Washroom sealing in Streatham
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. If you’re dealing with failed sealant in a tea point or staff kitchen and sealant stained black around basins and showers, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Streatham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In Streatham, 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.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Signs you need washroom sealing in Streatham
Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
These are often picked up first by site or facilities staff:
- Failed sealant behind washroom basins
- Split or peeling sealant at shower trays
- Mould spotting along silicone joints
- Urinal joints that look unhygienic
For a college such as South Thames College Tooting Centre, 1.7 miles to the west of Streatham, half-term and summer give the windows for washroom work.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Can the work be phased to keep areas open?
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Share your site rules when you send details
- Keep a record of which washrooms need attention
- Don’t leave trays and floors sitting wet
- Act on the first split you see at a shower tray
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.
Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.
Surface by surface
Urinals and WC pans
Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and look unhygienic.
Kitchens and tea points
We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.
Common questions from Streatham clients
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can work in a care setting near Streatham go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can the sealant be colour-matched?
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.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How much does the work cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.

Related advice
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
