Lavendon: questions and answers

Do we have to stop operations in Lavendon while the joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Is Lavendon off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.

About our floor joint sealing in Lavendon

We diagnose the floor first rather than guessing at a product: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. That tells us whether semi-rigid filler or flexible sealant suits each run and the answer can differ from one zone to the next. We work on joints along racking aisles, saw-cut induced joints and loading bays, and what we’re called in for most is joint edges breaking up under truck wheels and open saw cuts full of debris. Whether you call it commercial sealant work, mastic application or joint sealing, in Lavendon it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Building owners, agents and FMs in Lavendon

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Why act early in Lavendon

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. One visit to deal with every failing joint makes more sense than several trips to a place like Lavendon. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • Constructionline member for supplier checks
  • 12-month guarantee on workmanship
  • Fully insured, including public liability cover
  • CSCS-carded applicators

How the job changes by surface

Forklift and pallet-truck routes

Joints on busy routes need a fill that sits flush and resists impact. Wheel type and traffic level steer the product choice.

Saw-cut induced joints

Most of the joints in a warehouse floor are saw cuts. Each one is cleaned out and filled to the specified depth, finishing flush with the slab.

Slabs, ramps and loading bays in Lavendon

Central London is about 52 miles from Lavendon. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Lavendon sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Schools such as Lavendon School have movement joints in their walls and floors that are easy to overlook.

When to call us in Lavendon

Oil, laitance, dust and old cleaning chemicals build up inside joints. Without cutting back to sound, clean concrete the new filler can’t stay bonded.

Most enquiries start with something like this:

  • A gap opening alongside old joint filler
  • Joint edges breaking up under truck wheels
  • Dock area joints that have failed first
  • Old filler gone hard, cracked or loose

In and around Lavendon, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Questions to ask before you book

  • The named product and why it was chosen
  • Are they CHAS accredited or on Constructionline?
  • How joint depth will be controlled
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Lavendon need work, visits can be combined. A fixed quote is given before anything starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.

Getting the site ready

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000

Request a quote

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Slab panels that rock or move under load
  • Structural cracking in the slab
  • Damaged or worn floor coatings and screeds

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

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