Expansion joint sealing across Great Canfield

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

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. If others near Great Canfield need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

How we handle expansion joint sealing in Great Canfield

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. We work on cladding panel joints, brickwork movement joints and precast concrete panel joints, and the failures we are asked to look at most are chipped joint edges on forklift routes and water dripping through deck or ramp joints. A single leaking joint is often how a building in Great Canfield first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Jobs around smaller places like Great Canfield are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or email the details over and we will come back to it.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • A joint that has to be widened or re-detailed before it can work
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Waterproofing layers buried beneath the sealant

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.

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.

Your questions answered

Will our site in Great Canfield have to close for joint sealing?

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

Is a smaller place like Great Canfield outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Does the weather affect joint sealing?

A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.

Expansion joint sealing around Great Canfield: points for this area

Great Canfield sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Great Canfield is about 29 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Phasing is what makes joint work possible on busy sites such as Parklands Business Centre (2.7 miles south of Great Canfield): one bay, aisle or car park row at a time. Warehouse floors on estates like Blue Gates Industrial Park, 2.4 miles north of Great Canfield, carry pallet trucks and forklifts over every saw-cut joint.

Great Canfield is about 3 miles south-west of Great Dunmow, in Essex. Anywhere in CM6, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Great Canfield is one of 644 places we cover in Essex for movement joints. We also cover London, around 29 miles from Great Canfield.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Report split or peeling joint sealant early
  • Keep racking legs and heavy point loads off floor joints
  • Put movement joints on the planned maintenance inspection round
  • Reopen bays and walkways only after the stated cure time

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.

What sets the cost

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • The product specified

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • How the joints are reached, and at what height
  • The postcode of the building
  • Whether an asbestos survey exists
  • Any dates the work must fit around

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Why deal with it now?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. One visit to deal with every failing joint makes more sense than several trips to a place like Great Canfield. Photos of every joint help us quote for the whole job.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
