I read the other review on Ellis Enterprises. I am shocked. This was not the treatment I received. I made an appointment for an estimate - also a hillside house with 3 stories. He arrived on time and called for some further directions because the house was a little hard to find. He gave me a very reasonable quote - similar to others I had received. I signed the contract and scheduled a date/time. The workers showed up exactly at the right time, did a prompt and efficient job, and were very professional job. They cleaned up any water drips inside and out. Windows look very good. I have used this "turner" system before and it really keeps the window cleaner longer. I won't go back to just the old soap and water cleaners. I highly recommend them.
