"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"I was looking to completely remodel two of my bathrooms (demolition job). I hired Belmax (Maksim) based on reviews and the estimate for the projects (i.e. $15K). I could not have been any happier with the work that Max and his guys performed. Max is very professional, detail oriented, and the quality of his work is EXCELLENT. Living in my house for over 15 years I have never been more satisfied with a contractor. He is very transparent and trustworthy, keeping me informed of any decisions/deviations from the original plan. The project took slightly longer than expected but not due to any fault of the company. There were some "unexpected issues" with the main bathroom that caused the project to take slightly longer. Max and his team was here every day working. There was very good communication and he kept me updated throughout the entire project. I was so impressed and happy with m bathrooms that I hired him for additional work in my dining room and will be reaching out to him next year when I am ready to remodel my basement. EXCELLENT JOB BELMAX!!"

"My husband and I are beyond grateful to All-Star contractors for doing an excellent job on finishing/remodelling our basement. We never imagined that our basement will look this good despite the small size (we live in a townhome). Every space was made functional. Bill (the contractor) is very fair, always listen and give recommendations as needed. The price is appropriate for the excellent work done. Bill's crew is very hardworking and takes pride in his work - making sure that we will be pleased and always asked if there is anything or issue that needs to be addressed. We are in the process of lining up our next project with Bill. We will definitely not settle for another company for any work we need whether it is something minor or major. If you are looking for someone trustworthy - we will definitely recommend Bill without a doubt."

"Mr. John O. arrived on time and alerted me prior to his coming by phone. John went around the basement and inspected the walls and windows for moisture penetration, and signs of deterioration. He listened to my concerns and wrote a report and recommended an indoor french drain installation based on his professional judgment of the situation.
I received the report with a schematic of my basement and his assessment as a pdf on email. He included a detailed estimate for the work proposed.
I feel that I got a report and an hour of evaluation for $49 and it is fair.

Basement Remodel FAQs, answered by experts

Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

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.
