Contractors’ notes for Broadwater
Broadwater lies within about 2 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Broadwater is about 48 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Further education sites such as Northbrook College (to the south of Broadwater) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotels like The Railway Hotel (to the south of Broadwater) rarely close for long, so refurbishment mastic is phased floor by floor.
Broadwater is about 1 mile east of Worthing, in West Sussex. Across the BN14 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Construction mastic in Broadwater
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can normally carry on while the outside waits. We work on window and door perimeters, floor and skirting junctions and internal decorators’ caulk, and what we’re called in for most is new external sealant already peeling away and existing joints on a refurb that need cutting out and resealing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Broadwater, that means joint design, primers and backing rod as standard.
Conversions around smaller places like Broadwater often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
- Glazing units that are cracked or misted
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Common questions from Broadwater clients
Is Broadwater too small for you to travel to?
No. Places such as Broadwater are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work around term dates at a campus such as Northbrook College?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you come in just for snagging?
Yes. We clear snags by redoing joints rather than patching them, working to your handover date.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Does weather affect external mastic work?
External mastic depends on conditions: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Several jobs near Broadwater can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Explain the parking and delivery arrangements
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Related advice
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Use the product the specification names
- Share drawings and the specification as soon as possible
- Don’t schedule sealing before decorators and flooring are done
- Ask cleaners to use soft cloths around fresh sealant
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.
Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. For buildings in places like Broadwater, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Common problems we fix in Broadwater
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
Things that typically lead to an enquiry:
- External joints sealed in damp or cold conditions that are now failing
- Sealant knocked or painted over by other trades
- Inconsistent sealant finishes from plot to plot
- Oversized or tapered gaps around new frames
For a contractor working at a hospital such as Worthing Hospital (0.9 miles south-east of Broadwater), perimeter and facade sealing is planned around patients and deliveries.
