Construction mastic in Patcham, done properly
The specification and the programme set the job rather than whatever product is to hand. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. If you are dealing with external joints sealed in damp or cold conditions that are now failing and cracks opening in caulked internal joints, we can put it right, whatever the surface. Most enquiries from Patcham start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For a contractor on a smaller site near Patcham, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How the job changes by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product.
Maintenance after handover
To get the most from the new sealant:
- Brief following trades on areas that have been sealed
- Don’t schedule sealing before decorators and flooring are done
- Stick to the specified sealant rather than a generic substitute
- Plan external elevations with the weather in mind
Any damage after we have finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
General trades versus a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
- Oversized gaps that need packing or adjustment by others
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.
Surfaces we seal
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Brick and block movement joints
- Internal decorators’ caulk
What we’re called out for in Patcham
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Look out for the following:
- Sealant knocked or painted over by other trades
- Old sealant on a refurbishment that needs stripping before new work
- Early adhesion failures on new external joints
- Perimeter gaps outside the sealant’s range
Recladding or extending a unit at a site like Hollingbury Industrial Estate (1.2 miles east of Patcham) brings panel joints and frame perimeters into the programme.
What to look for in a quote
- How they handle RAMS and site documents
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?

From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Patcham, the main thing is a clear picture of the work. A fixed quote follows.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- 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.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Tell us what induction or permit system the site runs
- For older buildings, check the asbestos register before work
- Warn occupants and staff about the work

Contractors’ notes for Patcham
Patcham lies within about 3 miles 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. Several hotels sit less than 2 miles from Patcham. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor working at a hospital such as The Montefiore Hospital, which lies south of Patcham, perimeter and facade sealing is planned around patients and deliveries. University estates such as University of Brighton Moulesecoomb Campus, 1.9 miles south-east of Patcham, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
