Construction mastic in Charlwood, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. We work on sanitary and kitchen joints, floor and skirting junctions and internal decorators’ caulk, and the usual reasons a site gets in touch are inconsistent sealant finishes from plot to plot and old sealant on a refurbishment that needs stripping before new work. Looking for mastic applicators who cover Charlwood? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Conversions of older rural buildings near smaller places such as Charlwood bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

After the work
To get the most from the new sealant:
- Keep scrapers and abrasive pads off new beads
- Put any product change through the designer first
- Note which sealant went where at handover
- Keep finished joints away from paint, plaster and scrapers
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. If that happens, let us know.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone.
What we’re called out for in Charlwood
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Look out for the following:
- A mastic package split between trades with no clear owner
- Frame gaps too wide for sealant alone
- Internal caulk splitting as the building dries out
- Old sealant on a refurbishment that needs stripping before new work
Extensions at sites like Farmfield Hospital (psychiatric) (1.3 miles north-east of Charlwood) usually sit beside working departments, and the mastic follows strict access rules.

New build and refits around Charlwood
Charlwood is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. A number of hotels sit less than 2 miles from Charlwood. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Hotel extensions and refits, at places such as Stanhill Court Hotel (1 mile north-west of Charlwood), normally run between busy periods, so the sealing is squeezed into short windows. Recladding or extending a unit at a site like Gatwick Business Park (to the north-east of Charlwood) brings panel joints and frame perimeters into the programme.

Common questions from Charlwood clients
Is Charlwood too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is a hospital such as Farmfield Hospital (psychiatric) somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
What happens if the weather stops external sealing?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes whatever the programme allows, since the work follows the trades as areas are released.
