Washroom sealing for commercial buildings in Old Chiswick
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we will confirm with the quote. If you have open joints along basins and vanity units and kitchen worktop joints that can’t be kept clean, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Old Chiswick is the same: the right product in a properly prepared joint.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Your questions answered
Will our hotel in Old Chiswick need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Would you work within a site like Charing Cross Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you do washroom sealing in healthcare settings?
Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote before we start.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How soon can a washroom be used after resealing?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How the job changes by surface
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Old Chiswick starts with access. Give us the hours we can be on site and we will schedule to suit.
- We survey each room, count the joints and note anything behind them that needs another 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.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs

Doing it in-house
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, which is what makes a joint last.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
