About our expansion joint sealing in Caldecote
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. 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. We work on brickwork movement joints, podiums and floor movement joints and car park decks and ramps, and what we are called in for most is weathered movement joint sealant that no longer flexes and sealant pulling off the joint face.

Halls, schools and small commercial buildings near places like Caldecote have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

FAQs: Caldecote
Is a hospital such as Blakelands Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Caldecote outside your area?
Not at all. Caldecote is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last and we will flag every length affected. Sealing over them leads to early failure.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.

- First the joints are inspected, widths measured and the type of failure noted.
- 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.

When to call us in Caldecote
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. The product has to be suited to the traffic.
It’s worth sending us details if you spot any of the following:
- Layers of sealant in a movement joint
- Spalled or broken joint edges in floors and decks
- Movement joints with split or torn sealant
- Expansion joints filled with dirt and stones
For buildings at a park such as Cromwell Business Park, 0.9 miles north-east of Caldecote, brick and panel movement joints are easy to forget until one leaks.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- The terms of the workmanship guarantee
- Their plan for phasing and protecting the area
- Will CSCS-carded applicators be on site?
Different surfaces, different methods
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.

What affects the price in Caldecote
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
