FAQs: Rettendon

Is Western Industrial Estate, near Rettendon, within your area?

Yes, sites like Western Industrial Estate are within our area, along with the rest of Rettendon. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is a hospital such as Baddow Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. We name the proposed product in the quote.

How much does the work cost?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email a schedule or drawings with a description of the work.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

About our expansion joint sealing in Rettendon

For movement joints in Rettendon, photos and approximate lengths are the best start. We’ll come and look where photographs don’t show enough. To discuss the joints first, phone 01277 525 020 or use the quote form. We work on cladding panel joints, car park decks and ramps and podiums and floor movement joints, and the failures we are asked to look at most are torn sealant in brick or block movement joints and expansion joints filled with dirt and stones. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Rettendon is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Halls, schools and small commercial buildings near places like Rettendon have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Our workmanship is guaranteed for 12 months, in Rettendon as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

Surfaces we seal

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

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Inspect exposed joints once the cold weather has passed
  • Avoid parking heavy plant or pallets on joint lines
  • Treat a small split as a warning, not a cosmetic issue
  • Put movement joints on the planned maintenance inspection round

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Rettendon need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot

Advice

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

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.

Floors, slabs and movement joints in Rettendon

The 3 miles around Rettendon take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Rettendon sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

If you manage units on an estate such as Western Industrial Estate, 2.3 miles east of Rettendon, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Hospital campuses such as Baddow Hospital, 4.2 miles to the north-west of Rettendon, grow in stages, leaving movement joints wherever new blocks meet old.

Do you need expansion joint sealing in Rettendon?

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

Clients usually get in touch after noticing one or more of the following:

  • Spalled or broken joint edges in floors and decks
  • Joints where the bead has lost adhesion
  • Weathered movement joint sealant that no longer flexes
  • Movement joints with split or torn sealant

Across sites such as Eastern Industrial Estate, 2.9 miles east of Rettendon, floor and movement joints can be sealed in phases so units keep working.

What your quote should include

  • Their plan for phasing and protecting the area
  • Their pre-qualification and accreditations
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?
