Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Why deal with it now?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to. Damaged joints are removed and resealed from clean faces. Around Densole, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
What you get with us

Construction mastic in Densole, done properly
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you’re dealing with frame gaps too wide for sealant alone and existing joints on a refurb that need cutting out and resealing, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Densole, that means joint design, primers and backing rod as standard.
For a site near Densole, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Questions we’re asked in Densole
Is Densole off your patch?
No. Places such as Densole are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like Royal Victoria Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. We will flag if the detail needs a different product.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we have finished isn’t covered.
What joints do you seal on a new build?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
When to call us in Densole
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Things that typically lead to an enquiry:
- Sanitary sealant damaged by following trades
- Snag items on joints that need redoing before handover
- External joints sealed in damp or cold conditions that are now failing
- Failed sealant in an existing building being refurbished
Older buildings in the area around Densole, such as Acrise Place, 1.2 miles to the north-west of Densole, need care when sealed: the product has to suit soft or historic materials.

New build and refits around Densole
Densole sits in one of the drier corners of the country, the South East. 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. Central London is about 60 miles from Densole. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
On a campus such as University Centre Folkestone, which lies south of Densole, new teaching buildings and residences are usually built and refurbished around the academic year. On a healthcare site such as Royal Victoria Hospital, 3 miles to the south of Densole, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Densole is about 3 miles north of Folkestone, in Kent. Densole sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Kent, 931 places are covered, including Densole. London is covered too, some 60 miles away.
Anyone looking for construction mastic in CT18 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Near you in Densole
Densole’s nearest station is Folkestone West station, roughly 3.1 miles south. Well-known places in the area include Elham Valley Countryside Centre And Railway Museum (2.7 miles south-west) and Folkestone Castle (2.1 miles south). Open spaces near Densole include Cheriton Hill.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Work for main contractors and building owners
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, and our applicators hold CSCS cards.
CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
What affects the price in Densole
To price the job, we consider:
- Site requirements such as inductions and permits
- Joint width, depth and condition
- Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
