Washroom sealing across Watten

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

About our washroom sealing in Watten

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. If you’re dealing with resealing that didn’t last because the old bead stayed and users noticing mouldy joints, we can put it right. Most enquiries from Watten start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around smaller places such as Watten, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Black sealant usually can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.

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.

Keeping Watten washrooms open while we work

The east of Scotland, where Watten is, gets less rain than the west. Inside, ventilation and use decide how fast washroom sealant moulds, whatever the weather.

For buildings around Watten, washrooms can be done in phases so some facilities are always open.

Watten is about 12 miles south-east of Thurso, in Highland. We cover commercial sites throughout Watten. 256 places across Highland fall within our area, Watten among them.

We cover the KW1 postcode districts for washrooms and wet areas. For a building on Station Road, Henderson Square and Achingale Place or nearby, we can quote for washrooms and wet areas. We also cover Gillock (3 miles north-west), Hastigrow (4 miles north), Bower (5 miles north), Reiss (5 miles east) and Haster (6 miles east) for washrooms and wet areas. Nearby towns on our patch include Thurso (12 miles north-west), Wick (8 miles east) and Castletown (9 miles north). Where a site is remote or on an island, travel and materials need planning ahead, so include the location in your enquiry.

Questions about Watten

Is Watten too small for you to travel to?

Not at all. Watten is within our area. We cover the whole of Scotland. Good photographs up front let us bring everything on the first visit.

Which documents can you supply for work in Watten?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

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.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Which silicone is right for commercial washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Where we can, we combine work around Watten with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

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

Preparing the site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Send your site hours and access windows

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or use the quote form.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Respect the cure time before reopening each room
  • Keep extract fans working and vents clear
  • Don’t leave an open joint at a basin or tray
  • Note failing joints building by building

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

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

How the quote is worked out

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Travel to remote or island sites
  • Backing rod, priming and other preparation

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Whether an asbestos survey exists
  • The product your specification calls for

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email drawings and photos.

Building owners, agents and FMs in Watten

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Watten can form part of a wider programme.

What we are called out for in Watten

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and tell you if another trade is needed.

Typical triggers for a call:

  • Resealing that didn’t last because the old bead stayed
  • Failed sealant behind washroom basins
  • Sealant stained black around basins and showers
  • Panel joints letting water behind

In any commercial washroom in or near Watten, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?
  • Who will actually carry out the work
