"Joseph and Sons had done our waterproofing in our finish basement. What I liked about this company was, they were the only company to do waterproofing and finish our basement with Sheetrock, trim, trim and floors. A one stop company that does all. Always delt with Angelo and he was very knowledgeable. Will be using them for future jobs."

"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."

"During the initial quote process Tom was very knowledgeable and put together a great plan for basement remodeling. My basement was transformed from the style of 50's to a modern basement that I can enjoy with my family. The staff was friendly and worked diligently 6 days a week without interrupting to my day. I received updates through the project from Tom on the progress. The company provided completive rates and this was the best money spent. I would highly recommend this company to anyone looking for quality work, your will not be disappointed."

"Cesar and his crew just finished a remodel of my master bathroom. This is the second major project completed in my home by CSZ (prior kitchen remodel) and once again they exceeded my expectations. Cesar worked with me along the way to come up with the perfect design to ensure all my requirements were met. He is knowledgeable and his attention to detail is second to none. The CSZ crew, Armondo and Benjamin were also a pleasure to work with. They are knowledgeable, trustworthy, and hardworking. They also did an exceptional job cleaning up at the end of each work day. My dog even loves them! I highly recommend CSZ Construction. They will most certainly be back for future projects in my home!"

"Carmello is great. After a flood ruined my basement these guys completely repaired and renovated the space including new french drains, vinyl sheeting behind the drywall, dry locked the window wells and caulked all necessary gaps. Not cheap but they knew exactly what they were doing and since our area has had several storms w record rainfall and my basement has been bone dry. Would use them again in a heartbeat. Highly recommend."

Basement Remodel questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

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.
