Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. If you have sealant laid over old silicone and now peeling and panel joints letting water behind, we can help, on accessible toilets and changing rooms, vanity units and basins and showers, trays and wet room floors alike. Most enquiries from Bentley Heath start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Rural businesses near smaller places such as Bentley Heath, 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.

When to call us in Bentley Heath

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.

Look out for the following:

  • Resealing that didn’t last because the old bead stayed
  • Stained or open joints at kitchen sinks and worktops
  • Gaps where vanity tops meet the wall
  • Sealant lifting along a tray edge

Toilets at places like Spires Shopping Centre (2 miles south of Bentley Heath) are cleaned constantly, so silicone needs to be sound and smooth.

What your quote should include

  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

When it isn’t the sealant

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

  • A dripping waste or valve behind a panel
  • A room that stays damp because ventilation isn’t working
  • Swollen or delaminated boards behind panels or vanity tops

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

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

Quoting for work in Bentley Heath

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • Phasing around occupants
  • The product specified

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

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

  • Specification clauses that apply
  • The site address and postcode
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Clear standing water from shower floors where possible
  • Leave signs up until the cure time is over
  • Photograph and log failed joints across the estate
  • Add sealant joints to planned maintenance checks

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

FAQs: Bentley Heath

Do hotels near Bentley Heath have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Is Bentley Heath too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. If others near Bentley Heath need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  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.

Before we start on site

  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Keeping Bentley Heath washrooms open while we work

Bentley Heath is about 13 miles from central London, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time. There are a number of hotels within about 2 miles of Bentley Heath. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

Where you are responsible for a hall attached to a building such as Church of King Charles and the Martyr, its kitchen and toilets need sealant that stays cleanable. If you manage an office at a site such as Wrotham Business Park, which lies south of Bentley Heath, the washrooms and tea points can be done a floor at a time.
