"My journey began when I met Mario from Be Home Remodeling. I started with just one bathroom remodel, and I was immediately impressed by the professionalism, attention to detail, and high-quality craftsmanship he and his team delivered. The communication throughout the project was clear and consistent, and they made sure every step met my expectations. Since then, I?ve trusted Be Home Remodeling with additional projects and have always been more than satisfied with the results.

"A friend had his kitchen done and referred Joe saying he was great. I checked out others whose homes he did. They also raved about Joe and his work. I had a major water leak 2 bedroom 2 bath and needed EVERYTHING redone. I agreed with all those for these reason: He’s honest, and reliable, he assisted me and guided me on ever step in making choices of new products from expanding my kitchen down to small details like floor molding. He is respectful and kind and he charged fair prices. You’d be lucky to get him. And glad you did. I still have people come in 15 years later and love the work he’s home. 3 neighbors hired him after seeing my place. One this year and I saw it and he still does amazing work. Don’t waste a minute , get him while you can! Wendy Dan"

Basement Remodel FAQs, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging. Kitchen design, layout, electrical, and plumbing needs all depend on each other for the success of the entire project, and mistakes early in the project can cause trouble later on.

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.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.
