When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Crumbling edges that would give a new bead nothing sound to grip
- A joint that has to be widened or re-detailed before it can work
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Expansion joint sealing for commercial buildings in Kingsnorth
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. We work on brickwork movement joints, podiums and floor movement joints and cladding panel joints, and what we’re called in for most is brittle, chalky sealant on external joints and water dripping through deck or ramp joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Kingsnorth, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Kingsnorth have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Warehouse floors and decks around Kingsnorth
Kingsnorth is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Kingsnorth has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Phasing is what makes joint work possible on busy sites such as Gallagher Retail Park (1.3 miles north of Kingsnorth): one bay, aisle or car park row at a time. Hospital campuses such as The One Ashford Hospital (to the north-east of Kingsnorth) grow in stages, leaving movement joints wherever new blocks meet old. For a school such as Kingsnorth Church of England Primary School, playground and building joints can be done in the holidays.
Kingsnorth is about 2 miles south of Ashford, in Kent. Any commercial site in Kingsnorth is covered, for single jobs and planned programmes alike. 931 places across Kent fall within our area, Kingsnorth among them. For work in that direction, see our Brighton page.

When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why it’s worth doing now in Kingsnorth
Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex, so it fails quickly. We cut out the old seal and prepare the faces every time. Older rural buildings around Kingsnorth move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Site requirements such as inductions and permits
- The total length or number of joints
- Working within restricted access windows
- How much existing material needs removing
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Whether the building will be occupied during the work
- The postcode of the building
- Any dates the work must fit around
- The asbestos register, for older buildings
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Common questions from Kingsnorth clients
Do you take on work at healthcare sites like The One Ashford Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does your area include sites such as Ellingham Industrial Estate, near Kingsnorth?
Yes, sites like Ellingham Industrial Estate are within our area, along with the rest of Kingsnorth. Photos and a short description are enough for a first look.
Why has the sealant in our expansion joints split?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
What timescale should we allow for resealing expansion joints?
Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote along with the phasing plan.
Is movement joint sealing guaranteed?
The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

From enquiry to sign-off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. For a building around Kingsnorth, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the 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.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.

- Areas reopen once cured, and the work carries our 12-month guarantee.

What the job involves on each surface
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.
