External mastic for homes and businesses in East Preston
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on concrete & block, render & cladding joints and joints between brick and frames, and common reasons people get in touch are weeds or debris growing in open joints and movement joints with cracked, split or missing sealant.
Houses in smaller places like East Preston can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Outside joints around East Preston
East Preston 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. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Ecclesden Manor (about 1.3 miles north) nearby, there’s older building stock in the area around East Preston as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Angmering station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as East Preston Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Common questions in East Preston
I let a flat near Angmering station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Does living near the coast affect external mastic in East Preston?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. 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 East Preston 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Advice
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Where we work in East Preston
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
- Façade panels
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

When to call us in East Preston
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
The problems people usually mention when they call are:
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
If you live in an older home near The Parish Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask before painting over external sealant
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
- Act on the first splits you see
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
