Washroom sealing for commercial buildings in Stone
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. If you’re dealing with stained sealant around pans and urinals and shower tray joints that have opened up, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Stone tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Pub and restaurant kitchens around smaller places like Stone work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Questions about Stone
Will our hotel in Stone need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Can you work around term dates at a campus such as University of Greenwich?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.
Why deal with it now?
A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Small buildings around Stone suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a site in Stone, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- 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.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
When to call us in Stone
Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.
Look out for the following:
- Gaps where vanity tops meet the wall
- Complaints from staff, guests or users about tired washrooms
- Black mould inside silicone joints that cleaning can’t shift
- Split or peeling sealant at shower trays
For a site such as Darent Valley Hospital, 1 mile south-west of Stone, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.
Comparing quotes
- Do they follow the manufacturer’s priming guidance?
- The terms of the workmanship guarantee
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether old or failed sealant will be cut out, not overlaid
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
- Access and working height
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- A wide shot and a close-up of the area
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- The product your specification calls for
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
