Washroom sealing in Collier Row
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. If you have open joints at the base of cubicle panels and mould spotting along silicone joints, we can help. Searching for sealant specialists in Collier Row? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In a London area such as Collier Row, 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

After the work
Regular inspection catches problems early. In particular:
- Make sure washroom ventilation is running
- Don’t leave an open joint at a basin or tray
- Clear standing water from shower floors where possible
- Inspect washroom sealant regularly
We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used and signage stays in place until that time.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Why act early in Collier Row
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Failed sealant in a building in Collier Row can quickly affect neighbours, tenants or the floor below: 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.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Why appoint us
- 12 months’ guarantee on every job
- Fully insured, including public liability cover
- Work to your specification and the manufacturer’s guidance
- Standard and matched colours in many product ranges

Washroom sealing around Collier Row: what changes locally
Several hotels sit less than 2 miles from Collier Row. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.
For a store at a site such as Rom Valley Retail Park (1.7 miles south of Collier Row), the staff room and customer toilets can be resealed in quiet periods. Toilets at places like Romford Shopping Hall, 1 mile to the south of Collier Row, are cleaned constantly, so silicone needs to be sound and smooth.
Collier Row is about 1 mile north of Romford, in Greater London. We cover commercial sites throughout Collier Row, whether it’s a single job or part of a planned programme. Collier Row is one of 764 places we cover in Greater London for washrooms and wet areas. For work in that direction, see our London page.

Common questions from Collier Row clients
Can you work on a hospital site such as Victoria Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Must a hotel around Collier Row close while you 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.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Is it possible to just clean mouldy silicone?
Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
What do you charge?
Each job is quoted on its own details. To get one, call 01277 525 020 or send details through our quote form.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. In Collier Row, 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.
- 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.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Before we start on site
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand
