"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!"

"Excellent work. We used JAG for a small bathroom remodel. Walter listened to our ideas, made great suggestions and executed the final product to perfection. We love our new bathroom and would definitely use them again for future projects."

"I highly recommend US Home Remodeling. Bob was a pleasure to deal with and the team that he has is fantastic. They were on time everyday, explained what was being done for the day and got right to work. Our project was delivered on time and on budget. The team went above and beyond and were incredibly professional. My wife and I are already planning out our next project. It is not often you find a team as dedicated to excellence as US Home Remodeling. 5 stars for sure!"

Basement Remodel questions, answered by experts

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

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.

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.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.
