Surface by surface
Construction joints
Day joints on busy routes are prone to edge damage. We look at how much they are moving before choosing the treatment.
Isolation joints at walls and columns
We plan column and wall joints around racking and fixed plant.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Plan for a top-up on newer floors
- Keep grit out of unfilled joints in the meantime
- Photograph any joint that starts to chip
- Make joint checks part of your floor inspections
Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time if it keeps happening.
Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it, with more downtime and more disruption.
Walsworth: questions and answers
Can you work on a hospital site such as Pinehill Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Walsworth outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Should floor joints be filled or sealed?
The answer comes from the traffic and the joint’s movement. Trafficked joints on truck routes usually need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Worn screed or surface finishes
- A floor that is out of level for the racking or trucks
- A floor that rocks at the joints, which needs a structural fix
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Leave it or put it right?
An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start, with longer closures to match. For buildings in places like Walsworth, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- Products installed to the manufacturer’s instructions

Where floor joints take the most wear near Walsworth
At about 32 miles from central London, Walsworth is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Walsworth sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.
Sites like Pinehill Hospital (to the south-west of Walsworth) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Retail parks like Letchworth Gateway Retail Park (2.6 miles north-east of Walsworth) have long runs of car park and yard joints taking daily traffic. Schools such as Highover Junior Mixed and Infant School have movement joints in their walls and floors that are easy to overlook.

The work itself usually takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need, and we clear our waste as we work. If neighbouring businesses or buildings around Walsworth need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We agree the traffic routes and phasing with your site team.
- Any joints with broken edges are flagged before work starts.
