About our external mastic in Mimbridge
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have cracked joints where brick meets render or frames and damp patches traced to an open external joint, we can put it right.
Somewhere as small as Mimbridge, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, it’s backed by our 12-month guarantee.

The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Mimbridge, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Advice
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Brickwork movement joints
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Façade panels
- Concrete & block
What we’re called out for in Mimbridge
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
It’s worth asking for a quote if you see:
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
If you live in an older home near Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check the sealant is paintable before painting near it
- Fix overflowing gutters above sealed joints
- Do not let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
FAQs for Mimbridge
I let a flat near Woking station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Mimbridge?
Yes, Mimbridge is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Mimbridge buildings and the weather
Historic houses like Botleys Mansion (about 3.1 miles north-east) are a reminder that the area around Mimbridge has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Woking station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Woking High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
