How we handle external mastic in Surrex
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you have plants rooting in failed movement joints and gaps where render, brick and frames meet, we can help, on render & cladding joints, copings & trims and joints between brick and frames alike.
Somewhere as small as Surrex, 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.
All of our work is guaranteed for twelve months.

Your questions about external mastic in Surrex
Will you come out to Surrex?
Yes, Surrex is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Kelvedon station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
How often do external joints need resealing?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The amount of work
- The type of sealant required
- Working hours on commercial sites
- Whether there’s mould to deal with
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
Asking for a quote
Before you ask for a quote, have a think about:
- Where the property is
- Pictures of the joints, sent by email
- The type of property
- How we’d reach the joints
If you are in Surrex and need external mastic, ring 0345 464 0079 or email us. Tell us what the problem is and where, and we’ll agree the price before any work begins.
Why act early in Surrex
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Surrex, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask before painting over external sealant
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Avoid pressure-washing directly into sealant joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Failed render or damaged cladding panels
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Surrex, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

External mastic in Surrex: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Layer Marney Tower (about 5 miles south-east) are a reminder that the area around Surrex has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Honywood Community Science School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to St Peter ad Vincula include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Kelvedon station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
