Expansion joint sealing in Eastwick

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you are dealing with spalled or broken joint edges in floors and decks and debris jammed in movement joints, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Eastwick is the same: the right product in a properly prepared joint.

In and around smaller places like Eastwick, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

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

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Working within restricted access windows

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • A wide shot and a close-up of the area
  • The product your specification calls for

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.

Building owners, agents and FMs in Eastwick

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Why deal with it now?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed. Converted and older buildings near places like Eastwick tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • 12-month guarantee on workmanship
  • CHAS accredited
  • A range of standard colours, depending on the product

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Cracking or settlement that calls for an engineer’s assessment
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Joints and surfaces we work on

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

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Eastwick need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability 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. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Let building users know which areas are affected

Where floor joints take the most wear near Eastwick

Eastwick is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. Less than 3 miles from Eastwick there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Another example is Oaks Retail Park, 1.1 miles east of Eastwick, where floors and yards would be done in stages around the occupiers. In a school such as Pemberley Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak. Parks like Harlow Enterprise Centre (to the south-east of Eastwick) combine paved areas, car parks and building elevations, each with joints that move.

Eastwick is about 2 miles north-west of Harlow, in Hertfordshire. We cover commercial sites throughout Eastwick. Across Hertfordshire, 371 places are covered, including Eastwick. There’s a separate page for London, roughly 21 miles from Eastwick.

Commercial sites across CM20 are covered for movement joints. We also cover Little Parndon (1 mile south), Gilston (1 mile north-east), Great Parndon (2 miles south), Roydon (2 miles south-west) and Staple Tye (2 miles south) for movement joints. Further afield, our area takes in Stevenage (14 miles north-west), Bishop's Stortford (7 miles north-east), Welwyn Garden City (12 miles west), Hoddesdon (5 miles south-west), Cheshunt (8 miles south-west) and Hatfield (14 miles west).

FAQs: Eastwick

Is a smaller place like Eastwick outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Princess Alexandra Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What do you charge?

Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email a schedule or drawings with a description of the work.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Which product is best for expansion joints?

Whatever suits the joint and the specification. We name the proposed product in the quote, so you know what’s going in.

After the work

Regular inspection catches problems early. Specifically:

  • Leave barriers in place until fresh joint sealant has cured
  • Record the sealant used and the date in the O&M file
  • Raise snow-clearing blades over deck joints where possible
  • Inspect movement joints alongside other routine building checks

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or email drawings and photos with photographs.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
