External mastic in South Street, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. If you are dealing with rigid filler in a joint that should flex and weeds or debris growing in open joints, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around South Street is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, you get the same one-year guarantee.

Other services in South Street
Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Common problems we fix in South Street
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
The problems people normally mention when they call are:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
Rented homes near Selling station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- How long the guarantee is
- Whether VAT is included
- Is the old sealant removed completely?
- Who turns up on the day
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Damp that is not coming from the joint
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like South Street, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Your questions about external mastic in South Street
Will you come out to South Street?
Yes. South Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover South Street for external mastic?
Yes. Our work covers London and the South East, and South Street is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
External mastic in South Street: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Belmont House and Gardens (about 4.4 miles west) are a reminder that the area around South Street 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.
Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How we quote for external mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- When we can work, for business premises
- The product the joint needs
- Whether old sealant or filler has to be cut out
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
There’s no need for technical detail. Just tell us:
- A few photos by email, if you can
- Where the property is
- How we’d reach the joints
- Roughly how big the job is
