How we handle washroom sealing in New Charlton
For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we’ll confirm with the quote. If you’re dealing with stained or open joints at kitchen sinks and worktops and open joints along basins and vanity units, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in New Charlton it comes down to the same thing: the right product in a properly prepared joint.
In a London area such as New Charlton, 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.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email us and we’ll arrange a return visit.

Do you need washroom sealing in New Charlton?
Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.
Most enquiries start with one or more of the following:
- Users noticing mouldy joints
- Mould spotting along silicone joints
- Open joints along basins and vanity units
- Split or peeling sealant at shower trays
At a college such as Shooters Hill Sixth Form College (1.6 miles south-east of New Charlton), washroom and kitchen sealant is best renewed in the holidays or in phases during term.
Questions to ask before you book
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- Who will actually carry out the work
- How the existing material will be dealt with
What the job involves on each surface
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below, and we will say if the trouble looks to be beneath the floor.
Basins and vanity tops
Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Washroom sealing around New Charlton: how the place shapes the job
London offices and hotels typically can’t close all their washrooms at once, which is why the work is split into phases agreed in advance. The 2 miles around New Charlton include three care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible.

Halls of residence and teaching buildings at universities such as Ravensbourne University London, 1.5 miles to the north-west of New Charlton, are easiest to reseal during vacations.

FAQs: New Charlton
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Would you work within a site like Queen Elizabeth Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
What’s the quickest route to a quote?
It works in 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.
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 check the ventilation isn’t the cause.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Why deal with it now?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. 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 New Charlton can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
