External mastic in Redbridge
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have brick movement joints where the sealant has split and panel joints letting water in, we can put it right, on brickwork movement joints, copings & trims and render & cladding joints alike.
Somewhere as small as Redbridge, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In a small place like Redbridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Common questions in Redbridge
I let a flat near Redbridge station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Redbridge within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
What does external mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we can’t put right
We will not take on work that won’t last, so these are the limits:
- Failed render or damaged cladding panels
- Cracked brickwork or render that needs a builder or plasterer
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Copings & trims
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
What we are called out for in Redbridge
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
For landlords with property near Redbridge station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before you book anyone
- What the cure time is
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- Is VAT in the price?
The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Redbridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

What external mastic looks like in Redbridge
Redbridge is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Southampton Tudor House and Garden (about 3.3 miles south-east) nearby, there’s older building stock in the area around Redbridge as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Redbridge Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Homes close to All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Redbridge is about 1 mile east of Totton, in Southampton. Jobs in Redbridge get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 40 towns and villages across Southampton.
