Mastic sealing in Thornliebank
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on window and door perimeters on blocks, balcony and threshold joints and communal entrances and stairwells, and what we are called in for most is mastic failing across several blocks on an estate and brittle perimeter mastic across a building. One point of contact handles commercial sealant work in Thornliebank from the first photographs to the final walk-round, whether it’s one building or several.
Around Thornliebank, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

After the work
A few simple habits keep the new joints working:
- Keep bins and bikes away from communal door frames
- Look at the sunniest and most exposed elevations first
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. Around smaller places like Thornliebank, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Where we can, we combine work around Thornliebank with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.

Advice
How the quote is worked out
Each job is priced on its own details. The main factors are:
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- Phasing around occupants
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Clear photographs of the problem areas
- The type of building and who uses it
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
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, ring 01277 525 020 or email a schedule or drawings.
Common questions from Thornliebank clients
Will you take on work at estates like Spiersbridge Business Park, close to Thornliebank?
Yes. Estates, retail parks and business parks around Thornliebank, Spiersbridge Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Thornliebank too far out for you?
No. Places such as Thornliebank are covered as much as the big towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
What do you charge?
There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
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.
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
