Expansion joint sealing for commercial buildings in Charing

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing. If you have sealant peeling off one face of the joint and weathered movement joint sealant that no longer flexes, we can help, on precast concrete panel joints, blockwork control joints and podiums and floor movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Charing, that means joint design, primers and backing rod as standard.

Work in a smaller place like Charing is usually one building at a time, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Different surfaces, different methods

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Concrete or masonry repairs along the arrises

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

Where we work in Charing

  • Podiums and floor movement joints
  • Precast concrete panel joints
  • Blockwork control joints
  • Brickwork movement joints
  • Cladding panel joints
  • Car park decks and ramps

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Several jobs near Charing can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
  • Point out parking and an unloading spot

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Why deal with it now?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Cost factors for movement joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The site’s rules and procedures
  • Working within restricted access windows
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • Specification clauses that apply
  • What the building is and how it’s used
  • The asbestos register, for older buildings

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or send details through our quote form with what you know.

Common questions from Charing clients

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

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

Is a smaller place like Charing outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can a joint be sealed if the edges are broken?

Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
