Q: Is it less expensive to finish a basement or add an addition?

• <div><p>It&rsquo;s less expensive to finish your basement than it is to build an addition to your home.

Q: Can you turn a regular basement into a walkout basement?

• <div><p>Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your <a href="https://www.angi.com/articles/basement-foundation.htm">basement foundation</a>, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.</p></div>

Q: Who do I hire for a basement remodel?

• <div><p>For most basement remodels, you&rsquo;ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. </p></div>

Q: Can barndominiums have basements?

• <div><p>Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you&rsquo;re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.</p></div>

Q: How much does it cost to make bigger windows in a basement?

• <div><p>Making a window in a basement larger costs an average of $4,200. You&rsquo;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.</p></div>
