Washroom sealing near Seasalter

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

Keeping the joints sound

A few simple habits keep the new joints working:

  • Note failing joints building by building
  • Keep washrooms out of use until we say the sealant has cured
  • Brief cleaning staff to treat joints gently
  • Don’t leave an open joint at a basin or tray

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

How a job runs

When we get to site, 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 usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Jobs in and around smaller places like Seasalter are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

Toilets, showers and kitchens around Seasalter

Seasalter is within about 1 mile of the coast, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. There are a number of hotels within about 2 miles of Seasalter. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Church halls and community buildings, such as those at Seasalter Christian Centre, have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a hotel such as The Crescent Turner Hotel (0.9 miles south-east of Seasalter), resealing en suites a few rooms at a time keeps the rest available. Student showers at universities like University of Kent, 4.5 miles to the south-east of Seasalter, see more use than most, and their silicone shows it.

Seasalter is about 2 miles west of Whitstable, in Kent. Seasalter sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Kent coverage takes in 931 places, large and small. There’s a separate page for London, roughly 48 miles from Seasalter.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What the job involves on each surface

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Panel boards already damaged by water
  • Hollow tiles or loose panels behind the joint
  • A dripping waste or valve behind a panel

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Questions we’re asked in Seasalter

Can work at a site such as University of Kent fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a hospital such as Whitstable and Tankerton Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Is colour matching possible?

It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
