If you're ready to successfully complete your kitchen, bathroom, basement, or home remodeling project, schedule your in-home consultation with one of our friendly team members at 847-809-3355.

"The quality of work is fantastic, and Marek is the best project manager you could ask for. The reason I removed one star is because I believe the quoted contract price, specifically for allowances, can improve. You should expect to add a minimum of $20,000 to your contract price. I also recommend referring to your contract throughout to ensure you aren’t getting an extra charge for something that should be included. Like I said, the quality of work is fantastic, but the up front pricing can improve."

"As someone who travels often for work, I don’t have time to micromanage home projects — I need things done right, on time, and with minimal hassle. Century City Baths completely delivered. The team handled the remodel with impressive precision. Every fixture, tile, and finish was installed perfectly, and the space was spotless when I got back.

FAQs for second story addition building service projects in Hillside, IL

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
