Basement Remodel questions, answered by experts

Project timelines vary significantly, typically from weeks to months, depending on design complexity and active permitting processes.

Yes, you’ll use a macerator pump to install a basement bathroom without breaking concrete. The purpose of breaking into concrete is to connect the drain pipes to the main sewer line. But a macerator pump will bypass this step and break up solids until they are soft enough to pass through a discharge pipe. That pipe will carry the waste to the sewage line.

It costs an average of $32,000 to finish a basement, and most projects total between $15,000 and $75,000. If you just want to make the space look a bit nicer and don’t need to convert the basement to legal living space, you could spend as little as $3,000 to install drywall and flooring. On the other end of the spectrum, your costs could rise to $100,000 if you want to make structural changes to the space, repair existing structural damage, waterproof your basement, or install a kitchen and bathroom along with living space.

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. 

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.
