Signs you need expansion joint sealing in Great Tey

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way unless width and product are reviewed.

What tends to prompt an enquiry:

  • Joints packed with grit and debris
  • Water getting into the wall through a failed joint
  • Expansion joints split through the centre of the bead
  • Sealant peeling off one face of the joint

Hospital campuses such as Halstead Hospital, 5.7 miles north-west of Great Tey, grow in stages, leaving movement joints wherever new blocks meet old.

Questions to ask before you book

  • Who will actually carry out the work
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Questions about Great Tey

Is Great Tey off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Earls Colne Business Park, by Great Tey?

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

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

What guarantee do you give on joint sealing?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

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. Removing asbestos is a job for asbestos specialists, not us.

Are you fully insured?

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

What causes movement joint sealant to fail?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Great Tey, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Send any specification or drawings in advance
  • Tell staff and tenants when we will be in
  • Share the asbestos register for older buildings

After the work

A few simple habits keep the new joints working:

  • Plan racking layouts so feet don’t land on a joint
  • Keep traffic off new joints until the cure time is up
  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can call the office on 01277 525 020 or email the details over and send a picture.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

General trades versus a specialist

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. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. Great Tey lies roughly 45 miles out from central London. The roads out of London are lined with trade parks and distribution sheds.

On a site such as Earls Colne Business Park (2.9 miles west of Great Tey), the movement joints are in car park slabs, paving and building elevations.
