.
Around Brockbridge, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Looking after it afterwards
After the cure time, these simple habits help:
- Walk round the building once a year and look at the joints
- Don’t let climbing plants root in the sealant
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Once a joint cannot move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. In a small place like Brockbridge, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Advice
Why act early in Brockbridge
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Brockbridge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Brockbridge buildings and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Meonstoke Church of England Infant School, larger buildings have long runs of movement joint that eventually need resealing.

Quotes for external mastic in Brockbridge
The price is agreed before any work begins. It takes into account:
- How much there is to do
- Whether the work is at height
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Where the property is
- If someone has resealed it before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Copings & trims
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
Common problems we fix in Brockbridge
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Most people get in touch when they notice one of these:
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
In the older streets around Church of St Mary and All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Common questions in Brockbridge
Do you cover Brockbridge for external mastic?
Yes. Our work covers London and the South East, and Brockbridge is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Is there a guarantee on external mastic in Brockbridge?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Should I point up the gap in my brickwork?
No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
