External mastic in Hangleton
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on joints between brick and frames, concrete & block and copings & trims, and common reasons people get in touch are plants rooting in failed movement joints and old sealant gone brittle and cracked.
Somewhere as small as Hangleton, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why act early in Hangleton
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Around Hangleton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.

Common problems we fix in Hangleton
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
People usually contact us after spotting something like this:
- Joints where the bead has come unstuck
- Water getting into walls through failed joints
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
For an older house near a landmark such as St Andrew's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- How long the guarantee is
- Whether all the old sealant comes out first
- How long to leave it before use

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Hangleton: your questions answered
Is Hangleton within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Hangleton any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
How long does external mastic take?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. We’ll confirm how long when we quote.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What happens on the day
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Hangleton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

External mastic in Hangleton: local notes
Hangleton is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Ecclesden Manor (about 0.9 miles north-west) nearby, there’s older building stock in the area around Hangleton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Ferring CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Goring-By-Sea station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
- Don’t let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
