"I contacted Remodeling Plus to give me an estimate for remodeling a basement, which entailed creating 1 bedroom, 1 bathroom, and a creating walls for a general purpose area out of the basement space. I am extremely glad I choose Remodeling Plus for several reasons. Bill, the owner of Remodeling Plus, and his colleague, Mark, have a great attitude. After working with several different tradesmen, it is a pleasure to work with people who want the customer to be satisfied and good to great lengths to ensure their satisfaction. For example, after I had carpet installed, he was there the same evening to finish trimming the doors so they wouldn't drag on the carpet. Bill provided great guidance on the project. His initial estimate for the project was quite accurate. The project cost more by the end because I made changes to the scope of the project. Bill recommended several good contractors to perform the electrical, drywall, and HVAC work. He also recommended working directly with my local municipality for the permitting process for speed of response by the municipality and cost. He also made recommendations of how to lay out the space in the bathroom based on his experience and the constraints of the space. His many years of experience in carpentry and home remodeling shows in the quality work he performs. For example, we had sliding doors installed for the closet built for the bedroom. Bill took the time to trim the sliding doors to fit around the base molding so the door fits flush to the wall instead of leaving a gap between the wall and sliding door. He also trimmed the doors up for the short basement. His knowledge and experience helped as the project grew and changed. He was able to fill in the floor with concrete after the plumber broke up a 30 foot long, 2 foot wide trench for the new sewer line. He was able to install 2 new basement windows into slots that had weird angles and require building a new frame for it. He can perform plumbing and electrical work if building permit is not required. I have lived in the remodeled space for about 1 month. It is hard to imagine what the space looked like before. The space is comfortable, well laid-out, and very functional."

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.
