"Basic Bassments did a wonderful job in waterproofing and remodeling our basement. Everyone I dealt with was courteous and very professional. The workmanship was really good…township inspectors commented on good the electrical and plumbing work looked. Basic Basements was always on time and cleaned up after themselves. I highly recommend Basic Basements and would definitely use them again."

"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"Eddie and his crew did a great job on our full master bath remodel. We had it completely gutted and everything redone. I recommend them not only for the quality of work, but for the small things which set them apart from other contractors. The whole crew and all his subs worked extremely clean, they covered everything and cleaned up each day. All the workers were extremely nice and very respectful to us and our home and considerate to the fact we had a toddler running around. They have excellent attention to detail and did not cut any corners. Eddie gave us a lot of ideas through the whole process. We even had a snag at the very end with the tub fauceti bought not fitting, I was even willing to buy a new one to avoid any delays but Eddie and his plumber saw it through to the very end. The only critique I have is the communication was a little last minute sometimes. We wouldn't always know if they were working the next day until late the night before. Regardless I will be calling them for my next project and recommend you do also."

"We had French drains installed along the perimeter of our basement. The contractor had a large enough crew to complete the project in a day. They cleaned up all of the debris and left the basement in great shape. We have had one very large rain storm since the work and the basement had no sign of any water entering the basement, a job well done."

Basement Remodel FAQs, answered by experts

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

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.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
