"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!"

"AES did a fabulous job remodeling my master bathroom. I needed a roll-in shower for my husband but did not want it to look like a hospital setting. They created a spa-like bathroom that is the envy of all my neighbors. They were professional and extremely responsive. They took time with my husband to ensure everything was at the correct level for him in a wheelchair. The tile work is amazing. I can’t say enough about how great the experience was and the end product is beyond my expectations. Thank you!"

"While we have not done the project the team was helpful with getting things sorted out until we are ready to pull the trigger. Mike Walsh was particularly helpful and responsive. When we do the basement we will reach out to Dewar again to actually perform the work."

"We hired Gomez Contractors for our master bathroom remodeling after seeing their great reviews on Google. I have to say that we are extremely pleased with how our bathroom turned out and how beautiful it looks. Santos and his team were extremely professional and accommodated all of our requests. They showed up on time every day for the duration of the remodel, and they provided high quality service. The company is affordable and Santos worked within our budget without charging any hidden fees. Everyone on his team is extremely friendly and we felt comfortable having them in our home working on our bathroom. We are definitely using them again for our next project. Highly recommend!"

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

Basement Remodel FAQs, answered by experts

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.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

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. 

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.
