Washroom sealing across Ealing
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Leave it or put it right?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Washroom sealing in Ealing
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. Site teams most often ask us about stained or open joints at kitchen sinks and worktops and discoloured joints around urinals and WC pans, across accessible toilets and changing rooms, urinals and WCs and showers, trays and wet room floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ealing, that means joint design, primers and backing rod as standard.
Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Planning a London job such as one in Ealing starts with access. Send the building rules and access times with your enquiry.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- 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.
What we need from you
- Explain the parking and delivery arrangements
- Tell staff and tenants when we will be in

What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Water from plumbing, not from a joint
- Mould caused by poor ventilation, which will return until the extract is fixed
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- IPS panels and cubicles
- Urinals and WCs
- Kitchens and tea points
- Showers, trays and wet room floors
- Vanity units and basins
- Accessible toilets and changing rooms
Washroom sealing around Ealing: how the place shapes the job
A 2-mile radius around Ealing takes in plenty of hotels. 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. London offices and hotels normally can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager.
At a hospital like Cygnet Hospital Ealing (0.9 miles north-east of Ealing), patient and staff washrooms are best done in short phases agreed with the ward. Colleges such as Ealing and West London College, less than half a mile east of Ealing, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Questions about Ealing
Will you plan work around the academic year at somewhere like University of West London?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you take on work at healthcare sites like Cygnet Hospital Ealing?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Will cleaning remove black mould from sealant?
Normally not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What else we do in Ealing
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Do you need washroom sealing in Ealing?
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and tell you if another trade is needed.
These are often picked up first by site or facilities staff:
- Panel joints letting water behind
- Urinal joints that look unhygienic
- Users noticing mouldy joints
- Sealant stained black around basins and showers
In a centre such as Westway Shopping Park, 2.5 miles to the north-west of Ealing, public washrooms are resealed a block of facilities at a time.
