What the job involves on each surface
Healthcare and care settings
We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we’ll confirm with the quote.
Urinals and WC pans
Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.
Washroom sealing for commercial buildings in Blackness
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you are dealing with urinal joints that look unhygienic and open joints along basins and vanity units, we can put it right, on accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Blackness, that means joint design, primers and backing rod as standard.
City hotels, restaurants and bars in Scotland need washrooms that look cared for and kitchens that clean easily. We use anti-mould silicone in washrooms and food-safe hygienic sealant at kitchen worktops.
Work we carry out in Dundee comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

Blackness: questions and answers
Will you plan work around the academic year at somewhere like University of Dundee?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Must a hotel around Blackness close while you work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you cover Blackness?
Yes. Blackness falls within our area, and you can speak to us on 01277 525 020 or send details through our quote form to get started.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
What do you charge?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Toilets, showers and kitchens around Blackness
With the shore within about 1 mile, Blackness 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, so we plan the work for quieter weeks where possible. Plenty of hotels sit less than 2 miles from Blackness. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
Units at estates like Mid Wynd Industrial Estate (less than half a mile south-east of Blackness) have welfare blocks whose showers and toilets see shift after shift. In a centre such as Overgate Centre, 0.8 miles east of Blackness, public washrooms are resealed a block of facilities at a time. At a college such as Dundee and Angus College - Kingsway Campus, 1.8 miles to the north of Blackness, washroom and kitchen sealant is best renewed in the holidays or in phases during term.
Blackness is about 1 mile south-west of Dundee, in Dundee. Across the DD1 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 28 places in Dundee, from busy centres to rural villages.
Postcode districts covered here: DD1, DD2 and DD3. Among the streets we cover are City Road, Tait's Lane and Lochee Road. Just outside Blackness, we also work in West End (1 mile south), Dundee (1 mile north-east), Stobswell (1 mile north-east), Woodside (2 miles north-east) and Downfield (2 miles north). A short drive away, we cover Broughty Ferry (5 miles east), Barnhill (5 miles east), Pitkerro (3 miles north-east), Whitfield (3 miles north-east), Balgowan (3 miles north) and Douglas (4 miles east).
What’s near Blackness
We work on buildings around Cox Branch Library, Dudhope Park and Harris Academy. For rail, the closest station is Dundee station, roughly 0.9 miles east of the centre. Well-known places in the area include Dundee Dental Hospital (0.6 miles east) and Tayside Medical History Museum (less than half a mile north-east). Green spaces nearby include Balgay Hill and Trottick Mill Ponds.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Make sure washroom ventilation is running
- Clear standing water from shower floors where possible
- Respect the cure time before reopening each room
- Clean sealant with gentle products and a soft cloth
We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.
Mouldy sealant only gets harder to ignore and users notice. Replacing it early keeps the job to a reseal.
For managing agents and facilities managers
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Blackness. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
What else we do in Blackness
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking half a day to a day per washroom, depending on the number of fittings. For premises in Blackness, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Preparing the site
- Tell us which areas need to stay in use
- Let us know about inductions and permits
- Move anything stored against the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What happens if it’s left?
Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Failed sealant in a shared building in Blackness can affect more than one owner, which makes early repair simpler for everyone. Fixing it promptly keeps repairs small.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
