Why Homeowners Along the Carolina Coast Choose OKNA
OKNA windows are a strong fit for coastal South Carolina because they’re made to perform in conditions like these. Their multi-chambered frames help reduce heat transfer, which can make a real difference during long, hot summers. They’re also built to resist the moisture-related issues that often affect lower-quality windows over time, such as swelling, warping, and extra wear.
That kind of durability matters near the coast. With weather-resistant materials, UV-protective glass, and construction designed to withstand humid, salty, and windy conditions, OKNA windows offer homeowners a more dependable long-term option. The result is a window that not only looks good, but also works hard for your home season after season.
Window Styles Available Through Contract Exteriors
OKNA windows come in several styles to match how each room functions and your home's architecture:
Casement Windows: Hinged and crank-operated with strong seals and good ventilation control
Double-Hung Windows: Both sashes open independently for practical living spaces and easy interior cleaning
Picture Windows: Fixed-frame windows maximize glass area and unobstructed views
Sliding Windows: Wide, clean sight lines paired with smooth operation; ideal for rooms with panoramic views
Awning Windows: Hinged at the top to open outward, letting air in during rain
Bay & Bow Windows: Multiple angled units creating curved projection and expanded interior space
Glass Options & Upgrades Worth Knowing About
SunSeal Glass
SunSeal Glass reduces solar heat gain, directly affecting how hard your HVAC system works during warm months. It also filters UV rays, protecting interior furnishings and surfaces from fading. For west or south-facing exposures in Myrtle Beach or Charleston, it's a meaningful upgrade to consider. The energy savings often offset the upgrade cost over time, especially in high-heat seasons.
Additional Glass & Performance Options
Depending on which OKNA series you select, additional glass configurations and performance options may be available. Your consultation is the right time to discuss what fits your home's orientation, budget, and performance goals.
The OKNA Series: Matching the Right Product to Your Home
OKNA offers several window lines, but most homeowners end up comparing the 600 and 800 series. The 800 series is the more robust option, with upgraded construction and stronger overall thermal performance. The 600 series is a more budget-friendly alternative that still delivers reliable performance and durability.
Both are well-suited for coastal conditions. The right choice comes down to how your home is exposed, how long you plan to stay, and how much performance you want to build in from the start. A proper consultation helps you choose based on those factors, so you’re not overpaying for features you don’t need or cutting corners where it actually matters.
What the Installation Process Looks Like
Window replacement involves more than swapping glass. Preparation, fit, and details around each opening affect long-term performance and weather-tightness. Our process follows a 60-step internal workflow designed to maintain consistent quality across every project from start to finish.
We handle full replacement only, including removal of existing frames and proper preparation of the opening. When on site, our focus is on proper preparation, correct installation, and clean surrounding work. For details on what to expect, our window installation day prep guide walks through pre- and during-installation considerations to help you prepare your home.

Common Questions About OKNA Window Installation
OKNA sits in the premium tier of replacement window manufacturers with multi-chambered frames, quality hardware, and extensive glass options. Build quality is consistent, supporting both performance and long-term durability. We've chosen OKNA because it supports the workmanship standard we deliver.
We handle complete window replacement, including removal and full installation. The 7-year workmanship warranty covers our installation work, giving you recourse if something isn't right.
Our 7-year workmanship warranty applies to installation. If our work causes a problem, we address it. The manufacturer's warranty on OKNA windows covers the product separately. Both warranties apply after installation is complete.
Coastal South Carolina conditions, including sustained humidity, high heat load, and occasional tropical weather, stress windows more than inland climates do. Windows with stronger weather resistance and better thermal performance hold up better and cost less to maintain. We factor in your home's location and exposure when recommending products.

Outstanding Reviews
Brooks was my contractor on the project. He was awesome! He was there with me every step of the way! Eugenia was very helpful in the office and assisted me in getting the HOA approval. Jason explained the warranty process and even brought me a cake!
Everyone we came in contact with was very cooperative and easy to work with. It was a pleasant experience from the first online chat. They listened to us and helped solve any issues we were concerned about
Wow, this company goes above and beyond. From the very first reach out to the very last interaction once the job was completed. Everything was done first class. The quality of work, the constant communication and level of service was like nothing I’ve ever experienced with any contractor. I priced out a couple different contractors compared to contractor exteriors and I will tell you I would have paid more just to have this experience with them. I had Jonathan as my project manager and he was exceptional.
Very happy with our new Timbetech front porch deck and steps with AZEK facia and risers. Everyone at CE was responsive and very professional explaining every step in detail! We have several homeowners in our community who have already asked for contact info info. Jonathan is a very good project manager and ensured we were satisfied with the quality, cleanliness, and appearance of our new front porch! Thank you!
In choosing a company to replace our deck, we researched and decided to use Contract Exteriors. We definitely made the right choice. We are very pleased with the results. Special thanks to Brooks, our Project Manager, who kept us updated and informed everyday.
Contract Exteriors did a great job for me. The entire group was very responsive, and my deck project turned out fantastic. My project, as all projects, had some surprises that were handled professionally and promptly. Randy, Brooks, and the office staff were great throughout the process. They proactively kept me informed on the status of the project. I never had to call twice to get a question answered or ask for an accommodation.
We couldn't be happier with contract exteriors and the job they did. Our beach house looks brand new with the new Hardie board and white trim. EVERYONE was friendly, well mannered, professional, and was always ready to answer any questions that we had. Miguel and his crew did an excellent job. Brooks the project manager was wonderful, and also Chad who helped us from the very beginning, also the girls in the office. We would not hesitate to use them again.
This company did an amazing job on my siding project. From start to finish they were very professional, helpful, and on time. Eugenia clearly communicated the whole process to me before they even started the project and Brooks was always available to answer my questions. He even came and ensured the cleanup was perfect and finished up the exterior lighting. Even after the project was finished this company ensured communicated to ensure everything was perfect. Super pleased. Thank you!
Everything about this group was extremely professional. Renovations can be challenging but they carefully made sure that their products and our original structures fit together seamlessly. We are truly looking forward to our new elegant deck that will be essentially maintenance free for many, many years. We will definitely use this company for future projects.
Matt Kuzdrall made our whole experience of purchasing two new roofs for our buildings at the Children's Recovery Center so easy. Matt was professional and had all the answers to any questions we had. He has followed up since our new roofs have been installed to make sure everything is still great. Matt is awesome and I would recommend him to anyone I know looking for a new roof.
