Landlord and commercial work in East Malling
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
External mastic for homes and businesses in East Malling
On houses, flats and commercial buildings across East Malling, 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 are often asked to deal with joints with sealant missing in places and panel joints letting water in, on façade panels, render & cladding joints and brickwork movement joints.
Houses in smaller places like East Malling can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
A one-year guarantee comes as standard.

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a smaller place like East Malling, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. In a smaller place like East Malling, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

External mastic in East Malling: local notes
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. With historic houses such as Starkey Castle (about 4.9 miles north) nearby, there’s older building stock in the area around East Malling as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as St James the Great Academy, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near East Malling station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in East Malling
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Any of these means the joints need attention:
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
Homes close to Church of St James include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- How the joint is cleaned and prepared
- What insurance they hold
- Whether they seal over old material or remove it
- How long the guarantee is
Looking after it afterwards
To keep the joints looking good and working properly:
- Deal with leaking gutters that soak the joints below
- Walk round the building once a year and look at the joints
- Don’t let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Can I do it myself?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
