External Mastic in Lingfield
External mastic across Lingfield and nearby, with old sealant always removed completely and a one-year guarantee.
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
How to look after the new joints
Aftercare is simple:
- Get split or bare joints resealed while the damage is small
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Keep high-pressure jets off the joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
External mastic in Lingfield
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you’re dealing with weathered mastic that no longer stretches and joints with sealant missing in places, we can put it right.
Around Lingfield, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
There’s a 12-month guarantee on every job.

We also work for property managers and facilities teams. We can quote a run of properties together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Around Lingfield, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

What else we do in Lingfield
Lingfield buildings and the weather
Historic houses like Hammerwood Park (about 4.5 miles south-east) are a reminder that the area around Lingfield 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Lingfield station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Lingfield Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of St Peter and St Paul include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

In total, it normally takes anything from a few hours to several days, depending on the building.

- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that’s easy
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the job is, and your postcode
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or email us and describe the job and send pictures if you have them.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
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.
Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
