Washroom sealing across North Sheen
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We inspect each washroom and record the joints to be resealed.
- You get a fixed quote with the phasing plan.
- The whole of the old bead is removed.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.
Getting the site ready
- Explain the parking and delivery arrangements
- Move anything stored against the joints
- For older buildings, check the asbestos register before work

Advice
How we handle washroom sealing in North Sheen
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs, and what we’re called in for most is sealant laid over old silicone and now peeling and split or peeling sealant at shower trays. Looking for mastic applicators who cover North Sheen? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Vanity carcasses that have swollen
- Failed tanking beneath a wet-room floor or behind tiles
- Loose panels, vanity units or tiles, which need fixing first
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Joints and surfaces we work on
- Vanity units and basins
- Urinals and WCs
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Showers, trays and wet room floors
- Kitchens and tea points
What the job involves on each surface
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we’ll plan around them.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.
North Sheen: questions and answers
Is a hospital such as Barnes Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as Richmond American University London?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is it possible to just clean mouldy silicone?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
How soon can a washroom be used after resealing?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.
Building owners, agents and FMs in North Sheen
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
How the quote is worked out
Before we quote, we look at:
- Access and working height
- How much existing material needs removing
- Location, for remote and island sites
- Joint width, depth and condition
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Anything awkward about access or site hours
- Specification clauses that apply
- The postcode of the building
- What the building is and how it’s used
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Washroom sealing around North Sheen: what changes locally
Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time. There are plenty of hotels within about 2 miles of North Sheen. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.
At a hotel such as Kew Gardens Hotel, less than half a mile west of North Sheen, the quieter weeks are the time to reseal bathrooms. Halls of residence and teaching buildings at universities such as Richmond American University London, 1.3 miles north of North Sheen, are easiest to reseal during vacations. For a college such as Ealing and West London College (2.7 miles north-west of North Sheen), half-term and summer give the windows for washroom work.

General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
