Window Replacement Contractors in Crystal Lake, IL

"Tom was extremely professional, careful, fast, and timely in his work. He responded promptly to my request for an estimate. Provided a great solution to the problem I was having. And was able to get the work done in a tight time frame. His price was very reasonable. He went above and beyond to improve the flashing before installing the new siding."

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

"Very thorough and very professional work."

"Renewal by Andersen provided an excellent experience from consultation through installation. The entire process was professional, organized, and far less stressful than I anticipated. The team communicated clearly throughout every step, arrived on time, and completed the installation efficiently while keeping everything clean and orderly. The quality of the windows is outstanding, and the difference in appearance, comfort, and overall feel of the home was immediately noticeable. I especially appreciated how thoroughly everything was explained, including the installation process and maintenance tips after completion. A special thank you to the consultant for being knowledgeable, patient, and professional during the consultation process. There were no surprises, and the entire experience felt honest and well-managed from beginning to end. I would highly recommend Renewal by Andersen to anyone considering window replacement."

"In addition to the installation of a light, they also installed a medicine cabinet. Both needed some additional work- installation of a junction box and hole needed in a plastered wall; filling in of extra space around medicine cabinet rough opening. They also replaced some wood trim around a large tool shed. Job came out great. They were professional and conscientious to take care within my home. Tom and Mike did a very nice job."

"We had a total of 7 windows plus a huge bay window replaced. The entire crew was professional, efficient and knew exactly what they were doing. They completely redid the whole framing for the bay window, including all the construction on the outside of the house. When it was completed, not only did it look like it was there the whole time, but even matched the shingles on top of the frame to match my house. They answered every question and made sure I was satisfied before they left. HIghly recommend!"

"They respond very promptly. Evenly priced. Very personable and easy to talk to."
