Washroom sealing for businesses in Sandwick
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep washrooms out of use until we say the sealant has cured
- Note failing joints building by building
- Don’t leave trays and floors sitting wet
- Clean sealant with gentle products and a soft cloth
Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
Washroom sealing in Sandwick
In a busy washroom, the sealant typically gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have resealing that didn’t last because the old bead stayed and panel joints letting water behind, we can put it right, on urinals and WCs, kitchens and tea points and accessible toilets and changing rooms alike. A single leaking joint is often how a building in Sandwick first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places such as Sandwick, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Mould grows into sealant in any wet room that doesn’t dry out, and the answer is removal and a fresh bead of anti-mould silicone.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
Why act early in Sandwick
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.
A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

A few photos plus some basic facts will normally do. It helps to include:
- Your programme or deadline

What we are called out for in Sandwick
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.
Any of the following is a good reason to get the joints checked over:
- Open joints along basins and vanity units
- Split or peeling sealant at shower trays
- A new bead over an old one coming away
- Urinal joints that look unhygienic
Hotels such as County Hotel (1.2 miles west of Sandwick) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What else we do in Sandwick
Sanitary sealant for Sandwick buildings
Sandwick sits close to the coast, within about 1 mile, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. A 2-mile radius around Sandwick takes in a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.
On an industrial estate such as Parkend Industrial Estate (0.5 miles south-east of Sandwick), staff toilets, showers and canteens are where sanitary sealant takes the most wear. Church halls and community buildings, such as those at Stornoway High Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
Sandwick is about 1 mile south-east of Stornoway, in Na h-Eileanan Siar. Sandwick sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Sandwick is one of 87 places in Na h-Eileanan Siar on our list.
Work on washrooms and wet areas is covered throughout HS1 and HS2. Buildings on Stoneyfield, East Street and Olivers Brae are within our area for washrooms and wet areas. Close to Sandwick, our area also takes in Plasterfield (1 mile north), Sanndabhaig (1 mile east), Steinis (1 mile north), Stornoway (1 mile north-west) and Branahuie (1 mile east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you phone 01277 525 020 or email us.

Sandwick: questions and answers
Can you take on a job at a hospital such as Western Isles Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a hotel in Sandwick 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.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you reseal washrooms in healthcare buildings?
Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Tell us who will meet us and how to get in at your building near Sandwick. We’ll confirm the plan with the fixed quote.
- We survey each room, count the joints and note anything behind them that needs another trade.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Point out any areas we must not close
