    Very friendly staff, showroom, professionally done. All questions were answered thoroughly. Our cabana series glass is just what we wanted to enclose our screened lanai, love the extra room. The finished product was fairly priced and very well done. Only issue we had was all dates estimated were very low, four visits to office to encourage appointments and procedure to keep going. Mistakes, during ordering, turned our 7 to 8 week estimate into 11 then 15 weeks.

    Custom windows provided window cleaning after installation of new lanai windows. Cleaners did a great job. They were thorough, quick, and very curteous.

    The thing we didn’t care for was our old enclosed porch was torn down for 5 weeks before the installation could take place. We had a tv, mini split and a fan that all had to be covered by 2 old ladies up on ladders. Two suggestions- either help cover those items but then also figure out a better plan than 5 weeks before installation takes place. Not happy and slightly agitated. Also this is our 2nd porch enclosure with your company.
    Response from the owner:We appreciate your feedback and understand it's not desired to have a already enclosed lanai open while custom sized new products are manufactured to fit your newly designed layout. Using our many years of experience, we assess each project to determine the best steps to provide each customer the best finished results. These expected processes are discussed upfront and openly during the designers consult and at time of initial measurements. We truly want the best outcome for each customer. We even offer draping screens around all openings to help limit wildlife from entering the area during the product manufacturing and delivery times. We are sincerely sorry you feel we missed the mark for your specific situation as most customers don't cover ceiling and high mounted fixture and items.

    We called Custom Windows to have our lanai windows and screens cleaned. Each time they have cleaned our windows, they have been extremely good, very professional and friendly. We love the work they do…especially that we don’t have to do it.

    Custom Windows and exterior design is one of the best businesses we have dealt with while living here in The Villages. Added glass sliding doors to lanai, They show up when they say they will finish the job when they say they will and give you quality products. we couldn’t be happier with our choice in using this company. Two of our neighbors recommended them and they hit the nail on the head. We also highly recommend them.
    Response from the owner:We are proud of our staff and our products. Thank you for sharing your experience.

    Remodel of lanai was excellent. Kyle and crew did an awesome job with impeccable attention to detail. Window cleaners excellent as well. I only wish the storm door opened the way the previous one did. This one opens the opposite way but it usable as is.

It brings us joy to know official building inspectors comment about how well they view our work. Again thank you. We expect you'll be able to continue enjoying your Lanai for many years to come.

    I had the most satisfying experience from a window and door company that I have ever had. From the time that I visited the place of business. Custom Windows and Doors were so eager to help with my project. Custom Windows and Doors did an outstanding job and I will be doing more business with them in the near future. Custom Windows and Doors are a definite asset to the community of THE VILLAGES. Mike Culpepper

    We started this process in June of 2025. It has just been completed this month FEBRUARY OF 2026 so approximately 8 months. This company has been very responsive to issues with quality fixes. These issues were primarily due to supplier quality problems. Hopefully these issues will not be persistent for Custom in the future. Thanks to Custom’s team in working through the problems.

    Response from the owner:Thank you for the feedback and we appreciate you still giving us a relatively High star count. Unfortunately some of the situations with the manufacturer can sometimes prolong job timelines and isn't what we desire with our reputation. We continue to stand behind the product to provide quality and we sincerely hope that you're now able to fully enjoy your Lanai and relax with a "good life" feeling.

    We just had our Iris lanai enclosed by Custom Windows and I have to say they were exceptional to deal with from the beginning of measuring to the exact date of installation they said they would. The team who ripped out the old framework to installation of new frames and stackable doors was perfection. A special shout out the man who had to had to redo all around the framing with stucco. He was an artist- you cannot even tell it was redone. TY TY. The painter was so meticulous as well and the ladies who cleaned the windows weee super professional and brought towels to stand on so no mess inside. Thank you to the fabulous team. We use the lanai every single day now.
    Response from the owner:Thank you for this acknowledgement of our efforts. We appreciate your choosing Custom Windows and Exterior Designs for your lanai enclosure beautification project.

    Window & Sliding Glass Door FAQs for Dunnellon Homeowners

    Choosing the right Window & Sliding Glass Door begins with understanding your options. Here are a few questions Dunnellon homeowners often ask before starting their project.

    The best windows for Dunnellon homes depend on your priorities, such as energy efficiency, storm protection, airflow, and the type of space being upgraded. Insulated Low-E windows are a strong choice for comfort and energy performance, while wind-rated options can provide added protection during severe weather. Custom Windows & Exterior Design offers multiple window series to match different performance, ventilation, and design needs.

    Impact windows and hurricane-resistant windows are often used interchangeably, but they are not always exactly the same. Impact windows are designed with laminated glass that helps resist breakage from flying debris, while hurricane resistant windows may also refer more broadly to products engineered to meet specific wind and storm-performance requirements. Custom Windows & Exterior Design can help you choose the right option for your Dunnellon home.

    Yes. Low-E windows can be especially valuable in Dunnellon, FL because they help reduce unwanted heat transfer while allowing natural light into the home. This can support better indoor comfort and energy efficiency, particularly during long periods of warm weather and heavy air-conditioning use. Custom Windows & Exterior Design offers window options with Low-E glass for homeowners looking to improve year-round performance.

    For a Dunnellon home, look for sliding glass doors that balance durability, energy efficiency, smooth operation, and storm protection. Features such as insulated Low E glass, quality frames, secure hardware, and appropriate wind ratings can improve comfort, safety, and long-term performance. Custom Windows & Exterior Design offers multiple sliding glass door configurations to fit different homes, openings, and design needs.

    Yes. Energy-efficient sliding glass doors use features such as insulated glass and Low-E coatings to help reduce the amount of outside heat entering your home. In Dunnellon, this can help interior spaces stay more comfortable and reduce the workload on your air-conditioning system. Custom Windows & Exterior Design offers sliding glass door options with insulated Low-E glass for homeowners looking to improve comfort and energy performance.
