"NE Renovations is a general contractor whose network of contractors provided services to me as I was getting ready to sell the house.  The electrical service went very well with Mr. Martucci doing great work and advising me about things that did not need to be done.  I feel that he was a great advisor!
The flooring in the basement also went very well with the NE folks advising me about the best way to approach the installation.  Everything was perfect when they left.  I truly appreciated their workmanship.

"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

Basement Remodel FAQs, answered by experts

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

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.

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.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.
