External mastic in Mottisfont, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you’re dealing with leaking joints around cladding and façade panels and weeds or debris growing in open joints, we can help, whatever the surface.
Somewhere as small as Mottisfont, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Your job is guaranteed for a year, as with all our work.

Mottisfont buildings and the weather
With historic houses such as Mottisfont Abbey (about 0.2 miles north-east) nearby, there’s older building stock in the area around Mottisfont as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- Mould in or behind the old joints
- The type of sealant required
- Working hours on commercial sites
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

How the job changes by surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Mottisfont questions
Do you cover Mottisfont for external mastic?
Yes. Our work covers London and the South East, and Mottisfont is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is Mottisfont within the area you cover?
Yes. Mottisfont 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 have insurance?
Yes, we are fully insured for domestic and commercial work.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere as small as Mottisfont, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
