Washroom sealing near Great Bookham

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Washroom sealing in Great Bookham

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you are dealing with open joints along basins and vanity units and users noticing mouldy joints, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Great Bookham from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In a smaller place such as Great Bookham, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Questions we’re asked in Great Bookham

Is a hospital such as Leatherhead Community Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

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

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

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 do you charge?

Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or email drawings and photos.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How soon can a washroom be used after resealing?

That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.

Leave it or put it right?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. In a smaller place such as Great Bookham, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

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

Why us?

  • Joints cleaned back to sound surfaces
  • CHAS accredited contractor
  • Workmanship guaranteed for 12 months
  • Constructionline member for supplier checks

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • A room that stays damp because ventilation isn’t working
  • Swollen or delaminated boards behind panels or vanity tops
  • Hollow tiles or loose panels behind the joint

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

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

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a site in Great Bookham, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Let us know about inductions and permits
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Schools such as The Dawnay School have toilets, changing rooms and kitchens that are best resealed in the holidays. For a site such as Leatherhead Community Hospital, 2.5 miles north-east of Great Bookham, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Add sealant joints to planned maintenance checks
  • Brief cleaning staff to treat joints gently
  • Clear standing water from shower floors where possible
  • Tell us about infection-control or permit rules before we quote

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Different surfaces, different methods

Urinals and WC pans

Floor joints around WC pans are often forgotten. We include them in the survey.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.
