Why it’s worth doing now in Craigleith
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. Getting access arranged for a building in Craigleith takes time, so deal with all failing joints while access is up.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

After the work
Keep the joints in good shape with a few simple steps:
- Reopen bays and walkways only after the stated cure time
- Plan racking layouts so feet don’t land on a joint
- Raise snow-clearing blades over deck joints where possible
- Look over external and deck joints after a hard winter
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Warehouse floors and decks around Craigleith
Craigleith 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. Being in the east of Scotland, Craigleith gets less rain than the west coast. Frost and de-icing salt still find their way into open external joints. Sealing them in drier months limits winter damage.
Large sites such as Western General Hospital (Edinburgh), under half a mile west of Craigleith, have car parks, service roads and long elevations with movement joints in brick and panels. Schools such as Broughton High School have movement joints in their walls and floors that are easy to overlook.

Signs you need expansion joint sealing in Craigleith
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
Typical triggers for a call:
- Arrises breaking up along floor joints
- Rain penetration at brick or block movement joints
- Sealant peeling off one face of the joint
- Expansion joints split through the centre of the bead
For estates staff at a university like University of Edinburgh - Lauriston Campus (1.6 miles south-east of Craigleith), building and paving joints are part of the planned maintenance list.

On site: what to expect
We begin with a short walk round with whoever looks after the building, 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. City jobs in Craigleith normally need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.
- We look at the joints, their width and how they’ve failed.
- 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.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in

Advice
Surface by surface
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces, with primer where specified.
Common questions from Craigleith clients
Does the sea air around Craigleith 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.
Is hospital work, at somewhere like Western General Hospital (Edinburgh), something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect joint sealing?
Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Indoor joints can typically carry on regardless.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
