Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Leave it or put it right?
Putting off a reseal normally moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next, which brings decorators and flooring contractors into the repair. Resealing while only the sealant has failed keeps the job small. One visit to deal with every failing joint makes more sense than several trips to a place like Hook Green. Photos of every joint help us quote for the whole job.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Commercial sealant contractors in Hook Green, done properly
How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. We work on floor and threshold joints, kitchen worktops and splashbacks and movement joints in walls and floors, and the usual reasons a site gets in touch are damp patches where an external joint has failed and smeared sealant across finishes from a rushed job. Looking for mastic applicators who cover Hook Green? We have been sealing commercial buildings since 2005.
On a typical commercial building in Hook Green, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Rural business units near smaller places such as Hook Green are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.
Our workmanship is guaranteed for 12 months, in Hook Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Advice
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Put external and wet-area joints on a regular inspection round
- Act on the first lifting edges rather than waiting
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Don’t let cleaning or traffic back on before the cure time is up
Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just call the office on 01277 525 020 or send photos by email for a quote.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to.
How the job changes by surface
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach. We seal to a neat, cleanable finish and work around service times you agree with us.

Sealant on show in Hook Green’s commercial buildings
Hook Green is about 19 miles from central London. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. The area within 2 miles of Hook Green holds a number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.
Premises within reach of Longfield station (to the south-west of Hook Green) often have busy frontages where joints are seen by everyone passing. If you have premises on more than one site, say at Fawkham Business Park and Ebbsfleet Business Park, one contractor and one quote can cover both. In a retail centre such as Bluewater Shopping Centre, 2.7 miles to the north-west of Hook Green, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Water from a services leak rather than a joint
- Old mastic that tests positive for asbestos
- Walls or slabs moving more than any sealant can take
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
What we seal
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Window and door perimeters
- External facade joints
- Washrooms and tea points
Site staff or a sealant specialist?
Certain joints really need a specialist: for instance 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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
