Frequently Asked Questions
How does Windorco handle window installation?
Installers use tarps and usually change one or two windows at a time. New windows are washed inside and out, and debris is removed when the job is finished.
Can Windorco prepare a quotation without visiting the property?
Most orders can be quoted by phone or email after a few questions; the company can also arrange a free estimate at the property.
Are Windorco’s wood windows designed for replacement openings?
The company designs its wood windows in a variety of thicknesses for new construction and replacement. Single-hung, double-hung and horizontal-slider models fit the pocket left after removing an original wood sash.
