"I hired Bob for our basement remodeling project and thatâ s the best decision we took. He is such a perfectionist with his job, gives right suggestions on what needs to be done, not at all money minded, and mainly manages work to be on time. He returned back to work immediately after his surgery just to meet the deadline. We are more than happy with the outcome. I sincerely recommend Bob for any work he is capable of doing and worth the decision. In fact, I kept pinging him for more suggestions even after the job is done and he is very responsive. So thankful that we were able to find Bob through my friend and he is a highly recommended person for any remodeling job."

"I cannot say enough about these guys. Their prices were reasonable and about average compared to other companies. The owner, Dave was great to work with, he kept us updated on a daily basis, and was there every morning to look things over and help get the guys set up. The workers were there at 7 am every day. Work was done well within the given timeframe. Everything was left clean each day. They built a bedroom in our basement, and gutted and remodeled a bathroom, we couldn’t be happier with both projects. Very professional, highly recommend."

"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."

"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!!"

"I hired Loja Renovations to assembly a number of furniture I bought online that was very difficult to put together. They came and quickly assembled them with ease. They're very skilled and efficient. Apart from the reasonable cost, I was particularly impressed with their professionalism, their show of care for the customer and their respectful attitude. I definitely plan to use them again."

"The bathroom remodel was done beautifully. Anthony & his crew were very professional. Arrived on time everyday & put in a full day. I noticed he even was concerned about making sure everything was clean when leaving each day. His price was reasonable & we are going hire him again."

"Ryan from R&D is an true and honest guy. He won't give you the runaround, he won't try to talk you into something you don't need, and he and his crew are just artists when it came to remodeling our bathroom. We chose the inventory and R&D made it happen. Complete tile work of our shower and floor came out beautiful. I'll admit, it was a tough bathroom to remodel because the ceiling wasn't dormered. So, it made it a bit harder to tile due to the angles. But they made it work. They, also, helped outsource companies that were right in our price range from doing work on the shower door and counter top for the vanities. I highly recommend R&D and I think you should consider them for your next project."

"Anthony of All Precision Home Improvement did an excellent job at my home. He constructed a extension/dormer for an additional bathroom. He and his crew arrived early in the morning and did a maximum days work each day. Anthony was attentive to my requests and did his utmost to satisfy my specifications. The ultimate result more than met my expectations and therefore I would highly recommend All Precision Home Improvement to anyone looking for a reliable and efficient contractor."

FAQs for basement remodeling projects in Medford, NY

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
