How we handle mastic sealing in Holyrood
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on window and door perimeters on blocks, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is old repairs sealed over failed mastic and no planned programme for sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Holyrood it comes down to the same thing: the right product in a properly prepared joint.
Housing associations and councils in Scotland’s cities manage large estates of flats and maisonettes. A planned programme deals with failed mastic across an estate, block by block.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered
How do tenement owners in Holyrood get shared-part mastic done?
Work on shared parts is usually agreed by the owners, often through a property factor. Send details and photographs, and we’ll quote to whoever is arranging it.
Does a coastal location like Holyrood affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Is Holyrood in your area?
Yes. Sites across Holyrood are covered, and the same phone number covers every area.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

Blocks and managed buildings in Holyrood
The sea is no more than about 2 miles from Holyrood. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. The 2 miles around Holyrood include seven care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
If you own or manage units on a site such as Meadowbank Shopping Park, 0.8 miles north-east of Holyrood, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Owners of student blocks near University of Edinburgh - Holyrood Campus (to the south of Holyrood) can schedule frame and external mastic for the summer vacation.
Holyrood is about 1 mile north-east of Edinburgh, in Edinburgh. Our applicators travel to Holyrood for work on mastic joints, handled exactly as we handle every other area. Across Edinburgh, 174 places are covered, including Holyrood.
Business premises anywhere in EH8, EH1 and EH7 are within our area for mastic joints. For a building on High Street, Calton Road and Hutton Road or nearby, send details and we’ll quote for mastic joints. Just outside Holyrood, we also work in Canongate (1 mile north-east), Dumbiedykes (1 mile south-east), Buccleuch (1 mile south), Greenside (1 mile north) and Old Town (1 mile south-west). A short drive away, we cover Queensferry (9 miles west), Southhouse (4 miles south), Gilmerton (4 miles south-east), Muirhouse (3 miles north-west), Slateford (3 miles south-west) and Gracemount (3 miles south).
Local landmarks in Holyrood
We work on buildings around The World's End pub, Scottish Poetry Library and Holyrood Park, among other places. There’s a railway station in Holyrood itself: Edinburgh Waverley station. Nearby you’ll also find Royal Public Dispensary of Edinburgh (less than half a mile west) and People's Story Museum (less than half a mile north-east). Green spaces nearby include Dunsapie Loch and Salisbury Crags.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.
Joints and surfaces we work on
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
Signs you need mastic sealing in Holyrood
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
What tends to prompt an enquiry:
- Repeated reactive repairs to the same buildings
- Patchy repairs in mismatched sealant
- Water getting in round frames after rain
- Window mastic that has split and shrunk
Blocks of flats and mixed-use buildings often cluster around stations such as Edinburgh Waverley station (under half a mile west of Holyrood) and their window and balcony mastic tends to age at the same rate across a building.

Building owners, agents and FMs in Holyrood
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Encourage occupiers to report problems at frames
- List the paperwork your organisation requires when you send details
- Prioritise elevations facing the weather
- Reduce knocks to communal area joints
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Work on a big city site in Scotland typically involves inductions and permits. Tell us the rules and we will work to them.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Let building users know which areas are affected
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance
Quotes
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Advice
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
