Washroom sealing in St John's Town of Dalry, done properly

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. In food areas, hygienic or food-safe sealants are used where food contact is possible. The enquiries we see most involve stained or open joints at kitchen sinks and worktops and open joints along basins and vanity units, across showers, trays and wet room floors, urinals and WCs and IPS panels and cubicles. Whether you call it commercial sealant work, mastic application or joint sealing, in St John's Town of Dalry it comes down to the same thing: the right product in a properly prepared joint.

Hospitality around smaller Scottish places like St John's Town of Dalry tends to be seasonal, so washroom work is often best planned for quieter months.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near St John's Town of Dalry. That goes into the plan alongside the quote.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A room that stays damp because ventilation isn’t working
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Fittings that move too much to hold a bead

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Share your site rules when you send details
  • Note failing joints building by building
  • Squeegee showers and trays after busy periods
  • Act on the first split you see at a shower tray

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

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.

Cost factors for washrooms and wet areas

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Removal of failed or old sealant
  • Access and working height
  • The product specified
  • Working within restricted access windows

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.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
