So Happy with our purchase... We purchased our entire houseful of Amerimax energy efficient windows through K & K Klassic Designs. We had been pricing replacement windows through different local outlets, always asking for the identical product so as to compare apples with apples. Ken Logan, owner of K & K had approached our home. We immediately had a good feeling about him and allowed him to do an in-home consult to price out our needs. His pricing was well below the others for the same product. Based on our budget, he made sure we were able to take advantage of factory savings by splitting the order over time . All went smoothly, our installer was premier....neat, clean, efficient and precise. We found the whole process to be a pleasant in home experience with Ken's patience, good communication and most of all fairness and honesty. We are extremely satisfied with the product. It has cut down on noise, transmission of cold is greatly lessened and there are no air leaks. The fact that they all tilt out for easy cleaning is the cats pajams! Don't let the fact that he is a small business fool you...he delivers big on savings and service!!! We would highly recommend.

Had windows replaced on our Southern exposure in 2014. Ken was great to work with offering me great value and quality. His installer was top notch. We had a warranty issue with an awning window that was not locking properly in one corner and Ken had Amerimax come out to adjust the window ASAP! The noise reduction is noticeable in our bedroom as is the ambient room temperature. You will not regret the service and quality offered by Ken and his company.

I had three companies come out for an estimate and Ken came in FAR below the others. I am so pleased with these windows! The install was very fast as well.

They just completed replacing my windows and doors last weekend. They have a great product at a great price and most of all trustworthy.

We were very impressed with the product and service around the installation of all new Amerimax windows and sliding glass doors in our Highlands Ranch, CO residence. We highly recommend Ken from K&K Klassic Designs and the installation team of Bill, Troy, and Chris. The product has proven to be a definite improvement to our house. The draft around the windows and sliding doors has been entirely eliminated. The windows look wonderful adding a noticeable visual advantage over the replaced windows. The French door design of the sliding glass doors definitely improve the physical appearance of the rooms where they are a part. We cannot speak highly enough of the installation team of Bill, Troy, and Chris. They were incredibly professional and masters of their trade with their abilities to remove and install all our windows and sliding doors. While the job could have taken up to 3 days, they did it in two. On both days, they arrived during the time frame promised. Then when they arrived, they were cordial… but they were focused on working. An incredible work ethic portrayed by all 3 that made us happy they were working on our job. Their efforts to clean up after themselves were extra-ordinary. On both days, the amount of clean-up we needed to complete was basically non-existent. The same goes with the minimal amount of ‘touch up painting’ required after the windows were installed. While the windows are definitely new, the workmanship made the windows look like they’re part of the existing house structure. Anyone would be fortunate to this installation team work on their home. Finally, working with Ken was a definite asset to the process. He worked with us from beginning to end regarding scheduling, explaining options, creating an acceptable contract, and taking payment as agreed. He came to us recommended by a neighborhood workmate, and we would recommend him to anyone seriously interested in replacing their windows and sliding glass doors. Happy Customers – Brad and Diane

We had 10 windows replaced by K & K in our home in Bailey, Colorado. Before the windows were replaced, we had been dealing with home's original windows (all single pane). The windows were often stuck shut, cracked, and very inefficient. We called a few of the bigger window companies to get replacement estimates, and all the prices that came back were way out of our budget. We called Ken after seeing a Facebook post and we received an estimate that was dramatically lower in price, and he was able to start the installation within two weeks. The installers that showed up to our house were local, very professional, quick, and did great work. The windows look great overall, and we are very happy with the job done by K&K. We are also looking forward to a much warmer winter!

I met Ken in 1998. He was recommended by a friend who had windows and siding installed by him. I was interested in windows only during this first contact. He came to the house and explained the options available in an understandable way that helped me make decisions on what type of class and style of window would work best for my situation.

After that job I recommended Ken to co-workers and friends who wanted windows, siding and gutters over the years. All of them have been happy with his work and I know they have also recommended him to other people.

In 2007, I had Ken install siding, windows, fascia and gutters on the home I currently live in. Again I was very satisfied with the quality of work done by his contractors. This year, (2014) I needed to replace eleven large fixed windows that are part of a passive solar system in my home. I got several estimates along with Kens’ to compare prices. I found, with no surprise, that Ken had the best price, my experiences with him left no doubt, that I would be satisfied with the work done. He also did a custom “wrapping” job on the wood base below the windows so that I will never have the unpleasant task of scraping, sanding and painting again! The wrapping matches the siding trim put on back in 2007 and adds a nice finishing touch to the job.

During this process, I sent Ken to one of my neighbors who was thinking of putting siding on his house and detached garage. Ken visited with him and ended up doing that job as well!

Purchased our windows and installation with K&K Klassic Designs; the price was quite a bit lower for similar or same windows through other companies. One of our windows was a custom bay, 1 picture and 2 casement windows) which was built onsite and came out great. Overall we are very happy.

We just moved to Bailey CO in July and needed to replace all windows in our new home. K&K did a beautiful job all in one day. We love the windows and want to thank Ken for taking such good care of us!!

We are 100% satisfied with our service and install with K&K Klassic Designs. Ken was very honest and fair in the pricing. They stand by their word and provide the best service we could have asked for. We are now having a second home window install. Thank you K&K Klassic Designs!

Ken came out, evaluated my difficult install, gave a great demonstration. He was fair and honest throughout the process and destroyed the competition on pricing, but did not skimp on installation. I had a very minor concern after install, he was out the next day to fix it without complaint. Completely satisfied, would use again and recommend.

11 years ago we replaced our origional 1975 aluminun windows and sliding door with new lo. E 270 + argon gas Amerimax windows and sliding door through K&K Klassic Designs, Inc.
Our home was immediately much quieter, we could no longer hear the dogs barking at night next door and living close to Wadsworth Blvd. we couldn't hear the traffic especially the ones stopping and starting at the stop light at W. Peakview Ave. any longer. The freezing drafts during the winter were also gone.
We have had zero problems with the new windows & sliding door, no broken seals and no broken latches, hinges or rollers.
We are totally pleased with the product, price and the service.

K & K Klassic Designs was recommended by a friend. I called and met with Ken Logan. In a very friendly yet professional way, Ken listened to my needs and clearly explained options and pricing. I ordered a total of eleven window replacements. Eight of them were done promptly and perfectly. I delayed the installation of the last three due to a family issue. When the time came to install the three large windows, Ken worked quickly to secure the installer who did an excellent job. As I consider replacing more windows in my home, I definitely would call Ken of K & K Klassic Designs again. I am very pleased with the service he provided and the product he sells
