Washroom sealing in Biggin Hill, done properly
Washroom joints need the right sealant, not whatever is to hand. 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 IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins, and what we’re called in for most is sealant laid over old silicone and now peeling and stained or open joints at kitchen sinks and worktops. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Biggin Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Washroom sealing in Biggin Hill: the local picture
In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team.
For an occupier at a site such as Biggin Hill Airport Trading Estate, which lies north of Biggin Hill, the canteen and welfare facilities need cleanable joints as much as any office. En suites at hotels like The Landing Hotel (to the north of Biggin Hill) are cleaned daily, which wears silicone over time. Clinical washrooms at sites like Warlingham Park Hospital (2.7 miles west of Biggin Hill) are scheduled with the ward so the room is out of use for as little time as possible.
Biggin Hill is about 6 miles east of Caterham, in Greater London. Across the TN16 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places, large and small. We also cover London, around 14 miles from Biggin Hill.
We cover the TN16 and BR6 postcode districts. If your site is on Rushdene Walk, Mount Pleasant and Stock Hill or close by, we can quote for washrooms and wet areas. Being close to the A233, Biggin Hill is easy to get to with materials and equipment. Sites close to Biggin Hill are covered too, including Aperfield (1 mile south-east), Luxted (1 mile north-east), Berry's Green (1 mile east), Single Street (1 mile east) and Leaves Green (2 miles north).

Local landmarks in Biggin Hill
We work on buildings around Charles Darwin School. The nearest railway station is Woldingham station, roughly 3.8 miles south-west of the centre. Nearby you’ll also find Warlingham Park Hospital (2.7 miles west). The countryside around Biggin Hill includes Betsom's Hill and West Kent Golf Course nature reserve.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Inspect washroom sealant regularly
- Keep extract fans working and vents clear
- Respect the cure time before reopening each room
- Avoid scourers and harsh descalers on silicone
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
Questions about Biggin Hill
Would you work within a site like Warlingham Park Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will all the washrooms in our Biggin Hill building be closed at once?
Normally 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.
How much does the work cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Is old silicone taken out first?
The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.
Leave it or put it right?
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. In Biggin Hill, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Cost factors for washrooms and wet areas
These are the things that shape the price:
- The size and state of each joint
- The site’s rules and procedures
- Any access equipment needed
- How much there is to seal
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- Whether an asbestos survey exists
- Your programme or deadline
- Specification clauses that apply
- Drawings or a marked-up plan, if available
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send details through our quote form.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Preparing the site
- Share your working hours and any access restrictions
- Let us know about inductions and permits
- Warn occupants and staff about the work

Advice
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Swollen or delaminated boards behind panels or vanity tops
- Water from plumbing, not from a joint
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.
