This was our first experience with Alpine High Window Cleaning and our company(Mountain Home Lodge, Leavenworth) was very happy with the outcome. Alpine first came out to do an estimate, we agreed on the cost and they promptly returned based on our schedule. The owner and staff were courteous and very respectful of the property. The cleaning was thorough and efficient. We plan to contract with them again later this year, since we typically have the windows cleaned twice annually.
