"Shepherd Contracting remodeled both of my bathrooms and installed new flooring throughout my entire house. Thomas was awesome! He was respectful, easy to work with, and offered way better pricing than other contractors I got estimates from, without compromising on quality. The work turned out 10/10, and I?ll definitely be using them again!"

"It was great working with Sean on our remodel. He assisted us in removing a wall between our kitchen & living room and reinforced the space with a beam. He built out a laundry closet complete with gas/electrical hook ups, etc. He is calm, collected and knowledgable and we appreciate his work everyday."

"Pretty well. Cesar and his crew are masters at drywall repair and matching texture pattern. The work took a week which was little longer than originally expected but we added some items to the list. After the crew was finished painting and left, we noticed some spots that were missed (hard to see except in the morning light). Cesar was more than happy to come and fix the problem in a very timely manner. Cesar wanted to make sure we were happy with the job and went out of his way to make it all good."

Basement Remodel FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.
