Home additions in Schaumburg, IL

GS Construction provides remodeling services to homeowners in Schaumburg and throughout the northwest suburbs. We bring decades of experience to kitchen, bathroom, and whole-home renovation projects across Cook County. Let us help you transform your Schaumburg home.

Schaumburg's housing story begins in 1959, when builder Alfred Campanelli broke ground on Weathersfield near Schaumburg and Springinsguth Roads. That development grew through more than twenty phases into roughly a fifth of the village's housing, starting with the "W" section, where ranch models carried New England names on streets like Warwick and Winthrop. Those mid-century ranches and split-levels, plus later subdivisions such as Sheffield Park and townhome communities like Nantucket Cove, are the homes we remodel most: compact kitchens opened to the family room, hall baths rebuilt, basements finished, and additions that give a one-story Campanelli house real breathing room. Utility work is refreshingly simple here — Schaumburg has been on Lake Michigan water since 1988, and the village's 2025 inventory found zero lead service lines. With District 54 schools and the Milwaukee District West Metra station beside Wintrust Field, GS Construction remodels kitchens, baths, basements, and whole homes throughout Schaumburg.

We also take on plenty of projects in Timbercrest, where Mor-Well Builders mixed ranches, raised ranches, split-levels, and two-story plans from the mid-1960s onward, in the 1960s single-family blocks of Lexington Fields Estates, and among the late-1970s and '80s coach homes of Lexington Village. One pocket plays by different rules: the Olde Schaumburg Centre overlay district around the Schaumburg and Roselle Road intersection, established in 1978 to preserve what began in the 1840s as the farming settlement of Sarah's Grove. Exterior projects there go through the village's OSC design review before final approval from the Village Board, so we build that step into the schedule from day one. Village-wide, Schaumburg requires every contractor to hold a village-issued business license before a permit can be released — out-of-town firms carry a dedicated license, while plumbers and roofers show state credentials instead — and basement, bathroom, and kitchen alterations each get a formal plan review with detailed drawings and a written scope of work, paperwork we prepare as a matter of course.

Schaumburg permits & building codes for home additions

Schaumburg runs residential permits through its OpenGov online portal, and kitchen, bath, basement, and addition projects all go through plan review — the village's stated goal is ten business days with no expedited option, so spring and summer projects should build that into the schedule. Contractors must hold a Schaumburg contractor's business license before a permit is issued, and remodel permit fees run 1% of construction value. GS Construction manages the entire permit process — portal submittal, plan-review responses, licensing, and inspections — on every Schaumburg project.

How your Schaumburg 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 Schaumburg Love Us

Real reviews from homeowners. Ask us for live phone references.

We had a truly amazing experience with GS Construction remodeling our kitchen and first floor. As remodeling novices, we connected with GS Construction through our designer and were so happy with this match made in heaven. Having heard horror stories from friends about remodels that went on forever and tales of unreliable contractors who don’t communicate, we were nervous when we started and expected the process to be long and painful. Our experience could not have been more different. Greg and Patryk were great at keeping us informed and the total amount of time from demo to the unveiling to friends and family was really reasonable at a little over 2 months. We received great personalized attention and they were great at offering ideas and trouble shooting various things that came up. But the real highlight is the quality of the work. They were so attentive and made sure that we loved every inch of our new space. We have never loved our house more!
