External mastic in Langenhoe, done properly
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on brickwork movement joints, render & cladding joints and concrete & block, and common reasons people get in touch are weeds or debris growing in open joints and failed seals between different materials.
External sealant needs dry, clean surfaces, so work around Langenhoe is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You get a one-year guarantee, the same in Langenhoe as everywhere else we work.

Do you need external mastic in Langenhoe?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Look out for these signs:
- Joints with sealant missing in places
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Weeds or debris growing in open joints
Schools such as Langenhoe Community Primary School and Pre-School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Langenhoe buildings and the weather
Langenhoe is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Layer Marney Tower (about 4.9 miles west) nearby, there’s older building stock in the area around Langenhoe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Andrew, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Wivenhoe station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What sealant work cannot fix

- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Render that’s blown, hollow or coming away

Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Langenhoe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
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.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Somewhere like Langenhoe 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Clear the area around the work

FAQs for Langenhoe
Does living near the coast affect external mastic in Langenhoe?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Langenhoe?
Yes. Langenhoe is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. We’ll reseal it with a flexible sealant.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
