About our external mastic in Rotherfield
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for weathered mastic that no longer stretches and joints with sealant missing in places, across façade panels, brickwork movement joints and render & cladding joints.
Somewhere as small as Rotherfield, 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.
All our work comes with a 12-month guarantee, wherever you are in East Sussex.

Rotherfield questions
I let a flat near Crowborough station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Can you do external mastic in Rotherfield?
Yes. Our work covers London and the South East, and Rotherfield is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
What should I tell you?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Common problems we fix in Rotherfield
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
Schools such as Rotherfield Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
- The length of the guarantee
- How long to leave it before use
Surface by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Landlord and commercial work in Rotherfield
Whether it’s one flat or 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.
What affects the quote in Rotherfield
Call for a quick quote. What matters most is:
- When we can work, for business premises
- The number of rooms or windows
- Mould in or behind the old joints
- The amount of work
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
When you contact us, these details help:
- Photos by email, if that’s easy
- Any access issues, like height or stairs
- If someone has resealed it before
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Walls and rooflines in Rotherfield
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.
In the older streets around The Parish Church of St Denys, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Crowborough station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Rotherfield, 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.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
