About our washroom sealing in Bethersden

In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we’ll confirm with the quote. We work on kitchens and tea points, accessible toilets and changing rooms and IPS panels and cubicles, and what we are called in for most is open joints along basins and vanity units and washrooms that look worn because of the sealant. Facilities teams, main contractors and managing agents in Bethersden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural businesses near smaller places such as Bethersden, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What affects the price in Bethersden

Each job is priced on its own details. The things that drive the figure:

  • Removal of failed or old sealant
  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • The type of building and who uses it
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • The postcode of the building

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Bethersden, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Send any specification or drawings in advance

Getting a fixed quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Bethersden: questions and answers

Which documents can you supply for work in Bethersden?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will the toilets in our Bethersden building be out of use?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Do you cover Bethersden?

Yes. Bethersden falls within our area, and the simplest way to start is to phone 01277 525 020 or email drawings and photos.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you follow the specification on our project?

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

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Maintenance after handover

After handover, these steps help:

  • Don’t leave an open joint at a basin or tray
  • Mention any site permits or estates rules at quote stage
  • Keep washrooms out of use until we say the sealant has cured
  • Keep a record of which washrooms need attention

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.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job with more phasing to plan.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Swollen or delaminated boards behind panels or vanity tops
  • Water escaping beneath the floor rather than through a joint

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Surfaces we seal

  • Accessible toilets and changing rooms
  • Vanity units and basins
  • IPS panels and cubicles
  • Showers, trays and wet room floors

Common problems we fix in Bethersden

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

Look out for the following:

  • Sealant laid over old silicone and now peeling
  • Discoloured joints around urinals and WC pans
  • Gaps where vanity tops meet the wall
  • Shower tray joints that have opened up

Where you’re responsible for a hall attached to a building such as Church of St Margaret, its kitchen and toilets need sealant that stays cleanable.

Before you book anyone

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Will failed sealant be removed rather than covered?
  • The terms of the workmanship guarantee
