Basement finishing in Great Lakes, IL

Basement finishing in Great Lakes often involves transforming the lower levels of mid-century and split-level homes found just outside the base gates. Many of these residences, built from the 1950s through the 1970s, feature unfinished basements with open layouts, offering a blank canvas for expansion. Converting these spaces significantly increases usable square footage, providing much-needed room for growing families or accommodating evolving needs. The typical project here transforms a utilitarian space into a vibrant, functional extension of the home, often involving new walls, flooring, lighting, and climate control to create comfortable living areas. We frequently see these renovations add substantial value and utility to homes near the Naval Station.

What Great Lakes homeowners ask for

Great Lakes homeowners frequently request dedicated home offices or study areas within their finished basements, especially given the professional demands of military and civilian staff. Family entertainment zones, complete with media rooms or play areas for children, are also highly sought after. Another common request is for additional bedrooms, often with an attached bathroom, to host extended family or provide more private living quarters.

About Great Lakes

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. So when Great Lakes families plan a remodel, it is usually for an owner-occupied house just outside the gates.

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.

I don't even know where to begin, Patryk & Greg are just amazing! We hired them to remodel approximately 4000 sqft of a 1985 house which included an unfinished basement. The whole experience could not have been better. It took about 7 months and for most of it, we lived in the house with two children. They are incredibly professional, can troubleshoot any issue and are 100% dependable. Patryk led the project and he was very detail-oriented. Everything had a purpose and was finished with beautiful extra touches. I changed my mind frequently and they didn't miss a beat. They worked around the changes and kept moving. The materials they used and the teams they brought in were all top notch. They didn't spend money where it wasn't necessary and in fact, they were always trying to find ways to save money. Finally, they are really nice guys. Polite, respectful and very accomodating. After spending so long in my house, we (almost) miss having the around. As I mentioned, we had the whole house remodeled and its impossible to post every picture so I will showcase just a few highlights. The whole house is beautiful! Scott & I THANK YOU!!!
