Alfonso & Zeke were on time and very professional. They checked why I was getting sewage backup on the floor drain (for A/C condensation) in the basement of my new house. They checked out everything in my house and did not find any issues. I had them check for blockages or issues with the pipes with a camera (for an extra fee); not really anything found. Said it may be an issue when there is heavy rains and the city sewer line backs up. They answered any questions I had and were very pleasant. They did advise today’s service call has a 30 day guarantee; if there is another problem in the next 30 days they will come back at no charge.
