How we handle washroom sealing in Broom Hill
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you’re dealing with urinal joints that look unhygienic and panel joints letting water behind, we can help, whatever the surface. Searching for sealant specialists in Broom Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
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.
Our workmanship is guaranteed for 12 months, in Broom Hill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Washroom sealing in Broom Hill: the local picture
A 2-mile radius around Broom Hill takes in a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.
At a university such as University of Greenwich Avery Hill Campus, 4.6 miles to the north of Broom Hill, summer is the usual window for resealing residence bathrooms. At a college such as Bromley College, 2.8 miles west of Broom Hill, washroom and kitchen sealant is best renewed in the holidays or in phases during term.
Broom Hill is about 1 mile south-west of Orpington, in Greater London. Our applicators travel to Broom Hill for work on washrooms and wet areas. We work across 764 places in Greater London, from busy centres to rural villages. Our London page has more on work in that area.

When to call us in Broom Hill
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.
Site and facilities staff are often the first to spot these:
- Urinal joints that look unhygienic
- Resealing that didn’t last because the old bead stayed
- Failed joints along IPS and cubicle panels
- Users noticing mouldy joints
En suites at hotels like TLK Apartments & Hotel (1.2 miles north-east of Broom Hill) are cleaned daily, which wears silicone over time.
What to look for in a quote
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
- Will RAMS and insurance details be available?
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- A room that stays damp because ventilation isn’t working
- Fittings that move too much to hold a bead
- Vanity carcasses that have swollen
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Kitchens and tea points
- Showers, trays and wet room floors
- Vanity units and basins
- Urinals and WCs
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- 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.
Preparing the site
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email us with what you know.
Advice
What sets the cost
We price every job individually. The main factors are:
- Joint width, depth and condition
- The product specified
- Distance, for remote addresses
- Whether old sealant has to be cut out first
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
We can often quote from photos and a few details. It helps to include:
- Drawings or a marked-up plan, if available
- Your programme or deadline
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Questions we are asked in Broom Hill
Does a hotel in Broom Hill need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Do you take on jobs in Broom Hill where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Do you work in Broom Hill?
Yes. Sites across Broom Hill are covered, with one number for every area we cover.
Can you clean the mould off instead of resealing?
Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Inspect washroom sealant regularly
- Note failing joints building by building
- Respect the cure time before reopening each room
- Don’t leave trays and floors sitting wet
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
