External mastic in Gambles Green, done properly
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 and we use one wherever it does. If you have weathered mastic that no longer stretches and weeds or debris growing in open joints, we can help, on brickwork movement joints, façade panels and copings & trims alike.
In a village or hamlet like Gambles Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How we quote for external mastic
You’ll get a clear quote before any work starts. It takes into account:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The number of rooms or windows
- The amount of work
A few things move the cost up or down: 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.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The rough size of the job
- Access, such as stairs, a lift or height
- If someone has resealed it before
- Whether it’s a home or a business
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.
Gambles Green questions
Is Gambles Green in your area for external mastic?
Yes. Our work covers London and the South East, and Gambles Green is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Hatfield Peverel station?
Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee.
Why do you put foam in the joint first?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Honest limits
New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:
- Cracked brickwork or render that needs a builder or plasterer
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
What we seal
- Render & cladding joints

Gambles Green buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Hatfield Peverel station? Then split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near United Reformed Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Terling Church of England Voluntary Aided Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What else we do in Gambles Green
Why it’s worth doing now in Gambles Green
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Gambles Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

- One-year guarantee on every job
- Neat joints and a tidy finish
- 20+ years of sealant experience
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Gambles Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

How to look after the new joints
So the new joints stay in good condition:
- Clear growth from the base of walls and joints
- Tell anyone working on the walls about the movement joints
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
