About our expansion joint sealing in Dane Hill

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Dane Hill. Most enquiries involve car park joints leaking onto vehicles below and rain penetration at brick or block movement joints, on precast concrete panel joints, cladding panel joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: on jobs in Dane Hill, preparation and product choice get the time they need.

In and around smaller places like Dane Hill, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Work for main contractors and building owners

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Warehouse floors and decks around Dane Hill

At about 61 miles from central London, Dane Hill is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Dane Hill is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Estates like Hatch End Old Industrial Estate (1.8 miles south of Dane Hill) combine warehouse slabs, yards and loading bays, all with joints under wheels. In and around Dane Hill, the right filler or sealant for each joint depends on the traffic and the movement it takes.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • A joint that has to be widened or re-detailed before it can work
  • Damaged metal nosings or cover plates over a joint
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

Looking after the joints

A few simple habits keep the new joints working:

  • Check joints after long freezing spells
  • Put movement joints on the planned maintenance inspection round
  • Keep racking legs and heavy point loads off floor joints
  • Keep traffic off new joints until the cure time is up

Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.

What happens if it’s left?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. Older rural buildings around Dane Hill move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Why us?

  • Failed material removed, not covered up
  • Coloured sealants to suit the setting, where available
  • CSCS-carded applicators
  • CHAS accredited

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Dane Hill, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Warn occupants and staff about the work

FAQs: Dane Hill

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

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.

Is Dane Hill too small for you to travel to?

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

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.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement with bays phased so the car park keeps operating.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
