Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Make joint checks part of your floor inspections
  • Sweep debris out of open joints until they can be filled
  • Keep trucks off new joints until we say they’re ready
  • Plan for a top-up on newer floors

A routine walk of the busiest aisles shows how the joints are holding up. Look for separation down one side, new chips in the arris and debris gathering and keep photographs so changes are easy to compare.

Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

How we handle floor joint sealing in Longcot

Most industrial slabs are divided into panels by saw-cut joints and construction joints, and each joint line is a weak edge that wheels run over all day. Our job is to put the right filler or sealant into them for the loads and the movement they see so the edges are held up and debris can’t pack in. The enquiries we see most involve brittle joint filler breaking up and dock area joints that have failed first, on saw-cut induced joints, joints along racking aisles and retail and showroom floors. Facilities teams, main contractors and managing agents in Longcot tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site near Longcot, measurements and photographs up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a day or more, depending on the metres of joint and how many zones the floor is split into. Rural sites near Longcot 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. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

Where floor joints take the most wear near Longcot

Longcot has two named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Longcot sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Phasing is what makes joint work possible on busy sites such as Shrivenham Hundred Business Park (1.6 miles west of Longcot): one bay, aisle or car park row at a time. A healthcare site such as Faringdon Day Hospital, 2.9 miles to the north of Longcot, depends on car parks, ramps and service yards whose joints take traffic all day. Business parks such as Faringdon Business Park (to the north of Longcot) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Longcot is in Oxfordshire. Our applicators travel to Longcot for work on floor joints, handled exactly as we handle every other area. Across Oxfordshire, 423 places are covered, Longcot among them. For work in that direction, see our Oxford page, about 19 miles away.

What affects the price in Longcot

We price every job individually. The main factors are:

  • The size and state of each joint
  • How much there is to seal
  • Site requirements such as inductions and permits
  • How accessible the joints are

Pricing floor joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

What to include in your enquiry

We can often quote from photographs and a few details. It helps to include:

  • When you need the work done
  • Specification clauses that apply
  • Access details, including height
  • Approximate linear metres or a joint schedule

We quote a fixed sum against the scope you give us, 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.

FAQs: Longcot

Will you take on work at estates like Faringdon Business Park, close to Longcot?

Yes. Estates, retail parks and business parks around Longcot, Faringdon Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as Faringdon Day Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is it normal for joint filler to separate?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Different surfaces, different methods

Semi-rigid joint fillers

If a joint is still opening, a semi-rigid filler may part from one face. A later top-up usually puts that right, and we will explain it when we quote.

Isolation joints at walls and columns

Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We record them with the rest of the floor joints.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Broken concrete either side of the joint
  • Uneven floors that need grinding or levelling
  • A failing floor coating, which is a flooring contractor’s job

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

Joints and surfaces we work on

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

What happens if it’s left?

Dirt and spillage gather in open joints, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. Older rural buildings around Longcot move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
