Folkington External Mastic
Our applicators work in Folkington on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
- Leaking joints around cladding and façade panels
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
How we handle external mastic in Folkington
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We work on façade panels, joints between brick and frames and render & cladding joints, and common reasons people get in touch are sealant pulling away from one side of the joint and weeds or debris growing in open joints.
Somewhere as small as Folkington, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee, whatever its size.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
How the visit works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as Folkington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about any water getting in
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

Advice
Questions from Folkington
Is Folkington within the area you cover?
Yes, Folkington is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Polegate station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Surface by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Signs you need external mastic in Folkington
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
- Rigid filler in a joint that should flex
For an older house near a landmark such as The Parish Church of Saint Peter, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- What happens if the job turns out different
- How long the guarantee is
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Folkington buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Alfriston Clergy House (about 2.5 miles west) nearby, there’s older building stock in the area around Folkington as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Polegate station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Willingdon Community School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Why act early in Folkington
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Older cottages and farmhouses around Folkington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
