"Nick did an awesome job with our medicine cabinets. His work went above and beyond. When he noticed too-large gaps between the doors and frames, he drove all the way to the building supply store to get better-sized parts. Would definitely recommend him."

Customers say: True professional

"Quite a few years ago, Artie renovated our bathroom.  Not only did he do a super job, but he made so many helpful suggestions along the way making decision making much easier.  For example, he suggested the type of tub to install and ones to avoid.  He helped us order merchandise and we were able to get a contractor's discount! 
     Recently we wanted to add a stone grilling station and a gazebo to our yard.  Everything I shopped for, I did not like or it was way over priced.....Artie sat with me and helped design a BEAUTIFUL, river rock-blue slate grilling station.  Once again, he directed me where to get the grill, type of grill, what to avoid and what would look best.  He takes the time to listen and know exactly what the customer is looking for.  He made everything by hand and the result shows....We get so many compliments from it!  He is currently completing a Tiki Hut Bar/Gazebo........when it came to ordering the tiki hut straw for the roof, Artie took it upon himself to google information online and forward me what he had found.....this made it so much easier on my part!  The bar came out great!!!
     Not only is Artie extremely talented, but he is so easy to work with, is very professional,responsible and shows up for a job when he says he will.....when do you ever get that?????  I HIGHLY recommend Artie Derosa!!"

"Jose and his team were the best team I have ever had work on a job in my house. Jose went WAY above and beyond to make sure we had our basement back in order in a timely fashion. He was willing to work after hours if needed to help get our finished basement back after we had suffered a sewage leak and had to wait until mitigation was complete. A 3-4 day job was complete in 2 days! And one of his workers, Carlos, from the second day stuck around to help me get the heavy and large items back into the basement. There was a previous review that said Jose was very emphatic to their needs and that is so true. That review actual was what made me give Jose a call. I wish there was a word better than highly recommend. Thank you Jose and your entire team!"

"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."

"We hired Steven to redo our kitchen floor and install a countertop backsplash. Unfortunately, the project did not go as smoothly as planned. The workmen on the first day caused damage to an adjacent floor and did a poor job with the leveling. To Steven’s credit, he immediately acknowledged the problems and arranged, at his own expense, for the floor to be refinished and the leveling redone properly. What was supposed to be a three-day project stretched into months because of these complications, and during that time we often doubted his assurances that he truly wanted the work done right. In the end, however, Steven stayed committed. After many conversations and much patience, the job was completed conscientiously and to our full satisfaction. He also gave us a substantial discount to help make up for the delays and inconvenience. While the process was far more drawn out than expected, Steven ultimately stood behind his work and made sure the final result was high quality. He is a man of integrity who really stands behind his work. This is something to truly be valued."

Basement Remodel FAQs, answered by experts

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

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.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

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.
