Expansion joint sealing near Balstonia

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Balstonia can sit alongside others in a wider programme.

Expansion joint sealing in Balstonia, done properly

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you have debris jammed in movement joints and spalled or broken joint edges in floors and decks, we can put it right, on cladding panel joints, blockwork control joints and podiums and floor movement joints alike. Most enquiries from Balstonia start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural business units around smaller places such as Balstonia often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common problems we fix in Balstonia

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.

Look out for the following:

  • Weathered movement joint sealant that no longer flexes
  • Debris jammed in movement joints
  • Damp inside where a wall movement joint has failed
  • Joints where the bead has lost adhesion

For a school such as St Joseph's Catholic Primary School, playground and building joints can be done in the holidays.

Our contractor checklist

How the job changes by surface

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.

Expansion joint sealing around Balstonia: how the place shapes the job

Balstonia sits close to the coast, within about 2 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Less than 3 miles from Balstonia there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Phasing is what makes joint work possible on busy sites such as Thames Industrial Park (3 miles south of Balstonia): one bay, aisle or car park row at a time. If you manage units on an estate such as London Gateway Logistics Park, which lies east of Balstonia, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Balstonia is about 4 miles south of Basildon, in Thurrock. Businesses, contractors and managing agents in Balstonia can call on us for movement joints. Across Thurrock, 27 places are covered, including Balstonia. There’s a separate page for London, about 23 miles away.

Postcode districts covered here: SS17. Buildings on Link Road, Wharf Road and Poley Road are within our area for movement joints. Just outside Balstonia, we also work in Stanford-le-Hope (1 mile north-east), Horndon on the Hill (1 mile west), Corringham (1 mile east), Fobbing (2 miles north-east) and Langdon Hills (3 miles north). Nearby towns on our patch include Grays (5 miles south-west), South Ockendon (6 miles west), Chadwell St Mary (3 miles south-west), Aveley (8 miles west), Tilbury (5 miles south-west) and South Stifford (6 miles south-west).

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Balstonia need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Point out any areas we must not close

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

Your questions answered

Can being near the sea in Balstonia affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Is Balstonia too small for you to travel to?

No. Places such as Balstonia are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

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

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How the quote is worked out

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

  • Any access equipment needed
  • The site’s rules and procedures
  • How much there is to seal
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or use the quote form.

Why act early in Balstonia

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 tell you honestly. For buildings in places like Balstonia, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
