Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
A few simple habits keep the new joints working:
- Keep scrapers and ploughs from dragging across joint sealant
- Record the sealant used and the date in the O&M file
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Plan racking layouts so feet don’t land on a joint
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
How we handle expansion joint sealing in Blackburn
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. Workmanship is backed by our 12-month guarantee. If you have new sealant over old, now failing and torn sealant in brick or block movement joints, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Blackburn, that means joint design, primers and backing rod as standard.
Around smaller Scottish places like Blackburn, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we’ll come back to it.

For managing agents and facilities managers
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Leave it or put it right?
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. 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.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What the job involves on each surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
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 your contact hears from us before we move to the next area.

- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.

Advice
Common questions from Blackburn clients
Is Blackburn too far out for you?
No. Places such as Blackburn are covered as much as the big towns. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like Mosshall Industrial Estate, close to Blackburn?
Yes. We cover Blackburn and the area around it, including industrial estates, business parks and retail parks such as Mosshall Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can staff carry on working while you’re here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
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.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first since each needs a different fix.
Traffic, movement and joints around Blackburn
Less than 3 miles from Blackburn there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Blackburn is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Sealing them in drier months limits winter damage.
For an occupier at a site such as Mosshall Industrial Estate, 0.5 miles to the south-west of Blackburn, the joints at loading doors and dock levellers normally see the hardest wear. At places like Whitehill Industrial Estate, 0.6 miles north of Blackburn, joints are sealed a section at a time so operations carry on.

What we are called out for in Blackburn
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Most enquiries start with something like this:
- Joints where the bead has lost adhesion
- Car park joints leaking onto vehicles below
- Chipped joint edges on forklift routes
- Weathered movement joint sealant that no longer flexes
Hospital campuses such as Tippethill Hospital (2.6 miles west of Blackburn) grow in stages, leaving movement joints wherever new blocks meet old.
