About our washroom sealing in Plaistow
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels, so we look at them closely. If you have mould spotting along silicone joints and open joints along basins and vanity units, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Plaistow it comes down to the same thing: the right product in a properly prepared joint.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Hollow tiles or loose panels behind the joint
- Panel boards already damaged by water
- Mould caused by poor ventilation, which will return until the extract is fixed
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Common questions from Plaistow clients
Will you work in a care home in Plaistow without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do you need to remove the old sealant?
The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
What happens if it’s left?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Getting scaffold, permits or access booked in Plaistow takes effort, so it makes sense to deal with every failing joint while access is in place.
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief cleaning staff to treat joints gently
- Don’t leave an open joint at a basin or tray
- Mention any site permits or estates rules at quote stage
- Keep a record of which washrooms need attention
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
Our process
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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Plaistow can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
- Let us know about inductions and permits

Wet areas in Plaistow’s workplaces
Plaistow has 15 care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home. A 2-mile radius around Plaistow takes in several hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Office washrooms on sites such as Chartwell Business Centre, 1.8 miles to the south-east of Plaistow, are in use all working day, so resealing is phased to keep some open. Toilets at places like The Mall (1.2 miles south of Plaistow) are cleaned constantly, so silicone needs to be sound and smooth.
Plaistow is about 1 mile north of Bromley, in Greater London. We cover Plaistow and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. 764 places across Greater London fall within our area, Plaistow among them.

What we’re called out for in Plaistow
Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.
Common reasons buildings call us in:
- Split or peeling sealant at shower trays
- Stained or open joints at kitchen sinks and worktops
- Open joints along basins and vanity units
- Mould spotting along silicone joints
For a site such as Sloane Hospital, 0.9 miles to the south-west of Plaistow, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.
