"We interviewed three well-known companies in northern new jersey to finish our basement and could not have been happier with Magnolia. They are excellent communicators and super accommodating when there are last minute changes. The founder was directly involved in the project at multiple points."

    Basement Remodeling & Finishing Services

    Magnolia Home Remodeling Group is a basement remodeling contractor offering a variety of methods for wall insulation, drywall and paint concepts, lighting and flooring solutions, trim, basement baths, wet bars, and basement kitchens. We feel a finished basement can be a continuation or extension of the home's main living area, with a seamless transition to maximize the use of the new space.

    Even if it's currently a cold concrete space crammed with boxes and junk, the lowest floor of your home probably has loads of potential! Treat it just as you would any of the rooms aboveground, and it might become the most popular spot in the house—for much less cash than adding on. Basements are typically about one-third of the entire home’s available space (600 to 900 sq. ft. in the average home). In other words, most basements are underused.

    Let Magnolia Home Remodeling Group provide a free Basement Remodeling estimate and learn the ways to transform your basement into a work of art.

    Basement Kitchens and Bar Remodeling

    At Magnolia Home Remodeling Group, we offer basement remodeling and finishing services to turn your basement into an oasis for entertaining guests. Whether you would like a gathering place to watch the big game or a game room for your teenagers to get together with friends, we can help.

    You can add a wet bar or eat-in kitchen to your basement. Our services include kitchen, bath, and laundry installation, including plumbing, heating, and other essential options you may choose to build out your basement and add extra space to your home.

    Any time you create an extra space, you will add value. Whether you use it as an entertainment space, an additional kitchen, or an extended living area, the next owner may need it for a mother-in-law's apartment. Regardless, the new area will be valued and sought after.

    Basement Drywall, Insulation, and Paint

    Drywall for the basement works hand-in-hand with the insulation to keep cool air and moisture out. Our basement renovation experts know how important it is to have a continuous layer around the whole basement.

    When it comes to insulation, it’s much harder to put it in after a basement is finished. If you have a team like ours that does quality work on the insulation around the whole perimeter of the basement, it isn’t as necessary for inner-wall closets and bedroom walls. Every insulation has an R-rating. The higher the R-rating, the better it will be at keeping moisture and cool air out of your home.

    We also offer painting services. This finishing touch is just as crucial to our team as it is to you. We know that you want to see clean lines and sharp corners. You can transform your existing basement space with a fresh paint job.

    Basement Flooring

    Our pro team at Magnolia Home Remodeling Group offers various basement flooring options, including luxury vinyl plank, tile flooring, engineered hardwood, carpet, laminate and more. When choosing basement flooring, you may want to steer away from hardwood that is susceptible to mold and mildew. Carpet pads are great if you protect them from moisture.

    Hiring an expert basement contracting team, like Magnolia Home Remodeling Group, will eliminate design or installation mistakes along the way. Our experienced designers and installers will use industry knowledge to renovate the basement of your dreams.

    We aim to provide you with comfortable, easy-to-clean, durable options for flooring in your basement. Basements can have heavy traffic with parties and family gatherings. We can offer materials that will clean up nicely and swiftly.

    Basement Waterproofing Services

    Before any basement remodeling project begins, it's worth checking for signs of moisture. Musty odors, damp or discolored walls, white chalky residue (efflorescence), peeling paint, or standing water after a heavy rain are all signs your basement may have a water problem even if it looks dry most of the time. Left unaddressed, moisture can damage new flooring, drywall, and finishes long after your renovation is complete.

    As part of our basement remodeling services, Magnolia Home Remodeling Group offers professional basement waterproofing to protect your investment before we build anything on top of it. Depending on what your space needs, our team may recommend a sump pump installation to manage groundwater, vapor barriers to block moisture from passing through concrete walls and floors, French drains to redirect water away from the foundation, or crack sealing to close off points where water is getting in. We'll walk your basement with you, identify the source of any moisture issues, and recommend the right combination of solutions for your home.

    Waterproofing before finishing isn't just a precaution, it's what makes a finished basement last. Skipping this step is one of the most common (and costly) mistakes homeowners make, since mold, warped flooring, and damaged drywall are far more expensive to fix after the fact than to prevent up front. As a basement waterproofing contractor with over 30 years of experience in New Jersey homes, we build waterproofing into the plan from day one.

    Basement Wall Panels

    If your basement's in decent shape and you just want it finished without the whole drywall process, wall panels are usually the better move. We install basement-specific panel systems built to handle the humidity and occasional dampness that come with any below-grade space.

    They go up right over concrete or block, usually no furring strips needed, and most come with insulation already built in. Less labor, faster job, and the basement actually holds heat better once it's done.

    Panels aren't the answer for every basement, though. If there's an actual water problem, we'll want to fix that first - that's what the waterproofing section above is for. But if your basement's mostly dry and you just want it to look finished without a full framing job, panels are usually the quicker and cheaper way to get there.

    Not sure if panels make sense for your space? Get a free estimate and we'll help you choose the best wall system for your project.

    FAQs Frequently Asked Questions

    Q.

    How much does it cost to finish a basement in New Jersey?

    A.

    It depends mostly on size and what you add. On recent projects, a standard 600 to 800 sq. ft. basement has run $50,000 to $60,000, and larger basements up to 1,200 sq. ft. have run $60,000 to $80,000.

Your price is set in your written estimate after we see your space.

    Q.

    How do I plan and design a basement remodel?

    A.

    Basement renovation planning is an involved process, so it helps to get organized. Begin by determining how you want to use the space. Will it be an entertainment area, extra bedroom, or home gym? Next, evaluate structural elements such as the ceiling height, plumbing, and electrical systems. This will help you to come up with some initial design ideas. At this stage, it can be helpful to consult a professional basement remodel contractor. They will be able to provide detailed floor plans and design options that align with your goals, budget, and the limitations and opportunities of your space.

    Q.

    Do I need permits or special approvals for a basement remodel?

    A.

    In most cases, yes. We pull and manage the permits and inspections for you. Each municipality is slightly different, but New Jersey has strict basement building codes, and most basement remodeling projects require permits, particularly if you’re adding electrical outlets, plumbing fixtures, or altering load-bearing walls. Check local permit requirements, and work with a licensed basement renovation contractor to ensure you meet all basement building code requirements.

    Q.

    How do I address moisture or water issues before finishing my basement?

    A.

    Proper waterproofing and moisture control are key to a successful basement remodel. It is important to identify and fix any leaks or cracks promptly, install a sump pump if necessary, and consider using vapor barriers and insulation to minimize humidity. A good basement remodel company can offer basement waterproofing tips and help to diagnose and correct water-related problems before finishing the space.

    Q.

    Can I add a bathroom or bedroom in my basement?

    A.

    Yes. We add bathrooms, wet bars and bedrooms, including the egress windows a bedroom needs to meet code.

    Q.

    Can I finance my basement remodel?

    A.

    Yes. 100% financing is available, subject to credit approval.

    Q.

    Who will I be working with?

    A.

    One project manager runs your job from start to finish, and one of our owners stays involved. You’ll always know who to call.

    Q.

    Why should I consider remodeling my basement?

    A.

    Remodeling your basement can significantly expand living space within your home without altering its footprint. Whether you need a family room, home office, additional bedroom, or guest suite, transforming an underutilized basement enhances functionality and gives you additional usable square footage. And basement remodeling benefits do not stop there; a good basement remodel also increases your home’s overall value when the time comes to sell.
