External mastic in Stoke D'Abernon, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. We are often asked to deal with joints with sealant missing in places and weathered mastic that no longer stretches, across joints between brick and frames, concrete & block and façade panels.
Somewhere as small as Stoke D'Abernon, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
A 12-month guarantee comes as standard.

What external mastic looks like in Stoke D'Abernon
Historic houses like The Homewood (about 2 miles north) are a reminder that the area around Stoke D'Abernon has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Parkside School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Cobham & Stoke Dabernon station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Stoke D'Abernon
Is Stoke D'Abernon in your area for external mastic?
Yes. Our work covers London and the South East, and Stoke D'Abernon is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Stoke D'Abernon?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Older cottages and farmhouses around Stoke D'Abernon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
- Make sure movement joints are not pointed over
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
What sealant work can’t fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

How the visit works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Stoke D'Abernon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Clear items away from the joints we’re working on
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Different surfaces, different methods
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
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
