Floor joint sealing in Cosham: the local picture
The sea is no more than about 1 mile from Cosham. 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. At least three named trading, business or retail sites lie within about 3 miles of Cosham. Their warehouses, yards and car parks are exactly where joints take the most punishment.
A campus such as University of Portsmouth - Langstone Campus, 3.4 miles to the south of Cosham, has long runs of movement joint in its buildings, decks and paving. Hospital campuses such as Queen Alexandra Hospital, 0.6 miles north of Cosham, grow in stages, leaving movement joints wherever new blocks meet old. Another example is Limberline Spur Industrial Estate (0.7 miles south of Cosham), where floors and yards would be done in stages around the occupiers.
Cosham is about 2 miles south-west of Purbrook, in Portsmouth. Anywhere in PO6, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Portsmouth coverage takes in 19 places.

How we handle floor joint sealing in Cosham
For sites in Cosham and across Portsmouth, the process is short: send details, get a fixed quote, we seal, and the work is guaranteed. A rough length of joint, photographs of the worst areas and a site plan let us give a quick quote, or we can arrange a site visit. We work on retail and showroom floors, forklift and pallet-truck routes and loading bays, and what we are called in for most is a gap opening alongside old joint filler and open saw cuts full of debris. A single leaking joint is often how a building in Cosham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Cosham, most floor and movement joint jobs are single buildings or yards. Getting widths, depths and traffic details up front means one visit, not two.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

FAQs: Cosham
Does your area include sites such as Oak Park Industrial Estate, near Cosham?
Yes. Our area takes in Cosham and its surroundings, with estates and business parks such as Oak Park Industrial Estate included. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Does the sea air around Cosham 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. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
What happens if the joint edges are damaged?
We check the edges as part of the survey. Where they have broken away, we will tell you before quoting the filling so the filling isn’t wasted.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Why act early in Cosham
Painting or coating straight over joints rarely lasts. Joints need their own treatment, whether or not the floor is coated. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
- Wide or random cracking that suggests a structural issue
- Damaged or worn floor coatings and screeds
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on

Surface by surface
Forklift and pallet-truck routes
Truck routes take traffic all day and the joints on them break down first. Semi-rigid fillers are widely used on these routes to hold the edges up.
Semi-rigid joint fillers
If a joint is still opening, a semi-rigid filler may part from one face. A later top-up normally puts that right, and we’ll explain it when we quote.
On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Several jobs near Cosham can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- Each phase reopens when the product is ready for wheels, then we start the next.
Preparing the site
- Tell staff and tenants when we will be in
- Point out any areas we must not close
- Share the asbestos register for older buildings
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover
A few simple habits keep the new joints working:
- Keep trucks off new joints until we say they’re ready
- Record damaged joints with a photo and a location
- Stop forks and pallets being dragged across joints
- Mention any aggressive cleaning regime at quote stage
Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it.
Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas and keeps on top of the rest.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Travel to remote or island sites
- The size and state of each joint
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- Any dates the work must fit around
- How the joints are reached, and at what height
- Clear photos of the problem areas
- What the building is and how it’s used
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.
