External mastic in Beltinge
On houses, flats and commercial buildings across Beltinge, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on copings & trims, joints between brick and frames and render & cladding joints, and people most often call us about damp patches traced to an open external joint and gaps where render, brick and frames meet.
In and around Beltinge, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Big or small, you get the same one-year guarantee.

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before we start. Most jobs take anything from a few hours to several days, depending on the building. A visit to Beltinge is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

What external mastic looks like in Beltinge
Beltinge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Reculver Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Herne Bay station, split movement joints are easy to miss on a rental until damp shows inside.

FAQs for Beltinge
Can you help a landlord with a rental near Herne Bay station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is external mastic in a coastal place like Beltinge any different?
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 work at height?
Each building is different. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Homes in smaller places like Beltinge can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

When to call us in Beltinge
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The problems people usually mention when they call are:
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Rigid filler in a joint that should flex
- Failed sealant between panels on a façade
For an older house near a landmark such as Church of St Bartholomew, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- Who does the work, and how experienced they are
- How hidden problems are handled
- What product goes in the joint
- How long to leave it before use
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
