Washroom sealing near Baltasound

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Fittings that move too much to hold a bead
  • Swollen or delaminated boards behind panels or vanity tops

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

Surfaces we seal

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

Washroom sealing for commercial buildings in Baltasound

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. Most enquiries involve urinal joints that look unhygienic and shower tray joints that have opened up, on urinals and WCs, vanity units and basins and accessible toilets and changing rooms. Whether you call it commercial sealant work, mastic application or joint sealing, in Baltasound it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In smaller Scottish places like Baltasound, commercial washrooms are typically in hotels, pubs, schools, care homes and community halls. Black sealant usually can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When to call us in Baltasound

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

It’s worth sending us details if you spot any of the following:

  • Users noticing mouldy joints
  • Shower tray joints that have opened up
  • Failed joints along IPS and cubicle panels
  • Stained or open joints at kitchen sinks and worktops

Church halls and community buildings, such as those at Kirkhoull, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Their plan for phasing and protecting the area
  • What the guarantee covers, and for how long
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Busy facilities in and around Baltasound

With the shore within about 2 miles, Baltasound counts as a coastal location, and seaside hospitality usually has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, so we plan the work for quieter weeks where possible. Baltasound is on Scotland’s drier eastern side. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.

At a school such as Baltasound Junior High School, changing rooms and kitchens need cleanable joints as much as the toilets. Hotels such as Baltasound Hotel (to the east of Baltasound) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Baltasound is in the Shetland Islands. We send applicators to Baltasound for washrooms and wet areas. Baltasound is one of 63 places we cover in the Shetland Islands.

Anyone looking for washroom sealing in ZE2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on Setters Hill Estate, Curlew Avenue and Cormorant Way or nearby, send details and we will quote for washrooms and wet areas. Close to Baltasound, our area also takes in Haroldswick (3 miles north-east), Clivocast (6 miles south), Cullivoe (6 miles south-west), Houbie (11 miles south) and Camb (12 miles south-west). As one of the bigger centres in the Shetland Islands, Baltasound has a broad mix of commercial, public and industrial buildings. Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Questions we are asked in Baltasound

Which documents can you supply for work in Baltasound?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can you take on a job in Baltasound, on the island?

Yes. Islands are part of our area, Baltasound included. Ferry times and the weather set the plan, so we ask for photos and a full list first.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we’ll say if the trouble looks to be beneath the floor.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

Building owners, agents and FMs in Baltasound

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

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.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Keep extract fans working and vents clear
  • Share your site rules when you send details
  • Inspect washroom sealant regularly
  • Keep a record of which washrooms need attention

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs near Baltasound are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  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. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

What we need from you

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Point out any areas we must not close
