What the job involves on each 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.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.
Sealant applicators in Sittingbourne
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you’re dealing with expansion joints with the sealant torn out and black mould through washroom sealant that won’t clean off, we can put it right, on floor and threshold joints, washrooms and tea points and external facade joints alike. Most enquiries from Sittingbourne start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The most common commercial job in Sittingbourne is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Smaller commercial landlords and businesses in a town like Sittingbourne often have a handful of sealant jobs that can go on one visit: a frontage, a staff washroom, a kitchen and a few window perimeters, for example. One fixed quote then covers the lot.
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.

What Sittingbourne’s businesses ask us to seal
Sittingbourne lies within about 2 miles of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. A matched colour is only half the brief on an exposed frontage. The 3 miles around Sittingbourne take in two named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.
Occupiers with premises at both Kent Science Park and Newington Enterprise Centre could have the sealant at each handled under one quote. Shops and cafés around stations like Sittingbourne station, under half a mile south of Sittingbourne, trade from early, so work is timed around them.

Your questions answered
Is Kent Science Park, near Sittingbourne, within your area?
Yes. Estates, retail parks and business parks around Sittingbourne, Kent Science Park among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Must a hotel around Sittingbourne close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Do you work for facilities managers and managing agents?
Yes. You can send details through our quote form.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check sealant as part of routine building inspections
- Don’t let cleaning or traffic back on before the cure time is up
- Check joints after other trades have worked nearby
Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can call the office on 01277 525 020 or email the details over and send a picture.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

Advice
Do you need commercial sealant contractors in Sittingbourne?
A split down the middle of the bead tells a different story. That typically means the joint stretched further than the product could cope with. The same product in the same joint tends to fail the same way.
Common reasons buildings call us in:
- Weathered facade sealant that no longer flexes
- Frame mastic that has hardened and come away from the wall
- Smeared sealant across finishes from a rushed job
- Wall and floor joints that have lost their seal
Offices at parks like Kent Science Park (to the south of Sittingbourne) have receptions, kitchens and glazed partitions where a tidy joint matters.

Leave it or put it right?
It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. In a town like Sittingbourne, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
