A selection of 287 homeowner reviews:
“Lake Cook Exteriors was absolutely excellent. We had siding, gutters, and downspouts installed. They were very friendly and very responsive, both in the initial call and with scheduling. Afterwards, I had a question, and the owner got back to me. It was service way above and beyond. I would give them an A+.”
“They were on time, prompt, and professional. They had it up in no time, and the product is doing fantastic. I'm happy. They're A+ all the way down the board.”
“They replaced our gutters. They were attentive and prompt, and they did a good job. They're A+. I would use them again.”
“They had a quality product and excellent customer service. They did gutter installation for me. I'd give them an A.”
“They were very professional and did their job very well—A+.”
“They do excellent gutter work with no complaints.”
“They did a great job. They put gutters on the house. My overall experience with them was excellent.”
“They were excellent. They were really good. The guys were really nice. They came and knocked on my door when they came and when they were getting started, and then they said goodbye when they were done. They did a really good job. We have not had any water in the basement since, and they did a really good job with the follow-up. The only thing I didn't like is that, afterward, we got a couple of advertisement emails from Lake Cook Exteriors for some other things they do, like windows or doors or something, and I definitely didn't sign up for that. Nobody needs more email advertisement. Based on my experience, I'd give them an A overall.”
“They did new gutters for me. I enjoyed working with the sales rep. He came out several times to address some of my questions and concerns. He was very professional. They were A+.”
“They did gutters and gutter guards for me—leaf guard things. They were very efficient. They got the job done. I haven't had any problems with them. They cleaned up after themselves. They were in and out. They didn't bother the wife or anything like that, so they were very good. They were A+. It was fine.”
