External mastic for homes and businesses in Wesley End
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. If you are dealing with joints pointed up with cement by mistake and old sealant gone brittle and cracked, we can put it right.
Somewhere as small as Wesley End, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a one-year guarantee.

What external mastic looks like in Wesley End
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hedingham Castle (about 4.8 miles south-east) nearby, there’s older building stock in the area around Wesley End as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In and around Wesley End, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. For an older house near a landmark such as Parish Church of St Peter and St Thomas, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Wesley End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What sealant work can’t fix
It helps to know what we cannot do too:
- Walls that need new movement joints cut into them
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on

- Render & cladding joints
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What else we do in Wesley End
The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as Wesley End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
- Let us know about parking restrictions

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep water from gutters off the wall
- Leave the joints unpainted unless we have said otherwise
- Point out the joints to other trades
- Keep movement joints as flexible joints, not mortar
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What affects the cost of external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- Whether the work is at height
- When we can work, for business premises
- Mould in or behind the old joints
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Common questions in Wesley End
Is Wesley End within the area you cover?

Is Wesley End in your area for external mastic?

Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
How much does external mastic cost in Wesley End?

Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
