Basement Remodel questions, answered by experts

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

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.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.
