What the job involves on each surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
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 flagging broken arrises before sealing.
Expansion joint sealing in Minster
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. If you are dealing with joints where the bead has lost adhesion and joints packed with grit and debris, we can put it right, whatever the surface. Searching for sealant specialists in Minster? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Movement joints on schools, offices and shops in towns like Minster are easy to overlook until water gets in. Once the sealant hardens or splits, water gets into the wall and the joint no longer works.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

After the work
A few simple habits keep the new joints working:
- Clear dirt from joint lines during routine cleaning
- Avoid parking heavy plant or pallets on joint lines
- Act on the first tear or lifting edge rather than waiting
- Inspect movement joints alongside other routine building checks
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can ring 01277 525 020 or email a schedule or drawings and send a picture.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.
Floors, slabs and movement joints in Minster
Minster is within about 2 miles of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. Rainfall across the South East, Minster included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
Another example is Walbrook Business Park, 1.7 miles to the west of Minster, where floors and yards would be done in stages around the occupiers. In a school such as Thistle Hill Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
- Damaged metal nosings or cover plates over a joint

Common problems we fix in Minster
When a bead pulls away from one face, it has lost adhesion. 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.
Things that normally lead to an enquiry:
- Previous reseals laid over old sealant
- Hardened, cracked sealant on exposed facades
- Water getting into the wall through a failed joint
- Water dripping through deck or ramp joints
Hospitals like Sheppey Community Hospital (to the south-west of Minster) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Questions about Minster
Is a hospital such as Sheppey Community Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Minster, such as Marshlands Industrial Estate?
Yes. Estates, retail parks and business parks around Minster, Marshlands Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What happens if it rains on the day?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
How long do sealant joints 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.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Most work in Minster is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Clear stock, furniture or equipment away from the joints
