About our expansion joint sealing in Dagenham Green

For movement joints in Dagenham Green, photographs and approximate lengths are the best start. Send them through our quote form, and we will arrange a site visit if needed, then send a fixed quote that names the sealant. To discuss the joints first, call the office on 01277 525 020 or email us. Most enquiries involve chipped joint edges on forklift routes and joints packed with grit and debris, on brickwork movement joints, cladding panel joints and podiums and floor movement joints. One point of contact handles commercial sealant work in Dagenham Green from the first photographs to the final walk-round, whether it’s one building or several.

Areas such as a loading bay or car park deck in Dagenham Green usually have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Leave barriers in place until fresh joint sealant has cured
  • Clear dirt from joint lines during routine cleaning
  • Avoid parking heavy plant or pallets on joint lines
  • Report split or peeling joint sealant early

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Photos, joint lengths and drawings come to us, or we visit.
  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. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot

Advice

Building owners, agents and FMs in Dagenham Green

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Your questions answered

Can you cope with the access rules in a London building?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough

Is hospital work, at somewhere like Grays Court Community Hospital, something you do?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you guarantee expansion joint work?

It’s backed by our 12-month guarantee. Tell us right away if a joint we sealed gives trouble in that time.

Is Dagenham Green in your area?

Yes. Dagenham Green falls within our area, and the simplest way to start is to call the office on 01277 525 020 or email us.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Where floor joints take the most wear near Dagenham Green

In London, decks, bays and service yards usually have to keep running, which is why we work a few bays at a time. The 3 miles around Dagenham Green take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

In a school such as Marsh Green Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For a store at a site such as Merrielands Retail Park, under half a mile north-west of Dagenham Green, the service yard and goods-in area are where joints break down first. Large sites such as Grays Court Community Hospital, 0.8 miles to the north-east of Dagenham Green, have car parks, service roads and long elevations with movement joints in brick and panels.

Cost factors for movement joints

Your fixed quote is built from the real scope. It takes account of:

  • The site’s rules and procedures
  • The size and state of each joint
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Why deal with it now?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
