  • Vinyl: Made from polyvinyl chloride (PVC) and ultraviolet light stabilizers meant to protect against sunlight that can break down the material. They don't require maintenance.
  • Wood: Require heavy maintenance including painting and sealing. More expensive to purchase but easier than vinyl to fix.
  • Aluminum and Steel: Strong and require little maintenance but conduct heat, making them poor insulators. High-end models have thermal breaks between the interior and exterior surfaces.
  • Fiberglass and Composite: Exceptionally durable, dimensionally stable and provide better insulation than those made from wood or uninsulated vinyl. High installation cost.

Common Repairs

A few common issues include:

  • Broken Frame: Patch a broken window frame with the same material it’s made from. Wood might rot beyond the point of repair, requiring replacement.
  • Broken Sash Interlock: A broken sash interlock greatly increases the chance of leaks and drafts.
  • Broken/Leaking Nail Fin: Nail fins are strips used to attach a window frame to a stud opening. Sometimes, these fins may break or corrode and need replacement.
  • Leaking Windows: Over time, screws may corrode and require replacement. Rot could also ruin the rest of the wood, requiring replacement.
