"Revive renovations did a wonderful job installing luxury vinyl flooring in my basement! Also, they reinstalled drywall at the half bottom of the basement walls due to water damage! After installing the drywall, they paint matched the existing paint with the upper part of the walls. The workers are very efficient and friendly! I will hire Revive renovations for future projects!"

"The job that Mario and his assistants did remodeling our guest bath was exceptional. The crew was prompt, professional, courteous, and highly skilled in the field of remodeling work. Our bathroom was gutted and completely replaced in just 4 1/2 days. Cleanup was done daily with care and Mario was always available to answer questions. We highly recommend this company for any remodeling or construction project!"

"The process was smooth and quick! Roger contacted me the same day I inquired, was at my house giving me a quote the next day, Sunday, and began work the following day. His estimated 3 day repair was done in 2, and the fact that he started on a holiday Monday meant I barely missed any use of my work from home office, which is one of the rooms he worked in. The repairs were done exactly as I’d hoped. I only wish I had done this earlier. I never expected the process to be so easy. Definitely use Nickel City Repair. You don’t have to live with eyesores you know you will never get to yourself."

"I had an excellent experience with SZ Home Construction?. They completed the chimney maintenance, cleaning, and painting professionally and at a very reasonable price. The work was finished on time, and the quality exceeded my expectations. What impressed me the most was their attention to detail and respect for cleanliness ? they cleaned the entire area thoroughly after finishing the job, leaving everything neat and organized. Their team was polite, calm, and very easy to deal with. They worked smoothly and quietly without creating unnecessary noise or disturbance, which made the whole experience comfortable and stress-free. I also appreciated their professional and legal payment process through bank checks, which added an extra level of trust and reliability. I highly recommend SZ Home Construction? to anyone looking for honest, professional, and high-quality home service work."

"I needed complete drywall replacement in my garage, ceiling and walls. I did not know Southside Builders prior to hiring them for this project. The owner, Neil Dylag, showed up for the initial evaluation when he said he would. He provided a timely estimate. We agreed to a start date and estimated completion date. This project started and finished as scheduled with no additional charges or change orders. His solutions to the couple of glitches we had were sound and better than my recommendations. I found Neil to be an extremely hard working and honest businessman. I'm satisfied with the job and recommend him to your project."

FAQs for basement remodeling projects in Tonawanda, 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.
