External mastic for homes and businesses in Rottingdean
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are joints with sealant missing in places and weeds or debris growing in open joints.
External sealant needs dry, clean surfaces, so work around Rottingdean is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Rottingdean
Do you work for landlords with property near Moulsecoomb station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover smaller places like Rottingdean?
Yes, Rottingdean is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How do I get a quote for external mastic in Rottingdean?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Yes. All our work carries a one-year guarantee.
What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
What we seal
- Brickwork movement joints

What external mastic looks like in Rottingdean
Rottingdean is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Royal Pavilion (about 3.2 miles west) are a reminder that the area around Rottingdean has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Moulsecoomb station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around St Wulfran's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the visit works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Rottingdean, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Why act early in Rottingdean
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Around Rottingdean, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Why us?
- ARBOMaster approved applicator

What we’re called out for in Rottingdean
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
Look out for any of the following:
- Weathered mastic that no longer stretches
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
Managing a site like Longhill High School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Landlords, agents and businesses in Rottingdean
If you manage several properties in or around Rottingdean, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
