Expansion joint sealing in Chitty
Buildings and slabs are never completely still: 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. We work on brickwork movement joints, cladding panel joints and blockwork control joints, and the usual reasons a site gets in touch are new sealant over old, now failing and debris jammed in movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chitty is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Jobs around smaller places like Chitty are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Chitty
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
Things that usually lead to an enquiry:
- Expansion joints split through the centre of the bead
- Leaks through car park deck joints onto the level below
- Previous reseals laid over old sealant
- Spalled or broken joint edges in floors and decks
Schools like Chislet Church of England Primary School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- Can the work be phased to keep areas open?
- The named product and why it was chosen
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?

What the job involves on each surface
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
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, and tell you if edges need repairing first.
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Chitty, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings

Questions about Chitty
Is Chitty too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Will you take on work at estates like Chislet Business Park, close to Chitty?
Yes. Our area takes in Chitty and its surroundings, with estates and business parks such as Chislet Business Park included. Photos and a short description are enough for a first look.
What causes movement joint sealant to fail?
The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are expansion joints and movement joints the same thing?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.
Floors, slabs and movement joints in Chitty
With the shore within about 3 miles, Chitty counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Chitty sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
Another example is Canterbury Industrial Park, 1.9 miles south-west of Chitty, where floors and yards would be done in stages around the occupiers. Business parks such as Chislet Business Park (1.7 miles south-west of Chitty) have car parks, paved areas and long brick and panel elevations, all with movement joints.
Chitty is about 4 miles south-east of Herne Bay, in Kent. Across the CT3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Location, for remote and island sites
- Access and working height
- The site’s rules and procedures
- How much existing material needs removing
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- The type of building and who uses it
- The postcode of the building
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email drawings and photos.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Leaks coming from the membrane rather than the joint seal
- Joints too narrow for the movement, which need redesigning by the engineer
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
What we seal
- Precast concrete panel joints
- Brickwork movement joints
- Cladding panel joints
- Car park decks and ramps
- Blockwork control joints
- Podiums and floor movement joints
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
