"Becoming a new dad changes how you look at your home — suddenly, every space has to make sense for family life. We decided to remodel our basement bathroom to make it more comfortable for guests and easier for us as we adjust to life with a newborn. Century City Baths made the whole process incredibly smooth. The new bathroom has become a lifesaver for late-night routines, diaper changes, and when family visits to help with the baby. It’s functional, comfortable, and looks great too. For a first-time dad juggling a lot, having one less thing to worry about is a huge relief. Century City Baths turned a dark basement corner into a space that actually works for our growing family — clean, durable, and thoughtfully built. Couldn’t ask for a better experience."

"Vaclav Valek is the owner, he was one of 5 contractors I hired to provide professional advice on how to fix framing in the attic. One of the contractors never called back, and several others provided much different solutions. He provided the most honest solution without charging an arm an leg. Since I was under severe budget constraints he worked with me and had me gather the materials saving time and money for the both of us. He performed the work in one afternoon and provided good communication throughout the process."

"Remodel went extremely well even with material delays (not ordered through Rowe construction.) They were able to pivot and work on different areas of this extensive remodel. This crew showed up every day and notified us if they were not going to come or if they were delayed.They also pointed out and/or were able to troubleshoot areas of design that wouldn’t look aesthetically pleasing. In addition, they cleaned up the interior each day and regularly picked up construction waste placed in the garage during this process."

"We had EZ Bath N Shower remove our tub unit and install a shower instead. We contacted a larger well-known company, but we went with EZ Bath. Their prices were comparable, but EZ Bath's material was better (thicker base, walls, and glass!) The gentlemen installing the unit were polite and professional. We are extremely happy with the results."

This business is permanently closed as of June 2023.

"First of all, we are happy with the finished product of our master bathroom and walk-in closet. We are NOT happy with the owner of this business and his handling of our project. Jeff took time to design our space over several meetings. He promised that he would be available to choose tile/granite/light fixtures/plumbing fixtures whenever we needed him. Timeline was discussed with a 6 week from contract start and a project time of 3 weeks. Permit submission was done by myself with plans drawn by Jeff. We failed the permit process with 14 items that were not addressed due to insufficient drawings. Additional time/effort was required by Jeff and us to meet the requirements to meet code, which pushed our project back several weeks. We also paid more for the project due to Jeff needing to insure his workers for our village (a cost he should have known upfront). With new drawings, we re-submitted and were approved for work to begin. I can't say enough about the FANTASTIC workers that Jeff has on his team. They were courteous and did excellent work and even suggested design modifications that made sense. One of our first tasks was to pick out a granite surface. Jeff gave us the name of a granite place and that he'd meet us there. He NEVER showed. We picked granite on our own that day. We ordered tile - on our own. We chose lighting, plumbing, fixtures, and paint colors - on our own. The next time and ONLY time we saw Jeff for the duration of the project was when he delivered the vanity and asked for money (same visit). The total project ended up taking over three months to complete. Due to various project modifications/additions, we had no idea what our final invoice would be. We waited and waited for some type of final figure. 8 months after the project was completed we finally received a remaining balance invoice for over $11,000. We were shocked to receive this invoice so far after the project was completed. Jeff explained that COVID and not having an office manager were reasons behind us not getting an invoice before then and that we fell between the cracks. While we don't argue the price, we did not appreciate the length of time it took him to get the job done, nor the amount of time before we received a final invoice. When we offered to pay $2,000 each month for the next six months we were sent a very threatening email offering us three options for payment in full NOW. Suddenly this money is due NOW when he has carried this receivable for 8 months already? We will NEVER recommend Artistic Kitchen Concepts (Jeff) to anyone in the future. His involvement in the project started out well, but dropped off to the point where we never saw him, had no further input from him, and didn't receive an invoice until 8 months after the project was completed."

FAQs for second story addition building service projects in Island Lake, 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.
