About expansion joint sealing in Medway
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on brickwork movement joints, blockwork control joints and car park decks and ramps, and what we’re called in for most is movement joints with split or torn sealant and brittle, chalky sealant on external joints.
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What you will pay

Estates, car parks and floors in Medway
Movement joints in brick, cladding panels and concrete appear on buildings all over Medway, from schools to offices and car parks. A failed joint lets in water and debris, and the edges spall soon after.
London and the South East are among the drier parts of the UK, but external sealing in Medway still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. On the coastal side of Medway, sea-facing elevations normally show failed joints first.
Gillingham: For a centre such as Parkwood Shopping Centre, 1.8 miles south-east of Gillingham, the service yard and car park joints typically need attention first. Campuses like University of Greenwich - Medway (to the north-west of Gillingham) mix old and new buildings, with movement joints wherever they meet.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Joints too narrow for the movement, which need redesigning by the engineer
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Owners, agents and contractors
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Medway can form part of a wider programme.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep scrapers and ploughs from dragging across joint sealant
- Look over external and deck joints after a hard winter
- Leave barriers in place until fresh joint sealant has cured
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. Tell us what has to stay open and we will plan around it.

Questions we’re asked in Medway
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How long does movement joint sealing take?
Expect anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Why has the sealant in our expansion joints split?
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 so the same failure isn’t repeated.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is movement joint sealing guaranteed?
A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Regular sweeping and inspection help the joints last.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
