Q: Is a walkout basement below grade?

• <div><p>A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can&rsquo;t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it&rsquo;s legal to do so.</p></div>

Q: How hard is it to add a basement to an existing house?

"I very highly recommend Jamie Adams. He showed up on time, finished on schedule, and did an amazing job, absolutely top-notch work. He has attention to detail, finds great solutions to weird quirks that come with a property's existing layout. I trust his judgement, and take his recommendations/solutions. Which is saying a lot I am normally quite suspicious of contractors, but Jamie has won my trust and loyalty. If any of my buildings need work, Jamie will get it. The quality is great and the cost is reasonable, with no sticker shock."

"Everything went wonderfully with this company. They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work. Once they started, the team (three people came) worked together like a well-oiled machine. One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring. Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues. They cleaned up after themselves very neatly. They also replaced the light switch with a dimmer switch at no extra cost! Well within my budget, and came in even lower than their original (FREE) estimate! I would highly recommend this company to anyone in the Bergen County area.

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
