Washroom sealing for commercial buildings in Back
Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, 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 urinals and WCs, IPS panels and cubicles and accessible toilets and changing rooms, and the failures we are asked to look at most are black mould inside silicone joints that cleaning can’t shift and panel joints letting water behind. One point of contact handles commercial sealant work in Back from the first photos to the final walk-round, whether it’s one building or several.
For washroom work around Back, 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.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Questions about Back
Will you travel to Back on the island?
Yes. Islands are part of our area, Back included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Do we have to close all our washrooms in Back for resealing?
Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Who decides which product is used?
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 your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you need to remove the old sealant?
The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.
Keeping Back washrooms open while we work
With the shore within about 1 mile, Back counts as a coastal location, and seaside hospitality normally has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. Island jobs, Back among them, are planned around the ferry and the forecast. A room count and photographs of each washroom help us bring enough sealant and plan the days.
Clinical washrooms at sites like Western Isles Hospital (to the south-west of Back) are scheduled with the ward so the room is out of use for as little time as possible.
Back is about 6 miles north-east of Stornoway, in Na h-Eileanan Siar. We cover Back and the rest of Na h-Eileanan Siar, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Na h-Eileanan Siar, 87 places are covered, Back among them.
If you need washroom sealing in HS2, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Broadbay View, Rathad na Sgoile and Sraid na H-Eaglaise. We also cover Sulaisiadar (5 miles south-east), Garrabost (5 miles south-east), Na h-Eileanan an Iar (5 miles south), Knock (5 miles south) and Aiginis (5 miles south). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you give us a call on 01277 525 020 or use the quote form.

Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
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, with each stage agreed with your site contact.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Tell us who will meet us and how to get in at your building near Back. That goes into the plan alongside the quote.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.
Getting the site ready

Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Do you need washroom sealing in Back?
Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.
If one of these sounds familiar, it’s time for a closer look:
- Complaints from staff, guests or users about tired washrooms
- Open joints along basins and vanity units
- Split or peeling sealant at shower trays
- Mould spotting along silicone joints
Washrooms near Back get the old silicone stripped out and a fresh anti-mould bead on dry joints.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Can the work be phased to keep areas open?
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
Surface by surface
Healthcare and care settings
Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Records you need can be confirmed with the quote.
Basins and vanity tops
Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
- Panel boards already damaged by water
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Urinals and WCs
- Vanity units and basins
- Accessible toilets and changing rooms
- Kitchens and tea points
- IPS panels and cubicles
- Showers, trays and wet room floors
What happens if it’s left?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. 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. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
