Your questions about external mastic in Abbotts Barton
Do you work for landlords with property near Winchester station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Abbotts Barton in your area for external mastic?
Yes. Our work covers London and the South East, and Abbotts Barton is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. We’ll reseal it with a flexible sealant.
Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.
How we handle external mastic in Abbotts Barton
On houses, flats and commercial buildings across Abbotts Barton, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on copings & trims, concrete & block and façade panels, and the jobs we see most are joints pointed up with cement by mistake and brick movement joints where the sealant has split.
In and around Abbotts Barton, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Big or small, it’s backed by our 12-month guarantee.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why it’s worth doing now in Abbotts Barton
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In a smaller place like Abbotts Barton, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Avoid pressure-washing directly into sealant joints
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Walls and rooflines in Abbotts Barton
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.
For an older house near a landmark such as St Bartholomew's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as St Bede Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What we’re called out for in Abbotts Barton
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 cannot stretch and tears as soon as the joint widens.
Keep an eye out for these signs:
- Hard, crazed mastic that has stopped moving
- Failed seals between different materials
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
If you let a flat or house near Winchester station, outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. A visit to Abbotts Barton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
