Busy facilities in and around Liphook

Liphook is about 42 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time. There are a number of hotels within about 2 miles of Liphook. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

Staff changing rooms and patient toilets at places like Holy Cross Hospital (to the east of Liphook) need cleanable, sound silicone. Church halls and community buildings, such as those at St Mary's Church Centre, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Liphook is about 8 miles north-east of Petersfield, in Hampshire. Commercial clients in Liphook use us for work on washrooms and wet areas, as part of our coverage of Hampshire.

Washroom sealing for commercial buildings in Liphook

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. We work on IPS panels and cubicles, kitchens and tea points and showers, trays and wet room floors, and what we’re called in for most is panel joints letting water behind and washrooms that look worn because of the sealant. A specialist sealant contractor works differently from a general builder: in Liphook, that means joint design, primers and backing rod as standard.

Jobs in a smaller place such as Liphook are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Swollen or delaminated boards behind panels or vanity tops
  • Hollow tiles or loose panels behind the joint

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Surfaces we seal

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

Do you need washroom sealing in Liphook?

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old so it peels away quickly.

Site and facilities staff are often the first to spot these:

  • Shower tray joints that have opened up
  • Stained or open joints at kitchen sinks and worktops
  • Mould spotting along silicone joints
  • Failed joints along IPS and cubicle panels

On an industrial estate such as Passfield Industrial Estate, 2.1 miles to the north-west of Liphook, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

How to choose a sealant contractor

Different surfaces, different methods

IPS and cubicle panels

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

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. Several jobs near Liphook can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • Share the asbestos register for older buildings

Maintenance after handover

To get the most from the new sealant:

  • Photograph and log failed joints across the estate
  • Keep washrooms out of use until we say the sealant has cured
  • Squeegee showers and trays after busy periods
  • Don’t leave an open joint at a basin or tray

Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

Common questions from Liphook clients

Can you take on a job at a hospital such as Holy Cross Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Liphook too far out for you?

Not at all. Liphook is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

What do you charge?

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

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Do you guarantee washroom sealing?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

Is old silicone taken out first?

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

Doing it in-house

Certain joints really need a specialist: 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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
