Bromley Cross External Mastic
We cover Bromley Cross for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
- Render that’s blown, hollow or coming away
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.

How we handle external mastic in Bromley Cross
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you’re dealing with cracked joints where brick meets render or frames and joints where the bead has come unstuck, we can help, on brickwork movement joints, render & cladding joints and façade panels alike.
External sealant needs dry, clean surfaces, so work around Bromley Cross is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

FAQs for Bromley Cross
Do you work for landlords with property near Manningtree 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’ll give you a fixed price before work begins.
Is Bromley Cross within the area you cover?
Yes. Bromley Cross is within the area we cover, which takes in towns, villages and rural addresses. 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 use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before we start from the range available.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
For anyone letting property in or around Bromley Cross, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Walk round the building once a year and look at the joints
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
- Fix overflowing gutters above sealed joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it.

What else we do in Bromley Cross
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common problems we fix in Bromley Cross
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Weathered mastic that no longer stretches
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
- Joints with sealant missing in places
If you let a flat or house near Manningtree station, outside joints that have cracked can let damp into a rental, so check them between lets.

What external mastic looks like in Bromley Cross
Historic houses like Castle House (about 2.9 miles north) are a reminder that the area around Bromley Cross has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Anne and St Lawrence include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
