"Everything went very well. We sent Michael pictures of what needed to be done. He gave us a quote. We later asked him to come onsite to firm up the quote, which he did, and the price was the same. He stated he was booked some time out, but said he sometimes has cancellations. He contacted us and stated he indeed had a cancellation, so was able to start the next day. He started the work, even without a deposit, since it was short notice, and we were still away, out of town. We were trying to decide what to do for railing, and had captured quotes from supply companies for replacement aluminum or steel materials, but they seemed high. We asked Michael for his thoughts. He checked a hardware store for us, sent us pictures, and then sent us the part number/SKU's from the store. We paid the store directly, and he picked up the materials. The work is almost done, but all has gone great thus far, and we see no reason why it won't complete with great success."

"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

Basement Remodel FAQs, answered by experts

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

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.

Yes, you can install a summer kitchen or kitchenette in your basement. They serve similar purposes as outdoor kitchens, keeping the main floor of the house cool and providing another space to cook and congregate. Basement kitchens are also a worthwhile alternative for homeowners without much space in the backyard. They come with a few logistical questions to sort out, though, like ventilation and waterproofing.
