About our external mastic in Shepway
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. Typical jobs include brick movement joints where the sealant has split and movement joints filled with mortar instead of sealant, on brickwork movement joints, render & cladding joints and façade panels.
Around Shepway, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
Whatever the size of the job, you get the same one-year guarantee in Shepway and across Kent.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have 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. For a job in Shepway, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
How to get a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Advice
Signs you need external mastic in Shepway
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
People generally contact us when they notice one of these:
- Panel joints letting water in
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
In the older streets around St Martin's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before you book

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Homes in smaller places like Shepway 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.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.

Walls and rooflines in Shepway
With historic houses such as Stoneacre (about 1.4 miles east) nearby, there’s older building stock in the area around Shepway as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, 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 Maidstone West station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Greenfields Community Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.

Surface by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check external joints each spring
- Show decorators and builders where the movement joints are
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
