"Tim and his crew are amazing. They built me an awesome deck!! From the beginning of the project to end I was thoroughly impressed. His quote was timely and fair. I’ve heard of so many horror stories about contractors so i was so pleasantly surprised at how great this experience was. The work began quickly and the workmanship is incredible. These guys know what they’re doing. Tim is so professional. He is prompt, he communicates everything in detail and really pays attention to detail in the work. He’s also a really nice guy. His crew is polite and work so hard. They’d get here and never stop working. Maybe 5 minutes to eat a sandwich. I plan to hire Tim for future projects. No question about it! Highly recommend."

Basement Remodel FAQs, answered by experts

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.

If you’re not sure which method of raising the ceiling is best for you, here are a couple of considerations to help you make that decision. A professional ceiling company will be able to help you determine the best option for your home.

How long you are planning to live there: although raising the basement ceiling will increase the value of your home, if you’re planning to sell the house, then go for raising the house.
The condition of the foundation: to lower the floors, your foundation has to be intact whereas raising the house will allow you to restore the damaged foundation.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

Envision the type of bar experience you'd like to create for your guests. For example:

Does your basement have enough finished space for bar stools or seating?
What type of additional lighting would set the tone for the room?
Are there basement windows or an HVAC system?
Do you need new plumbing in your basement for a proper wet bar?
Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?
