Expansion joint sealing for Starling's Green sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Looking after the joints

Once the work is signed off, these steps help:

  • Brief car park operatives to protect joint lines during winter clearance
  • Put movement joints on the planned maintenance inspection round
  • Note which joints were done, when, and with what
  • Report split or peeling joint sealant early

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can call 01277 525 020 or email a schedule or drawings and send a picture.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.

How we handle expansion joint sealing in Starling's Green

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Starling's Green. We work on blockwork control joints, brickwork movement joints and podiums and floor movement joints, and what we’re called in for most is chipped joint edges on forklift routes and torn sealant in brick or block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Starling's Green is the same: the right product in a properly prepared joint.

Halls, schools and small commercial buildings near places like Starling's Green have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Starling's Green

Is Starling's Green too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Does a site in Starling's Green have to shut while its joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

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

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you work on car park ramps and decks?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

Why do our movement joints keep failing?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Different surfaces, different methods

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.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

Commercial clients in Starling's Green

Building owners and managing agents use us on everything from one building to a spread of sites around Starling's Green. Several sites can go on one quote, which keeps the paperwork simple.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Starling's Green can form part of a wider programme across Essex.

When to call us in Starling's Green

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Debris jammed in movement joints
  • Joints where the bead has lost adhesion
  • Spalled or broken joint edges in floors and decks
  • Movement joints with split or torn sealant

For a school such as Clavering Primary School, playground and building joints can be done in the holidays.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • How they’ll work around occupants
  • Whether primer will be used where the manufacturer specifies it
  • Their public liability cover

Choosing a commercial sealant contractor

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Surfaces we seal

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

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Starling's Green can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
