This Series offers all the benefits you come to expect from vinyl windows with a variety of options to make your home energy efficient while enhancing its beauty. Since all OKNA products are custom-made, you can be sure of a perfect fit, which translates to savings on time and labor during installation.
Instead of a window that looks like a vinyl replacement, Starmark Evo will match your original architecture with the look and feel of your original wood windows. We constructed the Starmark Evo Window to authentically represent a traditional wood window. The smallest details, such as the rounded beveled edges of the glazing bead gives a nod to the classic traditional look.

Just had a sliding patio door installed by Rodrigo and Marshall. They were awesome, insuring that the job was done professionally! They went above and beyond in their work so that more door was functional and great looking. I highly recommend asking for them to do your install.

Pinnacle did a great job replacing 6 of our windows. They did a great job installing our new high efficiency windows. They were courteous, quick, and very reasonably priced. I would highly recommend them and we would definitely use them again. Service: Double pane window installation & replacement

Giving Pinnacle Windows a 5/5 would be still somewhat under-rating them. Lee Fuller (owner) knows his game and focuses on quality products and a solid installation team. A HUGE shout out to Steve and Austin (installation team); not only were y'all personable and funny, you were very professional. You exceeded our expectations, when you went above and beyond your tasks.

And Nancy, THANK YOU for being such a great amicable coordinator. We're glad and proud to be a part of the Pinnacle/Okna family! P.S. For what it's worth: we interviewed 15 local window companies, before deciding on Pinnacle

I love my new windows and sliding glass door from Pinnacle of Woodstock. And I was very, very happy with the installation! The workers were fast, yet they paid close attention to the detail of what they were doing, to make sure they did it right. They were polite and professional but they didn't "chit-chat, " they just worked. I got 7 windows and a sliding glass door.

I don't feel the cold as much anymore and it's so quiet in my house now! I didn't realize how much I was hearing through my old windows! The sliding glass door opens and closes so smoothly, with a soft "shhhhhh" sound. And it has a sliding screen door that works just as smoothly! Such a pleasure, after all these years of fussing with the old one!

Not professional! I had heard good things about Pinnacle so I decided to get quote to replace my windows and possibly my doors. I received a called from a gentleman from pinnacle later in the evening after an morning email dialogue with a person from pinnacle. As we began to work out scheduling, he asked me if my wife was going to be around for the appointment and I said no, due to the fact that she would be on assignment in California.

And not only that, the home is in my name solely. He proceeds to get nasty with me, tells me, "I likes getting a check so if your wife will be there then I'm going to cancel the appointment" and he hung up on me. I was dumbfounded. But what he didn't realize is that I had the phone on speaker due to the fact I was taking my Wife to the airport. My wife and my Aunt heard every word he said and they were just as dumbfounded. Pinnacle really screen who they have calling and setting up appointments because this call was totally unprofessional. Well, there are Plenty of great window companies to replace my 23 windows. On to the next one.

My first house I made the grave mistake by using Window World for a window project, needless to say the experience was far from memorable. Determined to NOT make the same mistake on our new house that came with wood builder grade windows I entertained quotes from 4 different companies. All had the typical song and dance from a sales guy, but John F. was the only guy that was not pushy.

He provided the quote in a timely manner and left his contact information and never heard from him again. A year later we pulled the trigger and the original quote was honored, especially during the start of the pandemic when prices may have changed. Lead time was long, but expected, but the estimate was accurate. The install team was a father and son team and let me say that they were fantastic. Steve and Nathan were polite, careful, precise, and installed the 25+ windows with care.

They took care of any wood rot that was discovered during the removal and let me know where it was discovered and advised us the best way to proceed. There was no sloppy cover ups (Window World). I would recommend Pinnacle Window and Siding of Woodstock to anyone looking for a trusted company for their project.

Dennis and his team at Pinnacle Windows were awesome! They were courteous, kept me updated on progress during Covid induced manufacturing delays, and their installation team was the best I have ever had. Not to mention the windows which are beautiful! We liked them so much with the first round of replacements, which included a custom palladium over our front door, that we are replacing the rest of our windows along with 3 French doors with Pinnacle. I highly recommend them!

Our experience with Pinnacle just could not have been any better. From the very first contact with John and a personal call from the owner, to the outstanding and above and beyond craftsmanship/work ethic/cheerful attitudes (especially on a 29degree day) from Steve, Jason & Nathan made for a perfect experience for first time window buyers! We are THRILLED with our new windows!

Our custom windows from Pinnacle are even better than we envisioned. Our home looks amazing and we are so pleased. The customer service was excellent. The old singled pane wood windows were damaged, so repair work was needed before replacing the windows. Then they capped with the repaired wood brick mold, window seals, and window nose. No maintenance now.

Many of our windows went from a pair or three multiple windows to single large picture windows. Steve and Jason, the installers, were master craftsmen, trustworthy and they cleaned up at the end of each day. Two of our best friends from church recommended this company to us after their excellent experience. We will be passing on the same recommendation to other friends. Nancy, who runs the office, was a delight to talk with and kept us well informed during the whole process.

She was very patient with our many shopping decisions. Our comfort level changed drastically. We don't feel a draft around our windows anymore and have noticed our home is quieter. Many companies we talked to each sell the same exact product, but Pinnacle's variety of replacement window manufactures, quality, and price for the money was better than competitors.

We went with Okna 500 series. The owner, Lee Fuller, was helpful in answering our many questions and was very available. He was a please to talk to and very concerned about our total satisfaction. He even called after the job was complete to see if we had any concerns. We appreciate working with such a professional company with a high-quality products and a capable, personable team.
