About commercial sealant contractors in SP10
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. We work on external facade joints, floor and threshold joints and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are gaps behind commercial kitchen worktops and sinks and a top-up bead over failed sealant, now lifting.
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
How we quote

Commercial premises across SP10
Shop fits, office refurbishments and hotel refits in towns such as Andover, Picket Twenty and Finkley Down all leave joints that need sealing. Visible joints call for a matched colour and a clean tooled finish.
London and the South East are among the drier parts of the UK, though outside work in SP10 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
Andover: In hotels such as The Globe Hotel, which lies south-east of Andover, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. If you have premises on more than one site, say at Northern Avenue Retail Park and Churchill Retail Park, one contractor and one quote can cover both.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What we are called out for in SP10
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into so it soon peels and traps moisture against the joint. Getting back to a clean joint then means removing every layer.
Most enquiries start with one or more of the following:
- Damp patches where an external joint has failed
- Window and door perimeter joints that have cracked open
- Black mould through washroom sealant that won’t clean off
- Layers of sealant, all of them failing
Keeping the joints sound
After handover, a little attention goes a long way:
- Make sure ventilation in wet areas is switched on and working
- Log reseals in the O&M or maintenance records
- Keep barriers up until the new sealant has cured
- Check sealant as part of routine building inspections
New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Keeping signs or barriers up until then protects the finish.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to.
Why deal with it now?
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after. Where it helps, we quote a patch and a full reseal side by side.
What your quote should include
- Can the work be phased to keep areas open?
- Their public liability cover
- Who will actually carry out the work
- What site paperwork they can supply
Different surfaces, different methods
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.
Your questions answered
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
Can you supply RAMS and insurance details?
Send your site requirements with the enquiry, and the paperwork is confirmed with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
Do you work for facilities managers and managing agents?
Yes. FMs, managing agents and landlords are among our regular clients. We can work to your instruction process and site rules.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Will you just go over the old 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.
Do you work in SP10?
Yes. We cover SP10, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.
