Need washroom sealing in Upper Edmonton?
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- 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.
- 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.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work

Washroom sealing in Upper Edmonton
In a busy washroom, the sealant usually gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. If you have failed joints along IPS and cubicle panels and sealant laid over old silicone and now peeling, we can help, whatever the surface. Looking for mastic applicators who cover Upper Edmonton? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
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.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Your questions answered
Do hotels near Upper Edmonton have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Can work in a care setting near Upper Edmonton go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.
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. That’s what makes the new joint last.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we will set out a timescale with the quote.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Leaks through tanking or membranes below the finishes
- A dripping waste or valve behind a panel
- Vanity carcasses that have swollen
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Urinals and WCs
- IPS panels and cubicles
- Kitchens and tea points
- Accessible toilets and changing rooms
- Vanity units and basins
- Showers, trays and wet room floors
Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites around Upper Edmonton. One quote can cover more than one site, which keeps the paperwork simple.
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.
What sets the cost
What shapes the price:
- Which sealant the job calls for
- Working within restricted access windows
- The total length or number of joints
- How much existing material needs removing
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- The site address and postcode
- Drawings or a marked-up plan, if available
- A wide shot and a close-up of the area
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email the details over.

What else we do in Upper Edmonton
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep washrooms out of use until we say the sealant has cured
- Don’t leave trays and floors sitting wet
- Keep extract fans working and vents clear
- Keep a record of which washrooms need attention
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
Washroom sealing in Upper Edmonton: the local picture
A number of hotels sit less than 2 miles from Upper Edmonton. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time.
For a hall at a building such as St Mary's Church, resealing the kitchen and toilets can be fitted between bookings. Toilets at colleges like Haringey Sixth Form College (to the south-west of Upper Edmonton) take heavy use from students and staff alike.

Signs you need washroom sealing in Upper Edmonton
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.
Common reasons buildings call us in:
- Discoloured joints around urinals and WC pans
- Washrooms that look worn because of the sealant
- A new bead over an old one coming away
- Sealant lifting along a tray edge
Halls of residence and teaching buildings at universities such as University of Portsmouth Walthamstow Campus (to the south-east of Upper Edmonton) are easiest to reseal during vacations.
