Do you need washroom sealing in Keynor Estate?
Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.
Common reasons buildings call us in:
- Sealant lifting along a tray edge
- Sealant stained black around basins and showers
- Urinal joints that look unhygienic
- Resealing that didn’t last because the old bead stayed
Healthcare washrooms on sites such as St Richard's Hospital, 5.2 miles north of Keynor Estate, are resealed area by area, under the site’s own infection-control rules.

How the job changes by surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use so their sealant tends to fail sooner.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. If others near Keynor Estate need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

Keynor Estate: questions and answers
Is Keynor Estate off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is a hospital such as St Richard's Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you use special sealant for toilets and showers?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.
Cost factors for washrooms and wet areas
Quotes vary with the job. It mainly depends on:
- Travel to remote or island sites
- Phasing around occupants
- Any access equipment needed
- Backing rod, priming and other preparation
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- What the building is and how it’s used
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

After the work
Keep the joints in good shape with a few simple steps:
- Clean sealant with gentle products and a soft cloth
- Leave signs up until the cure time is over
- Make sure washroom ventilation is running
- Act on the first split you see at a shower tray
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.
