"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."

"I was looking to completely remodel two of my bathrooms (demolition job). I hired Belmax (Maksim) based on reviews and the estimate for the projects (i.e. $15K). I could not have been any happier with the work that Max and his guys performed. Max is very professional, detail oriented, and the quality of his work is EXCELLENT. Living in my house for over 15 years I have never been more satisfied with a contractor. He is very transparent and trustworthy, keeping me informed of any decisions/deviations from the original plan. The project took slightly longer than expected but not due to any fault of the company. There were some "unexpected issues" with the main bathroom that caused the project to take slightly longer. Max and his team was here every day working. There was very good communication and he kept me updated throughout the entire project. I was so impressed and happy with m bathrooms that I hired him for additional work in my dining room and will be reaching out to him next year when I am ready to remodel my basement. EXCELLENT JOB BELMAX!!"

"My husband and I are beyond grateful to All-Star contractors for doing an excellent job on finishing/remodelling our basement. We never imagined that our basement will look this good despite the small size (we live in a townhome). Every space was made functional. Bill (the contractor) is very fair, always listen and give recommendations as needed. The price is appropriate for the excellent work done. Bill's crew is very hardworking and takes pride in his work - making sure that we will be pleased and always asked if there is anything or issue that needs to be addressed. We are in the process of lining up our next project with Bill. We will definitely not settle for another company for any work we need whether it is something minor or major. If you are looking for someone trustworthy - we will definitely recommend Bill without a doubt."

"My experience working with Basement Gurus, especially Phil Thistle, was fantastic. Phil and the crew were very thoughtful and responsive from the moment I called basement gurus until the moment my installation in my basement was complete. I greatly appreciated how dedicated Phil was in answering my questions and checking in with me regularly about my concerns and how the job was going throughout the entire process. Would definitely recommend basement gurus for your waterproofing needs!"

I bought a $49 big deal for this service and it went perfect. We spent over $10,000 because we did not have any sump pumps for the basement and now we have five. It was a big project for the basement that needed to be done. It went wonderful

"My husband and I are new homeowners in Yardley; we interviewed 10+ contractors in the area to complete a basement remodel at our home. Renovations can be scary and we were very adamant about choosing the right partner for the project. We are so glad that we chose Improverite! Robert and his team are truly the best in the industry! Robert is a high-energy, passionate professional who made sure we had a first-class experience. Every part of this process exceeded our expectations. He was diligent about earning our business and building our trust. I really can't put into words how good his team is! Everyday I was blown away at the progress and craftsmanship of their work. I was not expecting that level of talent and customization to go into the project. We have a space that is above and beyond anything we were expecting and could not be happier and pricing was very competitive! The gentlemen at Improverite are thoughtful, professional, and incredibly skilled at their work. We highly recommend them and will absolutely use them for our next home project!"

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.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Kitchens and bathrooms are typically the most expensive rooms to renovate. The high cost is due to several factors, including expensive appliances like ranges, hoods, and refrigerators, as well as costly fixtures. The 'bones' of the room, such as electrical and plumbing, are also expensive to move or replace. Because of the vast amount of prep work, finishing, and specialized labor involved in a relatively small footprint, these projects can cost double or more than a living space remodel. Even when trying to renovate on a budget, kitchens and bathrooms will likely carry a hefty price tag.

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.
