External mastic for homes and businesses in Fairlight
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with plants rooting in failed movement joints and cracked joints where brick meets render or frames, across copings & trims, render & cladding joints and joints between brick and frames.
Older homes in small places like Fairlight may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

How we quote for external mastic
Every job gets its own quote. This is what makes a difference:

Helping us quote
Photos help, but a description is a good start. Please mention:
- The type of property
- If someone has resealed it before
- Where the property is
- How we’d reach the joints

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Fairlight, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

When something else is needed
A few problems are outside what sealant work can do:
- Damp that isn’t coming from the joint
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.

Signs you need external mastic in Fairlight
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Most people get in touch when they notice something like this:
- Failed seals between different materials
- Movement joints filled with mortar instead of sealant
- Failed sealant between panels on a façade
- Brick movement joints where the sealant has split
For site and facilities teams at buildings such as The Hastings Academy, its movement joints, gutters and trims need looking after like any other building’s.

Walls and rooflines in Fairlight
Fairlight 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Parish Church of St Andrew include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Three Oaks station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
