Expansion joint sealing across Barking Riverside

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

Surface by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Expansion joint sealing in Barking Riverside, done properly

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. The enquiries we see most involve damp inside where a wall movement joint has failed and new sealant over old, now failing, across brickwork movement joints, cladding panel joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Barking Riverside, that means joint design, primers and backing rod as standard.

Around Barking Riverside, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Treat a small split as a warning, not a cosmetic issue
  • Record the sealant used and the date in the O&M file
  • Reopen bays and walkways only after the stated cure time
  • Check joints after long freezing spells

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 so future maintenance isn’t guesswork.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.

Do you need expansion joint sealing in Barking Riverside?

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

What tends to prompt an enquiry:

  • Leaks through car park deck joints onto the level below
  • Expansion joints split through the centre of the bead
  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris

At a retail site such as Gallions Reach Shopping Park, which lies west of Barking Riverside, trolleys, cages and cars run over floor and slab joints all day.

What your quote should include

  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed
  • What level of public liability insurance do they hold?
  • The named product and why it was chosen

Our contractor checklist

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Our process

Inspect, seal, sign off: every visit follows that pattern. 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. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Point out any areas we must not close
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

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

FAQs: Barking Riverside

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

Yes, we plan every London job around the building’s own access rules. 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 a hospital such as Barking Community Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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, because fresh silicone will not bond with aged silicone.

Do you guarantee expansion joint work?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you reseal car park expansion joints?

Yes, we do. These joints take wheels, salt and water, so product choice matters, and we’ll tell you if any edges need repairing first.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What affects the price in Barking Riverside

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Access and working height
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • How much existing material needs removing

Pricing movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Access details, including height
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.
