Common problems we fix in Portlethen
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
Most enquiries start with something like this:
- Arrises breaking up along floor joints
- Joints packed with grit and debris
- Rain penetration at brick or block movement joints
- Expansion joints split through the centre of the bead
Large sites such as Aberdeen Trades Hospitals, 6 miles north of Portlethen, have car parks, service roads and long elevations with movement joints in brick and panels.

Expansion joint sealing in Portlethen, done properly
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. 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 for buildings in Portlethen. We work on car park decks and ramps, brickwork movement joints and cladding panel joints, and what we’re called in for most is new sealant over old, now failing and damp inside where a wall movement joint has failed. Searching for sealant specialists in Portlethen? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
For outside joints near Portlethen, the Scottish weather sets the timetable: dry faces and the right temperature are essential, so dates have some give. Internal floors can be done whenever suits the site.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Looking after the joints
For the best life from the joints:
- Put movement joints on the planned maintenance inspection round
- Keep stones and debris out of open joint lines
- Keep product details with the building records for the next reseal
- Check joints after long freezing spells
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
Slabs, ramps and loading bays in Portlethen
The sea is no more than about 1 mile from Portlethen. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Less than 3 miles from Portlethen there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
In a school such as Portlethen Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Another example is Portlethen Industrial Estate, less than half a mile north-east of Portlethen, where floors and yards would be done in stages around the occupiers.
Portlethen is about 6 miles south of Aberdeen, in Aberdeenshire. We send applicators to Portlethen for movement joints, handled exactly as we handle every other area. Our Aberdeenshire coverage takes in 179 places, from busy centres to rural villages. For work in that direction, see our Aberdeen page (6 miles or so).
We cover the AB12 postcode districts for movement joints. If your site is on Mosside Drive, Muirend Road and Dunvegan Place or close by, send details and we’ll quote for movement joints. Portlethen sits on or close to the A92, useful when we plan access and materials. We also cover Badentoy Park (1 mile north-west), Portlethen Village (1 mile south-east), Findon (1 mile east), Cammachmore (2 miles south-west) and Marywell (2 miles north-east) for movement joints. Nearby towns on our patch include Westhill (9 miles north-west), Stonehaven (7 miles south-west), Banchory (13 miles west), Kintore (14 miles north-west), Newmachar (14 miles north) and Balmedie (13 miles north). As one of the bigger centres in Aberdeenshire, Portlethen has a broad mix of commercial, public and industrial buildings.
Around Portlethen
We work on buildings around Portlethen Academy. There’s a railway station in Portlethen itself: Portlethen station. A little further out are Pitfoddels Castle (3.8 miles north) and Blairs College (3.3 miles north-west). For a walk, there’s Loirston Loch and Portlethen Moss.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. For work around Portlethen, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Send any specification or drawings in advance
- Point out any areas we must not close

Your questions answered
Do you take on work at healthcare sites like Aberdeen Trades Hospitals?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can being near the sea in Portlethen affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Are expansion joints and movement joints the same thing?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Leave it or put it right?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.
