## The honest read

Bill Marek Excavating & Septic Systems is a septic business that says it has been in business 36 years. Its own site lists a service area that includes Bethany, Woodbridge, Orange, Hamden, North Haven and Wallingford.

A 2024 customer said Bill's pricing was very reasonable, with no surprises, and called him knowledgeable. A 2022 customer praised an inspection job. A 2021 customer recommended Bill for septic service or a whole new system.

A 2024 customer hired Bill for a septic inspection before buying a house and said he found the system needed replacing, gave a quote for the whole job, then put the work off repeatedly and never came back to complete it. That 2024 customer also said the yard was left a mess after it was dug up for the inspections and testing, and that hiring another contractor put the job over budget by thousands.

The company holds an A+ grade with the Better Business Bureau and a 4.2-star Google rating from 10 ratings.

**Strengths:**
- Clear septic pricing — a 2024 customer said there were no surprises
- Septic system work — a 2021 customer recommended Bill for a new system

**Concerns:**
- A stalled job — a 2024 customer said it was put off, never completed
- A dug-up yard — a 2024 customer said it was left a mess
