"John and his team (Sal and Billy are just some of the team members) turned our dark, musty basement into a masterpiece! What once looked like a dungeon is now a bright, cozy space where I actually want to spend time. I thought the only thing our basement would ever be good for was hiding holiday decorations and junk, but now it’s a whole new level of livable. John made the process so easy and stress-free, always ready with a solution to every challenge. His crew worked with such precision that even the drywall looks like it belongs in a museum. Highly recommend, if you're thinking of remodeling your basement, just call this company. Your basement will thank you!"

Basement Remodel questions, answered by experts

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

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.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
