External mastic in Old Heath, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Common call-outs are for gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving, on façade panels, render & cladding joints and joints between brick and frames.
In and around Old Heath, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Old Heath questions
Does living near the coast affect external mastic in Old Heath?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Will you come out to Old Heath?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
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.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How we quote for external mastic
There’s no set price list. The quote depends on:
- How many areas need sealing
- Mould in or behind the old joints
- The product the joint needs
- Any working-time requirements on site
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Whether it’s a home or a business
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure movement joints are not pointed over
- Ask before painting over external sealant
- Point out the joints to other trades
- Have failed joints looked at early
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the building for a typical job. Parking around Old Heath is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Walls and rooflines in Old Heath
Old Heath is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
If you let a flat or house near Hythe station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as St Barnabas, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we are called out for in Old Heath
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
These are the problems we’re asked about most:
- Leaking joints around cladding and façade panels
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
For site and facilities teams at buildings such as Old Heath Community Primary School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
