"My wife and I hired Joseph and Sons to remodel our basement. Angelo was accommodating and transparent with us at all times, suggesting solutions for each of the ideas and challenges we had, from fixing the homeâ s foundation, to custom creating our bay window, to matching our staircase and floor finish. They took the time to explain all the options within our budget and talk through each with us to make sure we were happy with the direction of the project each step of the way. His team is respectful and skilled, and there was constant communication regarding timeline, as well as arrival and departure times for each day of work. Attention to detail and a desire to make us happy were constantly present and I always felt like I was the only project they were working on; I would hire them again and recommend to my family and friends."

"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."

"It was a pleasure working with Rob and his team. From the initial meeting to go over the scope of the work, Rob was incredibly thorough and made the entire process extremely seamless. Throughout the renovation Rob was in constant communication with next steps and his attention to detail was impeccable. I would hire Bonus Home Remodeling for any future renovations and highly recommended them."

Customers say: Quick response

"There are so many good things to say about this company, from the initial consultation to the completion of the project. We selected then, after receiving four other estimates. Their pricing and services is what helped us in making our decision. Victor and his wife, Veronica handled everything. We had a complete bathroom gut and remodel. Their suggestions and patience were extremely helpful. The team was prompt and the work was impeccable. They were always available to answer our questions. They exceeded the completion date and finished before the projected end date, despite unexpected construction issues They left my house so clean. Their service is top notch, and we will be using them for future projects"

Basement Remodel FAQs, answered by experts

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’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’s legal to do so.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

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.
