How we handle construction mastic in Upchurch
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over. Sealing too early only means coming back once others have damaged it. We work on floor and skirting junctions, internal decorators’ caulk and window and door perimeters, and what we’re called in for most is external joints sealed in damp or cold conditions that are now failing and inconsistent sealant finishes from plot to plot. A single leaking joint is often how a building in Upchurch first comes to us: we look at the rest while we’re there and tell you what we find.
In the countryside around places like Upchurch, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product.
Common problems we fix in Upchurch
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Choosing the right product for each joint reduces that.
Common reasons buildings call us in:
- Snag items on joints that need redoing before handover
- Old sealant on a refurbishment that needs stripping before new work
- Internal caulk splitting as the building dries out
- A mastic package split between trades with no clear owner
Recladding or extending a unit at a site like Newington Industrial Estate, 1.6 miles to the south of Upchurch, brings panel joints and frame perimeters into the programme.
Before you book anyone
- Whether their applicators hold CSCS cards
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- How long is the guarantee, and what does it include?
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Sites and facades in and around Upchurch
Upchurch lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
When a school such as Holywell Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Extensions at sites like Medway Maritime Hospital (to the west of Upchurch) normally sit beside working departments, and the mastic follows strict access rules.

Advice
Upchurch: questions and answers
Does the sea air around Upchurch change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Could you schedule work at a campus like University of Greenwich - Medway for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What does a mastic package typically include?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
What’s the quickest route to a quote?

Aftercare for building managers
After handover, a little attention goes a long way:
- Release areas for mastic once other trades have finished in them
- Put any product change through the designer first
- Ask installers to correct oversized gaps first
- Protect sealed areas from following trades
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
