"No extensive renovation is easy to live with, but Scott and his crew made it as easy as possible. They are responsive and detail-oriented. They show up when they say they're coming and finish work within the time estimates--and the finished job looks great!"

"I originally hired LJ&A to remove some 30+ year old stucco siding and replace with new vinyl siding and fix any rot there might be. The project expanded to include structural repairs. There was a considerable amount of hidden water damage and rot to the building. Lional and his friendly crew expertly advised and corrected all of the issues including re-framing and installing two new windows, repairing a rotted sill plate, and a structural beam. They used quality materials and the workmanship was first rate. While these necessary extra repairs added to the budget, none of it was a surprise. LJ&A's bid was fair and all the added value work they did was outstanding. They didn't try to gloss over major problems or take advantage and inflate the price of the job. This company is communicative, honest, and very professional, best of all they treated us like neighbors. I will use them for all my projects and recommend them."

"If you are in need of a professional with vision and integrity, Robert is the only one to hire. After a basement flood, we interviewed 3 other companies, all of whom wanted an exorbitant amount for the project and also wanted to charge for a written estimate. Reliable, knowledgeable on all matters of construction, mindful my budget and a true professional. His work is meticulous and he leaves your home spotless every day. I got lucky and so will you!"

"I first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"Domenick is a professional craftsman. He kept to a tight schedule, always showed up on time and did a great job. He gave us creative ideas that would work in our space. Domenick and his team were pleasant to work with. From the moment they entered our home they worked a full day and showed up everyday. Domenick enjoys and takes pride in his work. We are extremely pleased with the final result. Our basement bathroom was transformed into an oasis with a spa feel. The main area in the basement and hallway leading to the basement was also transformed into a warm, welcoming living space. The work he performed in 3 weeks was: Build a new shower/tile with a design/create a shower bench/install shower panel/tile behind the vanity with the design trim/install the vanity/move plumbing, gas and electrical for the shower and vanity with light fixture/tile the floor/install a stackable washer and dryer/build out a wall to divide the storage area and heat unit/install a sliding barn door/paint the bathroom, main room and hallway up to the kitchen door/ installed 3 windows, an air conditioner and installed recessed lighting in the bathroom/installed interlocking vinyl flooring in the storage area, main room and stairs (repaired two broken stairs and lots of extras, e.g. installed a lighting fixture in the hallway by the stair landing, a make up/shaving mirror in the bathroom, installed window treatments and assembled a 70 inch TV storage cabinet). We have booked him for future projects. We highly recommend Domenick and his team."

"Tom and his crew of men were great! They repaired a gutted basement apartment that was water damaged. They provided top notch quality work and finished sooner than was agreed upon. Their work encompassed sheet rock, taping and sanding, spackle, painting, plumbing, installing vinyl flooring and wood moldings and they removed all debris. It was nice to have them able to do it all for me. We signed the work order and they were on the job the next morning. It was my pleasure dealing with Tom who did all he said that he was going to do! I thank him for his fast, quality work and very fair price and I would highly recommend him to everyone. Bill N."

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

FAQs for basement remodeling projects in Rockville Centre, 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.
