How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Give us the access times and building rules for your premises in Trinity, and we will plan the work to suit, phased where areas need to stay in use.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
- Share your working hours and any access restrictions

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Expansion joint sealing for commercial buildings in Trinity
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. The enquiries we see most involve layers of sealant in a movement joint and sealant peeling off one face of the joint, on car park decks and ramps, blockwork control joints and cladding panel joints. A single leaking joint is often how a building in Trinity first comes to us: we look at the rest while we are there and tell you what we find.
Around the edges of Scotland’s cities are warehouses, trade counters and distribution units, each with saw-cut and construction joints under forklifts and pallet trucks. We work in phases with a product suited to the traffic, so operations carry on.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Brickwork and blockwork joints
Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

FAQs: Trinity
Can you work on a hospital site such as Western General Hospital (Edinburgh)?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like North Leith Sands Industrial Estate, close to Trinity?
Yes. We cover Trinity and the area around it, including industrial estates, business parks and retail parks such as North Leith Sands Industrial Estate. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Work for main contractors and building owners
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’ll confirm them with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Trinity. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Traffic, movement and joints around Trinity
With the shore within about 1 mile, Trinity counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Trinity has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Campuses like University of Edinburgh - Holyrood Campus (to the south-east of Trinity) mix old and new buildings, with movement joints wherever they meet. For a centre such as Granton Retail Park, which lies west of Trinity, the service yard and car park joints usually need attention first. For an occupier at a site such as North Leith Sands Industrial Estate, 0.7 miles to the east of Trinity, the joints at loading doors and dock levellers normally see the hardest wear.
Trinity is about 2 miles north of Edinburgh, in Edinburgh. We cover Trinity and the rest of Edinburgh, with the same fixed quotes and 12-month guarantee as everywhere else. Our Edinburgh coverage takes in 174 places, large and small.

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Joints too narrow for the movement, which need redesigning by the engineer
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.
Joints and surfaces we work on
- Car park decks and ramps
- Blockwork control joints
- Podiums and floor movement joints
- Brickwork movement joints
- Precast concrete panel joints
- Cladding panel joints
Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we will plan around it. Failed sealant in a shared building in Trinity can affect more than one owner, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
