Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Darby Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.

Commercial sealant contractors in Darby Green, done properly
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. If you have wall and floor joints that have lost their seal and frame sealant that has cracked, shrunk or pulled away, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Darby Green, that means joint design, primers and backing rod as standard.
A lot of what we do in Darby Green is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
Rural business units near smaller places such as Darby Green are frequently converted agricultural buildings. 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions we are asked in Darby Green
Is a smaller place like Darby Green outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Will our hotel in Darby Green need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Which site documents can you send us?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
Does commercial sealant work come with a guarantee?
A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.
Could the old sealant in an older building contain asbestos?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Sealant on show in Darby Green’s commercial buildings
At about 33 miles from central London, Darby Green is within reach of the capital. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. A 2-mile radius around Darby Green takes in 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, and the work can be phased so the rest of the hotel keeps trading.
On a business park such as The Meadows Business Park, 1.2 miles east of Darby Green, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Make sure ventilation in wet areas is switched on and working
- Ask fit-out and M&E contractors to report any sealant they disturb
- Don’t let cleaning or traffic back on before the cure time is up
- Brief cleaning contractors to avoid scourers and blades on sealant
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
Commercial clients in Darby Green
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Leave it or put it right?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. Older rural buildings around Darby Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Walls or slabs moving more than any sealant can take
- Faulty windows rather than failed perimeter sealant
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Movement joints in walls and floors
- Floor and threshold joints
- Washrooms and tea points
- External facade joints
- Window and door perimeters
- Kitchen worktops and splashbacks
Different surfaces, different methods
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
Washrooms and toilets
Mould that has grown into washroom sealant can’t normally be cleaned out. The lasting answer is removal, preparation and a new sanitary bead.
