Construction mastic in Kemptown
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. Most enquiries involve frame gaps too wide for sealant alone and sanitary sealant damaged by following trades, on window and door perimeters, sanitary and kitchen joints and cladding and panel joints. For commercial sealant work in Kemptown, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around places like Kemptown, a lot of construction is the conversion of older buildings, 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.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Brief the final clean team to avoid blades near sealant
- Bring the mastic contractor in after the last trades are through
- Keep product details for future maintenance
- Ask for joint and product checks before the package is urgent
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.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use.

Related advice
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Damage to finishes by other trades after we have sealed
- Frame gaps too wide for sealant, which the installer needs to correct
- Specifying the product where the designer hasn’t
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.

When to call us in Kemptown
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
These are often picked up first by site or facilities staff:
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
- Internal caulk splitting as the building dries out
- Different trades sealing to different standards
Recladding or extending a unit at a site like Bell Tower Industrial Estate, under half a mile to the east of Kemptown, brings panel joints and frame perimeters into the programme.

Your questions answered
Is Kemptown too small for you to travel to?
No. Places such as Kemptown are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does the sea air around Kemptown 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.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Is the mastic package guaranteed?
The work is guaranteed for 12 months, covering how we sealed. Keeping other trades off finished joints prevents most problems.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we will plan applicators around it.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The total length or number of joints
- Whether old sealant has to be cut out first
- Any access equipment needed
- Site requirements such as inductions and permits
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
However big the job, the same details help:
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
- Specification clauses that apply
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Sites and facades in and around Kemptown
Kemptown sits close to the coast, within about 1 mile. 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. There are a good number of hotels within about 2 miles of Kemptown. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Hospital estates such as Eye Hospital (to the north-west of Kemptown) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors on a campus like University of Brighton Moulesecoomb Campus, 1.9 miles north of Kemptown, facade and perimeter sealing has to fit around students and term dates.
