How to evaluate Greatlakes Geothermal

Before hiring Greatlakes Geothermal for general contractor work in West Chicago, take a few minutes to verify their qualifications and confirm they are the right fit for your project. The right general contractor for one homeowner may not be the right fit for another, so do the diligence up front.

Verify licensing and insurance

Confirm that Greatlakes Geothermal carries an active IL contractor license appropriate for the scope of work, plus general liability and workers’ compensation coverage. Ask for the license number and look it up on the state board website. A general contractor that hesitates to share these details is a red flag, regardless of how favorable their reviews look.

Get a written, itemized quote

Request a detailed written estimate that lists materials, labor, permit fees, timeline, and payment schedule. Itemized quotes make it possible to compare Greatlakes Geothermal side-by-side with other general contractor options in West Chicago, and they protect you from scope creep once the work begins.

Ask about project experience

Ask Greatlakes Geothermal how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a general contractor actually shows up.
