We are a locally owned and operated basement finishing specialist servicing the Chicagoland area. Our focus is providing clients with a clear, upfront vision of expectations through a design/build approach. Our free design service provides potential customers with a collaborative consultation geared towards budget, wants, needs and lifestyle.

"After spending a good amount with a different contractor to remodel our main floor, we had to settle with the fact that a basement remodel was likely not in our short term plans. However, after taking a meeting with Matrix, we were pleasantly surprised that a substantial remodel was not out of the question after all. We were honestly so focused on the fact that something could get done that we didn’t nit pick on the finishes and some of the details, but wow were we impressed by the quality and workmanship of the end product. The project managers (we had Ben) do everything that’s needed to keep on schedule, but rest assured this does not mean that any shortcuts of any kind are taken. The sub-contractors used are simply amazing, and seem motivated to do whatever is needed to keep Matrix and the customers happy. Overall, we couldn’t be more pleased with how everything turned out!"

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."

Welcome to Stress-Free and High-Quality Remodeling. A great remodeling experience doesn’t happen by accident—it starts with choosing the right company that offers excellence through expert project consultants, professional designers, dedicated project managers, master installers, on-time project completion, and a 3-year project warranty. Our smooth, simple, and innovative approach ensures that every step of your remodeling journey is enjoyable, fulfilling, and frustration-free. From design to management to installation—we do it right. No exceptions. If you're ready to successfully complete your kitchen, bathroom, basement, or home remodeling project, schedule your in-home consultation with one of our friendly team members at 847-809-3355.

"Overall very happy with our experience with 4Ever Remodeling. They took our completely unfinished 1920s basement and created an in-law suite with extra-large bath. They were great at handling the City of Chicago permit process, which was one of my biggest concerns. Work included: Rebuilding basement stairs (sturdiest stairs I've ever seen). Adding a full bath with jetted tub, two-person shower, tile, all new plumbing including ejector pump. New exterior windows to comply with egress codes (really impressed with the exterior brickwork - you can't tell at all that any changes were made. They matched the grout and design perfectly). Installation of a large wet bar with dishwasher, shelving, quartz counters and cabinetry. Cabinets are very high quality. HVAC for basement and they extended the AC throughout first floor as well. Lighting, flooring, drywall, insulation etc. Highlights: Particularly impressed with their carpenter who did gorgeous, perfectly aligned work. Their designer, Magda was very helpful in guiding us and helping make selections (we've never done a project anywhere near this scope before). Communication was very clear and responsive. Workspace was immaculate at the end of every day. As with any project of this size there were a few nits: Their electrical team was slow to address a few concerns the inspector had and they disabled an outlet on the first floor. Granted, they were given an absolute trash mess of wiring to start out with. Also, the bathroom painter did not cover the tub when painting the ceiling, and I had to spend some time scraping flecks of paint off with a credit card. Those minor issues aside, I feel confident the project was done right, everyone that sees it absolutely gushes about the result, and I'm jealous that my in-law kitchen and bath are nicer than my own on our first floor! I'd definitely use 4Ever again (and in fact are considering a second project right now)."

"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."

FAQs for second story addition building service projects in Winfield, IL

Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location. 

Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.

Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications. 

Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.

Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents. 

These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.

Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases. 

Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
