External mastic in Acol
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on brickwork movement joints, concrete & block and façade panels, and the jobs we see most are joints with sealant missing in places and rigid filler in a joint that should flex.
Older homes in small places like Acol may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Whatever the size of the job, it’s backed by our one-year guarantee.

Do you need external mastic in Acol?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Movement joints with cracked, split or missing sealant
For landlords with property near Birchington-On-Sea station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Whether VAT is included
- What product goes in the joint
- When the joint can take water or movement
What else we do in Acol
Aftercare tips
So the new joints stay in good condition:
- Make sure movement joints aren’t pointed over
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Once a joint cannot move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What affects the quote in Acol
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- Any mould that needs treating
- Any working-time requirements on site
- The type of sealant required
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
Need a quote? Please call 0345 464 0079 or drop us an email with a few details. We’ll explain what we’d do and give you a clear price before work begins.
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Acol, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
External mastic in Acol: local notes
Acol is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Birchington Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as St Mildreds Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Surface by surface
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.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Your questions about external mastic in Acol
Does living near the coast affect external mastic in Acol?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Birchington-On-Sea station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
