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."

"What can I say about Dan and crew? If there were six stars, I would have given them all of those! Our powder room job was also flooring for the hallway and laundry room, plus a utility sink. It was a total gut job in the bathroom. Dan could not have been nicer, quoted us a more than fair price and the job was finished in record time. He was very responsive to any questions we had (ok mostly me). Also, his workers (2) were fantastic. I'm not sure if I should name them, so I won't. They were efficient and professional, asked questions when needed and cleaned up the site and their work space (our garage) every single day. They treated our home with care, as well as our old appliances and new fixtures. We could not have been happier with all of it."

"We recently remodeled the bathrooms in our vacation house, and Century City Baths did an incredible job.

FAQs for attic remodeling projects in Downers Grove, IL

A loft conversion turns your unused attic or loft into a functional living space, like a bedroom or home office. Adding walls, ceilings, lighting, and even plumbing seamlessly integrates the new room with the rest of your home. It's a practical way to expand your living area and boost your property's value.

A loft is a finished and integrated living space created by converting an attic, while an attic is an isolated, unfinished area under the roof. The loft conversion process installs proper walls, ceilings, and utilities, transforming the space into a usable room that adds value to the home. In contrast, an attic remains largely unmodified and is typically reserved for storage.

Planning permission is required for a loft conversion because the project alters the structure and must meet strict building codes. A building permit, costing between $500 and $3,000, and mechanical permits, costing between $10 and $500 each, are mandatory. This regulatory process ensures safety, adherence to design standards, and the home's overall integrity during conversion.

A loft conversion takes several weeks because the project involves multiple phases, from design to finishing. The process requires careful planning, obtaining permits, executing structural changes, installing utilities, and completing final decorative work to ensure the converted area meets building codes and the homeowner’s requirements.

Choosing an alternative project instead of a loft conversion can be advantageous when a less complex project's return on investment is higher. Homeowners may opt for improvements like upgrading doors, windows, or adding a deck because these projects demand lower overall costs and fewer structural changes. Such alternatives can enhance home value and functionality with a more streamlined process.
