Common questions from Carndu clients
What site paperwork comes with a job in Carndu?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Is Carndu too far out for you?
No. Small places get the same service as large ones. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Will cleaning remove black mould from sealant?
Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
How soon can a washroom be used after resealing?
Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.
Washroom sealing in Carndu
Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels so they get particular attention. We work on IPS panels and cubicles, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are open joints along basins and vanity units and sealant lifting along a tray edge. Searching for sealant specialists in Carndu? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In smaller Scottish places like Carndu, commercial washrooms are typically in hotels, pubs, schools, care homes and community halls. Black sealant usually can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.
Every job we finish is backed by a 12-month workmanship guarantee, in Carndu as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Hollow tiles or loose panels behind the joint
- Failed tanking beneath a wet-room floor or behind tiles
- Swollen or delaminated boards behind panels or vanity tops

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
What sets the cost
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- The total length or number of joints
- The product specified
- Phasing around occupants
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Rough lengths or quantities, or drawings if you have them
- The type of building and who uses it
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email a schedule or drawings to discuss it first.
Keeping Carndu washrooms open while we work
The sea is no more than about 1 mile from Carndu, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The west of Scotland, where Carndu is, gets more rain than the east. In a damp climate, washrooms that aren’t well ventilated stay wet for longer, and sealant in a room that never dries out moulds faster.
Units at estates like Ardelve Industrial Estate, 1 mile south-west of Carndu, have welfare blocks whose showers and toilets see shift after shift. Hotels such as Dornie Hotel (0.8 miles south-west of Carndu) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.
Carndu is in Highland. Businesses, contractors and managing agents in Carndu use us for work on washrooms and wet areas, as part of our coverage of Highland. We work across 256 places in Highland, from busy centres to rural villages.

Signs you need washroom sealing in Carndu
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and tell you if another trade is needed.
Things that typically lead to an enquiry:
- Discoloured joints around urinals and WC pans
- Sealant lifting along a tray edge
- Mould spotting along silicone joints
- Kitchen worktop joints that can’t be kept clean
Where you’re responsible for a hall attached to a building such as St Duthuc's Roman Catholic Chapel, its kitchen and toilets need sealant that stays cleanable.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
- Their approach to joint depth and backing
- How long is the guarantee, and what does it include?

What the job involves on each surface
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.
Urinals and WC pans
Floor joints around WC pans are often forgotten. They are checked with everything else.
