Washroom sealing for commercial buildings in Cannon Hill
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. An open joint there lets water track under flooring or behind wall panels so they get particular attention. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and what we are called in for most is washrooms that look worn because of the sealant and split or peeling sealant at shower trays. One point of contact handles commercial sealant work in Cannon Hill from the first photos to the final walk-round, whether it’s one building or several.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. 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.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Washroom sealing around Cannon Hill: what changes locally
A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance. Cannon Hill has eight care or nursing homes no more than 2 miles away. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home.
Customer toilets in retail centres such as Priory Retail Park (to the north-east of Cannon Hill) rarely close, so resealing is phased. Healthcare washrooms on sites such as New Victoria Hospital, 1.9 miles north-west of Cannon Hill, are resealed area by area, under the site’s own infection-control rules.
Cannon Hill is about 1 mile north-west of Morden, in Greater London. Anywhere in SW20, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Cannon Hill is one of 764 places we cover in Greater London. Our London page has more on work in that area (9 miles or so).
Work on washrooms and wet areas is covered throughout SW20, SM4 and KT3. We cover commercial and managed buildings on Aylward Road, Camborne Road and Botsford Road. Nearby places we also cover include Bushey Mead (1 mile north-west), Raynes Park (1 mile west), Wimbledon Chase (1 mile north), West Barnes (1 mile west) and Merton Park (1 mile north-east) for washrooms and wet areas. Further afield, our area takes in London (9 miles north-east), City of Westminster (8 miles north), Marylebone (9 miles north), Kensington (7 miles north), St Pancras (10 miles north-east) and Shoreditch (11 miles north-east).
What’s near Cannon Hill
We work on buildings around The Edward Rayne pub, Cannon Hill Common and Harris Academy Wimbledon and the streets around them. For rail, the closest station is South Merton station, roughly 0.5 miles north-east. Nearby you’ll also find St. Anthony's Hospital (1.5 miles south) and Wimbledon Museum (1.6 miles north). Open spaces near Cannon Hill include Cherry Wood and Henman Hill.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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.
Signs you need washroom sealing in Cannon Hill
Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
If one of these sounds familiar, it’s time for a closer look:
- Sealant stained black around basins and showers
- Discoloured joints around urinals and WC pans
- Stained or open joints at kitchen sinks and worktops
- Open joints at the base of cubicle panels
For an occupier at a site such as Rainbow Industrial Estate, 0.8 miles north-west of Cannon Hill, the canteen and welfare facilities need cleanable joints as much as any office.
Questions to ask before you book
- Their pre-qualification and accreditations
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
Work for main contractors and building owners
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Cannon Hill can form part of a wider programme across Greater London.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
What affects the price in Cannon Hill
These are the things that shape the price:
- Distance, for remote addresses
- Any access equipment needed
- Whether the work must be split into stages
- Backing rod, priming and other preparation
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 to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
- The type of building and who uses it
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or send photos by email with what you know.

Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Fittings that move too much to hold a bead
- A dripping waste or valve behind a panel
- Vanity carcasses that have swollen
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Joints and surfaces we work on

- Showers, trays and wet room floors
- Kitchens and tea points
- IPS panels and cubicles

On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. 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.
- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- Joints are cleaned, degreased and dried before sealing.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work
