Oval: questions and answers
Does a hotel in Oval need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Can you work on a hospital site such as Gordon Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When can showers be used after new sealant?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
When is resealing likely to be due?
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.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Washroom sealing in Oval
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you have open joints at the base of cubicle panels and failed sealant behind washroom basins, we can help, on accessible toilets and changing rooms, vanity units and basins and IPS panels and cubicles alike. Facilities teams, main contractors and managing agents in Oval tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Building managers in Oval typically need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you.
Our workmanship is guaranteed for 12 months, in Oval as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Planning a London job such as one in Oval starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- 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.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Let us know about inductions and permits
- Have the specification and drawings to hand
- Make sure the joints can be reached

Washroom sealing around Oval: how the place shapes the job
London offices and hotels typically can’t close all their washrooms at once, so resealing goes floor by floor, agreed with the facilities team. Plenty of hotels sit less than 2 miles from Oval. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.
At a college such as Chelsea College of Art & Design, 0.7 miles to the north-west of Oval, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Clinical washrooms at sites like Gordon Hospital, 1 mile north-west of Oval, are scheduled with the ward so the room is out of use for as little time as possible. Office toilets at parks like Handel Business Centre (to the north-west of Oval) take steady weekday use, and mouldy silicone soon shows.

What the job involves on each surface
Changing rooms and gyms
We phase work so not every changing area is closed at once. Phasing follows your site hours and access windows.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade once the whole of the old bead has gone.
After the work
To get the most from the new sealant:
- Keep a record of which washrooms need attention
- Add sealant joints to planned maintenance checks
- Make sure washroom ventilation is running
- Don’t leave trays and floors sitting wet
Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Why act early in Oval
Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. Failed sealant in a building in Oval can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
