FAQs: Greenford
Can you take on a job at a hospital such as The Clementine Churchill Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you phase washroom resealing?
Only the area we’re working in is closed. Rooms go back into use once the sealant has cured and we start the next.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
About our washroom sealing in Greenford
Washroom joints need the right sealant, not whatever is to hand. 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 are dealing with complaints from staff, guests or users about tired washrooms and sealant lifting along a tray edge, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Greenford it comes down to the same thing: the right product in a properly prepared joint.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Greenford
Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. In Greenford, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Greenford can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Confirm the product named in the specification
- Let building users know which areas are affected
- Point out any areas we must not close

The area within 2 miles of Greenford holds several hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The 2 miles around Greenford include two care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone.

When to call us in Greenford
A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.
Any of the following is a good reason to get the joints checked over:
- Sealant stained black around basins and showers
- Open joints along basins and vanity units
- Panel joints letting water behind
- Discoloured joints around urinals and WC pans
Halls of residence and teaching buildings at universities such as University of West London (2.4 miles south-east of Greenford) are easiest to reseal during vacations.
What your quote should include
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- What site paperwork they can supply
- Their pre-qualification and accreditations
How the job changes by surface
Urinals and WC pans
Floor joints around WC pans are often forgotten. They are checked with everything else.
IPS and cubicle panels
Swollen or delaminated boards need replacing and we’ll point out any we see.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Tell us about infection-control or permit rules before we quote
- Include joints in routine washroom inspections
- Don’t leave trays and floors sitting wet
- Keep washrooms out of use until we say the sealant has cured
Each room goes back into use only when the sealant has cured enough. We will tell you when the wet areas can be used, and it helps if signs stay up until then.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
