Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Photograph any joint that starts to chip
  • Make joint checks part of your floor inspections
  • Mention any aggressive cleaning regime at quote stage
  • Expect fillers on young slabs to need a top-up

Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.

Every day an open joint stays full of grit, the edges take more punishment. Filling it ends that cycle while it is still a straightforward job.

Questions we’re asked in The Valley

Does a site in The Valley have to shut while its joints are sealed?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Is The Valley off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship, and we hold public liability insurance.

Do your applicators hold CSCS cards?

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

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Why it’s worth doing now in The Valley

Broken joints shake trucks, stock and operators alike. That means extra wear on wheels and a rougher ride for staff, adding costs nobody plans for. A properly filled joint smooths the route. For buildings around smaller places like The Valley, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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.

Quoting for work in The Valley

We price every job individually. The main factors are:

  • Phasing around occupants
  • The size and state of each joint
  • Access and working height
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • When you need the work done
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • What the building is and how it’s used

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Joints that move: notes for The Valley

Rainfall across the South East, The Valley included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. The Valley lies roughly 42 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Around The Valley, open joints collect water and debris, and the arrises are the next to go. For floors and slabs around The Valley, the product is chosen for the traffic and the movement at each joint.

Advice

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Broken concrete either side of the joint
  • A failing floor coating, which is a flooring contractor’s job
  • Wide or random cracking that suggests a structural issue

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Surfaces we seal

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