When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Uneven floors that need grinding or levelling
- Cracks across panels caused by settlement or overload
- A failing floor coating, which is a flooring contractor’s job
If you are not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

How we handle floor joint sealing in Berkhamsted
Before quoting, we look at what the floor is telling us: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. That tells us whether semi-rigid filler or flexible sealant suits each run and the answer can differ from one zone to the next. We work on loading bays, construction joints and saw-cut induced joints, and the failures we are asked to look at most are dock area joints that have failed first and cracked and crumbling joint fill. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Berkhamsted is the same: the right product in a properly prepared joint.
Joints in town car parks and service yards take tyres, de-icing salt and standing water. Resealing before the edges break up is far less disruptive than repairing them later.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Questions about Berkhamsted
Will our site in Berkhamsted have to close for joint sealing?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
Is a hospital such as Hemel Hempstead Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Why is there a gap next to the joint filler?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. It is usually dealt with by topping up.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Is the floor joint work guaranteed?
There is a 12-month guarantee on our workmanship, and we hold public liability insurance.
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 it all comes out first.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep photographs of joints that look like they’re failing
- Keep trucks off new joints until we say they’re ready
- Plan for a top-up on newer floors
- Ask drivers not to drag forks or pallets
Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time if it keeps happening.
A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.
What the job involves on each surface
Saw-cut induced joints
Most of the joints in a warehouse floor are saw cuts. We clear them back to clean concrete and fill them to the depth the product calls for, finishing flush with the slab.
Construction joints
Day joints on busy routes are prone to edge damage. Movement and traffic are both checked before we decide what goes in.
Commercial clients in Berkhamsted
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a town like Berkhamsted, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we’ll fit the work in.

What else we do in Berkhamsted
Floor joint sealing in Berkhamsted: the local picture
Rainfall across the South East, Berkhamsted included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Central London is about 27 miles from Berkhamsted. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Across sites such as Northbridge Road Industrial Estate, which lies north-west of Berkhamsted, floor and movement joints can be sealed in phases so units keep working. Sites like Hemel Hempstead Hospital (to the east of Berkhamsted) carry ambulances, deliveries and visitors’ cars over their road and deck joints. In a school such as St Thomas More Roman Catholic Voluntary Aided Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
