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.

"Very organized. As a working parent in a household with small children, Matrix’s process was very smooth. Once permits were approved, building moved according to the quoted timeline. We appreciated the app that kept homeowners in the loop about who would be on site on a given day and what was being done. Project oversight was very good. Our project manager was very responsive to our questions/concerns and a helpful go-between with the sub-contractors and inspectors."

Basement Remodel questions, answered by experts

It may not come as a surprise that the kitchen is the most expensive room in the house to renovate. This is due to the expensive appliances like the range, hood, and fridge, but also because the bones of the room—like electrical and plumbing—are expensive to move or replace. While there are ways to renovate a kitchen on a budget, it will always carry a hefty price tag, even if you cut some corners.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.
