"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."

FAQs for second story addition building service projects in Harvard, 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.
