External mastic in World's End
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We work on brickwork movement joints, façade panels and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in World's End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Work for landlords, hotels and businesses
For anyone letting property in or around World's End, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How the visit works
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. Most jobs then take anything from a few hours to several days, depending on the building. For a village or hamlet like World's End, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- 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 parking rules near the property
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Your questions about external mastic in World's End
Is World's End within the area you cover?
Yes, World's End is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on external mastic in World's End?
All our work, in World's End and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Outside joints around World's End
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Beedon C.E. (Controlled) Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Around World's End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Do you need external mastic in World's End?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Panel joints letting water in
- Brick movement joints where the sealant has split
- Failed seals between different materials
- Old sealant gone brittle and cracked
For an older house near a landmark such as Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- What insurance they hold
- Whether all the old sealant comes out first
- When the joint can take water or movement
- Who turns up on the day

How to look after the new joints
To keep the joints looking good and working properly:
- Tell anyone working on the walls about the movement joints
- Wash walls gently around the sealant
- Have failed joints looked at early
- Keep water from gutters off the wall
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.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
