Cannon's Green sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.

If you manage units on an estate such as Hallsford Bridge Industrial Estate, which lies south of Cannon's Green, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

In and around smaller places like Cannon's Green, 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
- Proprietary pre-formed expansion joint systems
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
What we seal
- Blockwork control joints
- Podiums and floor movement joints
- Brickwork movement joints
- Precast concrete panel joints
- Cladding panel joints
- Car park decks and ramps
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Plan racking layouts so feet don’t land on a joint
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Brief car park operatives to protect joint lines during winter clearance
- Record the sealant used and the date in the O&M file
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Resealing early limits the damage.
Different surfaces, different methods
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.
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.
What we’re called out for in Cannon's Green
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
If one of these sounds familiar, it’s time for a closer look:
- Hardened, cracked sealant on exposed facades
- Debris jammed in movement joints
- Expansion joints split through the centre of the bead
- Chipped joint edges on forklift routes
Schools like The Ongar Academy often have long brick elevations with movement joints that age quietly.

Questions we’re asked in Cannon's Green
Must our site in Cannon's Green stop work while the joints are done?
Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.
Is Cannon's Green too far out for you?
No. Places such as Cannon's Green are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What do you charge?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email the details over with a description of the work.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Cannon's Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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.
Getting the site ready
- Flag any permit to work we’ll need
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
