Advice

About our expansion joint sealing in Netteswell

For movement joints in Netteswell, photos and approximate lengths are the best start. Send them through our quote form, and we will arrange a site visit if needed. To discuss the joints first, call 01277 525 020 or send details through our quote form. If you have weathered movement joint sealant that no longer flexes and movement joints with split or torn sealant, we can put it right. Facilities teams, main contractors and managing agents in Netteswell tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural business units around smaller places such as Netteswell often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Commercial clients in Netteswell

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Damaged metal nosings or cover plates over a joint
  • A joint that has to be widened or re-detailed before it can work

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer.

What we seal

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

Joints that move: notes for Netteswell

The planned town of Harlow is on Netteswell’s doorstep. Industrial estates in planned towns were built in phases, so whole rows of units can need their floor joints done at once; one programme for a whole row of units is often simplest. Rainfall across the South East, Netteswell included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

For a store at a site such as Oaks Retail Park, which lies north of Netteswell, the service yard and goods-in area are where joints break down first. In a school such as Freshwaters Primary Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Netteswell is about 1 mile west of Harlow, in Essex. Commercial clients in Netteswell can call on us for movement joints, as part of our coverage of Essex. Across Essex, 644 places are covered, Netteswell among them. For work in that direction, see our London page.

Netteswell: questions and answers

Our unit in Harlow is decades old: is it worth resealing the floor joints?

Normally, yes, as long as the joint edges are still sound. We will look at the joints, recommend a product for the traffic and movement, and say if any edges need repair before sealing.

Does your area include sites such as Oaks Retail Park, near Netteswell?

Yes. Our area takes in Netteswell and its surroundings, with estates and business parks such as Oaks Retail Park included. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

What guarantee do you give on joint sealing?

A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Different surfaces, different methods

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.

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.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Brief car park operatives to protect joint lines during winter clearance
  • Check joints after long freezing spells
  • Leave barriers in place until fresh joint sealant has cured
  • Keep stones and debris out of open joint lines

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.

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. Keeping the seal sound avoids all of that.

Signs you need expansion joint sealing in Netteswell

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.

Typical triggers for a call:

  • Water dripping through deck or ramp joints
  • Spalled or broken joint edges in floors and decks
  • Previous reseals laid over old sealant
  • Joints packed with grit and debris

Hospitals like Princess Alexandra Hospital (to the west of Netteswell) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?
  • Their approach to joint depth and backing
  • The named product and why it was chosen
