How Much Will It Cost to Finish Your Basement in 2022?

In the Portsmouth, NH area, basement finishing and basic interior remodeling average around $125 per square foot. Renovation costs may be even higher for upscale basement remodels in New Hampshire. The amount you’ll actually pay depends on the current condition of your basement, your personal style tastes and your plans for the space.

Basement Remodel Cost Factors

If your basement is damp and drafty, we’ll need to find the source of the moisture and correct the problem before we finish the space. This might include re-grading the soil around your home, adding a waterproof vapor barrier, installing a French drain and sump pump, and treating moldy areas.

Do you want to add a wet bar, kitchen, or bathroom to your basement? Electricity and plumbing costs will raise your total costs, as will increasing the size of windows, adding a patio door to create a walk-out basement, and extending the heating, venting, and air-conditioning system (HVAC).

Generally, open-plan finished basements cost a little less than renovations that include dividing the space into several rooms. If you can are wanting to add a half bath in your basement, it will typically increase the cost by around $30,000. 

"We recently priced a basement in New Hampshire that had a 1/2 bath, LVP flooring, a drop ceiling, independent heating and cooling zone, new finished hardwood stairs and a few other minor add-ons. The basement area was 1100 square feet and it came out to around $137,000. If you upgrade to a full bath with tile shower, custom built-ins, and hardwood floors, your basement remodel cost could hit $175K easily."

The attic is the ideal place to create bedrooms for you, your children, or your guests. Depending on the amount of space available, you could add a luxurious bathroom or create a cozy bedroom seating area with a bird’s eye view of your backyard. Height can be a concern in homes in the Portsmouth and Seacoast areas. If your attic isn’t high enough for a bedroom, a playroom for the kids may be a better option.

Attic Conversion Costs in NH and the Seacoast Region

Wondering how much you’ll spend to convert your attic? In the New England area, attic conversion starts around $40,000 but can get as high as $150k+ due to potential structural complexities, the size of your desired space, and the level of finishes you choose.

You’ll spend more if you need to reinforce or replace the floor joists or rafters, add plumbing and electrical lines, or install new stairs, windows, or skylights. Attics tend to be cold in the winter and hot in the summer. Extending your HVAC system will increase your budget but is a must if you plan to use the attic year-round.

The quality of the finishes and products used in your attic conversion will also affect the cost. For example, you’ll pay more if your attic conversion includes inlaid hardwood floors or an oversized, luxurious steam shower.

Finding the right company to complete your attic or basement renovation is the most important step in the remodeling process.
