Questions we are asked in Henhurst

Is Henhurst off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Would you work within a site like Gravesham Community Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you reseal washrooms in healthcare buildings?

Yes. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What will the job cost?

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

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Washroom sealing in Henhurst, done properly

From one staff toilet in Henhurst to washrooms across a whole estate, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. The enquiries we see most involve split or peeling sealant at shower trays and a new bead over an old one coming away, on showers, trays and wet room floors, vanity units and basins and IPS panels and cubicles. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Henhurst, preparation and product choice get the time they need.

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

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Henhurst may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Related advice

Why act early in Henhurst

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Halls, stores and units around places like Henhurst may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

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.

Why appoint us

  • A Constructionline member, so easy to vet
  • Fully insured, including public liability cover
  • Colours chosen to suit frames, cladding or finishes where possible
  • One number for every site we cover

Read our cost guide and how we’re accredited.

Maintenance after handover

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

  • Keep washrooms out of use until we say the sealant has cured
  • Report split joints at trays and basins early
  • Clean sealant with gentle products and a soft cloth
  • Keep a record of which washrooms need attention

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Mouldy sealant only gets harder to ignore and users notice. Replacing it early keeps the job to a reseal.

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Commercial washrooms in Henhurst

The area within 2 miles of Henhurst holds a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest. Central London is about 22 miles from Henhurst, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

At a college such as North Kent College Gravesend Campus, 2.2 miles to the north of Henhurst, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For buildings on a site such as Lion Business Park, 2.6 miles to the north of Henhurst, washrooms and tea points can be resealed in phases through the working week. Halls linked to places like Church of St Margaret host groups all week, which is hard on kitchen and toilet sealant.
