How we handle washroom sealing in Bankside
From one staff toilet in Bankside to washrooms across a whole estate, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. If you have stained sealant around pans and urinals and black mould inside silicone joints that cleaning can’t shift, we can put it right. Facilities teams, main contractors and managing agents in Bankside tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to call us in Bankside
Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.
Common reasons buildings call us in:
- Failed sealant in a tea point or staff kitchen
- Sealant stained black around basins and showers
- Gaps where vanity tops meet the wall
- Panel joints letting water behind
For centre management at a site such as Brunswick Centre, 1.5 miles to the north-west of Bankside, washroom work is planned around footfall.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
Surface by surface
Showers and trays
If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.
From enquiry to sign-off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. In Bankside, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
What we need from you
- For older buildings, check the asbestos register before work
- Agree which areas must stay open
- Flag any permit to work we will need

Advice
Leave it or put it right?
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Bankside: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Can you take on a job at a hospital such as London Bridge Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you phase washroom resealing?
We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
Busy facilities in and around Bankside
There are two care or nursing homes within about 2 miles of Bankside. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home. The area within 2 miles of Bankside holds plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.
At a university such as University of Notre Dame (London Global Gateway), which lies west of Bankside, summer is the usual window for resealing residence bathrooms. For a site such as London Bridge Hospital, 0.6 miles east of Bankside, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Should maintenance staff do it?
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 will confirm the paperwork you need with the quote.
