Expansion joint sealing in Leagreen, done properly
We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on cladding panel joints, brickwork movement joints and podiums and floor movement joints, and what we are called in for most is joints packed with grit and debris and sealant pulling off the joint face. Most enquiries from Leagreen start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Halls, schools and small commercial buildings near places like Leagreen have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Expansion joint sealing around Leagreen: what changes locally
Leagreen sits close to the coast, within about 1 mile. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Rainfall across the South East, Leagreen included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
If you manage units on an estate such as Gore Road Industrial Estate, which lies west of Leagreen, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. For a school such as Hordle CofE (VA) Primary School, playground and building joints can be done in the holidays.
Leagreen is about 3 miles west of Lymington, in Hampshire. We cover commercial sites throughout Leagreen, for single jobs and planned programmes alike. We work across 723 places in Hampshire. Sites around Southampton have their own page, about 15 miles away.

Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Treat a small split as a warning, not a cosmetic issue
- Clear dirt from joint lines during routine cleaning
- Brief car park operatives to protect joint lines during winter clearance
- Leave barriers in place until fresh joint sealant has cured
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall. A sound seal keeps the joint working.
Questions about Leagreen
Is hospital work, at somewhere like Lymington New Forest Hospital, something you do?
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 Leagreen outside your area?
Not at all. Leagreen is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you reseal car park expansion joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed and broken edges are flagged before sealing.
What if the joint edges are damaged?
A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.
Do you use silicone or polyurethane in movement joints?
The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
Do you guarantee expansion joint work?
The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.
When to call us in Leagreen
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.
Things that normally lead to an enquiry:
- Expansion joints filled with dirt and stones
- Previous reseals laid over old sealant
- Arrises breaking up along floor joints
- Brittle, chalky sealant on external joints
Hospitals like Lymington New Forest Hospital, 3.5 miles north-east of Leagreen, have multi-storey or surface car parks whose joints carry vehicles round the clock.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
Cost factors for movement joints
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
- How much there is to seal
- Location, for remote and island sites
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.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- The product your specification calls for
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- Access details, including height
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email us to discuss it first.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.
Surfaces we seal
- Car park decks and ramps
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
- Cladding panel joints
- Precast concrete panel joints
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Leagreen, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Tell us your opening times and when work is allowed
- Move anything stored against the joints
