How we handle mastic sealing in Boyden Gate
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. If you have damp patches beside frames and window mastic that has split and shrunk, we can help. A specialist sealant contractor works differently from a general builder: in Boyden Gate, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Boyden Gate, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Whoever the client is, the cover is the same: 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.

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. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Blocks and managed buildings in Boyden Gate
The sea is no more than about 3 miles from Boyden Gate. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
If you look after a block within reach of Herne Bay station, 3.4 miles west of Boyden Gate, frame and balcony mastic can be renewed on one programme. Site managers at schools like Chislet Church of England Primary School can fit frame mastic into the summer works. Trustees of buildings like Church of St Mary the Virgin can bring frame and external mastic into a planned maintenance list.

Commercial clients in Boyden Gate
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
How the job changes by surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
What happens if it’s left?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Older rural buildings around Boyden Gate move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Why us?
- Our applicators hold CSCS cards
- RAL and finish matching where the product range allows
- A Constructionline member, so easy to vet
- Specification-led, product-correct work

Keeping the joints sound
Once the work is signed off, these steps help:
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
- Share the asbestos register when you send details
- Protect low-level joints in entrances
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a day or two for a single block, longer for an estate programme. If others near Boyden Gate need work, visits can be combined. A fixed quote is given before anything starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Confirm the product named in the specification
- Share the asbestos register for older buildings
- Flag any permit to work we’ll need

FAQs: Boyden Gate
Do you cover business parks and estates near Boyden Gate, such as Chislet Business Park?
Yes. Estates, retail parks and business parks around Boyden Gate, Chislet Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is a smaller place like Boyden Gate outside your area?
No. Places such as Boyden Gate are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
