External mastic for homes and businesses in Malting Green
On houses, flats and commercial buildings across Malting Green, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you’re dealing with movement joints filled with mortar instead of sealant and hard, crazed mastic that has stopped moving, we can help, whatever the surface.
In a village or hamlet like Malting Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, it’s backed by our 12-month guarantee.

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Honest limits
In fairness, there are a few things sealant will not fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint

The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Malting Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Mention if the joints have been sealed before

What external mastic looks like in Malting Green
With historic houses such as Layer Marney Tower (about 3.7 miles south-west) nearby, there’s older building stock in the area around Malting Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
For site and facilities teams at buildings such as Alderman Blaxill School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Andrew, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What we’re called out for in Malting Green
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
These are the problems we’re asked about most:
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Joints where the bead has come unstuck
For landlords with property near Colchester Town station, outside joints that have cracked can let damp into a rental, so check them between lets.

Quotes for external mastic in Malting Green
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The type of sealant required
- The number and length of the joints
- The old material and how stubborn it is
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- Whether it has been sealed before
- Photos by email, if that is easy

Why act early in Malting Green
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around Malting Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.

How the job changes by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Malting Green questions
Do you cover Malting Green for external mastic?
Yes, Malting Green is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
I let a flat near Colchester Town station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin from the range available.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
How do I get a quote for external mastic in Malting Green?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
