Facade sealing in Brasted
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and weathered facade joints that have lost their grip, across perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Brasted it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Brasted, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions about Brasted
Is a smaller place like Brasted outside your area?
No. Places such as Brasted are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you take on work at healthcare sites like Tandridge Priory?
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.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Why deal with it now?
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Around Brasted, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
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.

Building and refurbishing in Brasted
The area within 2 miles of Brasted holds several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Central London is about 18 miles from Brasted. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
When units on a site such as Salters Heath Business Centre, 2.4 miles to the east of Brasted, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Combe Bank School work to term dates, so mastic is programmed tightly. For a contractor working at a hospital such as Tandridge Priory (3.8 miles south-west of Brasted), perimeter and facade sealing is planned around patients and deliveries.
Brasted is about 3 miles west of Sevenoaks, in Kent. Businesses, contractors and managing agents in Brasted use us for work on facade joints, as part of our coverage of Kent. Across Kent, 931 places are covered, Brasted among them. Sites around London have their own page, about 18 miles away.

Near you in Brasted
We work on buildings around The White Hart pub. For rail, the closest station is Dunton Green station, roughly 3.1 miles north-east of the centre.

Doing it in-house
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
More services for Brasted
Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Maintenance after handover
After handover, these steps help:
- Keep pressure washers away from fresh sealant
- Plan facade sealing alongside redecoration
- Check that rainwater leaves the facade the way it was designed to
- Add perimeter sealant to planned maintenance checks
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly with a compatible product.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Brasted are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Move anything stored against the joints
- Arrange parking or a loading space
- Have the specification and drawings to hand

Advice
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Movement beyond what any sealant can handle
- Providing access systems for the work
- Damp caused by condensation inside the building
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
