External mastic in Puddledock, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. Typical jobs include sealant pulling away from one side of the joint and movement joints with cracked, split or missing sealant, on joints between brick and frames, brickwork movement joints and concrete & block.
Outside work in London starts with access: side passages, upper floors and where to park. In Puddledock, joints up high may need ladders or other access, which is worth talking through when you book.
There’s a 12-month guarantee on every job, whatever its size.

Can I do it myself?
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. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
External mastic in Puddledock: local notes
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 Chartwell (about 0.6 miles north-west) are a reminder that the area around Puddledock has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Holy Trinity Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Puddledock is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Rented homes near Edenbridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Keep water from gutters off the wall
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
FAQs for Puddledock
Is parking a problem for a job in Puddledock?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you cover Puddledock for external mastic?
Yes. Our work covers London and the South East, and Puddledock is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
What we do, step by step
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 anything from a few hours to several days, depending on the building. In Puddledock, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Puddledock.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
