This company has been advertising the $189.00 window since 1995. As advertised the $189.00 window is a buy-up window. Low-E glass and aluminum trim are not included in the base price. There is also a one time $150.00 trip charge. The final price is around 400.00 or more per window. The 3 men pictured in the company ads are standing on windows that have tempered glass in the window sashes. Tempered glass can support the weight of a small truck. This company spends thousands of dollars every month on advertising. They pay their installers $30.00 per window. You only get what you pay for so steer clear of these guy's!
