About our washroom sealing in Maryland
Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, vanity units and basins and accessible toilets and changing rooms, and the usual reasons a site gets in touch are kitchen worktop joints that can’t be kept clean and shower tray joints that have opened up. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Maryland, that means joint design, primers and backing rod as standard.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions we are asked in Maryland
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Does a hotel in Maryland need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Do you need to remove the old sealant?
We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.
How many days will you need on site?
It depends on the scope, but the work normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Water escaping beneath the floor rather than through a joint
- Water from plumbing, not from a joint
- Swollen or delaminated boards behind panels or vanity tops

Keeping Maryland washrooms open while we work
Plenty of hotels sit less than 2 miles from Maryland. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The 2 miles around Maryland include 25 care or nursing homes. 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.
In a centre such as Stratford Centre, which lies south-east of Maryland, public washrooms are resealed a block of facilities at a time. For a college such as Ebrahim College, which lies south of Maryland, half-term and summer give the windows for washroom work.
Maryland is about 3 miles south of Walthamstow, in Greater London. Maryland sits inside our coverage and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Our Greater London coverage takes in 764 places, large and small.
We take on washrooms and wet areas across the E15, E20 and E7 postcode area. Among the streets we cover are Cam Road, Ward Road and Wise Road. If your building is just outside Maryland, we cover Stratford (1 mile west), East Village (1 mile north-west), Temple Mills (1 mile north-west), West Ham (1 mile south-east) and Holloway Down (1 mile north). Further afield, our area takes in London (5 miles south-west), City of Westminster (7 miles west), Marylebone (6 miles west), Kensington (9 miles west), St Pancras (5 miles west) and Shoreditch (3 miles west).
Around Maryland
We work on buildings around Sarah Bonnell School, West Ham Park and Carpenters Primary School, among other places. There’s a railway station in Maryland itself: Stratford (London) station. Nearby you’ll also find Passmore Edwards Museum (0.5 miles east) and Tower of London (4 miles south-west). The countryside around Maryland includes Old Ford Island and Hollow Pond.
What we’re called out for in Maryland
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.
Most enquiries start with one or more of the following:
- Panel joints letting water behind
- Sealant lifting along a tray edge
- Sealant stained black around basins and showers
- Stained sealant around pans and urinals
Staff changing rooms and patient toilets at places like Homerton University Hospital (to the west of Maryland) need cleanable, sound silicone.

Aftercare for building managers
Once the work is signed off, these steps help:
- Make sure washroom ventilation is running
- Leave signs up until the cure time is over
- Avoid scourers and harsh descalers on silicone
- Tell us about infection-control or permit rules before we quote
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Planning a London job such as one in Maryland starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- We agree which rooms close and when, so users always have somewhere to go.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Each room is handed back once the sealant has had its cure time.
Getting the site ready
- Tell us your opening times and when work is allowed
- Let us know about inductions and permits
- Agree which areas must stay open
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Related advice
Different surfaces, different methods
IPS and cubicle panels
Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.
Urinals and WC pans
Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.
