Basement finishing in Wilmette, IL
Basement finishing in Wilmette transforms underutilized lower levels into vibrant, functional extensions of the home. For the pre-war Colonials and Tudors east of Ridge Road, this often means converting damp, unfinished spaces with lower ceiling heights into cozy family rooms or guest suites, working around existing stone foundations and often shallow footings. Moving westward, the mid-century ranches and split-levels present opportunities to create more expansive recreational areas or home offices, leveraging slightly taller basements and often more straightforward structural layouts. Regardless of the home's era, a typical basement finishing project in Wilmette fundamentally redefines how homeowners interact with their entire property, adding significant livable square footage where only storage or utility once existed. We often see projects that aim to elevate these forgotten spaces into sophisticated retreats, complete with updated mechanicals and thoughtful design.
What Wilmette homeowners ask for
Wilmette homeowners frequently request dedicated home offices or study areas within their finished basements, a reflection of the town’s professional population. Family entertainment zones, often including wet bars or built-in media centers, are also highly sought after, particularly in homes with active children. Additionally, the creation of an extra bedroom with an accompanying bathroom, often for guests or older children, is a common desire, maximizing the home's potential for growing families.
About Wilmette
Wilmette offers a diverse architectural tapestry that speaks to its long history as a desirable North Shore community, and GS Construction is intimately familiar with the nuances of remodeling homes across its distinct eras.
East Wilmette, particularly the charming CAGE neighborhood—named for Chestnut, Ashland, Greenwood, and Elmwood avenues—is a treasure trove of pre-war architecture. Here, you’ll find an abundance of colonials, Tudors, Victorians, and foursquares, many constructed between the 1890s and 1930s. Their proximity to landmarks like Gillson Park and the distinctive 1928 Spanish Court arcades of Plaza del Lago adds to their enduring appeal. As you move farther west in Wilmette, the housing stock transitions towards mid-century designs, particularly around areas like Edens Plaza. These homes, often built from the 1950s onward, present a different set of remodeling opportunities and challenges. The community's excellent public schools, with most of the village feeding into District 39 and then the highly regarded New Trier High School, also contribute to the desirability of remodeling and improving homes here. Commuting is well-served by both the Metra UP-N line from the Wilmette Metra station and the Purple Line's Linden terminal, making home improvements a sound investment for families valuing both quality of life and convenient access to Chicago.
For pre-war homes like the Colonials and Tudors in East Wilmette, basement finishing often involves addressing lower ceiling heights and replacing tired drain tile to mitigate dampness. Mid-century ranches around Edens Plaza may offer slightly more open basement layouts, but still benefit from updated mechanical systems and robust waterproofing due to flood-prone areas. The sturdy original construction of these homes means existing mechanicals, like galvanized supply lines, often require updating during a basement remodel. Ejector pumps are frequently necessary in flood-prone areas to manage water, while lot constraints can influence egress window placement. The Village's lead service line replacement policy also impacts basement projects, as an owner-triggered replacement adds to project considerations.
Wilmette requires specific inspections during basement finishing, including framing, electrical, plumbing, and insulation, to ensure compliance with local building codes and safety standards. GS Construction & Remodeling expertly manages all necessary permit applications and schedules these critical inspections with the Wilmette Community Development Department, ensuring a smooth and compliant project progression.

We cannot say enough good things about GS Construction and about Greg and Patryk. We hired them on a strong recommendation from a friend and are very pleased with the results. Our project included remodeling a kitchen and master bathroom and adding wood floors to several rooms in our condo. We had definite ideas of what we wanted since we have done many remodeling projects in several previous homes, but both Patryk and Greg added great value with suggestions and ideas of their own based on their experience and talent. Their follow through was excellent and we feel confident that if anything needs attention, they will be there to make it right. P.S. They did a great clean up at the end of the project......i
