Expansion joint sealing for commercial buildings in Kingsnorth
We have been sealing expansion and movement joints for over 20 years. 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 brickwork movement joints, car park decks and ramps and precast concrete panel joints, and what we are called in for most is water getting into the wall through a failed joint and chipped joint edges on forklift routes. For commercial sealant work in Kingsnorth, you deal with one contact from quote to sign-off, whether it’s one building or several.
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.
A 12-month guarantee applies to all our work in Medway. Should something we installed fail, call 01277 525 020 or use the quote form and we will come back to it.

FAQs: Kingsnorth
Is Kingsnorth off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does the sea air around Kingsnorth change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Why do our movement joints keep failing?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing, rather than replacing like for like.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Are expansion joints and movement joints the same thing?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped, and the sealing method is much the same.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Common problems we fix in Kingsnorth
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
Clients normally get in touch after noticing something like this:
- Weathered movement joint sealant that no longer flexes
- Joints packed with grit and debris
- Leaks through car park deck joints onto the level below
- Sealant peeling off one face of the joint
A campus such as University of Greenwich - Medway (to the south-west of Kingsnorth) has long runs of movement joint in its buildings, decks and paving.
What your quote should include
- The terms of the workmanship guarantee
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
Cost factors for movement joints
There’s no standard rate for sealant work, because every site is different. What we look at:
- Travel to remote or island sites
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
- Any access equipment needed
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 we need to price the job
A few photographs plus some basic facts will normally do. It helps to include:
- The type of building and who uses it
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- Specification clauses that apply
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email us.

Looking after the joints
After handover, these steps help:
- Inspect exposed joints once the cold weather has passed
- Reopen bays and walkways only after the stated cure time
- Keep stones and debris out of open joint lines
- Raise snow-clearing blades over deck joints where possible
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
What the job involves on each surface
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
Where floor joints take the most wear near Kingsnorth
Kingsnorth lies within about 1 mile of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Kingsnorth lies roughly 30 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Hospitals like Medway Maritime Hospital (to the south-west of Kingsnorth) have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools such as The Hundred of Hoo Academy have movement joints in their walls and floors that are easy to overlook.

What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Leaks coming from the membrane rather than the joint seal
- Cracking or settlement that calls for an engineer’s assessment
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
