Floor joint sealing in Trinity
We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Each job is priced from the metres of joint, their condition and the access windows we get and the figure is fixed before work begins. If you are dealing with scruffy, dirty joint lines on a shop or showroom floor and sealant pulled out along a truck route, we can help. 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.
In Scotland’s cities, buildings from car parks and malls to university and hospital estates rely on movement joints. When the sealant goes, water and grit get in, and a Scottish winter makes it worse.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Trinity
Can you work at a site such as North Leith Sands Industrial Estate, by Trinity?
Yes, sites like North Leith Sands Industrial Estate are within our area, along with the rest of Trinity. Photos and a short description are enough for a first look.
Does the sea air around Trinity change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
How do we get a quote for floor joints?
Approximate metres of joint, photographs of typical and worst areas, and a floor plan let us give a quick quote. For larger floors, a site visit is often best so speak to us on 01277 525 020 or use the quote form to set one up.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Aftercare for building managers
A few simple habits keep the new joints working:
- Treat loading bay joints first if they’re failing
- Keep photographs of joints that look like they’re failing
- Check joint lines on busy aisles regularly
- Remind operators to lift rather than drag
If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.
Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas and keeps on top of the rest.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Quoting for work in Trinity
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Removal of failed or old sealant
- Access and working height
- How much there is to seal
- Induction, permit and paperwork requirements
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Your programme or deadline
- Access details, including height
- The asbestos register, for older buildings
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Warehouse floors and decks around Trinity
Trinity lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Less than 3 miles from Trinity there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
For a centre such as Granton Retail Park, 1 mile west of Trinity, the service yard and car park joints usually need attention first. Estates like North Leith Sands Industrial Estate (to the east of Trinity) combine warehouse slabs, yards and loading bays, all with joints under wheels. Large sites such as Western General Hospital (Edinburgh), 1.6 miles to the south-west of Trinity, have car parks, service roads and long elevations with movement joints in brick and panels.
Trinity is about 2 miles north of Edinburgh, in Edinburgh. Looking for floor joint sealing in Trinity? We can help. Our Edinburgh coverage takes in 174 places, large and small.

On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. In a Scottish city, kerbside space and loading need planning, especially near the centre. Shared closes, stairs and the property factor may need to be part of the plan.
- We walk the floor and mark up joint widths, edge damage and traffic routes.
- The treatment and the zones are set out in a fixed quote.
- Old fill and packed debris come out until both faces are sound.
- We extract the dust and prime the faces if the product needs it.
- The joint is filled to its specified depth and trimmed level.
- Zones reopen once cured and the work moves on.
What we need from you
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Have the specification and drawings to hand

Related advice
How the job changes by surface
Forklift and pallet-truck routes
Open route joints are hard on equipment and drivers. Filling them gives a smoother run and saves the edges.
Semi-rigid joint fillers
A semi-rigid filler is stiff enough to hold the arrises up when wheels cross. They allow only small movement so timing matters on newer slabs.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Broken concrete either side of the joint
- Unstable slabs moving under traffic
- Damaged or worn floor coatings and screeds
If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.
