Washroom sealing in Stonymarsh, done properly
In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on urinals and WCs, IPS panels and cubicles and accessible toilets and changing rooms, and the usual reasons a site gets in touch are gaps where vanity tops meet the wall and washrooms that look worn because of the sealant. Searching for sealant specialists in Stonymarsh? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In and around smaller places like Stonymarsh, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

What the job involves on each surface
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors so the edges are checked carefully.
Showers and trays
In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.
Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Mention any site permits or estates rules at quote stage
- Include joints in routine washroom inspections
- Don’t leave trays and floors sitting wet
- Keep extract fans working and vents clear
Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.
Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.
Why act early in Stonymarsh
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Around Stonymarsh, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Questions about Stonymarsh
Must every washroom in our Stonymarsh building shut while you work?
Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.
Is Stonymarsh too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Vanity carcasses that have swollen
- Water from plumbing, not from a joint
- Fittings that move too much to hold a bead
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly before you book.
