External & façade joints in Broadwater, West Sussex
External mastic across Broadwater and nearby, with old sealant always removed completely.
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
Broadwater buildings and the weather
Broadwater is within about 2 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. With historic houses such as Ecclesden Manor (about 4.2 miles west) nearby, there’s older building stock in the area around Broadwater as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Broadwater CofE Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Worthing station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around St. Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

External mastic in Broadwater, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on concrete & block, copings & trims and joints between brick and frames, and common reasons people get in touch are brick movement joints where the sealant has split and failed sealant between panels on a façade.
In a smaller place like Broadwater, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
All our work is covered by our 12-month guarantee.

What else we do in Broadwater
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Point out the joints to other trades
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Landlords, agents and businesses in Broadwater
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

Surface by surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Damp that isn’t coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Broadwater: your questions answered
Is external mastic in a coastal place like Broadwater any different?
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.
Do you work for landlords with property near Worthing station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you come to Broadwater?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Broadwater.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. In a smaller place like Broadwater, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
