Home additions in Northlake, IL

Northlake's housing story is unusually specific: beginning in the late 1930s, the Midland Development Company sold "semi-finished" Cape Cod and ranch houses near North Avenue and Wolf Road that buyers finished themselves, and after incorporating in 1949 the city filled out through the 1950s and '60s, when the Automatic Electric telephone plant arrived and industry settled the west side while homes stayed east. The result is a town of compact postwar Cape Cods and ranches on modest lots — a natural fit for what GS Construction does: opening up small kitchens, updating tight bathrooms, finishing basements into real living space, and taking on whole-home remodels or additions when the footprint runs out. Worth knowing: Northlake runs its own Lake Michigan water system and is replacing the city's remaining lead service lines at no cost to homeowners — check your line before plumbing-heavy work. Families feed Mannheim District 83 schools and West Leyden High School, with the I-294/North Avenue interchange minutes away.

Northlake permits & building codes for home additions

Remodeling permits in Northlake go through the City of Northlake Building Department (708-343-8700), and every contractor and subcontractor listed on a permit must carry a current city contractor registration — an annual $100 license backed by a $10,000 bond and a certificate of insurance naming the City. On pre-1978 homes, which covers most of Northlake's postwar housing stock, the city requires proof of EPA Renovation, Repair and Painting (RRP) certification before it issues a remodeling permit. GS Construction manages the entire permit process for Northlake projects — registration paperwork, application submission, and inspection coordination included.

5 Stars

I cannot say enough good things about Greg & Patryk and their team! One of my biggest hesitations about doing such a large project was knowing how hard it is to find a reliable contractor who would give us top quality work at a reasonable price. GS Construction exceeded our expectations in all areas! Our first floor remodel (kitchen renovation with wall removal, half bath remodel, new hardwood floors, updated laundry room) was completed right on schedule. Their attention to detail is amazing, often fixing or adjusting things that I didn't even notice. Their team was a pleasure to have in the house, all were so respectful and patient with our family as we mostly worked from home through the construction. The quality of work from their entire team (carpenters, plumbers, hvac, and painters) was well worth the price. We are beyond thrilled with our updated house! I would recommend GS in a heartbeat and will definitely call on them when it is time to update the rest of the house.
