About our washroom sealing in Gilbert Street
Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. Most enquiries involve split or peeling sealant at shower trays and failed sealant in a tea point or staff kitchen, across urinals and WCs, vanity units and basins and IPS panels and cubicles.

Your questions answered
Must every washroom in our Gilbert Street building shut while you work?
Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Is Gilbert Street too small for you to travel to?
Not at all. Gilbert Street is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can washrooms stay open while you work?
Just the room being resealed is out of use. Each room reopens after the sealant’s cure time, then we move on.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you reseal washrooms in healthcare buildings?
Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When to call us in Gilbert Street
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.
Look out for the following:
- Urinal joints that look unhygienic
- Sealant laid over old silicone and now peeling
- Stained or open joints at kitchen sinks and worktops
- Washrooms that look worn because of the sealant
For a school such as Ropley Church of England Primary School, washroom and kitchen sealant can be renewed around term dates.
What your quote should include
- How the joint faces will be prepared and primed
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
How the quote is worked out
To price the job, we consider:
- Working within restricted access windows
- How accessible the joints are
- Joint width, depth and condition
- Whether old sealant has to be cut out first
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 you’ll have a fixed figure to work with.
