Highlights
It takes an average of 5 weeks to finish a basement.
The basement size and intended use are two major time factors to consider.
Subcontractors and inspections can add weeks to your timeline.
Finishing a basement takes a lot of work, from framing in front of your concrete walls and roughing in the necessary utilities to drywall prepping, painting, and adding finishing touches. In this guide, we’ll explain how long it takes to finish a basement and discuss some factors you should consider when determining your timeline.
Time It Takes to Finish a Basement
It takes about three to eight weeks to finish a basement, but it’s not uncommon for the project to take as little as two weeks or longer than 12 weeks, depending on the speed and availability of the contractor you hire.
There are quite a few steps you’ll need to check off in order, and completing any one of them earlier or later than expected can affect the timeline. Some general steps include the following:
Framing: The first step is framing in front of your concrete walls. In some areas, contractors take extra precautions to build a moisture-resistant bridge between the two to prevent rotting. On average, framing will take around three to six days.
Utility rough-in: Next, your contractor will rough in utilities, including electrical wiring, plumbing lines (if applicable), and connections for heating and/or cooling equipment. The average timeline for this step is three to seven days. This process can take longer if scheduling with subcontractors is necessary. It could be just one to two days if you only need electrical wiring.
Insulation: Insulation can take between one and three days, depending on the type of insulation you need and whether it requires a moisture barrier.
Drywall installation: Expect the drywall installation to take between five and 16 days, which includes installing the drywall, taping, and spackling, as well as drying time for the spackle.
Doors and trim: Installing doors and trim should take between two and six days. This timeline will depend on the number of doors and trimmed-out windows and could be longer if you also want crown molding throughout the space.
Painting: Painting a finished basement should take between two and four days. That includes prepping the space, two coats of paint, and the drying time for each coat.
Flooring: Installing flooring typically takes two to four days. This step can vary based on the type of flooring, especially if you need a subfloor underneath the primary flooring material.
Fixtures and finishing touches: Installing switches, outlets, and electrical fixtures and adding any finishing touches should take between one and five days, largely depending on the complexity of the space you want your contractor to finish.
Factors That Affect Your Timeline to Finish a Basement

As you might guess based on the large range of standard basement finishing timelines, there are quite a few factors that can affect your project duration.
Basement Size
As is the case with any home improvement project, the size of your basement will play a role in the project timeline. Larger basements demand more labor at every step of the way, so the larger your basement is, the longer it will likely take to finish.
The time estimates above are based on a standard 1,000-square-foot basement, so larger basements will likely take longer, and smaller ones could take significantly less time, on average.
Utility
The time it takes to finish your basement also depends on how you intend to use the space and your basement remodel ideas. For example, if you just plan on doing some light entertaining in the basement and you don’t need to add plumbing fixtures, you could instantly shave a few days or even an entire week off of your timeline.
On the other hand, if you plan on using your basement as an accessory apartment, installing a full bathroom and kitchen could extend the timeline by several weeks, not to mention the likelihood of the additional utilities and fixtures increasing the cost of finishing your basement.
Desired Finishes
In the time estimates above, we’ve included one to five days for finishing touches, but this could increase significantly, depending on your desired finishes.
For example, if you want custom cabinetry installed for storage or to build a kitchenette, you could be looking at several weeks of added time. If you prefer real hardwood flooring over a subfloor, you might be looking at several more days of preparation before your contractor completes the flooring step.
While upscale finishes will usually take longer, they could lead to your finished basement adding more to your home value, so they can be worth it.
Contractor and Subcontractors
If you hire a basement remodeling specialist near you who uses subcontractors to get the job done, you could be looking at significant delays in scheduling each portion of the work your contractor subcontracts out. The more subcontractors your remodeling specialist uses, the more likely you are to add multiple days or even weeks to your timeline.
Additionally, the speed at which your main contractor works and their general availability will play a part in how long it takes to finish your basement.
Inspections
Another important thing to consider is basement code requirements. Depending on where you live, you might need building permits to do any finishing work, while some municipalities might only require permits for installing utilities in the space. The permitting process can add days or weeks to your timeline, as you might need to wait for the proper inspections before work can continue.
Finishing a Basement Yourself vs. Hiring a Pro
Finishing a basement entirely on your own is not a DIY-friendly project. Not only will it likely take significantly longer to complete if you do it yourself, but if not done correctly, it could cause major issues with electrical, plumbing, and moisture damage. In the majority of cases, knowing who to hire for a basement remodeling project will save you time and stress—especially when it comes to electrical and plumbing work.
However, there are some simple aspects of the project that you can handle on your own, such as painting drywall or installing drop ceilings. These are rewarding DIY tasks that can shave a bit of money off your overall budget.
Frequently Asked Questions
You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
Yes, finishing a basement is worth the money in most cases. Although the project is a relatively expensive one, finishing a basement adds usable square footage to your home and typically increases your home value. Many times, your finished basement will add value that’s equal to or greater than the cost of finishing.
