Where floor joints take the most wear near Merchiston
Merchiston lies within about 3 miles 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. The east of Scotland, where Merchiston is, gets less rain than the west. Frost and winter road salt still work into open joints in car parks and yards. Resealing before the cold months helps protect the edges.
Campuses like Edinburgh Napier University - Merchiston Campus, under half a mile south-west of Merchiston, mix old and new buildings, with movement joints wherever they meet. For an estate such as Astley Ainslie Hospital, 0.7 miles south-east of Merchiston, the joints in ramps, decks and long building elevations all need attention over time. At places like Blackford Business Park (1 mile south-east of Merchiston), joints are sealed a section at a time so operations carry on.

Expansion joint sealing in Merchiston
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Merchiston. Site teams most often ask us about spalled or broken joint edges in floors and decks and expansion joints split through the centre of the bead, across precast concrete panel joints, brickwork movement joints and blockwork control joints. A specialist sealant contractor works differently from a general builder: in Merchiston, that means joint design, primers and backing rod as standard.
Scotland’s cities have multi-storey car parks, shopping centres, university and hospital estates, all with movement joints in decks, floors and walls. Failed joints let water in, and repeated frost then works on the edges.
A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How the job changes by surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.
How a job runs
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 move on in phases so staff and visitors can carry on around us. For premises in Merchiston, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Note which joints were done, when, and with what
- Keep scrapers and ploughs from dragging across joint sealant
- Treat a small split as a warning, not a cosmetic issue
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Barriers left in place until then protect the finish.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.
Why act early in Merchiston
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. Failed sealant in a shared building in Merchiston can affect more than one owner. Fixing it promptly keeps repairs small.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

Your questions answered
Does a coastal location like Merchiston affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
