How a job runs
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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Cooper's Green can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- 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.
What we need from you
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work

Advice
Floor joint sealing for commercial buildings in Cooper's Green
We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant, area by area where it needs to be. If you have a gap opening alongside old joint filler and joint edges breaking up under truck wheels, we can put it right. For commercial sealant work in Cooper's Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a site near Cooper's Green, measurements and photos up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

How the quote is worked out
We price every job individually. The main factors are:
- Joint width, depth and condition
- Whether the work must be split into stages
- Location, for remote and island sites
- Access and working height
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
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
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email drawings and photos.
Cooper's Green: questions and answers
Would you work within a site like One Hatfield Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Can you work at a site such as Oldings Corner Retail Park, by Cooper's Green?
Yes, sites like Oldings Corner Retail Park are within our area, along with the rest of Cooper's Green. Send details of the unit and the work through our quote form for a quick quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Should floor joints be filled or sealed?
We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler, and movement joints or perimeters need something flexible. You will see the choice for each area in the quote.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you fill joints where the arrises have spalled?
Edge condition is recorded when we look at the floor. Damaged edges are flagged up front, so nothing is filled that won’t hold.
Surface by surface
Flexible floor sealants
Polyurethane floor sealants are available in a range of colours so ask if the colour matters.
Isolation joints at walls and columns
Joints at walls and columns are often missed when floors are sealed, and they collect dust and debris. We include them in the survey.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Cooper's Green can sit alongside others in a wider programme.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

When to call us in Cooper's Green
Concrete slabs shrink as they dry out, and saw-cut joints give that shrinkage a planned place to crack. Each panel pulls back as it shrinks and the joints open up so a filler put in early may separate along one side.
Clients normally get in touch after noticing something like this:
- Soft sealant dragged out of trafficked joints
- Saw-cut joints left open and packed with grit
- Scruffy, dirty joint lines on a shop or showroom floor
- A gap opening alongside old joint filler
Another example is Sandridge Gate Business Centre, 2.2 miles to the west of Cooper's Green, where floors and yards would be done in stages around the occupiers.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Will RAMS and insurance details be available?
- How the existing material will be dealt with
- Will CSCS-carded applicators be on site?
