Every warranty in this industry sounds impressive in a headline. The difference is what’s written down. Sightline Windows & Doors puts both layers of your coverage - the product and the labor - in writing on the quote, with the durations stated, before you commit to anything.

Layer 1: The Manufacturer’s Product Warranty

Every window and door we install carries its manufacturer’s written warranty on frames, hardware and insulated glass - including seal failure (the fogging between panes that means the insulation value is gone). Durations vary by product line and are printed on your quote for the exact units you choose, so you can compare lines on coverage, not just price.

Layer 2: Our Labor Warranty

The best unit fails if it’s installed out of square or sealed wrong. Our own installation crews warranty their workmanship - flashing, anchoring, insulation, sealing and finish - in writing, with the duration stated on your contract. If an install defect appears inside the labor-warranty period, we fix it at no cost. No blame-the-manufacturer routine.

What That Means in Practice

Coverage That Goes Beyond the Basics

On qualifying manufacturer lines - the coverage schedule is stated on your quote - protection extends to the failures homeowners actually worry about:

  • Accidental glass breakage - everyday accidents, not just defects
  • Hurricane glass breakage - coverage that holds when the product does its job in a storm
  • Delamination - the laminated interlayer separating from the glass
  • Labor and materials - both layers, together, in writing

Transferable Protection

Transferable Protection

Selling your home? Your warranty coverage is transferable to the new owner (conditions and registration windows vary by line - we include the transfer terms with your closing documents), and documented transferable protection on new windows and doors is a genuine listing asset.
