Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
About our construction mastic in Sevenoaks
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas. That keeps the work right first time and saves rework. Most enquiries involve sanitary sealant damaged by following trades and new external sealant already peeling away, on brick and block movement joints, window and door perimeters and cladding and panel joints. Looking for mastic applicators who cover Sevenoaks? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Older town-centre buildings in places like Sevenoaks are often converted to new uses or extended, so new windows and cladding meet old masonry. Those junctions need a sealant and primer that suit both surfaces.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.
Your questions answered
Can you work on a hospital site such as Sevenoaks Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can the mastic package for our job in Sevenoaks follow the site programme?
Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Joint design decisions that belong to the architect or engineer
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.
Where we work in Sevenoaks

Why it’s worth doing now in Sevenoaks
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. In a town such as Sevenoaks, a lot of buildings are older and have been altered over time, and joints where old meets new tend to fail first. Resealing them early protects the building behind.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
