About our expansion joint sealing in St Mary's
Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you have chipped joint edges on forklift routes and debris jammed in movement joints, we can put it right. A single leaking joint is often how a building in St Mary's first comes to us: we look at the rest while we’re there and tell you what we find.
In smaller places such as St Mary's, the joints we are asked about sit in workshops, farm sheds, schools and halls. Slabs and yards take vehicles, rain and frost.
What our 12-month guarantee covers is the way we did the job: 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.

Why it’s worth doing now in St Mary's
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind, and a second visit means paying for access again. We can price a patch and a full reseal side by side. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around St Mary's before they leak.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Your questions answered
Will you travel to St Mary's on the island?
Yes. Islands are part of our area, St Mary's included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Can you work on a hospital site such as Balfour Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What happens if it rains on the day?
A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.
What timescale should we allow for resealing expansion joints?
It usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We’ll confirm when each area can be used again.
How much does the work cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Different surfaces, different methods
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around St Mary's, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.

Related advice
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Plan racking layouts so feet don’t land on a joint
- Reopen bays and walkways only after the stated cure time
- Inspect exposed joints once the cold weather has passed
- Clear dirt from joint lines during routine cleaning
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can phone 01277 525 020 or use the quote form and send a picture.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
Floors, slabs and movement joints in St Mary's
St Mary's sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. St Mary's is on Scotland’s drier eastern side. Frost and de-icing salt still find their way into open external joints. Autumn is a sensible time to seal them.
Hospitals like Balfour Hospital, 5.8 miles to the north of St Mary's, have multi-storey or surface car parks whose joints carry vehicles round the clock. For floors and slabs around St Mary's, the product is chosen for the traffic and the movement at each joint.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
