Washroom sealing in Pimlico, done properly
Not every silicone belongs in a washroom. 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. In food areas, hygienic or food-safe sealants are used where food contact is possible. Most enquiries involve gaps where vanity tops meet the wall and failed joints along IPS and cubicle panels, on accessible toilets and changing rooms, vanity units and basins and IPS panels and cubicles. Most enquiries from Pimlico start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In Pimlico, 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.

What the job involves on each surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.
Why act early in Pimlico
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Quoting for work in Pimlico
We price every job individually. The things that drive the figure:
- Working within restricted access windows
- How much existing material needs removing
- Travel to remote or island sites
- How accessible the joints are
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.
What to include in your enquiry
However big the job, these details speed things up:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email the details over.
What else we do in Pimlico
Keeping Pimlico washrooms open while we work
London offices and hotels normally can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. Plenty of hotels sit less than 2 miles from Pimlico. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest.
For buildings on a site such as Handel Business Centre (0.7 miles south-east of Pimlico), washrooms and tea points can be resealed in phases through the working week. Colleges such as Westminster Kingsway College (to the north-east of Pimlico) have toilets, changing rooms and catering kitchens that can be resealed around term dates.
Pimlico is about 1 mile east of Brompton, in Greater London. Any commercial site in Pimlico is covered, for single jobs and planned programmes alike. 764 places across Greater London fall within our area, including Pimlico.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Your questions answered
Would you work within a site like Gordon Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you take on jobs in Pimlico where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
Do you work in Pimlico?
Yes. We take on work across Pimlico.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
When to call us in Pimlico
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.
Typical triggers for a call:
- Sealant laid over old silicone and now peeling
- Failed sealant in a tea point or staff kitchen
- Gaps where vanity tops meet the wall
- Sealant stained black around basins and showers
Healthcare estates like Gordon Hospital, less than half a mile north-east of Pimlico, expect contractors to follow their permits and cleaning rules in every washroom.
