We were very satisfied with our customer service rep> Marcus McLaren and our lead installer Adam Bautista.

We were not kept informed of when we would be getting our patio doors. They were installed a month after we expected them.

Overall, excellent work done in the midst of confusing weather changes. There was some confusion in getting the install done and the 2 people working on the project did a great job resolving it - checking with me throughout.

Everything was great and too our satisfaction except the crew that installed our upstairs windows did no clean up the mess left on our roof top. I stress that cleanup after the job is an important part of completing the job.

Love our new Windows. We had wood frames before and they were so drafty. Our Anderson window are great and no drafts. Thank you Anderson
