Washroom sealing for Birchett's Green sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Swollen or delaminated boards behind panels or vanity tops
  • A dripping waste or valve behind a panel
  • Water escaping beneath the floor rather than through a joint

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

Where we work in Birchett's Green

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

Washroom sealing in Birchett's Green

In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. The enquiries we see most involve resealing that didn’t last because the old bead stayed and washrooms that look worn because of the sealant, on IPS panels and cubicles, vanity units and basins and urinals and WCs. For commercial sealant work in Birchett's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

Rural businesses near smaller places such as Birchett's Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Note failing joints building by building
  • Avoid scourers and harsh descalers on silicone
  • Mention any site permits or estates rules at quote stage
  • Add sealant joints to planned maintenance checks

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Your questions answered

Is hospital work, at somewhere like Ticehurst House Hospital, something you do?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do we have to close all our washrooms in Birchett's Green for resealing?

Typically 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.

Will cleaning remove black mould from sealant?

Normally not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

How do you choose the sealant?

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.

Cost factors for washrooms and wet areas

Quotes vary with the job. Expect it to depend on:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • Phasing around occupants
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

We can often quote from photographs and a few details. It helps to include:

  • When you need the work done
  • Where the site is, with the postcode
  • The type of building and who uses it
  • A wide shot and a close-up of the area

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Birchett's Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another 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. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Different surfaces, different methods

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.

Church halls and community buildings, such as those at Shover's Green Baptist Chapel, have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a school such as Uplands Community College, washroom and kitchen sealant can be renewed around term dates.

Signs you need washroom sealing in Birchett's Green

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

Common reasons buildings call us in:

  • Complaints from staff, guests or users about tired washrooms
  • Gaps where vanity tops meet the wall
  • Panel joints letting water behind
  • Urinal joints that look unhygienic

On a healthcare site such as Ticehurst House Hospital, 1.1 miles to the south-east of Birchett's Green, washroom work starts with the infection-control team’s sign-off.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply
