Your questions answered

Is Hunston too far out for you?

Not at all. Hunston is within our area. 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.

Our building in Hunston is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Can the warehouse stay open while you work?

Normally only the zone we are working in has to close. Traffic returns to each zone once it has cured, then we move to the next.

Do you use semi-rigid filler or flexible sealant on floor joints?

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is the floor joint work guaranteed?

A 12-month guarantee covers the work we do. It covers our workmanship, not later slab movement or damage from impacts.

About our floor joint sealing in Hunston

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. If you have brittle joint filler breaking up and failing joints at loading bays and dock doors, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Hunston it comes down to the same thing: the right product in a properly prepared joint.

Jobs around smaller places like Hunston are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.

Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we will come back to it.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Wide or random cracking that suggests a structural issue
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Slab panels that rock or move under load

If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What we seal

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

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Quoting for work in Hunston

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • Any access equipment needed

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • A wide shot and a close-up of the area
  • Access details, including height
  • Whether an asbestos survey exists
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Check joint lines on busy aisles regularly
  • Photograph any joint that starts to chip
  • Expect fillers on young slabs to need a top-up
  • Remind operators to lift rather than drag

A routine walk of the busiest aisles shows how the joints are holding up. Watch for filler pulling away from an edge, fresh chipping or grit collecting and keep photos so changes are easy to compare.

While the concrete edges are intact, it’s a filling job. After the edges go, repairs come into it, with more downtime and more disruption.

On site: what to expect

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Hunston may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

Retail work is phased around trading. Give us your opening pattern and access windows and the phasing follows.

Semi-rigid joint fillers

Semi-rigid fillers are designed to support joint edges under hard wheels. They tolerate little movement, so they suit joints where most shrinkage has already happened.
