About our washroom sealing in Tyttenhanger
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Site teams most often ask us about complaints from staff, guests or users about tired washrooms and black mould inside silicone joints that cleaning can’t shift, across accessible toilets and changing rooms, showers, trays and wet room floors and vanity units and basins. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tyttenhanger is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Community buildings around smaller places like Tyttenhanger have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
A 12-month guarantee applies to all our work in Hertfordshire. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Condensation from failed extract fans
- Vanity carcasses that have swollen
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.

Cost factors for washrooms and wet areas
A fixed quote reflects the actual work. It allows for:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- The postcode of the building
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Questions we are asked in Tyttenhanger
Can you work around term dates at a campus such as University of Hertfordshire?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will our hotel in Tyttenhanger need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
Is old silicone taken out first?
The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Respect the cure time before reopening each room
- Brief cleaning staff to treat joints gently
- Note failing joints building by building
- Squeegee showers and trays after busy periods
Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
