Louisville, Colorado Customer Reviews

Great price and professional installation. The buying process was easy and everything was on time. We only needed 1 window because we live in a small condo. If I ever need windows again, I will call them first.

Throughout the experience with Window World, we were happy with the professionalism of each individual we worked with, from Justin Cropper who did our estimate, demonstration & measurements to the three men, Edgar and his team to do excellent work on the installation! We love the look of these new windows! We love the level of efficiency that is already making a difference in the internal warmth of our house. They are by far the best available windows at a price that is reasonable and fair.

We had a top notch experience with Window World. Our salesman Mike was very informative and timely, and the pricing was excellent. Our install was very smooth, efficient and well done. We are very pleased with the results and highly recommend Edgar for installation services.
