How it works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Abbotsford, 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 walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on

How we handle external mastic in Abbotsford
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. Typical jobs include sealant pulling away from one side of the joint and damp patches traced to an open external joint, on façade panels, brickwork movement joints and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Abbotsford is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work comes with our 12-month guarantee, wherever you are in West Sussex.

When something else is needed
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
- Copings & trims
- Façade panels
- Render & cladding joints
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Abbotsford buildings and the weather
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. Historic houses like Ockenden Manor (about 2.3 miles north) are a reminder that the area around Abbotsford 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.
For an older house near a landmark such as St Edward the Confessor, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as St Paul's Catholic College, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Wivelsfield station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
- 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.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.

Quotes for external mastic in Abbotsford
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Abbotsford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Abbotsford: your questions answered
Can you do external mastic in Abbotsford?
Yes, Abbotsford is within the area we cover. We work across London and the South East. Just call 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 Wivelsfield station?

What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start from the range available.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
