Finishing your basement can add valuable living space to your home, but it can be a time-consuming project. Knowing the best time of year to finish a basement can shorten your project timeline, reduce delays, and even cut costs. Learn the best time to finish a basement and the pros and cons of tackling this project during each season. 

When to Finish a Basement

While it’s possible to turn your basement into living space all year round, fall and winter are often the best seasons for this project. Contractors are often much less busy during the colder seasons, and since finishing a basement is an indoor job, it can be done even in the middle of winter. Since you won’t be competing for your contractors’ time, you may be able to complete the job faster, have fewer delays in getting materials, and may even pay less overall for the project.

Factors That Affect Finishing a Basement

If you’re trying to decide between a finished and an unfinished basement and the right time to take on the project, consider the following factors that can affect the timeline.

Contractor Availability

If your project is extensive or involved, you’ll want to hire a pro to finish your basement who has enough time to complete the job. Spring and summer can be especially busy for contractors, so you may have trouble finding someone who can take on the job.

Exterior Work

There are only a few drawbacks to finishing a basement in the winter. You may not be able to waterproof your foundation in freezing temperatures, so that might be a good project to complete before the thermometer drops. Expanding window wells and adding egress windows or doors may also be more difficult in winter, so talk to your contractor to see if that will affect your project’s timing. 

Utilities

Installing plumbing, electrical, and other utilities may require coordination with multiple pros. During a busy season, it may be more difficult to get the work you need done on schedule, so you may be better off waiting until the weather cools down.

Materials

Materials may be more difficult to get during the spring and summer, when it seems like everyone is doing home projects. Waiting until the winter can mean easier availability and maybe even lower costs. 

The Worst Time to Finish a Basement

You can finish a basement any time of year, but you’ll be competing with a lot of other remodeling jobs in the spring and summer. Warmer months also tend to be busier and more active, so undertaking a big construction project may be extra disruptive when you have more going on.  

Cost to Finish a Basement

Finishing a basement costs an average of $15,000 to $75,000, depending on your basement size, the scope of the project, materials, permits, and labor costs. Finishing or adding a bedroom to a basement can add value to your home, so you may recoup your initial investment when it comes time to sell.

DIY vs. Hiring a Pro

You can save on labor costs by finishing your basement yourself, but it’s a big project that involves ensuring building codes are followed and utility work is done properly. Unless you have experience with this kind of construction, your best bet is to hire a local basement finishing contractor. A pro will obtain any necessary permits to finish a basement, follow all local building codes, ensure utilities are safely installed, and leave you with top-quality results.

Frequently Asked Questions

Finishing a basement can add value to your house by transforming an unused area into valuable living space. Finished basements can provide an average 70% return on investment (ROI), depending on your area and the type of basement. As long as you follow all local building codes, including installing points of egress, you may be able to count a finished basement toward your home’s total square footage.

Finishing a basement takes an average of five weeks, but can range from as little as a few days to several months or more. Your project’s timeline will be affected by the size of the basement, which utilities need to be added, how much additional framing and construction is needed, and more. A dedicated crew of workers will finish the job faster than a homeowner tackling it as a DIY project, so be sure to accurately estimate how long each step will take.
