Premium Window & Door Installation for Coastal South Carolina Homes
Quality OKNA Windows and Doors, professionally installed to elevate your home's comfort and value.


Professional Window & Door Installations in South Carolina
Your windows and doors do more than complete your home's appearance—they protect your family, improve energy efficiency, and provide lasting security against the elements. In South Carolina's coastal climate, where heat, humidity, heavy rain, and salt air are a constant, choosing high-quality replacement windows and doors is one of the smartest investments you can make.
Older windows and doors often allow drafts, moisture, and outside noise into your home while forcing your HVAC system to work harder. Whether your windows no longer operate smoothly or your doors have become worn and inefficient, outdated products can impact both your comfort and your monthly energy costs.
Contract Exteriors makes replacing your windows and doors simple with premium products designed for long-lasting performance in coastal environments. As an OKNA Certified Installer, our experienced team installs energy-efficient replacement windows alongside beautiful entry and patio doors that enhance your home's security, comfort, and curb appeal. From Charleston to Myrtle Beach and throughout the South Carolina coast, we'll help you choose the right solutions to protect your home while giving it a fresh, updated look.
The Benefits of Investing in a Professional Window and Door Installation
Energy Efficiency
Modern OKNA windows insulate against South Carolina’s humid summers and mild winters, helping you maintain indoor comfort while lowering energy bills.
Noise Reduction
If you live near a busy road, golf course, or beachside nightlife, new windows can keep unwanted noise outside where it belongs.
Durability
Our window systems withstand the challenges of salty air, high winds, and heavy rain. Built to withstand weather-related wear, they provide you with peace of mind year-round.
Easy Operation
Say goodbye to the struggle of stuck or warped windows. OKNA windows glide smoothly and lock securely, making everyday use effortless.
Increased Home Value
Beyond comfort, replacement windows improve curb appeal and marketability. Whether you’re planning to sell or stay put, they’re a smart investment in your home’s future.

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.
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.
