About our washroom sealing in North Cray
Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you’re dealing with sealant lifting along a tray edge and mould spotting along silicone joints, we can help. Searching for sealant specialists in North Cray? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
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.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or send photos by email and we will arrange a return visit.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Act on the first split you see at a shower tray
- Keep a record of which washrooms need attention
- Share your site rules when you send details
- Leave signs up until the cure time is over
Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Should maintenance staff do it?
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re 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.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Before we start on site
- Explain the parking and delivery arrangements
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs

Wet areas in North Cray’s workplaces
The 2 miles around North Cray include seven care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home. A number of hotels sit less than 2 miles from North Cray. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Student showers at universities like University of Greenwich Avery Hill Campus, 2.8 miles to the west of North Cray, see more use than most, and their silicone shows it. Office toilets at parks like Old Bexley Business Park, 0.9 miles north-east of North Cray, take steady weekday use, and mouldy silicone soon shows.

Questions about North Cray
Must a hotel around North Cray close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Will you work in a care home in North Cray without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
What happens if old sealant might contain asbestos?
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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you need to remove the old sealant?
The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.
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 check the ventilation isn’t the cause.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Hollow tiles or loose panels behind the joint
- Panel boards already damaged by water
- Water from plumbing, not from a joint

Why it’s worth doing now in North Cray
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Failed sealant in a building in North Cray can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
