Lynsore Bottom questions
Is Lynsore Bottom within the area you cover?
Yes. Lynsore Bottom is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Bekesbourne station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How long does the job take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll tell you how long to expect.
How do I get a quote for external mastic in Lynsore Bottom?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
About our external mastic in Lynsore Bottom
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint, we can put it right.
Somewhere as small as Lynsore Bottom, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What external mastic looks like in Lynsore Bottom
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Bekesbourne station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What we’re called out for in Lynsore Bottom
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
For an older house near a landmark such as Church of St Peter and St Paul, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
- What product goes in the joint
- Whether they seal over old material or remove it
- What preparation is included
- Whether you can choose the colour
Quotes for external mastic in Lynsore Bottom
You’ll get a clear quote before we start. It takes into account:
- Any mould that needs treating
- When we can work, for business premises
- How many areas need sealing
- The number and length of the joints
Leaving a failed joint generally 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 drop us an email and we’ll give you an honest view and a quote.

Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Render & cladding joints
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Lynsore Bottom, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Lynsore Bottom can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
