Washroom sealing for Greenhithe sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Surface by surface
Changing rooms and gyms
Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.
Showers and trays
Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.
Washroom sealing in Greenhithe
From one staff toilet in Greenhithe to washrooms across a whole estate, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. We work on vanity units and basins, accessible toilets and changing rooms and showers, trays and wet room floors, and what we are called in for most is split or peeling sealant at shower trays and open joints at the base of cubicle panels. Whoever orders the work in Greenhithe, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Jobs in a smaller place such as Greenhithe are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. A list and photos let us quote and plan so it’s done in one visit where possible.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

FAQs: Greenhithe
Is Greenhithe too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you take on a job at a hospital such as Darent Valley Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is it OK to put new silicone on top of the old?
The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Commercial washrooms in Greenhithe
A number of hotels sit less than 2 miles from Greenhithe. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available. At about 17 miles from central London, Greenhithe is within reach of the capital, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.
For a store at a site such as Bluewater Shopping Centre, 0.8 miles to the south-west of Greenhithe, the staff room and customer toilets can be resealed in quiet periods. At a hospital like Darent Valley Hospital (1.5 miles south-west of Greenhithe), patient and staff washrooms are best done in short phases agreed with the ward. For a campus such as University of Greenwich (0.9 miles south-west of Greenhithe), showers in residences and washrooms in teaching blocks can be programmed around term dates.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Brief cleaning staff to treat joints gently
- Photograph and log failed joints across the estate
- Don’t leave trays and floors sitting wet
- Share your site rules when you send details
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life over time.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Several jobs near Greenhithe can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Let us know about inductions and permits
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Water from plumbing, not from a joint
- Water escaping beneath the floor rather than through a joint
- Mould caused by poor ventilation, which will return until the extract is fixed
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Vanity units and basins
- Showers, trays and wet room floors
- Urinals and WCs
- Kitchens and tea points
What happens if it’s left?
Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Small buildings around Greenhithe suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
