Floor joint sealing in Whitchurch-on-Thames

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Why act early in Whitchurch-on-Thames

Broken joints shake trucks, stock and operators alike. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. Older rural buildings around Whitchurch-on-Thames move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.

After the work

After handover, these steps help:

  • Keep trucks off new joints until we say they’re ready
  • Keep photos of joints that look like they’re failing
  • Put loading bays at the top of the list
  • Ask drivers not to drag forks or pallets

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. In a busy building, barriers keep early traffic away.

Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas and keeps on top of the rest.

Common questions from Whitchurch-on-Thames clients

Will our site in Whitchurch-on-Thames have to close for joint sealing?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Is Whitchurch-on-Thames too small for you to travel to?

Not at all. Whitchurch-on-Thames is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

What happens if the joint edges are damaged?

We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.

What happens if old sealant might contain asbestos?

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. Removing asbestos is a job for asbestos specialists, not us.

Slabs, ramps and loading bays in Whitchurch-on-Thames

Central London is about 43 miles from Whitchurch-on-Thames. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Whitchurch-on-Thames sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

In a school such as Whitchurch Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Sites like Battle Hospital, 4.4 miles south-east of Whitchurch-on-Thames, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Loading bays and dock areas

Bays can be treated one or two at a time so goods in and out carry on. Tell us your site hours and access windows and we will plan around them.

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filling them early keeps them tidy and protects the edges.
