How we handle construction mastic in Roslin
The specification and the programme set the job rather than whatever product is to hand. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. Most enquiries involve different trades sealing to different standards and old sealant on a refurbishment that needs stripping before new work, on internal decorators’ caulk, sanitary and kitchen joints and brick and block movement joints. Looking for mastic applicators who cover Roslin? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
External sealing around Roslin depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Joint design decisions that belong to the architect or engineer
- Glazing units that are cracked or misted
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.

New build and refits around Roslin
Roslin is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team. Projects in Roslin follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
Historic houses such as Melville Castle, 3.4 miles to the north-east of Roslin, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New wings at hospitals like Princess Margaret Rose Orthopaedic Hospital (to the north of Roslin) bring long runs of window and panel joints to seal. School extensions, at buildings such as Lasswade High School Centre, typically run to the summer holidays, mastic included.
Roslin is about 3 miles north-east of Penicuik, in Midlothian. We cover commercial sites throughout Roslin, for single jobs and planned programmes alike. Roslin is one of 34 places in Midlothian on our list for mastic packages. Our Edinburgh page has more on work in that area (6 miles or so).

Looking after the joints
For the best life from the joints:
- Get the mastic subcontractor involved early in the programme
- Release areas for mastic once other trades have finished in them
- Stick to the specified sealant rather than a generic substitute
- Protect sealed areas from following trades
Any damage after we have finished should go on the snag list right away. We can return to clear snags before handover, priced as part of the package or separately.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Surface by surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Common questions from Roslin clients
Will you take on work at estates like Bilston Glen Industrial Estate, close to Roslin?
Yes, sites like Bilston Glen Industrial Estate are within our area, along with the rest of Roslin. A few photos and the unit address let us price the work.
Is hospital work, at somewhere like Princess Margaret Rose Orthopaedic Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you do internal caulk as well as external mastic?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.
Does weather affect external mastic work?
External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing so we typically switch to internal work when that happens.
Can you work plot by plot or floor by floor?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and adjusted as things change.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Why it’s worth doing now in Roslin
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
