When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.
Floor joint sealing in Chandler's Cross, done properly
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. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. We work on saw-cut induced joints, loading bays and retail and showroom floors, and the failures we’re asked to look at most are soft sealant dragged out of trafficked joints and chipped and spalling edges along forklift routes.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Mention any aggressive cleaning regime at quote stage
- Remind operators to lift rather than drag
- Keep grit out of unfilled joints in the meantime
- Start with the dock areas, where joints fail soonest
If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. After that, a check before your busiest period keeps small repairs small.
Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas and keeps on top of the rest.

- Untidy open joints in a retail unit
- Joint edges breaking up under truck wheels
- Soft sealant dragged out of trafficked joints

Questions about Chandler's Cross
Do you cover business parks and estates near Chandler's Cross, such as Shakespeare Industrial Estate?
Yes. Our area takes in Chandler's Cross and its surroundings, with estates and business parks such as Shakespeare Industrial Estate included. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Chandler's Cross too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How soon can traffic go back on the floor?
The wait is set by the product’s cure time, and cold floors slow it down. Phasing is planned with that in mind.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you repair broken joint edges?
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.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
