Rod was very clear and professional explaining different options we got. He was very happy to answer any questions we had. The price is reasonable.

Wonderful! I had a great customer experience dealing with Diana. She was thorough, knowledgeable, and very descriptive in the estimates. She would always be open and willing to make any change I wanted and send back the updated estimate. The estimate had all the explanations to the T for every window. Overall, I am very happy with the Milgard windows that Diana and her team at Windows Only installed at my home.

We replaced all of our windows and 3 sliding glass doors, and our front door. We were very satisfied with Windows Only. They did an amazing job. The price was excellent and the service was outstanding. We would highly recommend them.

This is the second project I have had Windows Only complete at my house. The first project I had received multiple bids to replace several windows. Windows Only beat out their competition on price and I'm sure they also beat them on the quality of installation. The second project was a sliding glass door and window, I didn't even entertain a second bid, I went straight to Windows Only. I have to say that Rod is fabulous to work with, and really listens and remembers his clients requests. Gordon who installed my sliding door and window is a true craftsman. Gordon had to deal with several challenges on this project, and handled them with a skill that most people envy. The job site was so clean I couldn't tell Gordon had even been there. I can't give enough praise, thank you Windows Only!

11 windows and a new sliding patio door complete in just two days! Gordon was courteous and clean. He even spotted a couple of slightly bent screens and recorded them on the spot! Everything looks great!

Windows Only was fantastic. We worked with Rod (sales) and Gordon (installation), and both made things so easy for us. The price was below another local company, and they did a great job. Rod is especially knowledgeable, helpful, and there for you every step of the way, and after. Rod goes above and beyond to make sure you are 100% satisfied. I will recommend Windows Only to anyone needing windows.

Great responsiveness to both get a quote and after we had contacted the work with them. Rod was a pro who walked us through the options and offered options clearly with the pros and cons laid out. Gordon was our installer and he went above and beyond during the actual installation. Our siding was shrinking away from the windows and was going to cause a really wide caulking bead to fill. Gordon offered to trim the siding back to the widest gap and replace the trim with a wider option to fill. The new windows look great, and the whole thing was done for a very competitive rate.
