"C&O Contracting owned by Bob Ouilette has a business of using poor materials, as a result his workmanship needs to be fixed within weeks. He then becomes overwhelmed faced with fixing everything from using rusting fencing to building in an air ventilator askew so its not facing the window. Then he finally takes the money and runs. Telling you he will come and fix it next week.... Meanwhile I had to get his hacked workmanship fixed properly by others."

No worries about whether the plumber or electrician would be available. We discussed small changes to the layout (e.g., where the sink in the bathroom would be located) and everyone was very accommodating."

"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

Basement Remodel questions, answered by experts

It costs an average of $32,000 to finish a basement, and most projects total between $15,000 and $75,000. If you just want to make the space look a bit nicer and don’t need to convert the basement to legal living space, you could spend as little as $3,000 to install drywall and flooring. On the other end of the spectrum, your costs could rise to $100,000 if you want to make structural changes to the space, repair existing structural damage, waterproof your basement, or install a kitchen and bathroom along with living space.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

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.
