"Ryan & his team were wonderful & our bathroom came out beautifully! Ryan was extremely informative and helpful, answering our countless questions both before and during the remodel job. He worked diligently for three weeks to bring new life to the space. The quotes were also incredibly affordable given the high quality of the work. We would 100% recommend Indigo & we look forward to working with them again very soon."

"We had a great experience with the Lux Renovations and Owens Corning team. The whole process was very easy from designing the space, selecting colors, and having a contract manager who organized the entire basement remodel including all the trades and inspections. We were sold on the Owens Corning materials for the basement and that they were engineered specifically for a basement space. Would highly recommend this team for your basement remodel needs."

"I worked with Prestige on a few, somewhat unique, projects recently, including renovating an old detached garage and fixing up my basement after a French drain/sump pump install. It was definitely a 5 star experience. Matt seemed more like a partner than a contractorâ ¦he brought creative solutions and ideas to the project, was transparent with updates and showing off milestones as they were completed, and even went the extra mile to ensure quality (example: he insisted that siding be sent back because it did not quite match the rest of the house). He also hooked me up with a custom side door for my EV charger cord that is going to make charging outside so much easier. I will definitely be hitting him / Prestige up again in the future."

"We just had our basement finished. Not re-finished but finished for the first time. The house was built in 1924 with a dirt floor in the basement and low hanging pipes, overall a very challenging job. We wanted to turn it to a family room with a full bath, laundry room, closets, etc. Joe's guys (Chico and Javier) did a fantastic job. They are knowledgeable, thorough, thoughtful, and creative. We would recommend them to anyone without hesitation."

"Cesar remodeled our basement, and we cannot be happier with his work! He worked with us the whole way to make sure we were happy with the work. He even put a custom wine rack in. The new basement is so beautiful and we get so many compliments. He has done work for us before and he does excellent work, is always available and easy to reach, and has a professional and kind team of workers. Thank you Cesar!!"

"Alex and his team did an excellent job remodeling our basement. He was very easy to work with and provided many suggestions. True professional and cares about the work his team is doing. Great customer service. I would recommend him without issue. Most contractors that i dealt with did not want to be bothered when I mention I wanted permits. Alex didn't mind working with permits. When my basement was approved by 3 township inspectors they all said what a great job he did! Thanks Alex and Team"

Basement Remodel questions, answered by experts

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

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.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

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.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.
