"We called, Alex came out that afternoon, had a bid the next day for the screening. The next day he had a bid on the chimneys. He and a partner began the work and finished in a week. They cleaned up each day, and hauled away trash. Very nice to work with and very thorough. Yes, I would hire again."

"Kirt did a great job. He figured out how to straighten out the kitchen floor. Can't tell there was ever a hump there. Kirt and his partner showed up every day on time. Started the job when he said he would and kept the cost to the estimate. I was kept informed of what they were doing and how they were going to do it the entire way. They ran a couple days over the estimated time but they stayed here til it was finished. I love the job they did. My kitchen and bath look great

Basement Remodel FAQs, answered by experts

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

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.
