How we handle commercial sealant contractors in South Street
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. We work on washrooms and tea points, external facade joints and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are movement joints packed with grit and debris and gaps behind commercial kitchen worktops and sinks. Most enquiries from South Street start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Occupied buildings in South Street need the work phased: washrooms in turn, floors in sections and entrances kept open.
Business units in the countryside around places like South Street are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Working on commercial sites near South Street
Less than 3 miles from South Street there are two named estates and business parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. At about 22 miles from central London, South Street is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.
Shops and cafés around stations like Meopham station, 2.4 miles to the north of South Street, trade from early, so work is timed around them. On estates like Bowes Industrial Centre, which lies north of South Street, the office and welfare end of each unit has its own sealant to maintain.
South Street is about 6 miles south of Gravesend, in Kent. We cover commercial sites throughout South Street, for single jobs and planned programmes alike. South Street is one of 931 places in Kent on our list. For work in that direction, see our London page (22 miles or so).

Local landmarks in South Street
In South Street, that means premises near Trosley Country Park and Meopham School and the streets around them. The nearest railway station is Meopham station, roughly 2.4 miles north of the centre.

Signs you need commercial sealant contractors in South Street
A split down the middle of the bead tells a different story. Typically the movement was too much for the sealant chosen because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.
Common reasons buildings call us in:
- External beads that have gone brittle and cracked
- Greasy, split joints in a kitchen or tea point
- Damp patches where an external joint has failed
- Sanitary sealant that has gone black and patchy
A business with units at Bowes Industrial Centre and Heaver Farm Trading Estate needn’t use two contractors for its sealant.

FAQs: South Street
Can the sealant on our South Street premises match the finishes?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Will you take on work at estates like Bowes Industrial Centre, close to South Street?
Yes. We cover South Street and the area around it, including industrial estates, business parks and retail parks such as Bowes Industrial Centre. A few photographs and the unit address let us price the work.
Is failed sealant stripped out, or sealed over?
Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How the job changes by surface
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.
Shop fronts and retail fit-outs
In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal. We will confirm the colours available for the specified product.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Structural cracks or movement the joints weren’t designed for
- Faulty windows rather than failed perimeter sealant
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Washrooms and tea points
- Floor and threshold joints
- External facade joints
- Window and door perimeters
What happens if it’s left?
Some managers wait for a fit-out before touching the mastic. 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. Converted and older buildings near places like South Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
