I'm a sole proprietor. On very rare occasion, I may need to sub-contract a portion of your repairs. I'm centrally located along the shores of Lake Shelbyville, my shop is just SE of Findlay. Generally, we will discuss payment. It largely depends on the scope of the project. You and I will sit down and discuss completion goals, and if a large project, payment may be required in measurable and pre approved stages.

Basement Remodel questions, answered by experts

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

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.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.
