About our expansion joint sealing in Coxheath
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on podiums and floor movement joints, precast concrete panel joints and car park decks and ramps, and what we’re called in for most is layers of sealant in a movement joint and water getting into the wall through a failed joint. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Coxheath it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places the size of Coxheath, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in Coxheath, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Point out any areas we must not close
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
When to call us in Coxheath
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. Resealing like for like often fails the same way.
Things that usually lead to an enquiry:
- Previous reseals laid over old sealant
- Damp inside where a wall movement joint has failed
- Hardened, cracked sealant on exposed facades
- Expansion joints filled with dirt and stones
Phasing is what makes joint work possible on busy sites such as Orchard Industrial Estate (2.7 miles east of Coxheath): one bay, aisle or car park row at a time.
What your quote should include
- Their public liability cover
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Waterproofing layers buried beneath the sealant
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.
Joints and surfaces we work on
- Podiums and floor movement joints

When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Leave it or put it right?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. For buildings in places like Coxheath, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
