Washroom sealing for Hareplain sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Hareplain can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Warn occupants and staff about the work

Washroom sealing for commercial buildings in Hareplain

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, 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. Site teams most often ask us about failed sealant in a tea point or staff kitchen and resealing that didn’t last because the old bead stayed, across showers, trays and wet room floors, IPS panels and cubicles and kitchens and tea points. For commercial sealant work in Hareplain, you deal with one contact from quote to sign-off, whether it’s one building or several.

Farm shops, cafés and venues in converted rural buildings around places like Hareplain have busy toilets and kitchens. We plan the work around bookings and opening times.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Hareplain

Do we have to close all our washrooms in Hareplain for resealing?

Usually only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Do you take on work at healthcare sites like Benenden 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.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote before we start.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How soon can a washroom be used after resealing?

Cure times vary by product and temperature. You’ll get a reopening time for each area before we leave it.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Loose panels, vanity units or tiles, which need fixing first
  • Panel boards already damaged by water
  • Water from plumbing, not from a joint

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

  • Urinals and WCs
  • Showers, trays and wet room floors
  • Kitchens and tea points
  • Accessible toilets and changing rooms
  • Vanity units and basins
  • IPS panels and cubicles

Why act early in Hareplain

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Older rural buildings around Hareplain move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Fully insured
  • Old sealant cut out, never sealed over
  • CHAS accredited
  • Sealing commercial buildings since 2005

See how commercial sealant jobs are priced or how we’re accredited.

Should maintenance staff do it?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When to call us in Hareplain

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

Typical triggers for a call:

  • Stained or open joints at kitchen sinks and worktops
  • Black mould inside silicone joints that cleaning can’t shift
  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels

For a site such as Benenden Hospital, 2.7 miles south of Hareplain, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?
  • What site paperwork they can supply

Questions to ask before you appoint anyone

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages
  • Quantities, in metres or numbers

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.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • The type of building and who uses it
  • Any dates the work must fit around
  • The site address and postcode
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email drawings and photos.
