Washroom sealing in Harringay, done properly
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. Most enquiries involve sealant laid over old silicone and now peeling and stained or open joints at kitchen sinks and worktops, on kitchens and tea points, urinals and WCs and IPS panels and cubicles. Most enquiries from Harringay start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building managers in Harringay usually need some facilities open throughout. 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.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Panel boards already damaged by water
- Mould caused by poor ventilation, which will return until the extract is fixed
- Fittings that move too much to hold a bead
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly.

What else we do in Harringay
Sanitary sealant for Harringay buildings
Busy London buildings need some toilets open at all times, so resealing goes floor by floor, agreed with the facilities team. There are four care or nursing homes within about 2 miles of Harringay. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Work is agreed with the manager, around residents’ routines.
At a college such as Capital City College, 1.2 miles east of Harringay, washroom and kitchen sealant is best renewed in the holidays or in phases during term. At a university such as American University in London, 1.6 miles to the south-west of Harringay, summer is the usual window for resealing residence bathrooms. Toilets at places like Arena Shopping Park (less than half a mile south of Harringay) are cleaned constantly, which is hard on silicone.

FAQs: Harringay
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.
Can work at a site such as American University in London fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
What will the job cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
Do you phase washroom resealing?
We phase it so users always have somewhere to go. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.
Do you do washroom sealing in healthcare settings?
Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- 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.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Point out parking and an unloading spot
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in

Advice
What the job involves on each surface
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.
Healthcare and care settings
In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements as well as site permits.
Site staff or a sealant specialist?
Certain joints really need a specialist: 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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
How the quote is worked out
To price the job, we consider:
- The total length or number of joints
- How much existing material needs removing
- Whether the work must be split into stages
- The site’s rules and procedures
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- The type of building and who uses it
- The site address and postcode
To get a fixed quote, call 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.
