They did a great job. The communication from the start was great and carried throughout the whole install process. Very satisfied with the quality of the windows and the company.

Guardian Windows replaced all thirteen of our exterior window, which had been in place since the 1970s. They did a terrific job, and the windows look amazing! We are so happy that we decided to work with them!

We were approached to be an advertising home because we live on a corner. Overall it was a good price for a quality window with a good warranty. The office staff that e-mailed me are great at arranging everything, providing information, and answering questions.We were lucky it only took about a month to get the windows made and then they were quick to schedule the installation. We were very blessed to have perfect weather that day and they were able to get them all installed in one day. Very smart to measure again before starting to verify they brought the right size windows. Installers were kind and considerate.*tip - make sure to double check that what you want is what is ordered. We received the wrong sashes for the bathroom window but that was quickly corrected within the next month at no charge. Happy to have a bathroom window that can open from the top.Our house feels more insulated and there is less noise from the outside. Love the new window feel and look.

We had the pleasure of working with Guardian Windows here in Loveland, CO. Everything went very smoothly from start to finish. The whole team was friendly, knowledgeable, and professional. Our installation day was fast and efficient, the install team was awesome! Our house feels and looks so much better with the new windows. We are definitely very pleased with the results! We have had the windows for about 5 months now and have not had any problems, they 1000% help with the insulation!

We thoroughly enjoyed our experience with the Guardian Windows team. They gave us the quotes we needed in order to decide how much we wanted to do now and later. Our quote is good for 3 years so we can plan accordingly.The sales rep was very knowledgeable and answered all of our questions.The guy who came for precise measurements was on time. Our windows came in before the 4-6 weeks and we were aware of what we needed to prepare ahead of time for installation. They were a bit late on installation day but they were efficient and knowledgeable in installing our windows after they arrived. Overall, we are impressed and love being able to see through our windows again!

We are very satisfied with our new windows. The process was very smooth and quick. Our one minor complaint would be that there were a decent amount of caulk smudges left on the windows which required us to take all the windows out to clean after the install was complete.

I am very pleased with my new windows. The young men were right on time. They said they would arrive between 9 and 10. They arrived at 9:30. They did a super job and were very efficient and helpful. The clean up was over the top. I would definitely recommend Guardian Windows.
