Washroom sealing for commercial buildings in Lochboisdale

You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. We work on accessible toilets and changing rooms, IPS panels and cubicles and kitchens and tea points, and what we are called in for most is resealing that didn’t last because the old bead stayed and sealant stained black around basins and showers. Looking for mastic applicators who cover Lochboisdale? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

For washroom work around Lochboisdale, we plan so every room on the list is done in one trip where possible. Send photos and a room list and we will give a fixed quote.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

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.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Keeping Lochboisdale washrooms open while we work

Lochboisdale lies within about 1 mile of the sea, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. Being on an island, Lochboisdale means planning around ferry times as well as the weather. Knowing how many washrooms there are lets us plan the days on the island.

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

Lochboisdale is in Na h-Eileanan Siar. We cover commercial sites throughout Lochboisdale, for single jobs and planned programmes alike. Lochboisdale is one of 87 places in Na h-Eileanan Siar on our list for washrooms and wet areas.

We take on washrooms and wet areas across the HS8 postcode area, for business premises of every kind. Streets here include Braehead, Calabhaigh and Kenneth Terrace. Just outside Lochboisdale, we also work in Loch Baghasdail (1 mile north), Dalabrog (2 miles north-west), Rubha Ban (5 miles south), Eòlaigearraidh (9 miles south-west) and Cuidhir (12 miles south-west). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.

Lochboisdale: questions and answers

Must every washroom in our Lochboisdale 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’ll tell you how long for the product used.

Which documents can you supply for work in Lochboisdale?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Are you fully insured?

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

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

What do you charge?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or send details through our quote form with a description of the work.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Can weather delay the job?

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.

What happens if it’s left?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Around smaller places like Lochboisdale, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What you get with us

  • RAL and finish matching where the product range allows
  • Joints cleaned back to sound surfaces
  • A Constructionline member, so easy to vet
  • Sealing commercial buildings since 2005

See our cost guide or how we’re accredited.

What we are called out for in Lochboisdale

Panels and vanity units move slightly in use and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

Clients usually get in touch after noticing something like this:

  • Urinal joints that look unhygienic
  • Open joints at the base of cubicle panels
  • Open joints along basins and vanity units
  • Sealant stained black around basins and showers

Hotels such as Lochboisdale Hotel, under half a mile north-east of Lochboisdale, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What to look for in a quote

  • The named product and why it was chosen
  • How the existing material will be dealt with
  • Are they CHAS accredited or on Constructionline?
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Building owners, agents and FMs in Lochboisdale

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, and each stage is agreed with your contact.

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

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Travel to smaller Scottish places like Lochboisdale is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  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. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email the details over if you’d rather talk the job through.

Advice

After the work

Once the work is signed off, a little attention goes a long way:

  • Clear standing water from shower floors where possible
  • Brief cleaning staff to treat joints gently
  • Note failing joints building by building
  • Add sealant joints to planned maintenance checks

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
