What Our Customers Are Saying About Us!
Lou Tomassone2025-01-06Trustindex verifies that the original source of the review is Google. Fair Price and no issues with any touch up items i needed complete. I would recommend them to anyone looking for new windows. Greg Leithauser2024-12-13Trustindex verifies that the original source of the review is Google. Koehler replaced our windows 2 years ago. A problem with one of the windows came up and I contacted Toby from Koehler Jacksonville. He sent a technician out immediately and fixed the problem with no financial requirement. Great service, standing by their product. Courtney S2024-10-27Trustindex verifies that the original source of the review is Google. I called around to 15 different companies to get a sliding screen door installed. All of which were very unhelpful because I didn’t purchase the sliding glass door from them (I bought the property as a new build). The owner at Koehler called me back and took the time to explain to me what I needed to do in order to get a sliding screen door. Although he wasn’t a seller of the specific brand of glass doors I have installed, he took the time on the phone with me to explain what I needed to do in order to get the sliding screen door. He even went as far as recommending another local company who does work with my specific brand of glass doors. I would highly recommend Koehler on customer service alone. For any future needs that I may have I will certainly be calling them. Nancy Crawford2024-08-29Trustindex verifies that the original source of the review is Google. The entire personnel at Koehler Homes was pleasant, knowledgeable, and professional from beginning to end. The windows are beautiful and have helped the efficiency of the upstairs a/c greatly this summer. A job well done. Anthony M.2024-08-27Trustindex verifies that the original source of the review is Google. I've used Koehler for two different home projects. Highly recommend their services as they do phenomenal work. Kelly Nunn2024-08-27Trustindex verifies that the original source of the review is Google. Easy smooth experience, Toby was very helpful at every step in the process! Joseph Hill2024-08-27Trustindex verifies that the original source of the review is Google. I'm very satisfied with the windows and door I had done. Julie2024-07-25Trustindex verifies that the original source of the review is Google. Very easy to work with this company. Excellent communication throughout project. Site prep and clean up complete. Would highly recommend. Te Bo2024-07-21Trustindex verifies that the original source of the review is Google. This is 1 of the best things I have ever done to improve my current home and my way of life. I've given everything time to settle in and me get used to any changes in inside temps and the electric bill. Im happy with both. The process was fairly easy, the timeline was reasonable, the estimator gave a fair price right away=he didnt start at an outrageous price only to go back and forth to get down to a lower price that was still high, and the installation was great. The price was a bit more than I expected but much less than other companies I got estimates from. I suppose the other estimators saw an elderly frail Woman and thought hey-we can make a mint off this one. I am no pushover! My ex was a GC and I know about owning homes, the repairs needed and the costs. I have owned & repaired homes for almost 40 yrs. Cory did not treat me that way. He was quick and gave a fair price to start. Overall I am very happy. The noise level has been drastically reduced. I live around some very LOUD people, and at all times of the day and night, so this advantage is Great! There's little shade on my house & the amount of heat from the Florida sun has also been Greatly reduced inside. What a blessing. I have a few more windows to replace and I wont even call anyone else but Kohler now...Thanks and hey-I want a discount for being a return customer. :):) JIM MANGUS2024-07-17Trustindex verifies that the original source of the review is Google. THEY DID WHAT THEY SAID AND THERE WERE NO PROBLEMS.

Frequently Asked Questions about Window Installation
How long does the window installation process typically take?
Most installations are completed within one day. However, the exact duration can depend on factors such as the number of windows, their style, and any special preparation required at your property.
How should I prepare my home for window installation?
To ensure smooth installation, we ask that you remove curtains, blinds, or any window treatments beforehand. Additionally, please move furniture and valuables at least a few feet away from the windows, giving our installers clear access.
Will new windows help increase my home’s value?
Definitely. Installing new, energy-efficient windows can significantly boost your home’s curb appeal, reduce energy costs, and ultimately enhance your property’s resale value, making it a worthwhile investment.
Is window installation messy, and who handles cleanup?
Window installation can generate debris, but our professional team always ensures a thorough cleanup after installation. We remove all debris, old window materials, and packaging, leaving your home clean and tidy when the job is done.
