Washroom sealing in Key's Green

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

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Hollow tiles or loose panels behind the joint
  • Failed tanking beneath a wet-room floor or behind tiles
  • Mould caused by poor ventilation, which will return until the extract is fixed

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Washroom sealing for commercial buildings in Key's Green

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. The enquiries we see most involve urinal joints that look unhygienic and sealant stained black around basins and showers, across IPS panels and cubicles, accessible toilets and changing rooms and vanity units and basins. Most enquiries from Key's Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Rural businesses near smaller places such as Key's Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered

Can you work on a hospital site such as Tunbridge Wells Hospital at Pembury?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do we have to close all our washrooms in Key's Green for resealing?

Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Which silicone is right for commercial washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Will all the toilets be closed at once?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Brief cleaning staff to treat joints gently
  • Leave signs up until the cure time is over
  • Make sure washroom ventilation is running
  • Add sealant joints to planned maintenance checks

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For a building around Key's Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed

How the job changes by surface

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.

IPS and cubicle panels

Swollen or delaminated boards need replacing, and any we come across will be pointed out.

What affects the price in Key's Green

Before we quote, we look at:

  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • When you need the work done
  • Clear photos of the problem areas

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
