Facade sealing for Hangleton sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.
Facade sealing in Hangleton, done properly
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on cladding panel joints, shopfront frames and window and door perimeters, and the failures we are asked to look at most are failed sealant on precast panel joints and staining on stone next to old sealant.

Conversions around smaller places like Hangleton 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, in a colour the planners or architect are happy with.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Check the asbestos register before old mastic is disturbed
- Keep sills, gutters and drainage paths clear
- Keep the sealant details on the building file
- Never let anyone seal over old sealant
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Work in places the size of Hangleton is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

Facade sealing in Hangleton: the local picture
Hangleton sits close to the coast, within about 2 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Hangleton is about 45 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.
On a campus such as University of Brighton Moulesecoomb Campus, which lies east of Hangleton, new teaching buildings and residences are normally built and refurbished around the academic year. Projects at schools like Hangleton Primary School work to term dates, so mastic is programmed tightly.

Common questions from Hangleton clients
Could you schedule work at a campus like University of Brighton Moulesecoomb Campus for the vacation?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a hospital such as Mill View Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Signs you need facade sealing in Hangleton
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.
It’s worth sending us details if you spot any of the following:
- Facade joints cracked through the middle
- Leaks at window and door perimeters
- Draughts around frames and panels
- Hard, chalky sealant that no longer flexes
New units and refits on sites such as Portland Road Trading Estate (1 mile south of Hangleton) need their panel and perimeter joints sealed to the specification.
Comparing quotes
- Proof of insurance
- Will RAMS and insurance details be available?
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
