Expansion joint sealing for commercial buildings in Conyer
Buildings and slabs are never completely still: 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, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Conyer. Site teams most often ask us about sealant pulling off the joint face and layers of sealant in a movement joint, on car park decks and ramps, podiums and floor movement joints and brickwork movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Conyer, that means joint design, primers and backing rod as standard.
In and around smaller places like Conyer, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Slabs, ramps and loading bays in Conyer
The sea is no more than about 1 mile from Conyer. 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. Conyer sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.
Once a joint near Conyer opens up, grit and water get in and the edges start to break.
Conyer is about 4 miles east of Sittingbourne, in Kent. Commercial clients in Conyer use us for work on movement joints, as part of our coverage of Kent. Conyer is one of 931 places in Kent on our list for movement joints. Sites around London have their own page, about 41 miles away.

Common problems we fix in Conyer
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
Site and facilities staff are often the first to spot these:
- Joints packed with grit and debris
- Arrises breaking up along floor joints
- Water getting into the wall through a failed joint
- Layers of sealant in a movement joint
For floors and slabs around Conyer, the product is chosen for the traffic and the movement at each joint.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- How long is the guarantee, and what does it include?
- Whether their applicators hold CSCS cards
- Their public liability cover
Leave it or put it right?
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Older rural buildings around Conyer move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

What else we do in Conyer
Questions we’re asked in Conyer
Is Conyer too small for you to travel to?
No. Places such as Conyer are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can being near the sea in Conyer affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Is colour matching possible?
Often, 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 much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
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.
Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Conyer. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Conyer need work, visits can be combined. You will have a fixed quote before work starts.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How the job changes 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.
Brickwork and blockwork joints
Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.
