Three things: Our people, the quality of our work, and our customer service. We have highly trained technicians who are all certified to work on all types of chimneys. We instill a drive to do things right the first time, and we refuse to accept low quality work or materials that won't hold up over time. Your safety is our priority, and any shoddy work or faulty parts put you and your home at risk, so we just don't accept anything but the best. We will explain everything about your chimney to you so you understand exactly what we're doing and why so there's no guesswork. That's why people say we're the best chimney cleaners in the Wilmington area!
