External mastic for homes and businesses in Whatlington
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. Common call-outs are for panel joints letting water in and rigid filler in a joint that should flex, across façade panels, render & cladding joints and brickwork movement joints.
In a village or hamlet like Whatlington, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Questions from Whatlington
Can you do external mastic in Whatlington?
Yes, Whatlington is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you help a landlord with a rental near Battle station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall and the joint fails. If it has already been filled, we can normally cut it out and reseal it.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Leave the joints unpainted unless we have said otherwise
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
- Look over the joints every year, ideally after winter
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
When to call us in Whatlington
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
It’s worth asking for a quote if you see:
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Leaking joints around cladding and façade panels
- Moss and dirt in joints with no sealant left
Homes close to St Mary Magdalene's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book
- How much experience the applicator has
- What preparation is included
- What happens if they find a problem under the old sealant
- What product goes in the joint
Whatlington buildings and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Durhamford Manor (about 0.6 miles east) nearby, there’s older building stock in the area around Whatlington 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.
For site and facilities teams at buildings such as Vinehall School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Battle station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Different surfaces, different methods
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.

What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Whatlington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- 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.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
