Washroom sealing for commercial buildings in Lerwick

Not every silicone belongs in a washroom. 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. We work on vanity units and basins, showers, trays and wet room floors and urinals and WCs, and what we are called in for most is split or peeling sealant at shower trays and sealant laid over old silicone and now peeling. Facilities teams, main contractors and managing agents in Lerwick tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Travel to smaller places like Lerwick is planned so the work is finished on one visit. Photos of each washroom and a count of rooms help us quote and plan.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Surface by surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.

Leave it or put it right?

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

FAQs: Lerwick

Does a hotel in Lerwick need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Is Lerwick inside the area you cover, given it’s on an island?

Yes, Lerwick is within the area we cover. Every Scottish council area is within our area. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.

How long does a job like this take?

It depends on the scope, but the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Cost factors for washrooms and wet areas

A fixed quote reflects the actual work. It takes account of:

  • How much there is to seal
  • Phasing around occupants
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email the details over.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. For work around Lerwick, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  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. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Send your site hours and access windows
  • Tell staff and tenants when we will be in
  • Point out any areas we must not close

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email drawings and photos.

Busy facilities in and around Lerwick

With the shore within about 1 mile, Lerwick counts as a coastal location, 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, so resealing in the quieter months keeps rooms ready. A 2-mile radius around Lerwick takes in plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

Office washrooms on sites such as North Ness Business Park (to the north-east of Lerwick) are in use all working day, so resealing is phased to keep some open. Schools such as Anderson High School have toilets, changing rooms and kitchens that are best resealed in the holidays. For a hotel such as The Lerwick Hotel, under half a mile south-east of Lerwick, resealing en suites a few rooms at a time keeps the rest available.

General trades versus a specialist

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
