“Coastal Shield Windows did an outstanding job on our back picture window replacement. An unexpected accident forced us to look for a quick quote and fast work. From my first outreach, Andy went out of his way to come onsite and look, providing excellent recommendations for a replacementl He kept us informed every step of the way. The communication was thorough and professional, and the craftsmanship speaks for itself—the job was done beautifully, and the window looks amazing. Couldn’t be happier with the final result. Plus, the quote was competitive and fair. Highly recommend Coastal Shield Windows for anyone looking for quality work and great service!”

“We recently had new windows installed by Coastal Shield Windows, and the difference is incredible. My thermostat is set at 66°, and it’s 71° inside the house — that says everything you need to know about how well these windows perform.
The quality, efficiency, and craftsmanship are top-notch, and you can immediately feel the improvement in comfort and temperature control. If you’re looking to improve insulation, energy efficiency, and overall comfort in your home, Coastal Shield Windows absolutely delivers. Highly recommend!”

We love our new door from Coastal Shield. We had an old and rotting solid door with sidelights replaced with a 3/4 windows door and sidelights and it looks so much fresher and more elegant. Andy helped us select the right door, he and his team did a great job with installation. Everything went smoothly, cleanup was outstanding and terrific customer service and communication throughout. Appreciate. Thank you.

Andy and his crew were the ultimate professionals. Their quote came in well under several other bids. Communication was easy. Moreover, they worked quickly and thoroughly, left things in order at the end of each day, and went above and beyond to take care of all the unknowns that popped up. The new windows totally transformed our house. We could not have been more pleased and would recommend Coastal Shield Window to anyone in the market for windows/ awesome customer service.

Replacing our home’s 28 year old original aluminum windows was long overdue. Coastal Shield was very helpful in providing options that fit our taste and budget. Offered creative and aesthetic ways to reduce total window count to save costs. Very pleased with the impact rated windows and end result. Highly recommend!
Paul

Last spring we realized we need to replace our existing windows. All 75 of them. After obtaining several quotes, we decided to hire Andy Yagecic from Coastal Shield Windows, LLC. He did an outstanding job—always punctual, professional, and respectful of our home. He consistently left the work area spotless and approached the project with great care and attention to detail.
We highly recommend Andy to anyone in need of window replacement or home improvement services.
Mary

We recently hired Andy for a window replacement project at our home, and I couldn’t be more impressed with the results. We had a unique situation with two “interior” windows created after remodeling our porch into living space—he came up with a smart, cost-effective solution that fit perfectly without breaking the bank.
On top of that, he replaced five other windows where the casement crank-out mechanisms had completely corroded and failed over the years. His pricing was competitive from the start, and communication was excellent throughout.
The installation day was seamless—the crew was professional, efficient, and left everything spotless. The new windows are clearly high-quality: they operate smoothly, and look great.
Andy earned our trust completely, and we’ll definitely call him first for any future window needs. Highly recommended!

Coastal Shield Windows (Andy and his team) did a fantastic job on the window project on our back porch. Andy gave great recommendations in the very beginning and was a great communicator throughout the project. Trim work is beautiful as are the windows! We are very happy with the end result. Competitive and fair pricing too.

We replaced a large picture window in our living room. Andy kept us well informed throughout the whole process. The crew arrived on time and the new window far exceeded our expectations. Andy is a local small business owner who gives top notch personalized service. He even found other possible problem areas for us to be aware of during replacement of the window.

Fantastic company! Our sliding glass door broke on a Friday afternoon and Andy came out first thing Saturday morning. He was super responsive and communication was great. In our case, he was able repair the door and save us a more costly replacement. We will definitely use Coastal Shield Window again in the future and would highly recommend them to anyone!
Meredith

Very happy customer, from the initial consultation through the completed project. We had several high impact windows replaced because of botched work by prior contractor (before we owned the house). Andy is knowledgeable and made several good suggestions. Pricing was very competitive. The actual installation was quick and efficient, with daily cleanup and debris removal. Recommend with no hesitation.
