Belmont buildings and the weather
Belmont is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Emmanuel Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Ore station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

External mastic in Belmont, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. Common call-outs are for damp patches traced to an open external joint and brick movement joints where the sealant has split, across render & cladding joints, brickwork movement joints and concrete & block.
In a smaller place like Belmont, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. In a smaller place like Belmont, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

Advice
FAQs for Belmont
Do you work for landlords with property near Ore station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Does the coastal weather in Belmont affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
How do you reach high-level joints?
It depends on the building. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
How do I get a quote for external mastic in Belmont?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Do you need external mastic in Belmont?
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The problems people generally mention when they call are:
- Plants rooting in failed movement joints
- Panel joints letting water in
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as Ark Castledown Primary Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- Whether the sealant suits the joint
- The length of the guarantee
- How the joint is cleaned and prepared
- Whether they’re fully insured
Why it’s worth doing now in Belmont
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. In a smaller place like Belmont, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- White, clear, grey or another colour, product permitting
- Approved under the ARBOMaster scheme
- We never seal over old sealant

When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Render that is blown, hollow or coming away
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Façade panels
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep high-pressure jets off the joints
- Deal with leaking gutters that soak the joints below
- Do not let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
