"If you're looking to remodel, hire Bud at Above & Beyond Contracting! Him and his crew were reliable, trustworthy, friendly and easy to work with. His quote was by far the most detailed & fair I received. If there was an issue, he put your mind at ease and took care of it. He recommended details I didn't even think of and it elevated the remodel & I love it. I am so happy with my renovation and couldn't be happier that I went with Above & Beyond Contracting."

"We had our kitchen completely remodeled by Hire Her Home Improvement. Angela and her crew were very professional and responsive throughout the whole process. They were punctual, efficient, and always left the house clean when they left for the day. They were very respectful of our home. The job was completed on time and the kitchen came out beautiful! Angela was always available to answer any questions and always kept us updated. She is very knowledgeable, patient, and a pleasure to talk to. All the costs were clearly communicated and there were no surprises. I would highly recommend Hire Her for any home remodel or repair!"

"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."

"Nixon was amazing. I never have good experiences with handymen but he was able to fix my front door, weatherproof my doors, and fix my dehumidifier basement issue that have been huge issues before now. He’s reliable and does a great job. Highly recommend!"

FAQs for basement remodeling projects in Katonah, 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.
