"We just had our basement finished. Not re-finished but finished for the first time. The house was built in 1924 with a dirt floor in the basement and low hanging pipes, overall a very challenging job. We wanted to turn it to a family room with a full bath, laundry room, closets, etc. Joe's guys (Chico and Javier) did a fantastic job. They are knowledgeable, thorough, thoughtful, and creative. We would recommend them to anyone without hesitation."

"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."

Customers say: Quality work

"This is an honest and reliable company. They took good care of the rest of the house while remodeling was underway. They added extra tasks which became apparent once the job was started. I would recommend them to anyone. I have hired them for several other projects."

"Ed and his crew finished our basement. He was great to work with and pricing was very competitive. The work they did was beyond our expectations and we were extremely satisfied with the finished product. Ed also did a remodel on our main bathroom. My wife couldn't be happier! We would highly recommend Galaxy Construction for your home improvement."

Basement Remodel FAQs, answered by experts

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

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.

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.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

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
