External & façade joints in Bonnington, Kent
Our applicators work in Bonnington on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In a small place like Bonnington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- 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.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Mention any sign-in or site rules at work premises

Advice
How we handle external mastic in Bonnington
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 matching colour. If you’re dealing with joints pointed up with cement by mistake and damp patches traced to an open external joint, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Bonnington is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our one-year guarantee.

What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Bonnington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on

What we are called out for in Bonnington
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
Common reasons people contact us include:
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
Homes close to Church of St Rumwold include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
What to look for in a quote
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
- Whether you can choose the colour
- How much experience the applicator has
Different surfaces, different methods
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Common questions in Bonnington
Can you help a landlord with a rental near Ham Street station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Do you cover smaller places like Bonnington?
Yes. Bonnington 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 new sealant go over the old?
No, because it fails. The old sealant always comes out first.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Walls and rooflines in Bonnington
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. With historic houses such as Westenhanger Castle (about 4.4 miles east) nearby, there’s older building stock in the area around Bonnington 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.
For landlords with property near Ham Street station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Aldington Primary School, its movement joints, gutters and trims need looking after like any other building’s.
