Basement finishing in Great Lakes, IL

Great Lakes permits & building codes for basement remodels
Great Lakes is a federal installation (within North Chicago's city limits), so no municipal permit office operates on the base: construction on the installation itself, including its privatized family housing, is governed by the Navy and its housing partner rather than a local permit office. Remodels on nearby owner-occupied homes fall under the City of North Chicago or the Village of Lake Bluff, and any unincorporated Lake County parcel is permitted through the county's Planning, Building & Development department in Libertyville, which handles plan review, permits, and inspections. GS Construction manages the entire permit process — confirming the right jurisdiction, preparing the application, and coordinating inspections through final sign-off.
How your Great Lakes project runs
ProcessThe same six stages on every job — free in-home estimate through warranty.
Free in-home estimate
Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.
Itemized scope & contract
Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.
Design & selections
Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.
Permits & scheduling
We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.
The build, owner-supervised
Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.
Walkthrough & warranty
We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.
Testimonials
Your Neighbours in Great Lakes Love Us
Real reviews from homeowners. Ask us for live phone references.
GS Construction & Remodeling is the best of the best. We've hired them to work on 5 different properties (4 were extensive remodels) and continue to be thrilled with their work and have referred them to friends and family. I constantly bring to them pictures/ideas from Houzz & Pinterest and ask how we can duplicate high end looks on a budget and they pull it off - magnificently - every time. Not only do they know their craft, but they have a great design sense as well and make suggestions that always enhance the project. Their communication (providing estimates for changes as we go along, keeping in touch regarding scheduling, etc.) is excellent. They're nice people and incredibly respectful too - top notch all around.
