About our external mastic in Stone Hill
On houses, flats and commercial buildings across Stone Hill, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Typical jobs include movement joints filled with mortar instead of sealant and joints where the bead has come unstuck, on joints between brick and frames, façade panels and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Stone Hill is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our one-year guarantee in Stone Hill and across Kent.

Common problems we fix in Stone Hill
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Most people get in touch when they notice something like this:
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Stone Hill 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.
- Failed sealant is removed back to clean, sound faces.
- 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
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Stone Hill buildings and the weather
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 Westenhanger Castle (about 2.2 miles south-east) are a reminder that the area around Stone Hill has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Westenhanger station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Sellindge Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

How much does external mastic cost in Stone Hill?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Are you insured?

Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Stone Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
