"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."

"Victor and his team did an excellent job on our bathroom remodel. His crew was very respectful, polite, and hardworking. They showed up each day on time and victor was here every day to make sure all was going well. We are very pleased with the final bathroom and highly recommend VAP Contracting!"

"We live in Bronxville, where the expectation are high for quality of work done on houses. Bud, and team, did an amazing job with a pretty large job. It was a full basement remodel, down to the studs, and he was great to work with. Really appreciate his professionalism and quality. I would recommend him fully, even for jobs that are larger and require a high level of finish quality."

"We interviewed four companies for our project. Hilltop Remodeling wasn't the most expensive or the least expensive. Bill, the owner, is very personable and we liked him right off. He and his crew are very professional and completed the job in a timely manner. They removed a tub in our sons' bathroom. They expanded, built, plumbed, and tiled a new shower stall. Hilltop also re-grouted our tile and painted the bathroom and our son's bedroom. We are very happy with the results and would rehire Hilltop Remodeling again."

"Customer Service was by far above expectations. I felt my basement was as important to Pella as it was to me. Also, we were given great recommendations throughout the process. Quality of the work was very good. Only area for improvement was that the upfront estimate had a couple minor misses, and I would have liked the laminate planks to have been laid with 3-4 row repeating pattern rather than a 2 row; but I never made that expectation known upfront. Overall an excellent experience and I highly recommend!"

"The carpenter that did the job (Adam) was amazing. He had to expand the space for one window, narrow the space for another, and repair much cedar siding that had rotted away due to water damage. He also reshaped my patio door so it would close and lock more easily. He is a very talented carpenter and I have no qualms about highly recommending him."

FAQs for basement remodeling projects in Greenwich, CT

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.
