About our external mastic in Paynes Green
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include old sealant gone brittle and cracked and weeds or debris growing in open joints, across concrete & block, copings & trims and brickwork movement joints.
External sealant needs dry, clean surfaces, so work around Paynes Green is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our 12-month guarantee in Paynes Green and across Surrey.

When to call us in Paynes Green
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
- Joints where the bead has come unstuck
Letting a property close to Ockley station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before booking anyone
- What guarantee comes with the work
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Avoid pressure-washing directly into sealant joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere like Paynes Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Older cottages and farmhouses around Paynes Green 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. We take all of that into account in your quote.
Why book with us
- One-year guarantee on every job
- We agree the colour with you first
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels

Surface by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Failed render or damaged cladding panels
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
