"We are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"If you are in need of home renovations or home repairs, S&J Remodeling is an AWESOME company to call on. We are extremely satisfied with their work! Following a hot water heater blowout that resulted in six plus hours of continuously running water, and knee-high water damage in our basement, we were in need of major repairs; S&J Remodeling best fit our request for proposal requirements, of which included basement remodeling, kitchen repairs, and interior / exterior painting and patching. S&J Remodeling’s pricing was competitive, and winning consecutive “Angi Super Service” accolades for 15 years running was definitely a plus!!! Their customer service and genuine friendliness is praiseworthy, certainly a quality seldom found. Stacey and Jerry’s program coordination, task execution management, responsiveness, and professionalism were instrumental in ensuring effective communication with Oscar, the on-site supervisor and myself. Their efforts led to well-scheduled and well-done task execution, allowing my wife to fulfill her 9-5 job responsibilities, and my family to maintain a high-level of comfort throughout the renovation and repair process. I will definitely call upon S&J Remodeling for any future home renovation or repairs. I recommend that you do the same!"

"Melvin is a hard worker who always showed up on time, and completed the job as promised, and for the agreed-upon amount. He is cheerful, takes proper precautions to protect the home, then cleans up after himself each day. We gave him the difficult task of working around the very tight schedule of the plumber, the electrician and the granite installers, for our kitchen remodel. He did a terrific job, and we would definitely hire him again."

"The Proposal: Our salesman, Stephen, was very easy to talk to, responsive, and accommodating. When he didn't know the exact answer to something he was straightforward about it and made it a point to find out whatever it was. About the Professionals: The installers worked quickly and efficiently in oppressive heat, and finished their work in 1 day. Communicative and friendly. The Product: They appear to be good quality doors. Our only complaint is that our patio door came without its screen, or the key lock that we ordered to go with it. The screen on the front storm door became loose shortly after installation. This seems to be the manufacturer's error, and not AES's. A representative from the manufacturer (Alside) came to fix the issues after the fact. While it did take several weeks to get that sorted, it was still a positive experience working with the Alside rep; he was able to make a number of adjustments to the patio door that had it working even better than before, and repaired the storm door screen quickly. The Schedule: Our patio door was an odd size, so we had to wait an extra month or so, as their manufacturer (Alside) was backed up with orders. Props to our salesman Stephen for identifying straight away that we had a non-standard door size and accounted for it in his estimate, so we had no surprise costs. We also had to wait a fairly long time from contract signing to installation, due to their installer's busy summer schedule. AES was straightforward about this, though, and since we did not have a pressing deadline, we were ok with it. It was worth the wait. In summary, we have two new great-looking entrances on our townhouse, a sound investment. I would choose to work AES again because of their efficient installations and good communication, even if they are not the cheapest show in town. I've actually contracted them already to do work on a new property (kitchen and bathroom remodels), so I will be posting about that in the near future."

Basement Remodel FAQs, answered by experts

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.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.
