Signs you need washroom sealing in Dunn Street
Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.
Look out for the following:
- Complaints from staff, guests or users about tired washrooms
- Black mould inside silicone joints that cleaning can’t shift
- Resealing that didn’t last because the old bead stayed
- Stained sealant around pans and urinals
Healthcare estates like Spire Alexandra Hospital, 1.9 miles to the west of Dunn Street, expect contractors to follow their permits and cleaning rules in every washroom.
What your quote should include
- How the existing material will be dealt with
- Their plan for phasing and protecting the area
- How they handle RAMS and site documents
- Which product they’ll use, and why it suits the joint

Cost factors for washrooms and wet areas
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
- The total length or number of joints
- Backing rod, priming and other preparation
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.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
- The asbestos register, for older buildings
- What the building is and how it’s used
For a fixed quote, give us a call on 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.
How the job changes by surface
Healthcare and care settings
In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed and any permits the site uses.
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.

Keeping the joints sound
A few simple habits keep the new joints working:
- Mention any site permits or estates rules at quote stage
- Report split joints at trays and basins early
- Don’t leave trays and floors sitting wet
- Add sealant joints to planned maintenance checks
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For work around Dunn Street, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- Joints are cleaned, degreased and dried before sealing.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Move anything stored against the joints
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work

Advice
Questions we’re asked in Dunn Street
Is Dunn Street too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like Spire Alexandra Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you need to remove the old sealant?
We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can washrooms stay open while you work?
Only the area we are working in is closed. Rooms go back into use once the sealant has cured and we start the next.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
