Walls and rooflines in Brightlingsea
Brightlingsea is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. 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.
In the older streets around Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Alresford station, split movement joints are easy to miss on a rental until damp shows inside.

External mastic for homes and businesses in Brightlingsea
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and common reasons people get in touch are weeds or debris growing in open joints and gaps where render, brick and frames meet.
Houses in smaller places like Brightlingsea can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Questions from Brightlingsea
Do you work for landlords with property near Alresford station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is external mastic in a coastal place like Brightlingsea any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
When will the joints need doing again?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Aftercare tips
So the new joints stay in good condition:
- Check the sealant is paintable before painting near it
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
- Avoid pressure-washing directly into sealant joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Landlords, agents and businesses in Brightlingsea
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Surface by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Common problems we fix in Brightlingsea
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Weeds or debris growing in open joints
Managing a site like Brightlingsea Primary School and Nursery? Then larger buildings have long runs of movement joint that eventually need resealing.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. A visit to Brightlingsea is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Related advice
Why act early in Brightlingsea
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. In an older home around Brightlingsea, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
