If you have users noticing mouldy joints and discoloured joints around urinals and WC pans, we can help, on urinals and WCs, vanity units and basins and kitchens and tea points alike. One point of contact handles commercial sealant work in Tipner from the first photos to the final walk-round, for single jobs and planned programmes alike.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Work in places the size of Tipner is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Flag any permit to work we will need
  • Tell us which areas need to stay in use
  • Tell us your opening times and when work is allowed

Washroom sealing in Tipner: the local picture

With the shore within about 1 mile, Tipner counts as a coastal location, and seaside hospitality typically has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, so we plan the work for quieter weeks where possible. At about 64 miles from central London, Tipner is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

For a hotel such as The Avenue Hotel, which lies north-east of Tipner, resealing en suites a few rooms at a time keeps the rest available. For a campus such as University of Portsmouth - North Zone, which lies south of Tipner, showers in residences and washrooms in teaching blocks can be programmed around term dates. Healthcare washrooms on sites such as Queen Alexandra Hospital, 2.3 miles to the north of Tipner, are resealed area by area, under the site’s own infection-control rules.

Tipner is about 1 mile north-west of Portsmouth, in Portsmouth. We cover commercial sites throughout Tipner, for single jobs and planned programmes alike. 19 places across Portsmouth fall within our area, including Tipner.

How the job changes by surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Swollen or delaminated boards behind panels or vanity tops
  • Fittings that move too much to hold a bead

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Cost factors for washrooms and wet areas

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first
  • Access and working height
  • The site’s rules and procedures

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email drawings and photos.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
