How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In a small place like Brenchley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on

Advice
How we handle external mastic in Brenchley
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. We’re often asked to deal with joints with sealant missing in places and sealant pulling away from one side of the joint, on concrete & block, brickwork movement joints and render & cladding joints.
Somewhere as small as Brenchley, 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.
Your job is guaranteed for a year, as with all our work.

What external mastic looks like in Brenchley
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Scotney Castle (about 4.1 miles south) are a reminder that the area around Brenchley has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Parish Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Brenchley and Matfield Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

FAQs for Brenchley
Is Brenchley within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Paddock Wood station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Are you insured?
Yes, we’re fully insured for every job we do.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
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.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the 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.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Brenchley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Honest limits
We will always be straight with you, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Signs you need external mastic in Brenchley
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 can’t stretch and tears as soon as the joint widens.
The problems people usually mention when they call include:
- Failed seals between different materials
- Panel joints letting water in
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
Letting a property close to Paddock Wood station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
