External Mastic in Jaywick
Professional external mastic in and around Jaywick, with old sealant always removed completely and a one-year guarantee.
- Sealant pulling away from one side of the joint
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
Why deal with it now?
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. A stiffer product can damage the joint edge as it fails. Around Jaywick, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

About our external mastic in Jaywick
For buildings in Jaywick, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have rain getting behind render or cladding at a joint and joints with sealant missing in places, we can help, on render & cladding joints, joints between brick and frames and concrete & block alike.
Homes around Jaywick range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Jaywick questions
Do you work for landlords with property near Clacton-On-Sea station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Does living near the coast affect external mastic in Jaywick?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only.

What else we do in Jaywick
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act on the first splits you see
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Don’t let climbing plants root in the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- Joints between brick and frames
- Concrete & block

What affects the quote in Jaywick
Every job gets its own quote. This is what makes a difference:
- How many areas need sealing
- Any mould that needs treating
- When we can work, for business premises
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
For a quote, call 0345 464 0079 or email us with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes anything from a few hours to several days, depending on the building. In a smaller place like Jaywick, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.
Advice
Outside joints around Jaywick
Jaywick is within about 1 mile of 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Clacton-On-Sea station, split movement joints are easy to miss on a rental until damp shows inside. For site and facilities teams at buildings such as Sir Martin Frobisher Academy, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Christopher, older walls, gutters and the joints where extensions meet them need a flexible sealant.
