External Mastic in Seawick
Problem with your movement joints in Seawick? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Water getting into walls through failed joints
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
What we’re called out for in Seawick
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
If you can see any of these, it’s time to have the joints looked at:
- Failed seals between different materials
- Old sealant gone brittle and cracked
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
Letting a property close to Clacton-On-Sea station? Then split movement joints are easy to miss on a rental until damp shows inside.

External mastic for homes and businesses in Seawick
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on copings & trims, façade panels and brickwork movement joints, and people most often call us about movement joints with cracked, split or missing sealant and joints where the bead has come unstuck.
Somewhere as small as Seawick, 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.
Whatever the size of the job, you get the same 12-month guarantee in Seawick and across Essex.

Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind and protects the render itself.

DIY sealant or a professional job?
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, and the work is guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

FAQs for Seawick
I let a flat near Clacton-On-Sea station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Seawick?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
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 does not draw the eye.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height and we will confirm how they can be reached safely.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Outside joints around Seawick
Seawick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Tendring Enterprise Studio School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Seawick, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky
