Is it worth it to add a second story?

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.

Is it better to build up or out?

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.

How can my home’s foundation be reinforced to support a second story?

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.

"My partner and I have had the pleasure of working with Dan, David and the hardworking crew at LB Construction & Remodeling for our what is now an extensive home restoration and renovation project. I cannot express how thrilled I am with the results thus far. From start to finish, their team demonstrated an unparalleled level of knowledge, speed, and attentiveness that truly exceeded my expectations. Truthfully, I didn’t know where to begin with my project, so I was very happy when Angi.com recommended LB. Dan responded quickly and was able to meet me at the house and walk the entire site with me. I had recently purchased my house and it needed extensive repair from years of water damage, including repair and replacement of the wood framing, installation of proper drainage, and foundation work. What truly set Dan and team at LB Construction & Remodeling apart was their willingness to help me hash out the details and various plans for our projects. Dan and David patiently worked with me to explore different options, providing valuable insights and recommendations based on their extensive experience, such as navigating permitting, advising on order of operation. This collaborative approach made me the decision-making process easier and less stressful as I had never done anything like this before. The speed at which LB Construction & Remodeling worked on my projects was truly impressive. They efficiently managed their time without compromising on the quality of their work. Every step of the way, it was evident that they were dedicated to completing the project promptly, ensuring minimal disruption to my daily life. Not to mention their attention to detail and commitment to quality craftsmanship were evident in every aspect of the projects, particularly with the reframing and painting. One of the standout qualities of LB Construction & Remodeling is their exceptional attentiveness. Dan consistently paid close attention to my needs and concerns, making me feel valued as a client. An example of this was when I communicated how I wanted the trim around the windows to look, both inside and out. I sent Dan pictures to illustrate what I was expecting, and he listened to me, verified specifics of my ideas, and walked me through how they would be able to achieve the look easily. Their work was seamless and they captured my vision perfectly. Right from the get-go we felt a sense of trust with Dan and team and that really helped make this entire process enjoyable. I wholeheartedly recommend LB Construction and Remodeling to anyone seeking a trustworthy and skilled team for their home improvement needs. I am eager to continue our other home projects with LB Construction & Remodeling in 2024."
