External mastic in Elmstone, done properly
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. Typical jobs include joints pointed up with cement by mistake and damp patches traced to an open external joint, across façade panels, concrete & block and brickwork movement joints.
Older homes in small places like Elmstone may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job.

Elmstone questions
Can you help a landlord with a rental near Minster station?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Elmstone?
Yes, Elmstone is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Elmstone.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Signs you need external mastic in Elmstone
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
Homes close to Elmstone Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Elmstone: local notes
Historic houses like Goodnestone Park (about 3.9 miles south) are a reminder that the area around Elmstone 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Preston Primary School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Minster station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Elmstone, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts

How we quote for external mastic
For a quick quote, just ask. What matters most is:
- Access and height
- The size of the job
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- A few pictures by email, if you can
- How we’d reach the joints
- Where the property is
We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Where a wall is exposed, as many are in small places like Elmstone, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
