"He hired Tom Harrop to install kitchen cabinets and a heater under the kitchen sink, vinal flooring, plastering in a small area, add ceiling lighting and a shiplap ceiling. Once the work was done I asked Tom to do a walk through and he refused saying he stood behind his empoyees work. Here are the PROs and CONs. PROs: 1.) work was completed in a timely fashion 2) they did a beautiful job on the shiplap ceiling and lighting. CONs: 1) The brand new white cabinets had some nicks requiring paint touch up. 2) Terrible job on the floors! Uneven spots, lengths are uneven at the edges, gaps showing, no finish work. Terrible job!! 3) plastering looks like it wasn't even done! And there is some peeling of paint on the plaster job. Terrible job!!! 4) we were promised and paid for an under the kitchen sink heater which we never received. Called multiple times with no response. Lesson learned, will never use Tom Harrop again!!"

Lux Renovations, LLC exclusive provider of the Owens Corning Basement Finishing System, has been serving New England homeowners since 2002. Our dedication to customer experience and satisfaction has won us Owens Corning's top customer service ranking nationally for the last 17 years in a row. Something like that doesn't happen by accident. We are committed to insuring that all of our customers describe their experience with us as "the best contractor experience I ever had". If you are considering a basement finishing project please allow us to show you how Owens Corning has changed the industry with this unique system. A free consultation and design is always available.

"Overall, the finishing of my basement went pretty smooth. The Owens Corning product, drop down ceiling, and flooring are all really sharp. In the beginning everything went fast and smooth with the framing and wall/floor/ceiling install being done within 2 weeks. There were some hiccups with minor imperfections, tv mount in wrong spot, etc. Those were fixed promptly. After that is when I ran into issues with other items in my contract that were not taken care of and the project felt forgot about. Just had some minor electric work, stairs to get carpeted, and didn't receive hanging clips yet. I had to constantly ask about these items and every answer would be "I forgot to ask or send the clips". I eventually got the items completed, but am not happiest that it took almost a month and constant reminding to get these items that should've been scheduled for during the project."

FAQs for basement remodel projects in Charlestown, RI

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.
