Washroom sealing near Somers Town
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking half a day to a day per washroom, depending on the number of fittings. In Somers Town, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Getting the site ready
- Arrange parking or a loading space
- Tell us which areas need to stay in use
- Share your working hours and any access restrictions

How we handle washroom sealing in Somers Town
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, 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. The enquiries we see most involve mould spotting along silicone joints and failed sealant in a tea point or staff kitchen, across showers, trays and wet room floors, vanity units and basins and urinals and WCs. For commercial sealant work in Somers Town, you deal with one contact from quote to sign-off, whether it’s one building or several.
Building managers in Somers Town typically 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.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Building owners, agents and FMs in Somers Town
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Fittings that move too much to hold a bead
- Condensation from failed extract fans
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Vanity units and basins
- IPS panels and cubicles
- Kitchens and tea points
- Accessible toilets and changing rooms
- Urinals and WCs
- Showers, trays and wet room floors
Why it’s worth doing now in Somers Town
Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. 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. Dealing with it early is simpler for everyone.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What else we do in Somers Town
Sanitary sealant for Somers Town buildings
A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time. Somers Town has plenty 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. The work can go floor by floor, agreed with housekeeping.
At a college such as WM College (under half a mile north-west of Somers Town), washroom and kitchen sealant is best renewed in the holidays or in phases during term. For centre management at a site such as Brunswick Centre, 0.6 miles to the south-east of Somers Town, washroom work is planned around footfall.
Somers Town is about 1 mile north-west of St Pancras, in Greater London. We cover Somers Town and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Somers Town is one of 764 places we cover in Greater London.

Your questions answered
Can you cope with the access rules in a London building?
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. All of Greater London is inside the ULEZ, and our planning allows for it
Would you work within a site like St. Pancras Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What sealant do you use in washrooms?
It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.
Do you need washroom sealing in Somers Town?
Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.
Things that usually lead to an enquiry:
- Mould spotting along silicone joints
- Sealant laid over old silicone and now peeling
- Urinal joints that look unhygienic
- Open joints at the base of cubicle panels
On an industrial estate such as Roman Way Industrial Estate, 1.1 miles to the north-east of Somers Town, staff toilets, showers and canteens are where sanitary sealant takes the most wear.
