Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Construction mastic for commercial buildings in Heriot
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. We work on floor and skirting junctions, cladding and panel joints and brick and block movement joints, and what we are called in for most is bath and shower joints scraped during the final clean and oversized or tapered gaps around new frames. A single leaking joint is often how a building in Heriot first comes to us: we look at the rest while we’re there and tell you what we find.
In smaller places such as Heriot, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
Every job we finish is backed by a 12-month workmanship guarantee, in Heriot as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
If you are not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs near Heriot are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site

Advice
Mastic packages on Heriot sites
Scotland has its own building regulations, and in Heriot warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant. Heriot is in the east of Scotland, which is drier than the west. Winter mornings can still bring frost and condensation on steel and glass. External dates keep a little give.
On any site in or around Heriot, the mastic follows the specification and the programme. Window perimeters and facade joints around Heriot need correct width, depth and backing rod as much as a neat finish.
Heriot is about 9 miles south-east of Bonnyrigg, in the Scottish Borders. Any commercial site in Heriot is covered. Our the Scottish Borders coverage takes in 91 places. Edinburgh is covered too, some 15 miles away.
Work on mastic packages is covered throughout EH38. If your site is on Heriot Way and Shoestanes Road or close by, send details and we’ll quote for mastic packages. Sites close to Heriot are covered too, including Fountainhall (4 miles south-east), North Middleton (4 miles north-west), Arniston (5 miles north-west), Birkenside (5 miles north-west) and Gorebridge (6 miles north-west).

Cost factors for mastic packages
To price the job, we consider:
- How much existing material needs removing
- Distance, for remote addresses
- Joint width, depth and condition
- The site’s rules and procedures
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
Sending details for a quote
We can often quote from photos and a few details. Please tell us:
- Approximate linear metres or a joint schedule
- Access details, including height
- Whether an asbestos survey exists
- The postcode of the building
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email the details over.
Why deal with it now?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. We’ll say so if a frame itself is the problem. Around smaller places like Heriot, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
