Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Construction mastic in East Hill, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. If you’re dealing with different trades sealing to different standards and window and door perimeters that won’t pass inspection, we can help. Facilities teams, main contractors and managing agents in East Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as East Hill is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Quoting for work in East Hill
There’s no standard rate for sealant work, because every site is different. What we take into account:
- The size and state of each joint
- The product specified
- Phasing around occupants
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Your programme or deadline
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or email drawings and photos with what you know.
Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Sites and facades in and around East Hill
East Hill is about 18 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. East Hill is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
When units on a site such as West Kingsdown Industrial Estate (1.1 miles east of East Hill) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hospital estates such as Sevenoaks Hospital, 4 miles to the south-west of East Hill, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
East Hill is about 5 miles north-east of Sevenoaks, in Kent. Commercial clients in East Hill use us for work on mastic packages, as part of our coverage of Kent. Across Kent, 931 places are covered, East Hill among them. We also cover London, around 18 miles from East Hill.

Common questions from East Hill clients
Can you take on a job at a hospital such as Sevenoaks Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is East Hill too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we will plan applicators around it, sealing as areas become ready.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.
Why deal with it now?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. Converted and older buildings near places like East Hill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Different surfaces, different methods
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Common problems we fix in East Hill
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
It’s worth sending us details if you spot any of the following:
- Early adhesion failures on new external joints
- Cracks opening in caulked internal joints
- Old sealant on a refurbishment that needs stripping before new work
- Inconsistent sealant finishes from plot to plot
Historic houses such as Lullingstone Castle (to the north-west of East Hill) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
