How we handle expansion joint sealing in Southend

We have been sealing expansion and movement joints for over 20 years, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, car park decks and ramps and cladding panel joints, and the usual reasons a site gets in touch are new sealant over old, now failing and sealant pulling off the joint face. A specialist sealant contractor works differently from a general builder: on jobs in Southend, preparation and product choice get the time they need.

Jobs around smaller places like Southend are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we will come back to it.

Traffic, movement and joints around Southend

At about 46 miles from central London, Southend is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Southend sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

On a site such as Fronds Park Business Park, which lies south of Southend, the movement joints are in car park slabs, paving and building elevations.

Southend is about 5 miles north-east of Thatcham, in West Berkshire. Our applicators travel to Southend for work on movement joints. Our West Berkshire coverage takes in 140 places. There’s a separate page for Reading, roughly 7 miles from Southend.

Work on movement joints is covered throughout RG7. Among the streets we cover are Heath Road, New Way and Cock Lane. We also cover Tutts Clump (1 mile north-west), Beenham Stocks (1 mile south), Beenham (1 mile south), Stanford Dingley (1 mile north-west) and Chapel Row (2 miles south-west). Bigger towns within reach include Newbury (8 miles west), Thatcham (5 miles south-west), Burghfield Common (4 miles south-east), Speenhamland (8 miles west), Fords Farm (5 miles east) and Little Heath (4 miles north-east).

Landmarks near Southend

Locally, jobs take us to sites close to The Queens Head pub, among other places. Southend’s nearest station is Aldermaston station, about 2.1 miles south. Other landmarks nearby include Thames Valley Police Museum (3 miles east) and Yattendon Castle (3.6 miles north-west). The countryside around Southend includes Moor Copse Nature Reserve and Hosehill Lake.

Signs you need expansion joint sealing in Southend

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.

What tends to prompt an enquiry:

  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Expansion joints split through the centre of the bead
  • Weathered movement joint sealant that no longer flexes

Schools like Bradfield C.E. Primary School often have long brick elevations with movement joints that age quietly.

What your quote should include

  • How the joint faces will be prepared and primed
  • Their plan for phasing and protecting the area
  • How long is the guarantee, and what does it include?
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Southend can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

What sets the cost

The price varies from site to site. It mainly depends on:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • Phasing around occupants
  • Site requirements such as inductions and permits

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.

General trades versus a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Surface by surface

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Concrete or masonry repairs along the arrises
  • Movement on a scale no sealant is meant to absorb
  • A joint that has to be widened or re-detailed before it can work

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

Where we work in Southend

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

Southend: questions and answers

Is a smaller place like Southend outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Fronds Park Business Park, near Southend, within your area?

Yes. We cover Southend and the area around it, including industrial estates, business parks and retail parks such as Fronds Park Business Park. Send details of the unit and the work through our quote form for a quick quote.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do your applicators hold CSCS cards?

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

Why has the sealant in our expansion joints split?

Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
