"Volcano Builders transformed our dark, underutilized basement into a cozy, functional hangout space with a wet bar. From framing to lighting and flooring, everything was handled professionally. Bar checked in weekly, communicated promptly, and made thoughtful suggestions for built-ins and finishes. The result is a warm, welcoming lower level with smooth walls, quality cabinets, and soft LED lighting?ideal for family nights. They cleaned up each day and finished on schedule. Truly exceeded expectations."

"This company is built internally the right way. Extremely professional and everything is in house. I repeat...IN HOUSE. If you have ever dealt with a remodeling company that employs outsourced labor, it can be a mis-quote nightmare. Other companies pointed me to handy men for this job not realizing I might need or want more than that in the future. Thank you"

"⭐⭐⭐⭐⭐ Jason did an absolutely fantastic job on our home remodel! He completely remodeled our kitchen, helped expand the kitchen space, installed new flooring throughout the house, painted everything, replaced all the trim, and did a full bathroom remodel. The quality of his work was amazing, and his attention to detail really stood out. He was super easy to work with, communicated really well throughout the entire process, and made sure everything was done right. We couldn’t be happier with how everything turned out! Highly, highly recommend Jason to anyone looking to remodel their home!"

Basement Remodel FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.
