About our washroom sealing in Leatherhead

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve failed sealant behind washroom basins and stained sealant around pans and urinals, on vanity units and basins, kitchens and tea points and showers, trays and wet room floors. Facilities teams, main contractors and managing agents in Leatherhead tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Towns the size of Leatherhead have washrooms and wet areas in schools, care homes, offices, gyms and restaurants. Anti-mould sanitary silicone, laid on clean, dry joints, keeps them looking cared for and easy to clean.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What the job involves on each surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed as well as site permits.

Showers and trays

Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.

Doing it in-house

Some joints are best left to specialists: for instance 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.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most work in Leatherhead is one building at a time: a school, a unit, an office or a block. Your photos, drawings or a site visit come first, followed by a fixed quote.

  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 give you a reopening time for every room.

Preparing the site

  • Share your working hours and any access restrictions

Advice

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Which sealant the job calls for
  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Access and working height

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Details that help us quote

A few photos plus some basic facts will normally do. It helps to include:

  • Specification clauses that apply
  • What the building is and how it’s used
  • When you need the work done
  • A wide shot and a close-up of the area

Leatherhead: questions and answers

Can work at a site such as University for the Creative Arts fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is hospital work, at somewhere like Leatherhead Community Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Is Leatherhead in your area?

Yes. Sites across Leatherhead are covered, and the same phone number covers every area.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Do you need washroom sealing in Leatherhead?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

Look out for the following:

  • Open joints at the base of cubicle panels
  • Resealing that didn’t last because the old bead stayed
  • Urinal joints that look unhygienic
  • Users noticing mouldy joints

Halls linked to places like Church of Our Lady and St Peter host groups all week, which is hard on kitchen and toilet sealant.

What to look for in a quote

  • How they’ll work around occupants
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Why deal with it now?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Many buildings in towns like Leatherhead have been extended or altered, so joints between old and new are often the first to go. Resealing them early protects the building behind.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
