Biango Construction strives on giving all of our customers the best quality craftsmanship and pricing in the industry. Locally owned operated. We guarantee your satisfaction! Free estimates.
"I had Biango Construction complete a full gut renovation of my main floor powder room and laundry room/mudroom. This included a major change in layouts and moving walls, doors, HVAC, plumbing, gas lines, and electrical. I also had custom cabinets and hall tree built for the space. The final result is exceptional (see photos). While the time ended up taking longer than originally expected, it was worth it to have a trusted pro do the work and to deal with the permit process. The company was easy to work with, professional, and maintained a clean workspace across my house. All individuals working on my house with Nick Biango paid high attention to detail throughout the entire process. I would highly recommend Biango Construction to anyone doing renovations or wanting built-ins added to their home."

"Miro redid our kitchen and half bath and we're thrilled with the results. We got a few quotes and ultimately went with Homewise Remodelers because the price was reasonable and Miro was so thorough in walking us through our options. He helped us select cabinets and worked through several versions of the kitchen layout until we were happy with it--we were easily able to swap out cabinet layouts and finishings, like adding a farmhouse sink. His crew were reliable, on-time, and respectful of our property throughout the remodel and we appreciated their attention to detail. They solicited our input on decorative details and were quick to fix things we didn't like, e.g., the location of kitchen cabinet pulls. We felt they treated our home as they would their own. The project even wrapped up a few days early. We would absolutely recommend Homewise Remodelers and choose them for future projects."

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.
