External mastic in Stelling Minnis
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include damp patches traced to an open external joint and leaking joints around cladding and façade panels, on brickwork movement joints, façade panels and render & cladding joints.
Around Stelling Minnis, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Why act early in Stelling Minnis
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Stelling Minnis, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What else we do in Stelling Minnis
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Stelling Minnis, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Common problems we fix in Stelling Minnis
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Gaps where render, brick and frames meet
For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What the job involves on each surface
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.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
Questions from Stelling Minnis
Is Stelling Minnis within the area you cover?
Yes, Stelling Minnis is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with external mastic in Stelling Minnis?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before work begins from the range available.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
