About our expansion joint sealing in Altens
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on precast concrete panel joints, blockwork control joints and podiums and floor movement joints, and the failures we are asked to look at most are arrises breaking up along floor joints and damp inside where a wall movement joint has failed. A single leaking joint is often how a building in Altens first comes to us: we look at the rest while we’re there and tell you what we find.
Around the edges of Scotland’s cities are warehouses, trade counters and distribution units, whose floor joints take forklift and pallet-truck traffic daily. We work in phases with a product suited to the traffic, so operations carry on.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What happens if it’s left?
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. Getting access arranged for a building in Altens takes time, so deal with all failing joints while access is up.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Looking after the joints
To get the most from the new sealant:
- Raise snow-clearing blades over deck joints where possible
- Leave barriers in place until fresh joint sealant has cured
- Inspect exposed joints once the cold weather has passed
- Act on the first tear or lifting edge rather than waiting
Add every elevation, deck and floor joint to your inspection round. 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 speak to us on 01277 525 020 or send photos by email and send a picture.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For premises in Altens, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.
- We start with photographs, 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Tell us your opening times and when work is allowed
- Flag any permit to work we will need
- Move anything stored against the joints

Advice
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Slabs, ramps and loading bays in Altens
Altens 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. Altens is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Autumn is a sensible time to seal them.
At places like Wellington Circle Retail Park, which lies south-west of Altens, joints are sealed a section at a time so operations carry on. A healthcare site such as Albyn Hospital (to the north-west of Altens) depends on car parks, ramps and service yards whose joints take traffic all day.
Altens is about 2 miles south-east of Ferryhill, in Aberdeen. Our applicators travel to Altens for work on movement joints. Our Aberdeen coverage takes in 40 places, from busy centres to rural villages.

Common problems we fix in Altens
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.
Clients normally get in touch after noticing one or more of the following:
- Water dripping through deck or ramp joints
- Spalled or broken joint edges in floors and decks
- Joints packed with grit and debris
- Hardened, cracked sealant on exposed facades
On industrial estates such as Altens Industrial Estate, which lies north-east of Altens, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
- Will RAMS and insurance details be available?
- Health and safety accreditation such as CHAS
What else we do in Altens
Your questions answered
Can being near the sea in Altens affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Do you take on work at healthcare sites like Albyn Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
