How we handle external mastic in Weston Otmoor
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We are often asked to deal with rigid filler in a joint that should flex and failed sealant between panels on a façade, across copings & trims, façade panels and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Weston Otmoor is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, in Weston Otmoor and everywhere else we cover.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building in most cases. For a village or hamlet like Weston Otmoor, 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.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Weston Otmoor: your questions answered
Is Weston Otmoor in your area for external mastic?
Yes, Weston Otmoor is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Islip station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Is it OK to fill a movement joint with cement?
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.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Show decorators and builders where the movement joints are
- Fix overflowing gutters above sealed joints
- Keep high-pressure jets off the joints
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Movement that is more than a sealant joint can take
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

What affects the quote in Weston Otmoor
You will get a clear quote before we start. It takes into account:
- How easy the joints are to reach
- How many areas need sealing
- Any mould that needs treating
- The product the joint needs
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
What to tell us for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Where the property is
- How we’d reach the joints
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common problems we fix in Weston Otmoor
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Plants rooting in failed movement joints
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
