Windows Warranty

Lifetime Warranty on White and Solid Cream Windows

Twins Windows & Doors Ltd. are warranted against such defects in material and workmanship that might result in rotting, cracking, warping, pitting, corroding, peeling, blistering or non-uniform fading discolouration of the window frame and sash members for the lifetime of the window.

Painted windows Carry a 15-Year Warranty

Corner welds on painted windows may fade over time at a different rate than the painted window. Touch-up paint is available from your dealer or directly from Twins Windows & Doors Ltd.
