Washroom sealing for Grange sites

Washroom sealing in Grange, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. We work on accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles, and the failures we are asked to look at most are split or peeling sealant at shower trays and stained or open joints at kitchen sinks and worktops. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Grange, that means joint design, primers and backing rod as standard.

Halls and community buildings near places like Grange are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Whether old sealant has to be cut out first
  • How accessible the joints are
  • Working within restricted access windows
  • Site requirements such as inductions and permits

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Sending details for a quote

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

  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Your questions answered

Is hospital work, at somewhere like Medway Maritime Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Grange too far out for you?

Not at all. Grange is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

What sealant do you use in washrooms?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is old silicone taken out first?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Do you need washroom sealing in Grange?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

Typical triggers for a call:

  • Stained or open joints at kitchen sinks and worktops
  • Failed joints along IPS and cubicle panels
  • Washrooms that look worn because of the sealant
  • Gaps where vanity tops meet the wall

Units at estates like Beechings Way Industrial Centre (0.5 miles south of Grange) have welfare blocks whose showers and toilets see shift after shift.

What to look for in a quote

  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • How the joint faces will be prepared and primed

Honest limits

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

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes
  • Hollow tiles or loose panels behind the joint

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Surfaces we seal

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

How the job changes by surface

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

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.

Work for main contractors and building owners

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.

Building owners and managing agents use us on everything from one building to a spread of sites around Grange. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Busy facilities in and around Grange

Grange is within about 1 mile of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Washrooms used guest after guest wear their sanitary silicone faster, so resealing in the quieter months keeps rooms ready. Grange lies roughly 30 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.

For a college such as MidKent College Gillingham Campus, 1.7 miles west of Grange, half-term and summer give the windows for washroom work. In a centre such as Pentagon Shopping Centre, 2.4 miles west of Grange, public washrooms are resealed a block of facilities at a time.

Grange is about 1 mile north of Gillingham, in Medway. We send applicators to Grange for washrooms and wet areas, handled exactly as we handle every other area. Grange is one of 54 places in Medway on our list. For work in that direction, see our London page, about 30 miles away.
