DON'T USE WINDOW WORLD A PIECE OF ***
Do not use window world company at all.They may sound cheap and nice but they are really a bunch of liars.
They promised us the best windows after we paid over 300 dollars for each window and what happened. After four months, the window's won't lock, they leak too much air, and they don't fit in their tracks. We tried to call the salesperson multiple times and all we can get is their assistant who keeps on telling us he is unavailable or he will be their shortly. Too much condensentaion on the windows along with the massive loss of air is definately not something energy efficient windows should be doing.
They never come and their entire office is officially run down.It is a terrible company and i hope you accuately get some professionals to fix your problem.
