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

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

Finishing your basement adds value to your home, providing an average return on investment (ROI) of around 75%. That means the typical basement refinishing costs of $32,000 will add an average of $24,000 to the value of your property. The value added to your home will depend on the price you pay to have the work completed, the area you live in, the quality of the work and building materials, and more.

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.

Home improvements that increase value not only enhance quality of life but also offer a high return on investment (ROI). Replacing a garage door has one of the best ROIs at 93%. Other high-ROI projects include remodeling your kitchen, installing a stone veneer, and replacing windows. These updates make homes more appealing to buyers and improve functionality, which helps if you plan to sell your home in the future.
