Wenco started making windows in 1962.  Every year since then we've added new designs and styles to our product line, and every year we've increased our capacity to produce them.  Due to a constantly increasing demand for WENCO Windows, we've grown to be one of the largest window companies in America.

Counted high among WENCO's strengths are our employees.  Numbering over 1,000, they are hard working and dedicated to the task of maintaining the craftsmanship and high quality standards our customers desire and have come to expect from WENCO.  These standards are maintained in every step of the manufacturing process with a very sophisticated corporate-wide system called Statistical Quality Control(SQC).  This system sets high standards for our employees and assures you of high quality products.

Windows are a major investment for any homeowner.  You deserve the promise and assurance from the manufacturer that they will perform and stand up to the ravages of time and weather.  That's why WENCO's warranties go far beyond its competition.  We guarantee  the insulating glass in our windows for the lifetime you own your home - and we've put that in writing.
