They did a great job overall. Windows look fantastic and crew were totally professional and polite; a pleasure to deal with! Customer service and response is great. Re: pressure washing of driveway and sidewalk, I did have them return, as there were many spots that did not get taken care of/clean the first time. However, as soon as I pointed that out, they put on me on their schedule to come back and within 5 business days had taken care of the majority of it--used a stronger chemical on the still-dirty areas, and that made a huge difference, especially along the sidewalk. It (sidewalk) is so clean I will be able to seal that now. Probably won't seal the top portion of drive as there are still a few areas with embedded dirt that were missed by the stronger chemical treatment. Will have my husband try spot-pressure washing those few areas. There was a tiny bit of confusion as to whether the front door glass was included in the window washing quote (original quoter said "yes," but actual cleaner said "no." However, in the end the cleaner did agree to clean it. Overall, the driveway looks 10 times better than it did before, and I would use Glass Geeks again!
