Mastic sealing in Roslin
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks, and what we are called in for most is the same joint failures repeated across a portfolio and occupiers reporting cold air round windows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Roslin, that means joint design, primers and backing rod as standard.
Around Roslin, 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, and if something we did falls short, we return to it.

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Materials that need asbestos testing before work
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Frames that are rotten, warped or broken
If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Roslin: questions and answers
Is Roslin too far out for you?
Not at all. Roslin is within our area. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you cover business parks and estates near Roslin, such as Bilston Glen Industrial Estate?
Yes, sites like Bilston Glen Industrial Estate are within our area, along with the rest of Roslin. Photos and a short description are enough for a first look.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Common problems we fix in Roslin
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Typical triggers for a call:
- Complaints coming in block by block
- The same joint failures repeated across a portfolio
- Cracked, hardened mastic round windows on a block
- Open joints in brickwork or panels
Property owners at sites such as Bilston Glen Industrial Estate (to the north of Roslin) can have mastic renewed between lettings.
What to look for in a quote
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Travel to smaller Scottish places like Roslin is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Send your site hours and access windows
- Agree which areas must stay open
- Have the specification and drawings to hand

For owners and agents in Roslin
Roslin is in the east of Scotland, which is drier than the west. Frost and condensation on winter mornings can still delay outside mastic. Programmes allow for that
Blocks of flats and mixed-use buildings often cluster around stations such as Eskbank station (3.7 miles north-east of Roslin) and their window and balcony mastic tends to age at the same rate across a building. Historic properties like Melville Castle, 3.4 miles to the north-east of Roslin, show the age of some local stock, where frame mastic must suit soft brick or stone.
Roslin is about 3 miles north-east of Penicuik, in Midlothian. Commercial clients in Roslin can call on us for mastic joints. Across Midlothian, 34 places are covered, Roslin among them. Sites around Edinburgh have their own page, roughly 6 miles from Roslin.
We take on mastic joints across the EH25 postcode area, whatever the building. We cover commercial and managed buildings on Main Street, Station Road and Widnell Square. Main routes into Roslin include the B7003, which helps when planning parking and deliveries for the job. If your building is just outside Roslin, we cover Bilston (1 mile north-west), Rosewell (1 mile east), Auchendinny (1 mile south-west), Loanhead (1 mile north) and Polton (2 miles east). A short drive away, we cover Bonnyrigg (3 miles east), Dalkeith (5 miles north-east), Penicuik (3 miles south-west), Gorebridge (5 miles east), Newtongrange (4 miles east) and Mayfield (5 miles east).
Around Roslin
Roslin’s nearest station is Eskbank station, roughly 3.7 miles north-east. Well-known places in the area include Princess Margaret Rose Orthopaedic Hospital (3 miles north) and Glencorse Museum (1.6 miles south-west). For a walk, there’s Edgelaw Reservoir and The New Leaf Co-op.
Why it’s worth doing now in Roslin
Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
