We needed new windows, sliding glass patio door, and a new front entry door assembly for our condo. When we got estimates from several window, door, and renovation companies it was difficult to compare apples with apples. Despite the fact that our condo association spells out specific guidelines and requirements for contractors in doing this type of renovation here at Lake Barrington Shores, most of the contractors wanted to do it the way that they have grown accustomed to.

We wanted to make sure that we chose a company that was going to follow the specs and condo assn. requirements and was going to comply with all codes prescribed by the Village of Lake Barrington. We chose to go with Olson Windows & Doors in Barrington. Scott Thorson, sales associate for Olson Windows helped us in choosing the right windows, door options, and style choices that suited our needs and met all of the specifications for the authorities having jurisdiction.

With all of the cooler and wet weather we had this spring we have already noticed a significant improvement in maintaining a steady temperature without having our heat pump having to work overtime. And with these extreme summer temperatures right now our cost savings are already apparent. Our window and door investment choices are paying off. While our quote for this improvement was more than some of the other quotes we received we feel that our choice of Olson Windows was the right one.

Their adherence to building code regulations as well as their complete follow-thru with delivering and installing a quality window and door make them our number one choice for a dependable and satisfying renovation.

Olson windows was a wonderful company to work with. It started with Tony meeting us and giving us a quote. He followed up but no pressure to go with them. He waited for us to decide and followed through the entire way. The workers were also excellent. Came on time every day and completed their work efficiently. I appreciated their professionalism and minimal stress we had to go through. I will definitely recommend them to anyone.

Ivan was my sales guy and he was the best! Great installers too! Very friendly even with my 3 little kids watching their every move. It turned out clean for the front of the house and I will definitely be having them back to finish the last few windows in the house. Services: Installation, Custom windows

We used Olson for our siding and gutters and they did a great job, we really loved the overall look of how it turned out. Had a few hiccups but I have to say at the end of the day, Tony was amazing and took care of the issues. We really appreciate his customer service.

After doing research about window companies I started to think that all the players were bad. Tons of reviews about poor service, poor support and a hard sales pitch. Olson was the only one that didn't have those bad reviews so I went that way. I'm so happy I did! Everything went exactly how they said it would. And the installation team was super competent and super polite.

Best of all there was NO hard sales pitch! We did half the windows in our house in the first round and I most assuredly will be working with Olson to complete the project and do the rest of the windows in a few months.
