How we handle external mastic in Stuppington
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We are often asked to deal with old sealant gone brittle and cracked and gaps where render, brick and frames meet, on render & cladding joints, brickwork movement joints and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Stuppington is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Each job carries a 12-month guarantee, large or small.

Stuppington buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Nicholas, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Simon Langton Grammar School for Boys, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Canterbury East station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Why act early in Stuppington
A low-modulus sealant is chosen because it moves without pulling hard at the 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 Stuppington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

We also work for property managers and facilities teams in Stuppington and across Kent. Several sites can go on one quote, and we’re fully insured for the work.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Aftercare tips
To keep the joints looking good and working properly:
- Keep water from gutters off the wall
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
How it works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In a small place like Stuppington, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Tell us about any water getting in
