Expansion joint sealing for businesses in Navestock Heath

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Quoting for work in Navestock Heath

What shapes the price:

  • The site’s rules and procedures
  • Removal of failed or old sealant
  • Travel to remote or island sites
  • How accessible the joints are

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Details that help us quote

A few photographs plus some basic facts will normally do. Please tell us:

  • The asbestos register, for older buildings
  • When you need the work done
  • What the building is and how it’s used
  • Any specification or named product

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

How we handle expansion joint sealing in Navestock Heath

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. The enquiries we see most involve expansion joints filled with dirt and stones and arrises breaking up along floor joints, across podiums and floor movement joints, cladding panel joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, in Navestock Heath it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Navestock Heath are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Questions we’re asked in Navestock Heath

Is Navestock Heath too small for you to travel to?

No. Places such as Navestock Heath are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

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

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

What happens if old sealant might contain asbestos?

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

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Do you guarantee expansion joint work?

The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Regular sweeping and inspection help the joints last.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Leave barriers in place until fresh joint sealant has cured
  • Keep stones and debris out of open joint lines
  • Keep product details with the building records for the next reseal
  • Keep scrapers and ploughs from dragging across joint sealant

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

Joints that move: notes for Navestock Heath

Navestock Heath 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, and where de-icing salt is spread in winter, open joints let it in. Central London is about 17 miles from Navestock Heath. The roads out of London are lined with trade parks and distribution sheds.

Hospital campuses such as Suttons Manor Hospital (1.6 miles west of Navestock Heath) grow in stages, leaving movement joints wherever new blocks meet old. Around Navestock Heath, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Surface by surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Movement on a scale no sealant is meant to absorb
  • A joint that has to be widened or re-detailed before it can work
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

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.

Joints and surfaces we work on

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

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For work around Navestock Heath, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Move anything stored against the joints
