Outside joints around Staple
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Goodnestone Park (about 1.9 miles south-west) nearby, there’s older building stock in the area around Staple as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St James, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in Staple
Movement joints let brickwork, render and cladding expand and shrink without cracking. 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 are dealing with rain getting behind render or cladding at a joint and old sealant gone brittle and cracked, we can help, on joints between brick and frames, brickwork movement joints and concrete & block alike.
External sealant needs dry, clean surfaces, so work around Staple is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Every job is covered by our 12-month guarantee.

What else we do in Staple
Landlord and commercial work in Staple
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Copings & trims
- Brickwork movement joints

Do you need external mastic in Staple?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
For landlords with property near Adisham station, outside joints that have cracked can let damp into a rental, so check them between lets.

Should I try it myself first?
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.
Some sealant jobs are within reach of a careful DIYer, 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.
FAQs for Staple
Will you come out to Staple?
Yes, smaller places are covered as well as towns. 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 Adisham station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep movement joints as flexible joints, not mortar
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Have failed joints looked at early
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
What happens on the day
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. For a village or hamlet like Staple, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Clear the area around the work
- Mention any tricky access
- Mention any sign-in or site rules at work premises
