Expansion joint sealing in New Hythe, done properly
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors on sites in New Hythe. We work on car park decks and ramps, cladding panel joints and podiums and floor movement joints, and what we’re called in for most is torn sealant in brick or block movement joints and expansion joints filled with dirt and stones. One point of contact handles commercial sealant work in New Hythe from the first photos to the final walk-round, for single jobs and planned programmes alike.
Smaller community and commercial buildings around New Hythe have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Waterproofing layers buried beneath the sealant
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Proprietary pre-formed expansion joint systems
If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer.
Joints and surfaces we work on
- Brickwork movement joints
- Blockwork control joints
- Car park decks and ramps
- Precast concrete panel joints
- Cladding panel joints
- Podiums and floor movement joints
Surface 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 flagging broken arrises before sealing.
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces priming where the maker calls for it.
On site: what to expect
On arrival, 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, with the work itself typically taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. For work around New Hythe, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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 tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in
- Move anything stored against the joints

Your questions answered
Do you cover business parks and estates near New Hythe, such as New Hythe Business Park?
Yes. Our area takes in New Hythe and its surroundings, with estates and business parks such as New Hythe Business Park included. A few photographs and the unit address let us price the work.
Can you work on a hospital site such as Maidstone Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
What will the job cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or use the quote form with a description of the work.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Keeping joints clear of debris helps them last.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What if the joint edges are damaged?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- 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
- Treat a small split as a warning, not a cosmetic issue
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
What happens if it’s left?
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. For buildings around smaller places like New Hythe, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
