About our external mastic in Elmstead
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on joints between brick and frames, concrete & block and copings & trims, and the jobs we see most are plants rooting in failed movement joints and panel joints letting water in.
Somewhere as small as Elmstead, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months.

Different surfaces, different methods
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Look over the joints every year, ideally after winter
- Leave the joints unpainted unless we’ve said otherwise
- Avoid pressure-washing directly into sealant joints
- Keep water from gutters off the wall
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
When something else is needed
Before booking, it’s worth knowing the limits:
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
- Cracked brickwork or render that needs a builder or plasterer
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- How many areas need sealing
- Whether there’s mould to deal with
- Any working-time requirements on site
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. Your quote takes all of that into account.

FAQs for Elmstead
I let a flat near Wivenhoe station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Elmstead?
Yes, Elmstead is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Elmstead, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any tricky access
- Tell us about any water getting in

Advice
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a small place like Elmstead, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Elmstead buildings and the weather
Elmstead is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Wivenhoe station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Broomgrove Junior School? Then its movement joints, gutters and trims need looking after like any other building’s.
