Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Will you plan work around the academic year at somewhere like Kingston University Roehampton Vale Campus?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you work in Merton?
Yes. We take on work across Merton.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email the details over. Include photos or drawings if you have them.
When can showers be used after new sealant?
Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.
Washroom sealing for commercial buildings in Merton
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs, and the failures we are asked to look at most are panel joints letting water behind and kitchen worktop joints that can’t be kept clean. Facilities teams, main contractors and managing agents in Merton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In a London area such as Merton, commercial washrooms in offices, hotels and leisure buildings see constant use. 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What else we do in Merton
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-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.
- 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.
- 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.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Arrange parking or a loading space
- Tell staff and tenants when we will be in
- Send your site hours and access windows

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Washroom sealing in Merton: the local picture
A London building with hundreds of occupants can’t lose every washroom for a day, so we phase the work core by core or floor by floor with the building manager. The area within 2 miles of Merton holds plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Clinical washrooms at sites like St George's Hospital, 1.1 miles to the north-east of Merton, are scheduled with the ward so the room is out of use for as little time as possible. At a university such as Kingston University Roehampton Vale Campus, 3.1 miles to the north-west of Merton, summer is the usual window for resealing residence bathrooms. For a hotel such as Antoinette Hotel, under half a mile to the north-west of Merton, resealing en suites a few rooms at a time keeps the rest available.
Merton is about 1 mile south-east of Wimbledon, in Greater London. Our applicators travel to Merton for work on washrooms and wet areas. Our Greater London coverage takes in 764 places. Sites around London have their own page, roughly 7 miles from Merton.
Work on washrooms and wet areas is covered throughout SW19, whatever the building. Streets here include High Path, Pincott Road and Hayward Close, and sites on any of them can send details for a fixed quote. You will find Merton on or near the A24, so getting applicators and materials to site is simple. Just outside Merton, we also work in Merton Abbey (1 mile east), South Wimbledon (1 mile north-west), Colliers Wood (1 mile east), Tooting Bec (1 mile north-east) and Summerstown (1 mile north). Further afield, our area takes in London (7 miles north-east), City of Westminster (7 miles north), Marylebone (7 miles north), Kensington (6 miles north), St Pancras (8 miles north) and Shoreditch (9 miles north-east).
Landmarks near Merton
Around Merton, our work takes us to commercial buildings near The Nelson Arms, Wimbledon School of Art and Wandle Park and the streets around them. For rail, the closest station is Haydons Road station, roughly 0.8 miles north of the centre. Other landmarks nearby include Southside Wandsworth (2.8 miles north) and St George's Hospital (1.1 miles north-east). Green spaces nearby include Henman Hill and Merton Park Green Walks.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Panel boards already damaged by water
- Fittings that move too much to hold a bead
- Leaks through tanking or membranes below the finishes
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
What we seal
- IPS panels and cubicles
- Accessible toilets and changing rooms
- Vanity units and basins
- Kitchens and tea points
- Showers, trays and wet room floors
- Urinals and WCs
Aftercare for building managers
For the best life from the joints:
- Tell us about infection-control or permit rules before we quote
- Report split joints at trays and basins early
- Keep a record of which washrooms need attention
- Clean sealant with gentle products and a soft cloth
Ventilation is half the battle. 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.
Different surfaces, different methods
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
Wet-room floors and floor-to-wall joints
Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
- Clear photos of the problem areas
- What the building is and how it’s used
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send photos by email.
