Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
About our commercial sealant contractors in Canongate
Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind. We look before we quote and tell you plainly if sealant won’t solve it. We work on external facade joints, washrooms and tea points and floor and threshold joints, and the usual reasons a site gets in touch are damp patches where an external joint has failed and black mould through washroom sealant that won’t clean off. Searching for sealant specialists in Canongate? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
A lot of what we do in Canongate is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
In Scotland’s cities, commercial premises are packed closely, from stone-fronted offices to shops on the ground floor of tenement blocks. Shop units under tenements can bring the property factor into the picture when the work touches shared parts.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Quoting for work in Canongate
Before we quote, we look at:
- How accessible the joints are
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
- Whether the work must be split into stages
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Sending details for a quote
A few photographs plus some basic facts will normally do. It helps to include:
- Whether the building will be occupied during the work
- The site address and postcode
- Anything awkward about access or site hours
- Your programme or deadline
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
Frontages, fit-outs and joints in Canongate
Canongate is within about 2 miles of the coast. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Where a frontage needs a particular colour, the product still has to suit that exposure. Canongate is in the east of Scotland, which is drier than the west. Cold snaps still affect when external joints can be sealed.
Refits at hotels like Edinburgh Marriott Holyrood Hotel, under half a mile to the south-east of Canongate, bring joints at vanity tops, bars and reception desks that guests see every day. For a shop at a centre such as St. James Centre, under half a mile north-west of Canongate, tidy joints at counters and displays matter as much as the fixtures. Sites a few miles apart, such as Meadowbank Shopping Park and Albion Business Centre, can share one programme and one point of contact.

After the work
A few simple habits keep the new joints working:
- Report cracked or peeling sealant early
- Add sealant to the planned maintenance inspection list
- Check the asbestos register before anyone disturbs old sealant in an older building
- Keep abrasive pads and scrapers off resealed joints
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
Why deal with it now?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. In a tenement or shared city building, water from a failed joint can reach other owners’ property, which makes early repair simpler for everyone. Fixing it promptly keeps repairs small.

Your questions answered
Do you cover business parks and estates near Canongate, such as Meadowbank Shopping Park?
Yes. Estates, retail parks and business parks around Canongate, Meadowbank Shopping Park among them, are all within reach. Photos and a short description are enough for a first look.
Does a hotel in Canongate need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What do you need from us to quote?
Send photographs, drawings or a list of locations. If a visit is needed we’ll book one, and a fixed quote follows.
Do you work directly for building managers?
Yes. You can send details through our quote form.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can areas stay open during the work?
Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Old mastic that tests positive for asbestos
- A dripping trap, valve or pipe behind a fitting
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
