Washroom sealing near Darland

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

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Water escaping beneath the floor rather than through a joint
  • Vanity carcasses that have swollen
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

What we seal

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

About our washroom sealing in Darland

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. The enquiries we see most involve gaps where vanity tops meet the wall and panel joints letting water behind, across kitchens and tea points, IPS panels and cubicles and vanity units and basins. For commercial sealant work in Darland, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Darland, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Darland can sit alongside others in a wider programme across Medway.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Darland can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached
  • Share your working hours and any access restrictions

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email the details over.

Wet areas in Darland’s workplaces

Darland lies within about 3 miles of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. Darland is about 30 miles from central London, 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.

Halls of residence and teaching buildings at universities such as University for the Creative Arts - Rochester, 2.2 miles to the north-west of Darland, are easiest to reseal during vacations. At a college such as MidKent College Gillingham Campus, 2.3 miles to the north of Darland, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For a site such as Medway Maritime Hospital, 1.4 miles to the north-west of Darland, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Darland is about 1 mile south-west of Gillingham, in Medway. Commercial clients in Darland use us for work on washrooms and wet areas, as part of our coverage of Medway. We work across 54 places in Medway. For work in that direction, see our London page, about 30 miles away.

What happens if it’s left?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Halls, stores and units around places like Darland may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Darland: questions and answers

Will you work in a care home in Darland without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Is Darland too small for you to travel to?

Not at all. Darland is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Is colour matching possible?

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

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Share your site rules when you send details
  • Avoid scourers and harsh descalers on silicone
  • Include joints in routine washroom inspections
  • Leave signs up until the cure time is over

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
