Mastic sealing in Greenfield, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you are dealing with window mastic that has split and shrunk and open joints in brickwork or panels, we can put it right, on shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints alike. Most enquiries from Greenfield start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What affects the price in Greenfield
Each job is priced on its own details. The main factors are:
- Induction, permit and paperwork requirements
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- When you need the work done
- A wide shot and a close-up of the area
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email drawings and photos with what you know.
Why act early in Greenfield
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Scottish city buildings take plenty of rain, and failed external joints let it into stone walls and around frames. Renewing them early protects the fabric.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Questions we are asked in Greenfield
Will you take on a block within reach of Shettleston station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Who arranges mastic work on a tenement in Greenfield?
Typically the owners agree it together, and a property factor often handles the arrangements. We can quote to the factor or to the owners, for a single close or a whole block.
Can you send RAMS and CSCS details before starting?
We are 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 do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most, so they often need renewing sooner.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

Greenfield is on Scotland’s wetter western side. Exposed elevations on blocks take a soaking and their mastic shows it. Outside mastic goes on in dry spells, with some flexibility in the programme.
If you own or manage units on a site such as Carntyne Industrial Estate (0.5 miles west of Greenfield), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Site managers at schools like Eastbank Academy can fit frame mastic into the summer works.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.
Do you need mastic sealing in Greenfield?
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
Things that typically lead to an enquiry:
- Movement joints with sealant missing
- Cracked, hardened mastic round windows on a block
- A mix of products and colours from past repairs
- Occupiers reporting cold air round windows
Owners of student blocks near University of Strathclyde, 1.7 miles north-west of Greenfield, can schedule frame and external mastic for the summer vacation.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we’ll work to them.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
