How we handle construction mastic in West Hill
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve window and door perimeters that won’t pass inspection and snag items on joints that need redoing before handover, on brick and block movement joints, floor and skirting junctions and internal decorators’ caulk. Looking for mastic applicators who cover West Hill? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
For a contractor on a smaller site near West Hill, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Joint design decisions that belong to the architect or engineer
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Brick and block movement joints
- Floor and skirting junctions
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
What we are called out for in West Hill
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.
Most enquiries start with something like this:
- New external sealant already peeling away
- A long mastic snag list close to completion
- Cracks opening in caulked internal joints
- Oversized or tapered gaps around new frames
On a healthcare site such as The Montefiore Hospital, 0.5 miles west of West Hill, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Mastic packages on West Hill sites
With the shore within about 1 mile, West Hill counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Central London is about 46 miles from West Hill. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
Further education sites such as Waterbear College Brighton, less than half a mile to the south-east of West Hill, are extended and refurbished from time to time, with mastic often programmed into the summer break. Recladding or extending a unit at a site like Centenary Industrial Estate (to the north-east of West Hill) brings panel joints and frame perimeters into the programme.
West Hill is about 1 mile west of Brighton, in Brighton and Hove. We cover commercial sites throughout West Hill, for single jobs and planned programmes alike. Our Brighton and Hove coverage takes in 29 places, large and small.

Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. We will say so if a frame itself is the problem. Small buildings around West Hill suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why us?
- Colours confirmed for the specified product
- Over 20 years of commercial sealing
- Fixed quotes based on photographs, drawings or a visit

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask installers to correct oversized gaps first
- Brief following trades on areas that have been sealed
- Put any product change through the designer first
- Brief the final clean team to avoid blades near sealant
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and reduces snags.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in West Hill, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Before we start on site
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
- Make sure the joints can be reached
