On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. 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.
- Every room is surveyed and the failed joints listed.
- 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.
What we need from you
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
- Let us know about inductions and permits

How we handle washroom sealing in Hackney
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. If you are dealing with panel joints letting water behind and users noticing mouldy joints, we can help, on accessible toilets and changing rooms, showers, trays and wet room floors and vanity units and basins alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Hackney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Hackney, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Fittings that move too much to hold a bead
- Swollen or delaminated boards behind panels or vanity tops
- Mould caused by poor ventilation, which will return until the extract is fixed
If you are not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.
Joints and surfaces we work on
- Kitchens and tea points
- Accessible toilets and changing rooms
- Urinals and WCs
- Showers, trays and wet room floors
- Vanity units and basins
- IPS panels and cubicles
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Questions we are asked in Hackney
Can you take on a job at a hospital such as Homerton University Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Will our hotel in Hackney need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you guarantee washroom sealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
What the job involves on each surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
Basins and vanity tops
Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.
What happens if it’s left?
A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. In a London building, a failed joint rarely affects only one party: 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.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Commercial washrooms in Hackney
Hackney has a good number of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. In London buildings, toilets and showers generally need to stay partly open, so we phase the work core by core or floor by floor with the building manager.
Toilets at colleges like International College of Musical Theatre, 0.9 miles east of Hackney, take heavy use from students and staff alike. For a campus such as Loughborough University London (1 mile east of Hackney), showers in residences and washrooms in teaching blocks can be programmed around term dates.

When to call us in Hackney
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.
Most enquiries start with something like this:
- Resealing that didn’t last because the old bead stayed
- Discoloured joints around urinals and WC pans
- Kitchen worktop joints that can’t be kept clean
- Complaints from staff, guests or users about tired washrooms
For an occupier at a site such as Bayford Street Industrial Centre, which lies south-west of Hackney, the canteen and welfare facilities need cleanable joints as much as any office.
