Washroom sealing near Crowhurst

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Site requirements such as inductions and permits
  • Phasing around occupants
  • The size and state of each joint
  • Removal of failed or old sealant

A quote for washrooms and wet areas depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Details that help us quote

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

  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Clear photos of the problem areas

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

About our washroom sealing in Crowhurst

In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. If you’re dealing with open joints at the base of cubicle panels and users noticing mouldy joints, we can put it right, on urinals and WCs, accessible toilets and changing rooms and IPS panels and cubicles alike. One point of contact handles commercial sealant work in Crowhurst from the first photos to the final walk-round, for single jobs and planned programmes alike.

Farm shops, cafés and venues in converted rural buildings around places like Crowhurst have busy toilets and kitchens. We plan the work around bookings and opening times.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Crowhurst can sit alongside others in a wider programme.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Questions about Crowhurst

Is a smaller place like Crowhurst outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Will all the washrooms in our Crowhurst building be closed at once?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or email us. Include photographs or drawings if you have them.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For a building around Crowhurst, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Preparing the site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Quotes

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, ring 01277 525 020 or email a schedule or drawings.

Keeping the joints sound

To get the most from the new sealant:

  • Mention any site permits or estates rules at quote stage
  • Clean sealant with gentle products and a soft cloth
  • Report split joints at trays and basins early
  • Keep extract fans working and vents clear

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

When to call us in Crowhurst

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Most enquiries start with something like this:

  • Shower tray joints that have opened up
  • Open joints at the base of cubicle panels
  • Complaints from staff, guests or users about tired washrooms
  • Gaps where vanity tops meet the wall

For a hall at a building such as Church of St George, resealing the kitchen and toilets can be fitted between bookings.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Their plan for phasing and protecting the area
  • Whether primer will be used where the manufacturer specifies it
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
