Washroom sealing for Biggin sites

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

What the job involves on each surface

Healthcare and care settings

In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed as well as site permits.

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. They are resealed with anti-mould sanitary silicone.

Washroom sealing in Biggin, 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 kitchens and tea points, accessible toilets and changing rooms and vanity units and basins, and the usual reasons a site gets in touch are kitchen worktop joints that can’t be kept clean and shower tray joints that have opened up. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Biggin, that means joint design, primers and backing rod as standard.

Community buildings around smaller places like Biggin have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Biggin clients

Do you take on work at healthcare sites like Gravesham Community Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you work in occupied care homes around Biggin?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. If others near Biggin need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Tell us which areas need to stay in use
  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs

Advice

What happens if it’s left?

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. For buildings around smaller places like Biggin, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • Constructionline member
  • RAL and finish matching where the product range allows
  • Work to your specification and the manufacturer’s guidance

Wet areas in Biggin’s workplaces

The sea is no more than about 2 miles from Biggin, and seaside hospitality usually has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. There are three care or nursing homes within about 2 miles of Biggin. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs.

For a hall at a building such as Church of St Mary, resealing the kitchen and toilets can be fitted between bookings. For a site such as Gravesham Community Hospital, which lies south of Biggin, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Biggin is about 2 miles east of Grays, in Thurrock. Across the RM16 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Thurrock, 27 places are covered, including Biggin. We also cover London, some 20 miles away.

After the work

To get the most from the new sealant:

  • Respect the cure time before reopening each room
  • Tell us about infection-control or permit rules before we quote
  • Add sealant joints to planned maintenance checks
  • Keep a record of which washrooms need attention

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

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Do you need washroom sealing in Biggin?

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.

Clients typically get in touch after noticing something like this:

  • Complaints from staff, guests or users about tired washrooms
  • Failed joints along IPS and cubicle panels
  • Sealant laid over old silicone and now peeling
  • Mould spotting along silicone joints

On an industrial estate such as Star Industrial Estate, less than half a mile to the north of Biggin, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

What your quote should include

  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
