Commercial clients in Greenwich
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Greenwich can sit alongside others in a wider programme.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Washroom sealing for commercial buildings in Greenwich
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you are dealing with failed sealant in a tea point or staff kitchen and users noticing mouldy joints, we can help, whatever the surface. A single leaking joint is often how a building in Greenwich first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

How the job changes by surface
Kitchens and tea points
Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water escaping beneath the floor rather than through a joint
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.
Surfaces we seal
- Kitchens and tea points
- Urinals and WCs
- Vanity units and basins

Washroom sealing around Greenwich: points for this area
Greenwich has plenty of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. The 2 miles around Greenwich include four care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs.
In a centre such as Peninsular Retail Park (1.1 miles north-east of Greenwich), public washrooms are resealed a block of facilities at a time. Healthcare estates like Blackheath Hospital (1.2 miles south of Greenwich) expect contractors to follow their permits and cleaning rules in every washroom. Student showers at universities like University of Greenwich, under half a mile to the north-west of Greenwich, see more use than most, and their silicone shows it.
Greenwich is about 4 miles east of London, in Greater London. Anywhere in SE10, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Greenwich is one of 764 places in Greater London on our list.
Anyone looking for washroom sealing in SE10, SE3 and SE8 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Buildings on Cade Road, Webb Road and Creek Road are within our area. You’ll find Greenwich on or near the A2203 and A2211. Nearby places we also cover include Maze Hill (1 mile north-east), Vanbrugh Park Estate (1 mile east), Blackheath (1 mile south-east), Westcombe Park (1 mile east) and Isle of Dogs (1 mile north-west) for washrooms and wet areas. Further afield, our area takes in London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).
Local landmarks in Greenwich
Locally, jobs take us to sites close to The Plume of Feathers pub, John Roan School and Royal School of Naval Architecture and Marine Engineering and the streets around them. Nearby too are Island Gardens (0.6 miles north-west) and St. Paul's (1.1 miles west). There’s a railway station in Greenwich itself: Maze Hill station. Nearby you will also find Greenwich Castle (less than half a mile south-west) and Greenwich District Hospital (0.5 miles north-east). For a walk, there’s Tower Hill and Creekside Discovery Centre.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Leave signs up until the cure time is over
- Note failing joints building by building
- Report faulty extraction promptly
- 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 get faulty extract looked at.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well, so reseal when you first spot a split.
What sets the cost
To price the job, we consider:
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- The size and state of each joint
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- The asbestos register, for older buildings
- The postcode of the building
- The type of building and who uses it
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a few hours for one toilet block, with bigger buildings phased across a number of visits. Planning a London job such as one in Greenwich starts with access. Give us the hours we can be on site and we will schedule to suit.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- 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
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Greenwich: questions and answers
Can you take on a job at a hospital such as Blackheath Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Do you work in hospitals, clinics and care homes?
We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Is it possible to just clean mouldy silicone?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
When can showers be used after new sealant?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.
