Performance for Life Guarantee

A bold new commitment from Coastal.

We engineer our premium external hardware to perform for the full lifetime of the door or window - backed by genuine guarantees, not assumptions or marketing claims.

Proven, not just promised.


More than a lifetime product guarantee


Performance for Life now goes further.

For BLU, Duratique and EDWIN ranges, Coastal will not only replace qualifying failed products under guarantee - we will also cover the cost of replacement.

That means:

  • Reduced hassle
  • No hidden costs
  • Less friction for you and your customer

This is where most guarantees stop. Ours doesn't.


Why we can make this promise

Engineering for Longevity

Performance for Life starts at the design stage.

Every product is engineered by our in-house team of specialists to:

  • Withstand repeated use over many years
  • Maintain structural integrity under load
  • Retain its appearance in exposed conditions

It’s not just about making hardware that looks good on installation day - it’s about ensuring it still performs years down the line.


How we test it

We don’t rely on assumptions. We test extensively to ensure our hardware performs under real-world conditions.

Salt Spray Testing

Salt spray testing accelerates corrosion conditions to simulate years of environmental exposure.

Our hardware is subjected to controlled saline environments to assess:

  • Corrosion resistance
  • Finish durability
  • Material performance over time

This is particularly critical for coastal installations, where salt exposure can quickly degrade inferior products.

Mechanical Cycle Testing

Handles, hinges and locking systems are tested through thousands of cycles to replicate years of use.

This allows us to evaluate:

  • Wear resistance
  • Mechanical integrity
  • Long-term performance under repeated operation

Because durability isn’t just about surviving the environment — it’s about performing every time the product is used, for life.

Real-World Simulation

Laboratory testing is only part of the picture.

We also assess performance in real-world conditions, including:

  • Exposed coastal environments
  • High-traffic installations
  • Long-term product use in the field

This ensures our products don’t just pass tests; they perform where it matters most.


The Proof

"Product failure is our greatest source of learning." - Loren Jenner, Managing Director, Coastal Group


Why choose hardware built to perform for life?

  • Reduced callbacks
  • Long-term reliability
  • Peace of mind
  • Protect your reputation

True sustainability thinks long term. Hardware should not need replacing, refitting or revisiting.
