The Window Factory Reviews Five Stars,

Windows look great, had 3 sliding windows installed today. James was a big help and the installers were very friendly.
We needed 2 sliding doors and 3 windows replaced, Steve came out and gave us a quote it was fast and easy. The installation was great and they cleaned up after themselves. The windows and doors look great thanks guys!

Although we eventually went with a company that offered cheaper brand and did not work with Window factory on our project, I still highly recommend them to anyone who is considering a windows or door replacement job. James was professional and knowledgeable. We also visited their show room and saw their products, they seemed to be of high quality. It is worth having at least a consultation with the company.

One of the best experiences I’ve had as far as professional grade work and great customer service goes. They were about 3 weeks late to install but the staff stayed in contact with me and always kept me informed. i will be referring their services to everyone i know 20/10 great job.

Competitive quote, got it financed which could be an annoying process but everything went smoothly. Will be using their services again.

Owning, maintaining, and renovating multiple properties in the Los Angeles area is always a stressful task. Thankfully, with the great aid of The Window Factory, I was able to get great service and installation on a couple doors and several windows. They were communicative and knowledgeable about their product as well as prudent in updating me on extended lead times. Professional, organized, and clean, I was very happy with how my final product turned out and I look forward to continuing business with The Window Factory in the future.

Good team of individuals throughout. Very thorough consultation with Steve. I needed to understand why my home was having leaks around my existing windows during the rainy season. I was happy to order the proper windows for my replacement rather than a "copy paste" dealer window. The new windows have not only enhanced the appearance of my home but also significantly improved our energy efficiency. I am genuinely satisfied with the results and would highly recommend their services to anyone seeking professional window installation.
