FAQs: Well Hall
Does a hotel in Well Hall need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Will you plan work around the academic year at somewhere like University of Greenwich - Avery Hill?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
About our washroom sealing in Well Hall
Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on showers, trays and wet room floors, kitchens and tea points and vanity units and basins, and what we’re called in for most is failed sealant in a tea point or staff kitchen and users noticing mouldy joints. Most enquiries from Well Hall start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building managers in Well Hall normally need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Well Hall can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- We agree which rooms close and when, so users always have somewhere to go.
- The failed silicone is stripped and every face scraped clean of residue.
- Joints are cleaned, degreased and dried before sealing.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Leaks through tanking or membranes below the finishes
- Condensation from failed extract fans
- Vanity carcasses that have swollen
If you are not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Where we work in Well Hall
- Showers, trays and wet room floors
- Kitchens and tea points
- Accessible toilets and changing rooms
- Vanity units and basins
- IPS panels and cubicles
- Urinals and WCs
Keeping the joints sound
After handover, these steps help:
- Include joints in routine washroom inspections
- Keep extract fans working and vents clear
- Act on the first split you see at a shower tray
- Respect the cure time before reopening each room
Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
What the job involves on each surface
Showers and trays
A tray that rocks or has cracked won’t be fixed by sealant and we flag that beforehand.
Healthcare and care settings
Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we will confirm with the quote.
