"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"The work was done in a timely and professional manner. I had used the basic footprint of both rooms. And after the work was done, they looked completely different and so much better. The workers actually finished the work in a reasonable amount of time and even came back one more time to check and do any finishing touches. Spencer was very helpful in my decision making in design. I highly recommend this company."

"Marcio was the general contractor for our bathroom remodel, hardwood floor installation. and interior painting/plaster repairs for a house in Eastchester, NY. He did an excellent job. His attention to detail was exemplary, and his communication skills are excellent. I was out of the state for most of the remodeling, and he was always quick to update me on progress with photos and e mails. He made smart suggestions about economical ways to deal with issues which arose during the remodel. I was so pleased with his work that I have used him for other smaller jobs."

"Victor and his crew were great. On time, unobstructive and Victor is a straight shooter. After using so many contractors that over explain things in an attempt to confuse, Victor was a breath of fresh air."

"Dominick did an excellent job on my project, which was to scrape our bathroom ceiling, do some light replastering, and prime and paint with a special anti-mold paint. He and his assistant arrived on time both days, took great care to protect our floors and bathroom, and even vacuumed our ceiling vent for us. His prices are on the high side, but we're thrilled with the result and would work with him again."

"Very professional and polite. Came on a Sunday stayed late to try and finish it all in one day. Quality of the work was excellent. They took their time and made sure all ceiling fans and light fixtures were in stalled properly and functioning correctly. Returned a day later and installed 2 new toilets. Highly recommend them."

FAQs for basement remodeling projects in Mamaroneck, 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.
