Washroom sealing in Picketts Lock, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. We work on kitchens and tea points, showers, trays and wet room floors and accessible toilets and changing rooms, and what we’re called in for most is sealant lifting along a tray edge and complaints from staff, guests or users about tired washrooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Picketts Lock it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Don’t leave trays and floors sitting wet
  • Clean sealant with gentle products and a soft cloth
  • Leave signs up until the cure time is over
  • Inspect washroom sealant regularly

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Sanitary sealant for Picketts Lock buildings

There are seven care or nursing homes within about 2 miles of Picketts Lock. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible. Picketts Lock has a number of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

Where you are responsible for a hall attached to a building such as All Saints' Church, its kitchen and toilets need sealant that stays cleanable. Clinical washrooms at sites like North Middlesex University Hospital (2 miles south-west of Picketts Lock) are scheduled with the ward so the room is out of use for as little time as possible.

Should maintenance staff do it?

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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For a job in Picketts Lock, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

What we need from you

  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

How to choose a sealant contractor

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • A room that stays damp because ventilation isn’t working
  • Water from plumbing, not from a joint
  • Swollen or delaminated boards behind panels or vanity tops

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Joints and surfaces we work on

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