"We needed an additional office space within our home. The concerns were removing an existing fireplace and hearth and replacing the hardwood floor to match what was already there, removing the chimney and patching the roof, moving a heating vent and again, patching the hardwood floors to match, adding an interior door, and moving lighting and electrical outlets. David was onsite everyday to either do the work himself or oversee the work by his subcontractors. They do quality work. The floors look great, the new wall is perfect, the roof was done well, the new interior door was installed well and looks like it was always meant to be there. Also, the work site was always cleaned up at the end of each work day. David is also very flexible, easy to communicate with, seems to truly care about your project, and works with contractors who do quality work."

"Jose was friendly and professional. My job was not considered large by any means (re-hanging a gate) but he completed it in short order and cleaned up after himself. I really appreciated the fact he wanted to insure I was satisfied with the work because he needed to cut an inch off of the gate.....which I was. I would certainly call him again."

Basement Remodel FAQs, answered by experts

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
