External Mastic in East Chiltington
Problem with your movement joints in East Chiltington? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Joints pointed up with cement by mistake
- Joints with sealant missing in places
- Damp patches traced to an open external joint
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
External mastic in East Chiltington
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on joints between brick and frames, concrete & block and render & cladding joints, and the jobs we see most are leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render.
Somewhere as small as East Chiltington, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When something else is needed
It helps to know what we can’t do too:
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere like East Chiltington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Advice
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Do not let climbing plants root in the sealant
- Have failed joints looked at early
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Walls and rooflines in East Chiltington
Historic houses like Anne of Cleves House (about 4.3 miles south-east) are a reminder that the area around East Chiltington has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Plumpton station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Plumpton Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as The Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

FAQs for East Chiltington
I let a flat near Plumpton station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is East Chiltington within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job.
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 needs a flexible seal, not mortar.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Around East Chiltington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
