*ISLAND HOMECRAFT- Award winning, true kitchen and bath professionals! *"Dan and his crew were amazing" *"On time with every phase of my project. Never missed an appointment" *"I must be dreaming... They handled everything so professionally, no excuses, highest quality workmanship"- FREE KITCHEN DESIGN AND OF COURSE FREE ESTIMATES...

"As an Electrician for 30 years, I am not used to having contractors perform work on my home. However, I was doing a major renovation including the complete remodel of my kitchen, dining room, living room, and new stairs/hallway that was more than I would be handle. Dan was the first contractor I met with and I knew right away he was the guy. At our first meeting, he brought his Kitchen designer from Gallo-Rossi (Dominick) and went over everything in detail. Come project time, Dan and his crew were punctual and showed up as scheduled. Dan’s Crew are true craftsmen and all of his subs/trades are licensed professionals. Their quality workmanship was evident in both the things you can see, as well as the things you can’t. I have already recommended Dan to family and friends and they are just as happy as I am."

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.
