Washroom sealing in Kearsney

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How we handle washroom sealing in Kearsney

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs, and what we are called in for most is gaps where vanity tops meet the wall and stained sealant around pans and urinals. A specialist sealant contractor works differently from a general builder: on jobs in Kearsney, preparation and product choice get the time they need.

Around Kearsney, washroom work typically comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. For a site in Kearsney, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings
  • Agree which areas must stay open

Commercial clients in Kearsney

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Kearsney. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Leave it or put it right?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why clients in Kearsney choose us

  • Public liability insurance in place
  • Over 20 years of commercial sealing
  • Old sealant cut out, never sealed over
  • CHAS accredited contractor

See our cost guide or our accreditations.

Questions we are asked in Kearsney

Is a hospital such as Buckland Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Could you schedule work at a campus like East Kent College for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically 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.

Will you quote for a small job?

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

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Is it OK to put new silicone on top of the old?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Signs you need washroom sealing in Kearsney

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.

Look out for the following:

  • Failed sealant in a tea point or staff kitchen
  • Shower tray joints that have opened up
  • Gaps where vanity tops meet the wall
  • Panel joints letting water behind

For a college such as East Kent College, which lies south-east of Kearsney, half-term and summer give the windows for washroom work.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Wet areas in Kearsney’s workplaces

Kearsney lies within about 3 miles of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, so we plan the work for quieter weeks where possible. At about 64 miles from central London, Kearsney is within reach of the capital, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Healthcare washrooms on sites such as Buckland Hospital, 1.5 miles to the south-east of Kearsney, are resealed area by area, under the site’s own infection-control rules. Where you are responsible for a hall attached to a building such as Church of St Peter and St Paul, its kitchen and toilets need sealant that stays cleanable.

Kearsney is about 1 mile north-west of Dover, in Kent. Across the CT16 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, about 64 miles away.

We take on washrooms and wet areas across the CT16 and CT17 postcode area. For a building on Park Road, Lower Road and The Avenue or nearby, send details and we’ll quote for washrooms and wet areas. Just outside Kearsney, we also work in Temple Ewell (1 mile north), River (1 mile south-east), Whitfield (1 mile north-east), Wolverton (1 mile west) and Dover (1 mile south-east). Further afield, our area takes in Canterbury (12 miles north-west), Folkestone (6 miles south-west), Ramsgate (15 miles north-east), Deal (7 miles north-east), Hythe (10 miles south-west) and Walmer (7 miles north-east).

Local landmarks in Kearsney

We work on buildings around Royal Oak Cottage The Royal Oak Public House, Old Park Hill and Dover Christ Church Academy and the streets around them. There’s a railway station in Kearsney itself: Kearsney station. Nearby you’ll also find Crabble Corn Mill (0.7 miles south-east) and Dover Castle (2.7 miles south-east). Not far away are Dover Western Heights.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Leaks through tanking or membranes below the finishes
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Hollow tiles or loose panels behind the joint

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

What we seal

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