Washroom sealing across Godalming

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. Several jobs near Godalming can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Share the asbestos register for older buildings

What we can’t put right

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

  • Condensation from failed extract fans
  • A dripping waste or valve behind a panel
  • Leaks through tanking or membranes below the finishes

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

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

Commercial clients in Godalming

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Looking after the joints

To get the most from the new sealant:

  • Don’t leave trays and floors sitting wet
  • Photograph and log failed joints across the estate
  • Include joints in routine washroom inspections
  • Act on the first split you see at a shower tray

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used and signage stays in place until that time.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

How the job changes by surface

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.

FAQs: Godalming

Do hotels near Godalming have to close for sealant work?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Can you work around term dates at a campus such as University of Surrey - Manor Park Campus?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Will all the toilets be closed at once?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Can you reseal washrooms in healthcare buildings?

Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

What will the job cost?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

General trades versus a specialist

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
