Washroom sealing in Northdown, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. Site teams most often ask us about urinal joints that look unhygienic and complaints from staff, guests or users about tired washrooms, across accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs. A specialist sealant contractor works differently from a general builder: on jobs in Northdown, preparation and product choice get the time they need.
A place of Northdown’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we’re called out for in Northdown
Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.
Look out for the following:
- Mould spotting along silicone joints
- Resealing that didn’t last because the old bead stayed
- Panel joints letting water behind
- Gaps where vanity tops meet the wall
In a centre such as College Square Shopping Centre, 1.6 miles to the west of Northdown, public washrooms are resealed a block of facilities at a time.

Questions about Northdown
Do hotels near Northdown have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is Northdown too small for you to travel to?
No. Places such as Northdown are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What guarantee comes with washroom resealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Can you clean the mould off instead of resealing?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
Is it OK to put new silicone on top of the old?
The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.
Toilets, showers and kitchens around Northdown
Northdown lies within about 1 mile of the sea, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. Seven care or nursing homes sit less than 2 miles from Northdown. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home.
Healthcare estates like Queen Elizabeth The Queen Mother Hospital, 1.5 miles to the south-west of Northdown, expect contractors to follow their permits and cleaning rules in every washroom. Office toilets at parks like Copper Leaf Business Park (1 mile south of Northdown) take steady weekday use, and mouldy silicone soon shows.

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Water escaping beneath the floor rather than through a joint
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Loose panels, vanity units or tiles, which need fixing first
If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Why deal with it now?
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Inspect washroom sealant regularly
- Mention any site permits or estates rules at quote stage
- Note failing joints building by building
- Clean sealant with gentle products and a soft cloth
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.
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.
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. If neighbouring businesses or buildings around Northdown need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Preparing the site
- Move anything stored against the joints
- Tell us what induction or permit system the site runs
- Send your site hours and access windows
