Salvington questions
I let a flat near West Worthing station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Does living near the coast affect external mastic in Salvington?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is there a guarantee?
Yes. Every job comes with our one-year guarantee.
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 it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
How much does external mastic cost in Salvington?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
How we handle external mastic in Salvington
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. Common call-outs are for joints where the bead has come unstuck and failed seals between different materials, across concrete & block, brickwork movement joints and façade panels.
Houses in smaller places like Salvington 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. Joints on those sides are generally the first to go.
Your job is guaranteed for a year, as with all our work.

Landlord and commercial work in Salvington
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Housing providers, facilities teams and property managers book us too in Salvington and across West Sussex. Several sites can be quoted together, and we are fully insured for the work.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why it’s worth doing now in Salvington
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In an older home around Salvington, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

Looking after it afterwards
So the new joints stay in good condition:
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.
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.
Salvington buildings and the weather
Salvington is within about 3 miles 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. Historic houses like Ecclesden Manor (about 3.2 miles west) are a reminder that the area around Salvington has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near West Worthing station, outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Durrington Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the quote in Salvington
The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- How easy the joints are to reach
- How many areas need sealing
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The problem you’ve noticed
- Roughly how big the job is
- How we’d reach the joints
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. For a job in Salvington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Related advice
Signs you need external mastic in Salvington
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
If you can see any of these, it’s time to have the joints looked at:
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
- Failed sealant between panels on a façade
- Failed seals between different materials
In the older streets around St Symphorian's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What your quote should include
- Which colour the sealant will be
- Is the old sealant removed completely?
- Whether they’re fully insured
- How the joint is cleaned and prepared
