About our expansion joint sealing in Greensted Green

For movement joints in Greensted Green, photographs and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. You can also ring 01277 525 020 or email the details over to talk the joints through. We work on car park decks and ramps, blockwork control joints and brickwork movement joints, and what we’re called in for most is water dripping through deck or ramp joints and debris jammed in movement joints. Whoever orders the work in Greensted Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Greensted Green are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Confirm the product named in the specification

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email the details over with what you know.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What sets the cost

What shapes the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Whether the work must be split into stages

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

However big the job, these details speed things up:

  • The site address and postcode
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

To get a fixed quote, speak to us on 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Where we work in Greensted Green

Questions we are asked in Greensted Green

Is North Weald Industrial Estate, near Greensted Green, within your area?

Yes, sites like North Weald Industrial Estate are within our area, along with the rest of Greensted Green. Send details of the unit and the work through our quote form for a quick quote.

Would you work within a site like St. Margaret's Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

What happens if it rains on the day?

A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. We agree a revised date with you.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

Can staff carry on working while you are here?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Why it’s worth doing now in Greensted Green

Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme. We can split the scope into urgent and planned. Older rural buildings around Greensted Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

After the work

Once the work is signed off, a little attention goes a long way:

  • Include every elevation and deck joint in periodic inspections
  • Keep racking legs and heavy point loads off floor joints
  • Clear dirt from joint lines during routine cleaning
  • Check joints after long freezing spells

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can ring 01277 525 020 or send photos by email and send a picture.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.

Floors, slabs and movement joints in Greensted Green

Greensted Green sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. Greensted Green is about 19 miles from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.

On industrial estates such as North Weald Industrial Estate, 2.2 miles west of Greensted Green, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Another example is Hallsford Bridge Industrial Estate, which lies east of Greensted Green, where floors and yards would be done in stages around the occupiers. Large sites such as St. Margaret's Hospital (to the west of Greensted Green) have car parks, service roads and long elevations with movement joints in brick and panels.

Greensted Green is about 6 miles south-east of Harlow, in Essex. Any commercial site in Greensted Green is covered, for single jobs and planned programmes alike. Greensted Green is one of 644 places we cover in Essex for movement joints. Our London page has more on work in that area (19 miles or so).
