About our washroom sealing in Claygate
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. If you have users noticing mouldy joints and shower tray joints that have opened up, we can help, on IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Claygate is the same: the right product in a properly prepared joint.
Halls and community buildings near places like Claygate are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Include joints in routine washroom inspections
- Respect the cure time before reopening each room
- Clear standing water from shower floors where possible
- Keep a record of which washrooms need attention
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.
Washroom sealing around Claygate: what changes locally
Claygate lies roughly 33 miles out from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.
Where you are responsible for a hall attached to a building such as Church of St Margaret, its kitchen and toilets need sealant that stays cleanable. Office toilets at parks like Forstal Business Park, 2.9 miles north-west of Claygate, take steady weekday use, and mouldy silicone soon shows.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Claygate are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We inspect each washroom and record the joints to be resealed.
- You get a fixed quote with the phasing plan.
- The whole of the old bead is removed.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Getting the site ready
- Share the asbestos register for older buildings

Advice
FAQs: Claygate
Must every washroom in our Claygate building shut while you work?
Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Which documents can you supply for work in Claygate?
RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Is it OK to put new silicone on top of the old?
We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.
Is it possible to just clean mouldy silicone?
Typically not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What happens if it’s left?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Converted and older buildings near places like Claygate tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
