Slabs, ramps and loading bays in Rowner
Rowner sits close to the coast, within about 2 miles. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Rainfall across the South East, Rowner included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
A campus such as University of Portsmouth - North Zone (to the south-east of Rowner) has long runs of movement joint in its buildings, decks and paving. Across sites such as Speedfields Retail Park, 1 mile north-west of Rowner, floor and movement joints can be sealed in phases so units keep working.
Rowner is about 2 miles north-west of Gosport, in Hampshire. Any commercial site in Rowner is covered, for single jobs and planned programmes alike. Our Hampshire coverage takes in 723 places, from busy centres to rural villages.

Expansion joint sealing in Rowner
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 is tooled so it grips the two faces alone. We work on brickwork movement joints, podiums and floor movement joints and car park decks and ramps, and what we are called in for most is joints where the bead has lost adhesion and brittle, chalky sealant on external joints. Whoever orders the work in Rowner, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around Rowner, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Cost factors for movement joints
We price every job individually. The things that drive the figure:
- How much existing material needs removing
- Whether the work must be split into stages
- Which sealant the job calls for
- Distance, for remote addresses
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- Clear photos of the problem areas
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
- Anything awkward about access or site hours
To get a fixed quote, call the office on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. You can also send details through our quote form.

Questions we’re asked in Rowner
Is Brockhurst Gate Retail Park, near Rowner, within your area?
Yes. Estates, retail parks and business parks around Rowner, Brockhurst Gate Retail Park among them, are all within reach. A few photographs and the unit address let us price the work.
Our building in Rowner is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
What sealant do you use in movement joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane.
Do you guarantee expansion joint work?
The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.
What happens if it rains on the day?
Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work so external dates keep some flexibility.
When to call us in Rowner
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.
Look out for the following:
- Expansion joints split through the centre of the bead
- Water dripping through deck or ramp joints
- New sealant over old, now failing
- Debris jammed in movement joints
For a school such as Bridgemary School, playground and building joints can be done in the holidays.

- Their plan for phasing and protecting the area
- Their approach to joint depth and backing

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. What matters most for a job in Rowner is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid 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
- Warn occupants and staff about the work
- Send your site hours and access windows
- Tell us which areas need to stay in use

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Leaks coming from the membrane rather than the joint seal
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
