Questions about Cockfosters
Will our hotel in Cockfosters need to close for the work?
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.
Can you take on a job at a hospital such as Priory Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How long before the toilets can reopen?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.
Will cleaning remove black mould from sealant?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Busy facilities in and around Cockfosters
Four care or nursing homes sit less than 2 miles from Cockfosters. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home. There are a number of hotels within about 2 miles of Cockfosters. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time.
En suites at hotels like The Hadley Hotel (1.2 miles west of Cockfosters) are cleaned daily, which wears silicone over time. Colleges such as Oak Hill College (to the south-east of Cockfosters) have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Leave it or put it right?
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- A room that stays damp because ventilation isn’t working
- Panel boards already damaged by water
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
What we seal
- IPS panels and cubicles
- Urinals and WCs
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Vanity units and basins
- Kitchens and tea points
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a few hours for one toilet block, with bigger buildings phased across a number of visits. All of Greater London is in the ULEZ, and kerbside space in Cockfosters can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Getting the site ready
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Flag any permit to work we’ll need
