What the job involves on each surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Marks Tey buildings and the weather
Historic houses like Layer Marney Tower (about 3.9 miles south) are a reminder that the area around Marks Tey 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Marks Tey station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. For a village or hamlet like Marks Tey, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

Common questions in Marks Tey
Is Marks Tey within the area you cover?
Yes. Marks Tey is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Marks Tey station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How long does the job take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation. Your quote will say how long we expect yours to take.
Can you reach joints on upper floors?
Each building is different. Tell us the height, the number of joints and what’s below them.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
When to call us in Marks Tey
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for any of the following:
- Plants rooting in failed movement joints
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
If you live in an older home near Church of St Andrew, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before booking anyone
- The length of the guarantee
- Who does the work, and how experienced they are
- Whether you can choose the colour
- What product goes in the joint
How to look after the new joints
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
