Define the job
Write down what you need and where the lines connect. Include photos, a site plan and any utility letters you have. A clear description makes the estimate more accurate and shows how well the contractor listens.
Ask about experience
Ask what similar jobs they have done and how often. A contractor who installs sewer laterals every week will do it better than one who tried it once. For boring, rock or deep work, ask about that experience in particular.
Ask about requirements and coverage
Rules vary by city, county and utility for who may do the work and what permits apply. Ask what applies to your job and what insurance coverage the contractor carries, and keep a record of the answer.
Ask about locating and safety
A good contractor calls 811, potholes at crossings and has a plan for trench safety. Ask how they handle each, and how they protect your lawn, driveway and neighbors.
Get it in writing
A written estimate lists scope, materials, depth, restoration, schedule and payment terms. It also states what happens if rock, water or an unmarked line is found.
Check references and reviews
Read recent reviews and ask for references from similar jobs. Ask how the crew handled surprises, not only how the finished work looked.
Hire the contractor who asks the most questions about your site before quoting it.
