What sets the cost
Quotes vary with the job. It mainly depends on:
- Any access equipment needed
- Location, for remote and island sites
- Joint width, depth and condition
- Whether old sealant has to be cut out first
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- The product your specification calls for
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- Your programme or deadline
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Common questions from Horns Mill clients
Do you cover business parks and estates near Horns Mill, such as Mimram Road Industrial Estate?
Yes. Estates, retail parks and business parks around Horns Mill, Mimram Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Is a hospital such as Hertford County Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
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. A top-up normally puts it right.
What information helps you price floor joint sealing?
A rough joint length, a few photographs and a site plan are normally enough for a quick quote. We can visit where that helps, and you can call 01277 525 020 or email drawings and photos to arrange it.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Do you guarantee industrial floor joints?
A 12-month guarantee covers the work we do. It applies to our workmanship rather than structural movement or accidental damage.

What else we do in Horns Mill
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Leave it or put it right?
Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. Around Horns Mill, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

After the work
Regular inspection catches problems early. In particular:
- Check joint lines on busy aisles regularly
- Clear packed debris from open joints regularly
- Let us know what the floor is cleaned with
- Stop forks and pallets being dragged across joints
Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.
Grit in an open joint does damage every time a wheel crosses it. Getting it filled stops the damage before it becomes a repair.
Do you need floor joint sealing in Horns Mill?
Concrete slabs shrink as they dry out, and saw-cut joints give that shrinkage a planned place to crack. As the panels contract, the joints widen, and a filler placed early can part company with one face.
It’s worth sending us details if you spot any of the following:
- Open saw cuts full of debris
- Drivers complaining about joints on a route
- Chipped and spalling edges along forklift routes
- Dock area joints that have failed first
For a school such as Morgans Primary School & Nursery, playground and building joints can be done in the holidays.
Before you book anyone
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
