"Very happy with the basement. Work actually started 2-3 weeks earlier than expected. We were told the job would last about 4-5 weeks. Basement work was completed in about 4 weeks. Very professional. No worries about whether the plumber or electrician would be available. We discussed small changes to the layout (e.g., where the sink in the bathroom would be located) and everyone was very accommodating."

We are a General Contracting firm serving central and southern Vermont and New Hampshire since 1984. We offer a variety of construction services from design / build to working off your plans. We can work with you from concept to completion. Our seasoned construction team consists of estimating, project management, on and off site supervision, carpenters and mechanics. www.wrightconstruction.com

"I had serious water problems in my basement, and a crumbling foundation. The concrete block foundation had lost a lot of its grout and was bulging dangerously. Wright straightened the wall, installed French drains on two sides of the house, insulated the interior walls and ceiling of the basement, and installed a thick plastic vapor barrier on the floor. They poured about four inches of cement on the floor and installed a heater that will keep the temperature above freezing in the basement. This makes it easier to turn on the water and to heat the upstairs if I come up in the winter. The cost was about $40,000. I was very pleased with Wright's workmanship, responsiveness and the quality of their staff. I would recommend Wright without hesitation to anyone with an engineering problem."

Basement Remodel questions, answered by experts

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.

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’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
