About our expansion joint sealing in Millbank

We’ve 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 are 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 podiums and floor movement joints, and what we’re called in for most is previous reseals laid over old sealant and movement joints with split or torn sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Millbank it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Commercial clients in Millbank

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Millbank need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Move anything stored against the joints

Advice

Why act early in Millbank

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. Full removal and preparation is in every quote. For buildings around smaller places like Millbank, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Different surfaces, different methods

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints, or we visit if they don’t show enough.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Common problems we fix in Millbank

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.

Common reasons buildings call us in:

  • Brittle, chalky sealant on external joints
  • Damp inside where a wall movement joint has failed
  • Joints where the bead has lost adhesion
  • Previous reseals laid over old sealant

Hospitals like Queen Victoria Memorial Hospital (to the north-west of Millbank) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Comparing quotes

  • The named product and why it was chosen
  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

Maintenance after handover

To get the most from the new sealant:

  • Keep traffic off new joints until the cure time is up
  • Raise snow-clearing blades over deck joints where possible
  • Keep stones and debris out of open joint lines
  • Keep product details with the building records for the next reseal

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.

On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.

Millbank: questions and answers

Do you cover business parks and estates near Millbank, such as Chislet Business Park?

Yes. Our area takes in Millbank and its surroundings, with estates and business parks such as Chislet Business Park included. A few photographs and the unit address let us price the work.

Do you take on work at healthcare sites like Queen Victoria Memorial Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

What about RAMS and site documents?

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

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Can you work on car park ramps and decks?

Yes. Let us know the opening hours and which levels or bays have to stay available.

How much does the work cost?

We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.

Slabs, ramps and loading bays in Millbank

With the shore within about 3 miles, Millbank counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Central London is about 55 miles from Millbank. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

At places like Canterbury Industrial Park, which lies south of Millbank, joints are sealed a section at a time so operations carry on. Office parks like Chislet Business Park (to the south of Millbank) have decks, ramps and clad elevations whose joints take movement every day.
