The process

Our Repair & Refurbishment Services

1

Acrylic Window Polishing

Over time, even well-maintained acrylic windows can develop surface scratches or haziness that diminish optical clarity. Our professional acrylic window polishing service restores crystal-clear views without the expense of replacement.

When polishing is the right solution:

  • Surface scratches from cleaning or contact
  • Minor cloudiness or hazing
  • Reduced optical clarity over time
  • Preventive maintenance to extend window life
  • Cost-effective clarity restoration

Our polishing process:

  • Assessment of surface condition
  • Multi-stage polishing with specialized compounds
  • Restoration of original optical clarity
  • Application of protective treatments
  • Maintenance recommendations

  • Structural damage beyond repair
  • Outdated window design or configuration
  • Failed seals that cannot be effectively repaired
  • Upgrade to larger or differently configured windows
  • Severe optical degradation

Our replacement process:

  • Careful removal of existing windows
