"This project was supposed to be "phase one" of three projects that we hired NE Renovation to complete.  On day one, the basement was prepped - all carpeting was covered and baseboard heating covers were removed.  Sheetrock was supposed to be installed on the next day, but due to a serious injury to the sub-contractor, that was not done.  Instead, demolition work began on what was supposed to be "phase two" of the project - the remodeling of a bathroom.  We had not been expecting this change in schedule and to be fair, neither did anyone else.  The basement project was put on hold until an alternate plan could be made.  A few weeks later, work began again on the basement.  The sheetrock was installed very well and in quick time.  The plaster work was completed perfectly which was no small task given the length of the walls. Additionally, the paint job was done perfectly.  The new six-panel doors, wall mounted television, upgraded lighting, and new baseboard heating covers helped complete the transition of the space from 1970 to 2012!

The value we received from this project has exceeded our expectations.  We added a pool table and two sectional sofas to complete our new recreational space.  It serves as a great "man cave" as well as a great place for family and friends to hang out.  NE Renovations did a great job renovating our basement."

"It is a waste of money. The great majority of people are not going to find any value out of the service. If you need design consultation, you need a full service consultation. If you already have knowledge and experience, and you just need to get a few ideas, then you don't need to pay for that. You can just get a magazine or a book since you already have the knowledge of basic designs in your head or a little bit of experience. To have someone call you and give you information over the phone, you are not getting the personal service that you need. You may as well take the money $49 and apply it to something else like getting someone else to come out and give you the service that you need. Because, you are not getting much, you are not getting anything at all. They are going to have you do the work. After talking to them and I was talking to other home designers, I found out that that was a waste of time and waste of money. I gave them a C because they didn't fail at what they do but they don't offer any value for what they do. There's not much value to it. The cost was fair. They didn't do a terrible job and the cost isn't terrible, it was only $49. It just has a very low value. For responsiveness I gave them a B because they will answer your phone and answer your emails."

Basement Remodel FAQs, answered by experts

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.
