Scotland’s city blocks are largely sandstone or, in Aberdeen, granite, and replacement windows set into those walls need a perimeter sealant that won’t mark the stone.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
FAQs: Thornwood
Can work in a care setting near Thornwood go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Do you work for managing agents with blocks near Partick station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Cost factors for mastic joints
To price the job, we consider:
- How much there is to seal
- Travel to remote or island sites
- Any access equipment needed
- The size and state of each joint
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.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- The site address and postcode
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- Your programme or deadline
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 send photos by email if you’d rather talk the job through.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Thornwood can sit alongside others in a wider programme.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Planned mastic for Thornwood portfolios
Thornwood is in the west of Scotland, the wetter side of the country. Frame mastic on weather-facing sides tends to fail first. Programmes allow for wet days. There are two care or nursing homes within about 2 miles of Thornwood. Care home owners need frame and external mastic kept sound without unsettling residents.
For a school such as Thornwood Primary School, perimeter mastic on windows and doors is a holiday job. If you manage student housing near a university such as University of Glasgow Gilmorehill Campus, 1.2 miles east of Thornwood, the summer turnaround is the time for mastic. Historic properties like Tenement House (2 miles east of Thornwood) show the age of some local stock, where frame mastic must suit soft brick or stone.

Looking after the joints
A few simple habits keep the new joints working:
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
What the job involves on each surface
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Give us the access times and building rules for your premises in Thornwood, so the work can be phased and areas kept in use.
