How we handle expansion joint sealing in Langstone
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 and the bead bonds to the sides, never the back. We work on precast concrete panel joints, podiums and floor movement joints and blockwork control joints, and what we are called in for most is spalled or broken joint edges in floors and decks and joints packed with grit and debris. Searching for sealant specialists in Langstone? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Smaller community and commercial buildings around Langstone have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When to call us in Langstone
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Common reasons buildings call us in:
- New sealant over old, now failing
- Joints where the bead has lost adhesion
- Expansion joints filled with dirt and stones
- Hardened, cracked sealant on exposed facades
A campus such as University of Portsmouth - Langstone Campus, 4 miles to the south-west of Langstone, has long runs of movement joint in its buildings, decks and paving.
What your quote should include
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- How the joint faces will be prepared and primed
Owners, agents and contractors
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Langstone can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space

Advice
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Joint width, depth and condition
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- Access and working height
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.
What to include in your enquiry
However big the job, the same details help:
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- Your programme or deadline
- The product your specification calls for
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Slabs, ramps and loading bays in Langstone
Langstone is within about 1 mile of the coast. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. Less than 3 miles from Langstone there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Schools like Bosmere Junior School often have long brick elevations with movement joints that age quietly. Retail parks like Solent Retail Park (to the north of Langstone) have long runs of car park and yard joints taking daily traffic.

Keeping the joints sound
To get the most from the new sealant:
- Include every elevation and deck joint in periodic inspections
- Look over external and deck joints after a hard winter
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Avoid parking heavy plant or pallets on joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can ring 01277 525 020 or email us and send a picture.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Cracking or settlement that calls for an engineer’s assessment
- Concrete or masonry repairs along the arrises
- Joints too narrow for the movement, which need redesigning by the engineer
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Your questions answered
Does a coastal location like Langstone affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is a smaller place like Langstone outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
What will the job cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
How do I request a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you use silicone or polyurethane in movement joints?
Movement capability matters most as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
