What great customer service. I called about a leaking seal on our window. Lisa answered the phone with a smile in her voice. She quickly provided me with the information that was needed to replace the window. I sent her an email with the documents needed, and within 15 minutes, I had a reply that the replacement was on the way.

Had trouble with the lock on my slider., so I phoned Viwinco, and they truly stand behind their products. Their service team is A+! Clayton and Tyler came out quickly and repaired our door. I can’t say enough about their excellent customer service and the way they stand behind their products. I highly recommend both the doors and the company. I had already recommended the doors to my stepson, and he just purchased them. Now I’ve been able to share the company’s customer service. Great company and great people. Thanks Clayton and Tyler!

We had the technicians come over to replace a huge oversized window. There were 4 of installers and they all acted professionally and got the window installed. Excellent quality and the company was a pleasure to work with! I highly recommend! The product was well put together and during shipment they had it extremely well protected. Couldn't be happier!

Viwinco customer care team is the best. From start to finish they were swift and articulate describing the replacement process. They provided how to videos to ensure the installation of the compromised sashes were installed properly. Lisa & Hailey were instrumental in making the experience smooth and painless. Thank you Lisa & Hailey!

I have had a couple window failures on my Viwinco windows at my beach house. Michael has always been very responsive in getting back to me to order new windows and get them installed. I recently had the glass in my sliding door fog up and Michael was able to get new glass for me quickly and sent out Tyler and Clayton to install the glass. Tyler and Clayton were great guys and did an excellent job installing the new window. Since the house is ocean front the pieces that hold the glass in place get brittle and one of the trim pieces broke during installation. The guys quickly got another piece on order and will be back out soon to install. I highly recommend this group as the service has been excellent.

I recently needed some parts and after filling out the online request the support team reached out to me the next day! Lisa was fantastic and consolidated things into a simple order with a clear timeline! My windows are over 10 years old and have been happy with them from day 1!

I had an excellent experience with Lisa. She was very friendly, professional, and very helpful throughout the entire process. My questions were answered promptly, and she went above and beyond to make sure my issue was resolved. It's refreshing to receive such attentive and courteous service. I highly recommend Lisa.

Very happy with my windows. Had an issue with a window so i called customer service. Lisa made the process to get replacement sashes simple. I gave her the numbers on the windows sent a picture and I had my replacement windows in 3 weeks. Thanks again Lisa.

September 2026: This is an update to our prior review. Michael, Tyler and Clayton were fantastic AGAIN. We had another window that needed to be replaced. It was under our lifetime warranty. Clayton and Tyler showed up on time, were very careful, and did a great job. This window was really large and in a tight spot. The customer service is outstanding. We waited until after a number of heavy rains to write this review and the new window and the install are doing fine. Marci in Swansboro, NC This 5 plus star review is for ViWinco customer service, window warranty, replacement scheduling and installation services. We worked with Sarah Siegel, Michael Clark, Tyler Lefenstey and Clayton James to replace the glass on two very large window panes. From the time of our first reporting the issues, starting with Sarah, through the organization of installation with Michael, and the hands-on terrific work and work-ethic of Clayton and Tyler, we were immensely pleased with ViWinco service. They honored the warranty with no issues, Michael stayed in touch throughout the scheduling process, and on the day of installation Clayton and Tyler called to let us know they were going to be a bit late. When they arrived they were courteous, professional, and stayed late to make sure the windows were carefully replaced. Clayton and Tyler did a great job cleaning up after their work and Michael followed up to ensure that we were satisfied. Excellent work by each individual and as a team. Thank you! Marci and Joe, Swansboro NC

Viwinco really delivered on their warranty. They replaced 2 panes that had gotten foggy after 6 years. They were easy to work with. The technicians, Cole and Andrew, were on time and finished the job quickly. Mike Clark in the HQ was great and managed the process from start to finish. Overall, great communications

Lisa was a Superstar and provided wonderful customer service. In this day and age age unfortunately bad service is not unusual. It was so refreshing to have Lisa who took extra time, walked us through the process abd then delivered. She waz exceptional and this company stands by their product. Thank you Lisa!!

We had a warranty claim as one of our handles has been having some issues. I reached out and Lisa was wonderful. Within a very short period of time, she had ordered a new handle to be sent to us. Thank you for the quick rescue.
