Construction mastic for Betchworth sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Betchworth need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- Drawings, the sealant specification and your programme come to us for pricing.
- 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.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements

Construction mastic in Betchworth, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. We work on window and door perimeters, sanitary and kitchen joints and floor and skirting junctions, and the usual reasons a site gets in touch are old sealant on a refurbishment that needs stripping before new work and frame gaps too wide for sealant alone. A single leaking joint is often how a building in Betchworth first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites around smaller places like Betchworth can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

Common problems we fix in Betchworth
On construction sites, joints usually fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Any of the following is a good reason to get the joints checked over:
- A long mastic snag list close to completion
- Frame perimeters left unsealed or poorly sealed
- Sanitary sealant damaged by following trades
- Frame gaps too wide for sealant alone
For contractors refurbishing units at places like Chesterfield Business Park, 1.5 miles to the east of Betchworth, the mastic covers cladding panels, roller-door and window perimeters.
Questions to ask before you book
- What the guarantee covers, and for how long
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Frame gaps too wide for sealant, which the installer needs to correct
- Joint design decisions that belong to the architect or engineer
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal

FAQs: Betchworth
Do you take on work at healthcare sites like Dorking Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Betchworth off your patch?
Not at all. Betchworth is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Can the building stay open while you work?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Surface by surface
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.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Sites and facades in and around Betchworth
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Betchworth lies roughly 19 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Further education sites such as Reigate College (to the east of Betchworth) are extended and refurbished from time to time, with mastic often programmed into the summer break. School extensions, at buildings such as North Downs Primary School, normally run to the summer holidays, mastic included.

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Share drawings and the specification as soon as possible
- Check frame gaps are within the sealant’s range before sealing
- Use the product the specification names
- Keep finished joints away from paint, plaster and scrapers
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
