Washroom sealing for Sound sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Signs you need washroom sealing in Sound

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

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

  • Sealant lifting along a tray edge
  • Sealant laid over old silicone and now peeling
  • Open joints along basins and vanity units
  • Failed sealant in a tea point or staff kitchen

Hotels such as The Lerwick Hotel (0.8 miles north-east of Sound) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What your quote should include

  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Washroom sealing for commercial buildings in Sound

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Most enquiries involve sealant stained black around basins and showers and gaps where vanity tops meet the wall, on accessible toilets and changing rooms, kitchens and tea points and IPS panels and cubicles. A single leaking joint is often how a building in Sound first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For washroom work around Sound, we plan so every room on the list is done in one trip where possible. 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.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Travel to remote or island sites

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or send photos by email.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking half a day to a day per washroom, depending on the number of fittings. Jobs near Sound are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. First, the phasing is agreed so facilities stay open.
  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

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Share the asbestos register for older buildings

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email us with what you know.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Water from plumbing, not from a joint
  • Fittings that move too much to hold a bead
  • Mould caused by poor ventilation, which will return until the extract is fixed

If you are not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Surfaces we seal

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

Looking after the joints

For the best life from the joints:

  • Respect the cure time before reopening each room
  • Report split joints at trays and basins early
  • Note failing joints building by building
  • Inspect washroom sealant regularly

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

FAQs: Sound

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

Yes. Islands are part of our area, Sound included. We group island work where we can and plan around the crossings.

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

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Can you reseal washrooms in healthcare buildings?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Will cleaning remove black mould from sealant?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Sanitary sealant for Sound buildings

The sea is no more than about 1 mile from Sound, and seaside hospitality normally has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. There are a good number of hotels within about 2 miles of Sound. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.

For a site such as Gilbert Bain Hospital, which lies north-east of Sound, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Schools such as Anderson High School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Sound is about 1 mile south-west of Lerwick, in the Shetland Islands. Across the ZE1 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Sound is one of 63 places we cover in the Shetland Islands for washrooms and wet areas.

Commercial sites across ZE1 are covered for washrooms and wet areas. For a building on Quoys Road, South Road and Oversund Road or nearby, send details and we will quote for washrooms and wet areas.

Sound ranks among the main centres of the Shetland Islands, with offices, shops, schools and other public and commercial buildings, and we cover them all. Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.
