About our expansion joint sealing in Landport
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors on sites in Landport. Most enquiries involve arrises breaking up along floor joints and joints where the bead has lost adhesion, across blockwork control joints, cladding panel joints and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: in Landport, that means joint design, primers and backing rod as standard.
Rural business units around smaller places such as Landport often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Cost factors for movement joints
Quotes vary with the job. Expect it to depend on:
- Backing rod, priming and other preparation
- Working within restricted access windows
- How much there is to seal
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What we need to price the job
It doesn’t need to be a full survey. A few details are enough to get going:
- The type of building and who uses it
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Any specification or named product

Surface by surface
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Leaks coming from the membrane rather than the joint seal
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Proprietary pre-formed expansion joint systems
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Questions about Landport
Would you work within a site like St James Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Does the sea air around Landport change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What timescale should we allow for resealing expansion joints?
The metres of joint, the access and the amount of removal decide it. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.
Do you guarantee expansion joint work?
Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
How do we ask for a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Expansion joint sealing around Landport: points for this area
Landport sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Landport is about 65 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.
Hospital campuses such as St James Hospital, 1.9 miles to the east of Landport, grow in stages, leaving movement joints wherever new blocks meet old. For a centre such as Tricorn Centre, under half a mile west of Landport, the service yard and car park joints typically need attention first. University campuses such as University of Portsmouth - North Zone, 0.6 miles to the south-west of Landport, have car parks, paved walkways and building elevations with movement joints.
Landport is about 1 mile south-west of Portsmouth, in Portsmouth. Across the PO1 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Landport is one of 19 places in Portsmouth on our list.

Local landmarks in Landport
Around Landport, our work takes us to commercial buildings near The Painters Arms, St Edmund's Catholic School and Alexandra Park. Landport has its own railway station: Portsmouth & Southsea station.

Open spaces near Landport include Milton Locks and Portsdown Hill.
Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we will plan around it. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. What matters most for a job in Landport is a clear list of what needs doing, so send photos of each area. You’ll then get a fixed price for the work.
- 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 tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Point out parking and an unloading spot
- Warn occupants and staff about the work
