"Spencer and Modo Renovations just finished a major renovation on our basement (adding a kitchen, bedroom, and bathroom), and the final result completely exceeded our expectations. Spencer is an absolute pleasure to work with. He is incredibly responsive, professional, and transparent about every detail of the process. His crew did an excellent job with attention to detail in the craftsmanship is evident everywhere you look, and they handled all the permitting and infrastructure smoothly. Spencer kept everything on track and made a massive home project feel entirely stress-free."

"We recently had a complete kitchen renovation and main floor remodel done at my parents' home, and I can’t express how pleased we are with the results. From the very start, William and Miguel made the entire process a dream. William was simply exceptional to work with. He went above and beyond to make sure we were happy every step of the way. Not only was he incredibly helpful, professional, and available at all times, but he also took the time to accompany us to the store to help select the best products, tiling, and appliances—all while keeping us within budget. His advice was spot-on, and his eye for detail was invaluable. Throughout the project, he provided regular updates and checked in frequently to ensure we were comfortable with the progress. One of the biggest challenges was navigating the different perspectives of not only my parents but also myself and my three sisters, all of whom were involved in the decision-making. William handled it all with patience, diplomacy, and a calming presence, making sure everyone was heard and at ease. His guidance was steady and reassuring as he led us through the process with a professionalism that truly impressed us. William has clearly put in the effort to build a top-notch team. He surrounds himself with respectful, hardworking individuals who value trust, honesty, and family as much as he does. It's clear that he genuinely cares about creating bonds with his clients and helping them transform their homes—and their lives. Miguel, the man behind the magic, went above and beyond at every turn. His craftsmanship is excellent—truly top-notch. He was kind, dedicated, and worked tirelessly to get things just right. He arrived early, stayed late, and even came on Saturdays. Despite the language barrier, he used Google Translate skillfully to ensure we were always on the same page. Throughout the project, he kept us informed and even handled extra fixes at no additional cost. It was clear he took great pride in his work, and his attention to detail showed in every aspect of the renovation. By the end, we genuinely felt like we had made new friends in William and Miguel. They did a fantastic job bringing our 1930s house—never before renovated—into a modern and beautiful state. They tackled everything from a complete kitchen demo down to the framing: new insulation, ceilings, floors, walls, appliances, cabinets, a partial wall removal to make room for a gorgeous kitchen island with pendant lighting, and the meticulous restoration of the original hardwood floors. They even went above and beyond after the project was finished, coming back to help us set up exterior security cameras. Their recommendations were spot-on, and they always had an eye for aesthetics while staying within our budget. We couldn't be happier with the transformation they've achieved, and I wholeheartedly recommend them to anyone considering a home renovation. Thank you, William and Miguel, for your hard work, kindness, and professionalism. You made what could have been a stressful project a truly enjoyable experience."
This was a larger bathroom with two accent walls, a tub and sauna shower with jetted shower heads, a custom-cut ceiling, heated pebble flooring, and a mini wooden walkway.
The client wanted a tub sitting on pebble stones with an accent wall, wooden look custom shelving, and a smart floating toilet.
The image showcases a contemporary stand-up shower featuring frameless glass doors that provide a seamless, open look. The interior is adorned with large marble tiles in a soft, neutral tone, giving the shower a luxurious feel.

Built-in niches provide stylish and practical storage for toiletries, while subtle LED lighting enhances the overall ambiance.

"I highly recommend Loja Renovations & Fine Carpentry LLC! Manuel and Fabian were professional, courteous, and did an outstanding job. They helped me with several projects in my home, including mounting two TVs, installing a shoe rack, hanging a very heavy mirror, putting up window shades, and installing several shelves. Everything was done carefully and professionally, and they were extremely helpful throughout the entire process. What I especially appreciated was how prompt and reliable they were. They came all the way from Corona, Queens, and arrived ready to get everything done. Their attention to detail and quality of work really stood out. They offer a wide range of renovation and carpentry services, and based on my experience, I would absolutely hire them again for future projects. It’s not always easy to find people who are dependable, skilled, courteous, and take pride in their work, so I’m very glad I found Manuel and Fabian."

"Al is very reliable. My Reno was complicated and involved some significant structural work. He was either on my job site every day or in touch with me by phone or text to keep me up to date on the work. This is not a guy who will go missing on you. Unlike others, he was great about making all required filings and getting all sign offs needed from the local Building department. He also worked very well with my architect. His carpenter, Louis, and his painter/plasterer, Johnathan were wonderful too. I would recommend him for future projects."

"Theo is absolutely wonderful to work with. He's an old school man of his word, as well as a talented contractor. His guys are skilled and fast. Very good carpentry, plumbing and electrical. He first finished our dank basement and turned it into a beautiful space, then moved on to gutting our kitchen and other upstairs details. Highly highly recommended. Besides being timely and competent, he quickly addressed issues that arose - a shower floor than needed to be pitched correctly, and some areas around a window they put in. We are continuing to ask Theo to work on projects at our businesses and will contact him in the future for any more home renovation we have."

Basement Remodel FAQs, answered by experts

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

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.
