"Steve Gavin, the owner came out and provided me with a great price that was inclusive of the entire scope of the project. During our meeting he took the time to explain the process that his company uses. Once the permits were issued the crew arrived the next morning at 7:00 a.m. as promised. The crew met the deadline for a 1:30 inspection from the Village of Deerfield. They not only met the deadline but they passed the inspection without any issues to be corrected. The crew worked until 7:00 p.m. completing the job. I would also note that they left my home spotless!"

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