"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."

Basement Remodel FAQs, answered by experts

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

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.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.
