When to call us in Kitts End
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.
Clients normally get in touch after noticing something like this:
- Water dripping through deck or ramp joints
- Expansion joints split through the centre of the bead
- Joints packed with grit and debris
- Previous reseals laid over old sealant
Sites like Potters Bar Community Hospital (to the north-east of Kitts End) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- What site paperwork they can supply
- The named product and why it was chosen
- How joint depth will be controlled
About our expansion joint sealing in Kitts End
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, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. Most enquiries involve expansion joints split through the centre of the bead and layers of sealant in a movement joint, on podiums and floor movement joints, blockwork control joints and brickwork movement joints. Facilities teams, main contractors and managing agents in Kitts End tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a site near Kitts End, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When to bring in a specialist
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Waterproofing layers buried beneath the sealant
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Kitts End can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.

Common questions from Kitts End clients
Is Kitts End too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Wrotham Business Park, near Kitts End?
Yes. We cover Kitts End and the area around it, including industrial estates, business parks and retail parks such as Wrotham Business Park. Photos and a short description are enough for a first look.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
What’s the difference between an expansion joint and a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Why act early in Kitts End
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind and repeated access costs add up. Where it helps, we quote both options. Halls, stores and units around places like Kitts End may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why appoint us
- Old sealant cut out, never sealed over
- Coloured sealants to suit the setting, where available
- Fully insured
- Fixed quotes based on photographs, drawings or a visit
