Wet areas in Sanderstead’s workplaces
Busy London buildings need some toilets open at all times, which is why the work is split into phases agreed in advance. There are several hotels within about 2 miles of Sanderstead. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.
For centre management at a site such as Whitgift Centre, 2.9 miles to the north of Sanderstead, washroom work is planned around footfall. En suites at hotels like Selsdon Park Hotel (to the east of Sanderstead) are cleaned daily, which wears silicone over time. At a hospital like Purley War Memorial Hospital (1.5 miles west of Sanderstead), patient and staff washrooms are best done in short phases agreed with the ward.

Washroom sealing in Sanderstead, done properly
In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. If you’re dealing with gaps where vanity tops meet the wall and panel joints letting water behind, we can put it right, whatever the surface. A single leaking joint is often how a building in Sanderstead first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we’ll come back to it.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Report faulty extraction promptly
- Brief cleaning staff to treat joints gently
- Report split joints at trays and basins early
- Mention any site permits or estates rules at quote stage
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
FAQs: Sanderstead
Do you take on work at healthcare sites like Purley War Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will our hotel in Sanderstead need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.
Is old silicone taken out first?
We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Yes. Sanderstead is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. To discuss a job, ring 01277 525 020 or use the quote form.
Cost factors for washrooms and wet areas
We price every job individually. The main factors are:
- How accessible the joints are
- How much there is to seal
- Travel to remote or island sites
- Induction, permit and paperwork requirements
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Whether an asbestos survey exists
- Your programme or deadline
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
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. Anti-mould sanitary silicone is the standard choice.
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.
How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a job in Sanderstead, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
Before we start on site
- Warn occupants and staff about the work
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Fittings that move too much to hold a bead
- Water from plumbing, not from a joint
- Water escaping beneath the floor rather than through a joint
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.
