"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"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."

"AES Builder & Home Improvements Inc. was absolutely amazing to work with from start to finish! They remodeled our original kitchen, and the results are beyond beautiful. From our very first meeting to the day we spent picking out custom design materials, the entire process was organized, collaborative, and enjoyable. Their coordination and communication throughout the renovation were top-notch! Every contractor who came into our home was professional, respectful, and genuinely cared about their work. They answered all of our questions and kept us informed every step of the way, even when there were small delays. The quality of the craftsmanship truly shows, and our new custom kitchen makes me smile every single time I walk in to cook. We couldn?t be happier with how everything turned out. If you?re considering a remodel, I can?t recommend AES Builder & Home Improvements enough! Thank you to Stephen, Shawna and the entire AES team!"

"In 2017 my townhouse was remolded by Northstar Company. I signed the contract, left my house keys with Chris Marshall and left to snowbird for the winter in Florida. Every day when Iâ m back in the house, I marvel on the professional job done. Three years later, Iâ m still getting positive feedback on the remodel. Recently, we noticed the bathroom wall had black mold. I called Chris and he immediately responded to troubleshoot. On a rainy night, he stood on my handrail to look for the leak. We found the problem was caused by water leaking from my neighborâ s roof after cutting a hole in the upstairs ceiling. After his crew, fixed the neighborâ s roof problem and the termite contractor did his work, the ceiling was patched and painted along with the bathroom wall. It looks brand new. Iâ m writing this review to relay that this is a contractor that you can trust even after the contract is completed."

Basement Remodel FAQs, answered by experts

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Yes, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.
