How we handle washroom sealing in Poynders End
Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Most enquiries involve black mould inside silicone joints that cleaning can’t shift and kitchen worktop joints that can’t be kept clean, on kitchens and tea points, accessible toilets and changing rooms and urinals and WCs. Looking for mastic applicators who cover Poynders End? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Fittings that move too much to hold a bead
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Condensation from failed extract fans

Common problems we fix in Poynders End
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.
It’s worth sending us details if you spot any of the following:
- Stained or open joints at kitchen sinks and worktops
- Discoloured joints around urinals and WC pans
- Split or peeling sealant at shower trays
- Washrooms that look worn because of the sealant
Where you are responsible for a hall attached to a building such as Church of St Martin, its kitchen and toilets need sealant that stays cleanable.
What your quote should include
- Proof of insurance
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- How they’ll work around occupants
What sets the cost
The price varies from site to site. Expect it to depend on:
- Whether the work must be split into stages
- Travel to remote or island sites
- How accessible the joints are
- Joint width, depth and condition
A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- What the building is and how it’s used
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call 01277 525 020 or use the quote form.
Keeping the joints sound
A few simple habits keep the new joints working:
- Keep a record of which washrooms need attention
- Respect the cure time before reopening each room
- Inspect washroom sealant regularly
- Don’t leave an open joint at a basin or tray
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
Questions about Poynders End
Will you plan work around the academic year at somewhere like North Hertfordshire College?
Yes. Education sites normally 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 hospital work, at somewhere like Lister Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Is old silicone taken out first?
The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.
Do you phase washroom resealing?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
