Construction mastic for Fernhill sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
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 easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How we handle construction mastic in Fernhill
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. Site teams most often ask us about frame gaps too wide for sealant alone and external joints sealed in damp or cold conditions that are now failing, across floor and skirting junctions, cladding and panel joints and internal decorators’ caulk. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Fernhill, that means joint design, primers and backing rod as standard.
Conversions of older rural buildings near smaller places such as Fernhill bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Fernhill, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.

Fernhill: questions and answers
Can you work on a hospital site such as Spire Gatwick Park Hospital (Private)?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Fernhill outside your area?
No. Places such as Fernhill are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we will tell you.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Owners, agents and contractors
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Why it’s worth doing now in Fernhill
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Halls, stores and units around places like Fernhill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Contractors’ notes for Fernhill
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 we time external mastic for dry faces and agree it with the site team. Central London is about 24 miles from Fernhill. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
For a contractor at a hotel such as Marriott Courtyard Hotel (0.6 miles west of Fernhill), the mastic often has to be finished before a reopening date. For contractors at a school such as Oakwood School, sealing has to be finished before term starts. Recladding or extending a unit at a site like Maple Business Park, less than half a mile to the east of Fernhill, brings panel joints and frame perimeters into the programme.
