Over 30 years of experience and meticulous attention detail mean you can be confident in your remodeling project.

"What can I say about Dan and crew? If there were six stars, I would have given them all of those! Our powder room job was also flooring for the hallway and laundry room, plus a utility sink. It was a total gut job in the bathroom. Dan could not have been nicer, quoted us a more than fair price and the job was finished in record time. He was very responsive to any questions we had (ok mostly me). Also, his workers (2) were fantastic. I'm not sure if I should name them, so I won't. They were efficient and professional, asked questions when needed and cleaned up the site and their work space (our garage) every single day. They treated our home with care, as well as our old appliances and new fixtures. We could not have been happier with all of it."

Chicagoland's Reliable Home Improvement Company servicing the City of Chicago and most suburbs. We specialize in full remodels of kitchens, bathrooms, condos and basements. We do not offer repair work or partial remodels. Celebrating 25 years in business.

"Miro redid our kitchen and half bath and we're thrilled with the results. We got a few quotes and ultimately went with Homewise Remodelers because the price was reasonable and Miro was so thorough in walking us through our options. He helped us select cabinets and worked through several versions of the kitchen layout until we were happy with it--we were easily able to swap out cabinet layouts and finishings, like adding a farmhouse sink. His crew were reliable, on-time, and respectful of our property throughout the remodel and we appreciated their attention to detail. They solicited our input on decorative details and were quick to fix things we didn't like, e.g., the location of kitchen cabinet pulls. We felt they treated our home as they would their own. The project even wrapped up a few days early. We would absolutely recommend Homewise Remodelers and choose them for future projects."

Second story addition building services FAQs

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.
