Greg and his team were great! Arrived on time, very pleasant and professional. They prepped the rooms and cleaned up, and the windows look fantastic. Andersen is a company we will definitely recommend.

The material that these windows are constructed of is super high quality. The installers dismantled the original windows and installed the Anderson windows in impeccable time and efficiency. They were pros! I said I’m not sure about the price because only time will tell if they are worth the price. The quality seems to be the best material that I want in a low maintenance window but they are quite pricey. If the quality holds up over time, they will be a bargain. Time will tell but as far as customer service, product knowledge, installation pros and work efficiency, this company is great!

We started our adventure with Andersen windows in April, Alon the sales person came out with a great attitude and we decided to go with them, I know for a fact that I requested ROYAL BROWN flashing for the front bay windows because we just had our roof done and the flashing for the roof was brown. He said no problem, we felt good that this small request would be taken care of. Now it comes to the Project Manager to come by and take final measurements. Then he sets up the install date and the team comes lead by Denis. They were great, however I noticed that they were using white flashing around the side windows, then it came to the big bay window that is our eye catcher. They installed WHITE FLASHING, when I asked Denis what happened to my BROWN flashing he showed me the write up that DOUG the project manager wrote up. So between Alon the sales guy and DOUG the project manager, someone dropped the ball. We talked to Doug about it he came out then said let me call the office and talk to my bosses, he called me back and said they would fix it, THAT WAS 3 weeks ago, now I called DOUG last week Tuesday and he said “ they still haven’t fixed it yet?” No DOUG that’s why I am calling you, well here it is Americas birthday today 250 years old and still no brown flashing, not a word from DOUG. Hope this helps future customers make sure you check every step from start to finish. Happy Birthday America !

Just had Richard Powell, Project manager came out to measure the windows and we changed a few things. He explained everything so I could understand. Great guy!
