Common questions from Kenton clients
Do hotels near Kenton have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Would you work within a site like Northwick Park Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
When can showers be used after new sealant?
That varies with the sealant and the room temperature. You’ll get a reopening time for each area before we leave it.
Washroom sealing in Kenton, done properly
Whether it’s a single toilet block in Kenton or a programme across several buildings, we work the same way: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on urinals and WCs, showers, trays and wet room floors and vanity units and basins, and the failures we’re asked to look at most are open joints along basins and vanity units and kitchen worktop joints that can’t be kept clean. One point of contact handles commercial sealant work in Kenton from the first photos to the final walk-round, whether it’s one building or several.
Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
Problems stay small when the joints are checked regularly. In particular:
- Clear standing water from shower floors where possible
- Keep a record of which washrooms need attention
- Report split joints at trays and basins early
- Avoid scourers and harsh descalers on silicone
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
Do you need washroom sealing in Kenton?
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.
What tends to prompt an enquiry:
- Panel joints letting water behind
- Shower tray joints that have opened up
- Kitchen worktop joints that can’t be kept clean
- Resealing that didn’t last because the old bead stayed
Halls of residence and teaching buildings at universities such as Westminster University (to the south-west of Kenton) are easiest to reseal during vacations.
What your quote should include
- How they’ll work around occupants
- Which product they’ll use, and why it suits the joint
- Their public liability cover
- How the joint faces will be prepared and primed
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Keeping Kenton washrooms open while we work
The 2 miles around Kenton include two care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs. A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance.
Office washrooms on sites such as East Lane Business Park, 1.4 miles to the south of Kenton, are in use all working day, so resealing is phased to keep some open. Customer toilets in retail centres such as St. George's Shopping Centre, 1.4 miles west of Kenton, rarely close, so resealing is phased.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a few hours for one toilet block, with bigger buildings phased across a number of visits. Planning a London job such as one in Kenton starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Before we start on site
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
