About our construction mastic in Upperton
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you are dealing with sealant knocked or painted over by other trades and internal caulk splitting as the building dries out, we can help. Looking for mastic applicators who cover Upperton? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Conversions around smaller places like Upperton often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
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.

Common problems we fix in Upperton
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Clients normally get in touch after noticing one or more of the following:
- Bath and shower joints scraped during the final clean
- Oversized or tapered gaps around new frames
- Missed perimeter joints on a new elevation
- Old sealant on a refurbishment that needs stripping before new work
On a healthcare site such as Eastbourne District General Hospital (0.8 miles north of Upperton), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote

Surface by surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a job in Upperton, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Agree which areas must stay open
- Tell us what induction or permit system the site runs

Facades, frames and programmes in Upperton
Upperton sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. A 2-mile radius around Upperton takes in plenty of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For a contractor at a hotel such as Savoy Court Hotel, 0.9 miles to the south-east of Upperton, the mastic often has to be finished before a reopening date. Projects at colleges like East Sussex College Eastbourne (1 mile north of Upperton) tend to run to term dates, so the mastic is planned tightly.

What we can’t put right

- Rework caused by others damaging completed areas
- Frames fitted out of tolerance

FAQs: Upperton
Can you work at a site such as Courtlands Road Industrial Estate, by Upperton?
Yes, sites like Courtlands Road Industrial Estate are within our area, along with the rest of Upperton. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you work around term dates at a campus such as University of Brighton Eastbourne Campus?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What will the job cost?
Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email us with a description of the work.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What happens if the weather stops external sealing?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Why it’s worth doing now in Upperton
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. In a smaller place such as Upperton, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
