How we handle expansion joint sealing in Leckford
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors on sites in Leckford. We work on podiums and floor movement joints, brickwork movement joints and cladding panel joints, and what we’re called in for most is rain penetration at brick or block movement joints and chipped joint edges on forklift routes. A specialist sealant contractor works differently from a general builder: in Leckford, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Leckford have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Will our site in Leckford have to close for joint sealing?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.
Is Leckford off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last. A bead on a broken edge soon lets go.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Leckford can form part of a wider programme across Hampshire.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
After the work
For the best life from the joints:
- Keep racking legs and heavy point loads off floor joints
- Clear dirt from joint lines during routine cleaning
- Note which joints were done, when, and with what
- Leave barriers in place until fresh joint sealant has cured
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Leaks coming from the membrane rather than the joint seal
- Damaged metal nosings or cover plates over a joint
- Concrete or masonry repairs along the arrises
If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Expansion joint sealing in Leckford: the local picture
Rainfall across the South East, Leckford included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Central London is about 64 miles from Leckford. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
Hospital campuses such as Andover War Memorial Hospital, 5.6 miles north of Leckford, grow in stages, leaving movement joints wherever new blocks meet old. Schools like Test Valley School often have long brick elevations with movement joints that age quietly.
Leckford is about 5 miles south of Andover, in Hampshire. If you are looking for expansion joint sealing in Leckford, we can help, as we do across Hampshire.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For a building around Leckford, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- 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.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Tell us which areas need to stay in use
- Make sure the joints can be reached

Different surfaces, different methods
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces, with primer where specified.
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.
Why deal with it now?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we will say so before quoting. Around Leckford, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
