"Overall good job with finishing my basement. i really like my basement overall after i installed carpet from Home Depot and home-theater system from Best Buy. i really appreciated them picking up the selections for the basement bathroom from Home Depot. Things that could have been done better: * I had to replace the closet fixtures, probably because they were fixed on the dry wall. * would have been better if i had choice with the shower inside the basement bathroom."

"I consider myself a little more than a novice on general construction when it comes to studding and drywall. I am also a bit of a perfectionist. I needed support to help me studd my unfinished 1700 square foot basement in a new construction home. After calling over a dozen contractors who would either charge me ridiculous prices or tell me that they only do projects like this from start to finish, I met Jordan from JWC and he agreed to take on my project for a reasonable price. I was a little apprehensive at first because his was a young business. Folks, let me tell you. Jordan and his crew came in and absolutely KILLED IT! After three days of back breaking work I was left with a perfectly square and plum studded basement. Throughout the job, Jordan and his team were friendly and courteous to my family and I. More importantly they tackled the work with the focus and know how of a 20 year business. I was floored by their efficiency and ability to navigate the challenging areas like the knee wall I requested along the back wall. I could not be happier with the professionalism and work that Jordan with JWC provided. All of which was provided at a reasonable and honest price. Thanks again JWC Recommend 100 out of 100!!"

"I had planned on finishing our basement myself. Matrix completed a basement for my neighbor so we called for a design/estimate, I am glad we did they were professional, courteous and made themselves welcome guests in our home. They utilized the window wells to move materials as well as come-and-go, so there was minimal distractions to our day. My wife works from home and they were no bother. We were impressed with the materials they used and appreciated their design ideas. We were also able to negotiate items for us to complete to help lower the total cost. We would absolutely recommend to anyone looking to remodel their basement."

"We had Shire Group work on a remodel of a new office for us. They removed walls, framed in new doorways, and, in an ample space, created five new offices from the ground up. They asked questions that we never would have thought of. After completing the project, many visitors asked about their work besides the new offices. This shows how detailed they were; people could not tell new trim from old trim, removed doorways, moved light switches, and turned an old mailroom into extra space in our kitchen."

Basement Remodel questions, answered by experts

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.

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 average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

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.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
