About our washroom sealing in Mail

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Site teams most often ask us about discoloured joints around urinals and WC pans and sealant lifting along a tray edge, on kitchens and tea points, urinals and WCs and IPS panels and cubicles. Looking for mastic applicators who cover Mail? We have been sealing commercial buildings since 2005.

Around smaller places such as Mail, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Mould grows into sealant in any wet room that doesn’t dry out, and the answer is removal and a fresh bead of anti-mould silicone.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Washroom sealing in Mail: the local picture

Mail is within about 1 mile of the coast, 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, so we plan the work for quieter weeks where possible. Mail is in the east of Scotland, which is drier than the west. Drier weather outside doesn’t help a washroom with poor extraction, where mould gets into silicone fast.

For a hall at a building such as Mail Church, resealing the kitchen and toilets can be fitted between bookings.

Mail is about 9 miles south of Lerwick, in the Shetland Islands. Across the ZE2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our the Shetland Islands coverage takes in 63 places.

We take on washrooms and wet areas across the ZE2 postcode area. Nearby places we also cover include Bremirehoull (1 mile north), Cunningsburgh (1 mile north), Aithsetter (2 miles north-east), Sandwick (2 miles south) and Hoswick (3 miles south) for washrooms and wet areas. A short drive away, we cover Lerwick (9 miles north), Sound (8 miles north) and Scalloway (7 miles north). Where a site is remote or on an island, we plan travel and materials carefully.

Common problems we fix in Mail

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water, and they stain, crack or wash out.

Most enquiries start with one or more of the following:

  • Users noticing mouldy joints
  • Urinal joints that look unhygienic
  • Resealing that didn’t last because the old bead stayed
  • Open joints along basins and vanity units

Around Mail, washroom joints are resealed by removing the old silicone completely and laying anti-mould sanitary silicone on dry surfaces.

What your quote should include

  • Whether their applicators hold CSCS cards
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?

Our contractor checklist

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For a building near Mail, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

  • Agree which areas must stay open
  • Send any specification or drawings in advance
  • Tell us what induction or permit system the site runs

Ask for a quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

What happens if it’s left?

A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. For buildings near Mail, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Questions about Mail

Must every washroom in our Mail building shut while you work?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Do you work on the island where Mail is?

Yes. Islands are part of our area, Mail included. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Can you clean the mould off instead of resealing?

Normally not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Will all the toilets be closed at once?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time, then we move on.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What the job involves on each surface

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
