Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How we handle washroom sealing in Southall
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. Where food contact is possible, we use a hygienic, food-safe grade. Most enquiries involve urinal joints that look unhygienic and a new bead over an old one coming away, on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms. Searching for sealant specialists in Southall? We’ve been sealing commercial buildings since 2005.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Southall can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We agree which washrooms close and when.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Before we start on site
- Warn occupants and staff about the work
- Move anything stored against the joints
- For older buildings, check the asbestos register before work

Washroom sealing in Southall: the local picture
Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time. Southall has a good number of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Colleges such as Acorn College, less than half a mile to the north-east of Southall, have toilets, changing rooms and catering kitchens that can be resealed around term dates. On a healthcare site such as Ealing Hospital, 1.4 miles east of Southall, washroom work starts with the infection-control team’s sign-off.
Southall is about 3 miles west of Ealing, in Greater London. We send applicators to Southall for washrooms and wet areas, handled exactly as we handle every other area. 764 places across Greater London fall within our area, Southall among them. We also cover London, around 12 miles from Southall.

Why it’s worth doing now in Southall
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- A room that stays damp because ventilation isn’t working
- Failed tanking beneath a wet-room floor or behind tiles
- Panel boards already damaged by water

FAQs: Southall
Can you work around term dates at a campus such as University of London?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on jobs in Southall where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When to call us in Southall
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Any of the following is a good reason to get the joints checked over:
- Failed sealant in a tea point or staff kitchen
- Sealant lifting along a tray edge
- Gaps where vanity tops meet the wall
- Complaints from staff, guests or users about tired washrooms
At a university such as University of London, 2.9 miles to the south-east of Southall, summer is the usual window for resealing residence bathrooms.
What your quote should include
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- How they handle RAMS and site documents
- What level of public liability insurance do they hold?
