"Bob was excellent throughout the entire process. We had a completely unfinished basement and Bob was quickly able to inspect, price, and create a beautiful basement which included ample closet/storage space, an office, bathroom, open concept laundry room, walk-in pantry and lounge area. Bob was by far the most responsive and cost conscious of any contractor I was trying to work with. Even when we made changes in the middle of the renovation, Bob was quick to pivot and provide exactly what we wanted. Highly recommend."

"I first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"Jose and his team were the best team I have ever had work on a job in my house. Jose went WAY above and beyond to make sure we had our basement back in order in a timely fashion. He was willing to work after hours if needed to help get our finished basement back after we had suffered a sewage leak and had to wait until mitigation was complete. A 3-4 day job was complete in 2 days! And one of his workers, Carlos, from the second day stuck around to help me get the heavy and large items back into the basement. There was a previous review that said Jose was very emphatic to their needs and that is so true. That review actual was what made me give Jose a call. I wish there was a word better than highly recommend. Thank you Jose and your entire team!"

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

"This is the second time I have worked with Stars & Stripes. They were even better this time around. Always punctual, communicated throughout the entire job on the status, assisted with any questions and concerns. Not only were they the lowest estimate we received, but their quality of work was top notch. They completely transformed our basement to reach its full potential. Couldn’t be happier with their work and recommend them for any of your home remodel needs."

Basement Remodel questions, 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.

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.

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.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
