How we handle external mastic in Out Elmstead
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. If you’re dealing with leaking joints around cladding and façade panels and joints where the bead has come unstuck, we can help.
In a village or hamlet like Out Elmstead, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Walls and rooflines in Out Elmstead
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. With historic houses such as Goodnestone Park (about 3.6 miles north-east) nearby, there’s older building stock in the area around Out Elmstead as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St Giles, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Aylesham station, outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the cost of external mastic
You’ll get a clear quote before we start. It takes into account:
- The old material and how stubborn it is
- The amount of work
- How many areas need sealing
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or drop us an email.
The process
There’s no need to move everything out before we come, 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 in most cases. Somewhere like Out Elmstead needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Move anything stored near the joints
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
What we’re called out for in Out Elmstead
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Most people get in touch after spotting something like this:
- Failed seals between different materials
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
If you look after a building such as Barham Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Landlords, agents and businesses in Out Elmstead
For anyone letting property in or around Out Elmstead, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.

Out Elmstead questions
Will you come out to Out Elmstead?
Yes, we do. 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.
I let a flat near Aylesham station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why act early in Out Elmstead
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Older cottages and farmhouses around Out Elmstead can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
