About our expansion joint sealing in Theydon Garnon

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. We work on cladding panel joints, podiums and floor movement joints and precast concrete panel joints, and what we’re called in for most is damp inside where a wall movement joint has failed and movement joints with split or torn sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Theydon Garnon, preparation and product choice get the time they need.

For a site near Theydon Garnon, measurements and photographs up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Brief car park operatives to protect joint lines during winter clearance
  • Check joints after long freezing spells
  • Clear dirt from joint lines during routine cleaning
  • Report split or peeling joint sealant early

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Our process

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Smaller jobs around Theydon Garnon can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed

Related advice

Leave it or put it right?

A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Halls, stores and units around places like Theydon Garnon may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What the job involves on each surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.

Where floor joints take the most wear near Theydon Garnon

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At least three named trading, business or retail sites lie within about 3 miles of Theydon Garnon. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

For a school such as Theydon Bois Primary School, playground and building joints can be done in the holidays. Hospitals like Saint Margaret's Hospital, 2.3 miles to the north of Theydon Garnon, have multi-storey or surface car parks whose joints carry vehicles round the clock. Across sites such as Epping Forest Shopping Park, 2.5 miles south-west of Theydon Garnon, floor and movement joints can be sealed in phases so units keep working.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Movement on a scale no sealant is meant to absorb
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Your questions answered

Is Theydon Garnon off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you cover business parks and estates near Theydon Garnon, such as Hobbs Cross Business Centre?

Yes, sites like Hobbs Cross Business Centre are within our area, along with the rest of Theydon Garnon. Send details of the unit and the work through our quote form for a quick quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Can staff carry on working while you are here?

In the majority of cases, yes. Phased work can be planned so areas stay in use.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What exactly is a movement joint?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably and the way they’re sealed is similar.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
