About our floor joint sealing in Lower Upnor

It isn’t only heavy industry. Shops, showrooms and trade counters have joints that take trolleys, foot traffic and scrubber-driers, and an open, grimy joint line looks poor as well as catching wheels. A flush, well-finished joint tidies the whole floor. If you’re dealing with scruffy, dirty joint lines on a shop or showroom floor and drivers complaining about joints on a route, we can help, whatever the surface. For commercial sealant work in Lower Upnor, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller community and commercial buildings around Lower Upnor have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Joints that move: notes for Lower Upnor

The sea is no more than about 2 miles from Lower Upnor. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Lower Upnor is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.

For an estate such as Medway Maritime Hospital (2.3 miles south of Lower Upnor), the joints in ramps, decks and long building elevations all need attention over time. Campuses like University of Greenwich - Medway (to the south-east of Lower Upnor) mix old and new buildings, with movement joints wherever they meet. Centres like Strood Retail Park, 1.9 miles south-west of Lower Upnor, have mall floors and service decks whose joints carry steady traffic.

Why deal with it now?

While the arrises are intact, filling a joint is straightforward. Left until they break, it needs an edge repair before any filling can start which means more downtime in that zone. Halls, stores and units around places like Lower Upnor may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Level or flatness problems across the floor
  • Spalled arrises, which need an edge repair first
  • Structural cracking in the slab

If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

  • Construction joints
  • Retail and showroom floors
  • Forklift and pallet-truck routes
  • Loading bays
  • Joints along racking aisles
  • Saw-cut induced joints

Maintenance after handover

A few simple habits keep the new joints working:

  • Record damaged joints with a photo and a location
  • Sweep debris out of open joints until they can be filled
  • Expect fillers on young slabs to need a top-up
  • Mention any aggressive cleaning regime at quote stage

Problems inside the 12-month guarantee period are ours to put right. Beyond that, an inspection once or twice a year catches failing joints early.

Every vehicle on a busy aisle hits a damaged joint. Early treatment protects wheels, loads and drivers as much as the floor.

What the job involves on each surface

Loading bays and dock areas

Bays can be treated one or two at a time so deliveries keep moving. Your site hours and access windows set the order.

Retail and showroom floors

Retail joints see trolleys, footfall and scrubber-driers. We pick a filler or sealant to suit and the appearance is part of the brief.
