Our floor joint sealing service in Portsmouth
We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. Site teams most often ask us about soft sealant dragged out of trafficked joints and joint fill separating from the concrete, across construction joints, forklift and pallet-truck routes and saw-cut induced joints.
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking a day for smaller units, with bigger warehouse floors programmed over several visits.
- We walk the floor and mark up joint widths, edge damage and traffic routes.
- You receive a fixed quote showing products and phasing.
- Each joint is cut or routed back to clean, sound concrete.
- Dust is vacuumed out and primer applied where specified.
- Filler or sealant is placed to depth and finished flush.
- Zones reopen once cured and the work moves on.

Floors, slabs and movement joints across Portsmouth
Sites across Portsmouth rarely stop for joint work, so we phase it bay by bay, aisle by aisle or deck by deck.
Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover Portsmouth along with the rest of the region. Coastal places in Portsmouth often have hotels, guest houses and holiday accommodation with busy seasons, so work is often best planned for quieter months.
Portsmouth: Across sites such as Copnor Bridge Business Centre, 0.6 miles east of Portsmouth, floor and movement joints can be sealed in phases so units keep working. Retail parks like Victory Retail Park, 0.5 miles to the west of Portsmouth, have long runs of car park and yard joints taking daily traffic.
Common problems we fix in Portsmouth
A slab keeps shrinking for a long time after it is cast, and the saw cuts are there so it cracks in straight, controlled lines. Each panel pulls back as it shrinks and the joints open up so a filler put in early may separate along one side.
Clients usually get in touch after noticing something like this:
- Filler that has parted from one face
- Dock area joints that have failed first
- Sealant pulled out along a truck route
- Old filler gone hard, cracked or loose
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Travel to remote or island sites
- How much there is to seal
- Whether the work must be split into stages
- How accessible the joints are
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- The postcode of the building
- Asbestos survey details if the building is older
To get a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Unstable slabs moving under traffic
- Spalled arrises, which need an edge repair first
- Wide or random cracking that suggests a structural issue
Why deal with it now?
Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run.
What your quote should include
- Will CSCS-carded applicators be on site?
- Their plan for phasing and protecting the area
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?
Questions we’re asked in Portsmouth
Will we need to close the floor?
In most cases, just the area being treated is coned off. Traffic returns to each zone once it has cured, then we move to the next.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you fill joints where the arrises have spalled?
We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.
Why is there a gap next to the joint filler?
Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. It is normally dealt with by topping up.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long does a typical visit take?
It depends on the scope, but the work usually takes a day or more, depending on the metres of joint and how many zones the floor is split into. Larger or phased jobs take longer, and we will give you a timescale with the quote.
