"We had a water leak in an upstairs bathroom that damaged a downstairs ceiling and the subfloor. He brought in his subs to replace the flooring, subfloor, toilet flange, sheetrock, ceiling, popcorn texture, and painting. Everything he did and all of his subcontractors were fantastic. Highly recommend Luke and his professionalism."

"I called Jeff to get his thoughts on some asbestos duct insulation in the basement of a house we were making an offer on. He was out with an appointment, but called back ASAP and asked for all the details, then walked me through what he would do in my situation. Incredibly, even though his livelihood is asbestos mitigation, he recommended I leave it alone (he said since there was so little asbestos, and the insulation tape was in good enough shape, it'd actually be worse to try and remove it). He was extremely courteous and knowledgeable, and even though his advice meant that I wouldn't be hiring him, he has my recommendation for anyone who actually DOES have an asbestos problem.

"It is a waste of money. The great majority of people are not going to find any value out of the service. If you need design consultation, you need a full service consultation. If you already have knowledge and experience, and you just need to get a few ideas, then you don't need to pay for that. You can just get a magazine or a book since you already have the knowledge of basic designs in your head or a little bit of experience. To have someone call you and give you information over the phone, you are not getting the personal service that you need. You may as well take the money $49 and apply it to something else like getting someone else to come out and give you the service that you need. Because, you are not getting much, you are not getting anything at all. They are going to have you do the work. After talking to them and I was talking to other home designers, I found out that that was a waste of time and waste of money. I gave them a C because they didn't fail at what they do but they don't offer any value for what they do. There's not much value to it. The cost was fair. They didn't do a terrible job and the cost isn't terrible, it was only $49. It just has a very low value. For responsiveness I gave them a B because they will answer your phone and answer your emails."

Basement Remodel FAQs, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

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.

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.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!

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.
