Washroom sealing for commercial buildings in Lissenden Gardens
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. We work on urinals and WCs, accessible toilets and changing rooms and kitchens and tea points, and the usual reasons a site gets in touch are failed joints along IPS and cubicle panels and urinal joints that look unhygienic. One point of contact handles commercial sealant work in Lissenden Gardens from the first photos to the final walk-round, whether it’s one building or several.
In Lissenden Gardens, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Commercial washrooms in Lissenden Gardens
Six care or nursing homes sit less than 2 miles from Lissenden Gardens. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible. Lissenden Gardens has a good number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.

How the quote is worked out
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- How much there is to seal
- Location, for remote and island sites
- The size and state of each joint
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- The site address and postcode
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email a schedule or drawings with what you know.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Lissenden Gardens, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- 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.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
Preparing the site
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
- For older buildings, check the asbestos register before work

General trades versus a specialist
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.
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.
Surface by surface
Urinals and WC pans
Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.
Basins and vanity tops
Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Common problems we fix in Lissenden Gardens
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and say if it needs a plumber or another trade.
What tends to prompt an enquiry:
- Complaints from staff, guests or users about tired washrooms
- Black mould inside silicone joints that cleaning can’t shift
- Failed sealant behind washroom basins
- Sealant lifting along a tray edge
Halls of residence and teaching buildings at universities such as American University in London, 1.5 miles east of Lissenden Gardens, are easiest to reseal during vacations.
