Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need, and we clear our waste as we work. What matters most for a job in Walderslade is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Advice

Washroom sealing in Walderslade, done properly

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels so they get particular attention. We work on IPS panels and cubicles, vanity units and basins and urinals and WCs, and what we’re called in for most is sealant stained black around basins and showers and gaps where vanity tops meet the wall. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Walderslade is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A place of Walderslade’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Should maintenance staff do it?

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.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Different surfaces, different methods

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.

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.

Questions we’re asked in Walderslade

Will you plan work around the academic year at somewhere like University for the Creative Arts - Rochester?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Must a hotel around Walderslade close while you 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.

Do you work in hospitals, clinics and care homes?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your 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.

Do you use special sealant for toilets and showers?

Sanitary silicone with anti-mould additives in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Water from plumbing, not from a joint
  • Hollow tiles or loose panels behind the joint
  • Water escaping beneath the floor rather than through a joint

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

What affects the price in Walderslade

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Which sealant the job calls for
  • Any access equipment needed
  • Phasing around occupants
  • Site requirements such as inductions and permits

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Your programme or deadline
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email the details over.

Why deal with it now?

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Pricing washrooms and wet areas depends on quantities, condition and access. Call for a quote.
