Sealant applicators in Kew
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. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on floor and threshold joints, window and door perimeters and washrooms and tea points, and what we are called in for most is leaks that seem to come through a sealant line and frame sealant that has cracked, shrunk or pulled away. A specialist sealant contractor works differently from a general builder: on jobs in Kew, preparation and product choice get the time they need.
Quotes for commercial sealant in Kew can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.
In London, most commercial sealant work happens in buildings that stay open: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How the job changes by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.
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, matched to the frame colour where colour matters.
Looking after the joints
For the best life from the joints:
- Have extract fans checked so wet areas dry out
- Put external and wet-area joints on a regular inspection round
- Keep a record of which joints were resealed and when
- Ask fit-out and M&E contractors to report any sealant they disturb
New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.
Tenants and staff spot black or split sealant quickly. Planned replacement saves fielding the same complaint again and again.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Structural cracks or movement the joints weren’t designed for
- Broken glass or blown double-glazed units
- Old mastic that tests positive for asbestos
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.
Where we work in Kew
- Washrooms and tea points
- Movement joints in walls and floors
- Floor and threshold joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- External facade joints
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common problems we fix in Kew
When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
What tends to prompt an enquiry:
- Damp patches where an external joint has failed
- Mouldy silicone around WCs, urinals and vanity tops
- Earlier reseals applied straight onto the failed bead
- Weathered facade sealant that no longer flexes
For premises near Chiswick station, 0.5 miles south-east of Kew, footfall is part of the plan: work is phased so shops and offices keep trading.
What your quote should include
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- What level of public liability insurance do they hold?
- How the joint faces will be prepared and primed
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Planning a London job such as one in Kew starts with access. Send the building rules and access times with your enquiry.
- First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000

Related advice
Your questions answered
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Does a hotel in Kew need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What about asbestos in old mastic?
It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested.
How do you keep disruption to occupiers down?
It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing, until its cure time has passed.
Do you work in Kew?
Yes. Kew falls within our area, and the simplest way to start is to ring 01277 525 020 or email us.
Working on commercial sites near Kew
Kew has a good number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes. Less than 3 miles from Kew there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.
Kew is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. If you have premises on more than one site, say at Kew Retail Park and Phoenix Trading Estate, one contractor and one quote can cover both.
