Expansion joint sealing in Portsmouth: how it works
We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on car park decks and ramps, cladding panel joints and brickwork movement joints, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and chipped joint edges on forklift routes.
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it.
- 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.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What you’ll pay

Floors, slabs and movement joints across Portsmouth
Across Portsmouth, warehouse floors, loading bays and car parks in places such as Southsea, Milton and Landport carry joints that take constant loads. Each joint needs a product suited to what runs over it and how much it moves.
We work across Greater London and the South East counties, and every job in Portsmouth starts with access, parking and site rules. On the coastal side of Portsmouth, sea-facing elevations typically show failed joints first, so they’re worth inspecting more often.
Portsmouth: At a retail site such as Victory Retail Park (0.5 miles west of Portsmouth), joints in car parks, service yards and sales floors carry cars, cages and trolleys every day. For estates staff at a university like University of Portsmouth, 1.1 miles to the south of Portsmouth, building and paving joints are part of the planned maintenance list.
What affects the price in Portsmouth
These are the things that shape the price:
- How much there is to seal
- The product specified
- Site requirements such as inductions and permits
- Joint width, depth and condition
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Your programme or deadline

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
What happens if it’s left?
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall. Acting at the first split keeps the cost down.
What your quote should include
- Proof of insurance
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
- How the joint faces will be prepared and primed
Signs you need expansion joint sealing
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
Common reasons buildings call us in:
- Layers of sealant in a movement joint
- Sealant peeling off one face of the joint
- Arrises breaking up along floor joints
- Car park joints leaking onto vehicles below
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Common questions from Portsmouth clients
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What timescale should we allow for resealing expansion joints?
It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing and phased work can stretch that to suit your site. We will confirm when each area can be used again.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.
