Mastic sealing for commercial buildings in Hardgate
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you are dealing with brittle perimeter mastic across a building and leaks at window and door perimeters, we can help, on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints alike. Searching for sealant specialists in Hardgate? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around Hardgate, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Leaks from above rather than through a joint
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
How the quote is worked out
These are the things that shape the price:
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
Whether it’s a single area or a whole estate, the same things set the price: 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.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The postcode of the building
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Approximate linear metres or a joint schedule
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.
Different surfaces, different methods
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
Frames, entrances and external joints in Hardgate
Being in the east of Scotland, Hardgate gets less rain than the west coast. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty.

Signs you need mastic sealing in Hardgate
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Typical triggers for a call:
- No planned programme for sealant
- Failed external movement joints
- Old repairs sealed over failed mastic
- Estate-wide sealant that is simply worn out
Churches, halls and community buildings such as Urr Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Why act early in Hardgate
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Around smaller places like Hardgate, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
