The technicians did great and I had a great experience with the technicians that fixed my blinds.
After they replaced my window blinds it started to have problems again so I called to get scheduled and unfortunately I had a work emergency so had to reschedule once again. I didn't think anything of it since the company has accommodated me pretty well and worked around my schedule so I don't have to leave work so early.
The person who answered the phone her name is Diamond. She was very rude about me having to reschedule like it was such an inconvenience to her and gave me attitude like she was trying to hang up and she didn't even reschedule me. It's so disappointing since I had a great experience with them at first. She even sighed and was like "it's pretty late to be rescheduling but okay I guess". This lady shouldn't be answering the phone if she acts like that. I planned to give 5 stars also since the technicians were so great but I did not have a good experience with this lady.

Everyone at this company really knows they're jobs. Had a wonderful experience with this company from start to finish. Had all our windows replaced and they put them all in two days and did a excellent job!

I couldn’t be happier with Window World! Scott, Alex, and the installation team did an excellent job installing our new vinyl windows and doors, taking care of every detail and finishing touches. Their craftsmanship and attention to detail really stood out.
Mahina managed the project seamlessly, handling scheduling and customer service, while Rob provided helpful guidance and explained the products clearly. The whole team was professional, courteous, and thorough, making sure everything not only looks great but functions perfectly.
If you want top-quality installation with a team that truly cares about the details, I highly recommend Window World!

Earl, Cole, and Scott were amazing! They were so kind and professional. They were nice enough to drape our furniture to keep it clean, and they cleaned up extremely well when they were done. I highly recommend this company and crew!

Will the replacement windows be installed from the inside or outside?

Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?
Window World installs replacement windows year-round. An average installation will take only one day. Our crews install one window at a time and are trained to do what they can to minimize heating/cooling loss. The energy savings from your new windows will recover any incremental energy costs incurred during their installation many times over during their lifetime.
How can I prepare my house for my replacement windows?
Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company. Please provide our installation expert with a clear path to the window(s) being replaced by moving anything that may be in the way. It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
How long will it take to get my replacement windows? How much time should I allow for the installation?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken.
