I've used Capitol Cleaning for years and the people there are efficient and professional.They did roof and skylight cleaning and everything turned out great because they did--and usually do--a great job. I don't have any complaints about anything. It's easy to book appointments and they call back right away, and I usually talk with Peter--which is nice. It's very personalized service they offer and feels like a small business, which is really refreshing. I prefer businesses like that and I encourage doing business with small businesses.
