Bob's Electric has over 38 years of experience. I am licensed in Arizona and bring the same expertise as I have all along. I offer extremely fair pricing and unparalled service. Majority of the work, I do by myself. I am insistent upon being the one who does all of the final electrical connections on any and all work performed by Bob's Electric. This allows me the opportunity to keep all of the work done at the highest level of quality possible. I take careful assessment of all the bidding that is performed in order to give the best possible price without compromising the quality of the work being performed. If you're looking for a contractor that will give you the quality you expect, I ask that you consider Bob's Electric. Specializing in smaller jobs, the ones that others do not want to do. But also more than happy to take on big jobs as well.

Basement Remodel questions, answered by experts

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

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.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

A finished basement does not always count as square footage, though this varies by state regulations. You may live in an area that allows for below-grade spaces to be considered in a home's official square footage. In those cases, the basement must meet certain conditions, like having a functional egress and being a livable space with flooring, finished walls, and temperature control. Your local assessor can confirm your area's policies regarding basement square footage.
