Basement finishing in Great Lakes, IL

GS Construction provides comprehensive remodeling services to homeowners in Great Lakes and throughout Lake County. We're a family-owned and operated design-build firm with deep roots in the Chicago suburbs, specializing in kitchen, bathroom, and whole-home renovations. Let us bring your remodeling vision to life.

Great Lakes is not a typical suburb: the entire community is Naval Station Great Lakes — a federal installation with its own ZIP code (60088) inside North Chicago's city limits — home of the Navy's only boot camp at Recruit Training Command and the largest military installation in Illinois, sitting in Shields Township between North Chicago and Lake Bluff. Housing on base is privatized — Great Lakes Family Housing, managed by Hunt Military Communities, maintains more than 1,460 duplexes, triplexes, and single-family homes across six neighborhoods, including Forrestal Village beside the newly rebuilt Forrestal Elementary School (North Chicago District 187). Even the water is Navy-run, drawn from Lake Michigan and treated at the base's own plant rather than by a village utility. So when Great Lakes families plan a remodel, it is usually for an owner-occupied house just outside the gates, and that is where GS Construction comes in: kitchen and bathroom renovations, basement finishing, additions, and whole-home updates for Navy households and base civilian staff putting down roots near the Great Lakes Metra stop on the UP-N line.

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

Process

The same six stages on every job — free in-home estimate through warranty.

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.
