Facade sealing in Chevening
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you are dealing with staining on stone next to old sealant and facade joints cracked through the middle, we can help, whatever the surface. Searching for sealant specialists in Chevening? We’ve been sealing commercial buildings since 2005.
Sites around smaller places like Chevening can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.
A 12-month guarantee applies to all our work in Kent. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Add perimeter sealant to planned maintenance checks
- Check that rainwater leaves the facade the way it was designed to
- Share access with other external trades
- Ask about asbestos in pre-2000 mastic
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.

What we are called out for in Chevening
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.
Any of the following is a good reason to get the joints checked over:
- Perimeter sealant that has split or peeled away
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
- Water coming in around window frames
School extensions, at buildings such as Combe Bank School, normally run to the summer holidays, mastic included.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Their public liability cover
- Health and safety accreditation such as CHAS
- Will CSCS-carded applicators be on site?
Common questions from Chevening clients
Can you work at a site such as North Downs Business Park, by Chevening?
Yes. Our area takes in Chevening and its surroundings, with estates and business parks such as North Downs Business Park included. Photos and a short description are enough for a first look.
Is a hospital such as Sevenoaks Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Which sealant do you use on facades?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call 01277 525 020 or use the quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Facade sealing around Chevening: how the place shapes the job
Central London is about 17 miles from Chevening. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. 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 the external programme keeps a little slack.
Hotel extensions and refits, at places such as Donnington Manor Hotel (1.2 miles east of Chevening), typically run between busy periods, so the sealing is squeezed into short windows. For contractors refurbishing units at places like North Downs Business Park, 1.2 miles to the north-east of Chevening, the mastic covers cladding panels, roller-door and window perimeters.

How the job changes by surface
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.
Quoting for work in Chevening
Each job is priced on its own details. The main factors are:
- Site requirements such as inductions and permits
- How accessible the joints are
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Where the site is, with the postcode
- Specification clauses that apply
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or send details through our quote form.
