Questions
Do you cover all of Johns Island?
Yes, including ZIP 29455. The company that calls you back will confirm your address is in their service area.
How fast can someone come out?
It depends on the day and how many calls follow a storm. Say in your request if water is still coming in, or if anyone at home has asthma or a weak immune system. The company will tell you when they can come.
Do I get a price first?
Ask for a written scope and price before work starts. With active water, drying often starts on the first visit; ask what the first day will cost and how drying is billed before you sign.
