"The good - Job was eventually completed and we are pleased with the outcome. I was impressed that most of the work was done by one guy when some tasks could clearly be done a lot easier with 2 people. They did stick to the quoted price. The bad - and maybe should be 2 stars for these. We hired them at the end of March 2024 with the project quoted to be completed by the middle of July 2024. It did not get completed until Jan 2025 and this is completely unacceptable. We got a call from the electricians that they used stating that he was not returning their calls and that they did not make the payment. Eventually by the time the project was completed they did pay for the initial install. I chose to pay the electricians myself for the completion portion and did not go through CWE for that because they lied to me about contacting the election to finish the project. They also rarely returned my calls. His worker would show up without notice that he was coming out."

American Home Remodeling is a family owned full service remodeling company where the owners are the people you talk to for your project from start to finish. You don’t get bounced from department to department like with the big companies. We are involved every step of the way including putting on our tool belts on most projects. We are very proud to be at the very top of the remodelers on Angie’s list. We are there by providing our clients with High Quality work at competitive pricing. Our clients' reviews speak for themselves. The people we work for always feel that they have received more than their monies worth when we have completed their project. We leave the project having made new friends, and always end up with a new good reference. We hope to add you to our continual growing list of happy homeowners.
"My wife and I recently relocated from another state and had some extra money to invest in our new home, so we decided to partially finish our basement. While searching Google for basement remodeling services, we found two options. One was a company specializing solely in basement remodeling, but after scheduling a consultation, I quickly realized it wasn’t the right fit—every little detail came with an added cost, and there were too many unexpected “oh, by the way” expenses. Around the same time, we reached out to American Home Remodeling while gathering quotes. Nick met me at the house, and I walked him through the space, explained our vision, and shared our budget. From the start, he was straightforward and even suggested a few alternative approaches that, while slightly increasing our upfront cost, would ultimately save us time, money, and maximize the space. After reviewing their proposal, we signed a contract and moved forward with the project. What I appreciated most was how well-organized and efficient the entire process was—each step had a purpose and was completed on schedule. Permits were approved faster than expected, and construction began just before Thanksgiving. Since we were hosting family for the holiday, Scott and Nick were thoughtful enough to coordinate the dumpster’s arrival so it wouldn’t be an eyesore for our guests. Once the holiday passed, work resumed seamlessly. The project progressed smoothly—plumbing was completed on time, followed by framing, electrical, drywall/paint, flooring, and carpentry. Every contractor assigned to the job was professional, punctual, and knowledgeable, always available to answer my questions if Scott or Nick weren’t present. I was never left wondering what if—a few times, I had ideas mid-project, and Nick always provided his professional opinion before executing them flawlessly. The entire project lasted about three months, though it likely would have been completed sooner if not for the holiday season. Regardless, everything was strategically planned and executed on time. From a financial standpoint, the payment structure was transparent, with a clear breakdown of what percentage was due and when, based on project milestones. Scott would send a simple notification when a payment was due, but work continued without delay—even before payments were received. There was never any pressure, just a well-managed and trustworthy process. Fortunately, we had the funds and stayed on schedule with our payments. Prior to the basement project, we had already taken on a few other home improvements, including painting the interior and closing off a wall to add closet space. We hired another company for that work, but in hindsight, I wish we had discovered American Home Remodeling sooner to handle those projects as well. Overall, we had a fantastic experience with American Home Remodeling. Their professionalism, organization, and expertise made this project stress-free, and we couldn't be happier with the results. Highly recommend!"

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:
Replacing insulation
Replacing carpet or other flooring
Adding heating and cooling
Adjusting or adding walls and doors
Altering or adding plumbing elements
If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
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.
Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:
Painting walls yourself versus including in the cost of the remodel
Installing light fixtures yourself
Choosing prefabricated fixtures, like cabinets, over custom ones
Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
