"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!!"

"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."

"Dave A, of "Basement REPAIR SPECIALISTS", is someone you should have on speed dial. Dave showed up and thoroughly inspected the areas of concern. After examining the basement area he said he would like to look at the outside of the home. He took his time, commenting on yard drainage grade, gutters, and roof pitch. He said, "he would love to take the Job but he thought we should first take a much cheaper approach to repair our problem". Dave obviously is a man of integrity. We decided to take his recommendations. If we still have continued problems, Dave will be our contractor of choice. It's really nice to do business with a thorough and honest man."

Basement Remodel questions, answered by experts

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.
