How we handle expansion joint sealing in Harthill
We have been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. The enquiries we see most involve movement joints with split or torn sealant and new sealant over old, now failing, across brickwork movement joints, cladding panel joints and podiums and floor movement joints. Looking for mastic applicators who cover Harthill? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For outside joints near Harthill, the Scottish weather sets the timetable: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Harthill, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- 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, 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.
- Each joint is inspected and handed over with our 12-month guarantee.

What else we do in Harthill
Questions about Harthill
Is a hospital such as Tippethill Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Harthill outside your area?
No. Places such as Harthill are covered as much as the big towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.
Can you seal car park deck joints?
Yes. These joints take wheels, salt and water, so product choice matters.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How the job changes by surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
When to call us in Harthill
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
Look out for the following:
- Previous reseals laid over old sealant
- Expansion joints split through the centre of the bead
- Joints packed with grit and debris
- Joints where the bead has lost adhesion
If you manage units on an estate such as Harthill Industrial Estate (0.6 miles west of Harthill), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Check joints after long freezing spells
- Reopen bays and walkways only after the stated cure time
- Keep racking legs and heavy point loads off floor joints
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
