Common Problems With Vinyl Windows

  • Seal Failure

Double-pane and double-glazed windows have rubber seals to prevent humidity from infiltrating your home. Vinyl windows have the highest likelihood of broken seals within the first three years of being installed.

  • Expansion & Contraction

Vinyl replacement windows expand and contract like wood. This property contributes to broken rubber seals that cause air infiltration and poor insulation. Consistent expansion and contraction due to fluctuating temperatures can also cause cracks in vinyl frames.

  • Lack of Strength & Density

Vinyl windows lack strength and density because manufacturers use the minimum amount of material. Over time, vinyl frames can loosen due to expansion and contraction, which then leads to insulation problems and possible window damage.

  • Loss of Glass Area

Vinyl window frames with more density may have reduced glass area. This is usually done to improve the strength and durability of the frame. However, in this case, the aesthetics of the windows suffer and the view offered by the window becomes smaller due to thicker frames.

  • Poor Warranty Coverage

Some vinyl window manufacturers only issue warranties of 10 to 15 years, and they may only cover expenses amounting to the window’s actual cash value during that time.

"Our installation team, Josh and Mike, did a phenomenal job with the installation, cleanup, and "orientation" after the work was completed! We were totally satisfied with everyone that we dealt with before and after the installation...and would surely recommend Renewal by Andersen to anyone contemplating a window replacement project!"
