"I highly recommend Alpha Foundations. The first guy they sent out to evaluate the problem, Joseph Green, was extremely thorough and professional. He went above and beyond to make me happy. The two men who did the job, which was leveling two patios and filling in a gap between the house and the patios and repairing two substantial cracks, Cooper and Blake, did an amazing job. They were extremely thorough, making sure they addressed all issues and they did the job in a timely manner and cleaned up as if they were never there. I am 100 percent satisfied with all three men and I would highly recommend them and hire them again."

"After getting a few quotes from other places, I decided to go with J &H Stoneworks. Jamie was wonderful! He made my Dream kitchen come true! Jamie was personable, honest, and reasonably priced. At one point there was minor problem with a piece of the countertop and Jamie was very concerned and quickly fixed the problem. My countertops look wonderful and I’m happy with them. I will definitely be using him again in the near future for my bathrooms."

"Overall Dan was very professional, responsive and punctual. It is amazing when you have a vendor show up at the time promised! He was always at least 10 minutes before the promised time. Dan and Tony were able to complete the long lists of items within a few days. I appreciate all of your hard work and dedication. The guys even came to my place on a Sunday to put in a half day to meet my deadlines. Be sure to be clear when giving direction - we had a couple mistakes that had to be fixed along the way due to paint selection in the wrong areas within the property. Dan and Tony fixed the issues once addressed with no complaints. Dan went above and beyond to help me with issues that arose during the project (i.e. exchanging a damaged bathroom vanity and minor retro fitting to old plumbing). Thank you again Dan for everything! I will definitely recommend you to my friends and family in the South Florida area.

"There were two 1950 bathrooms that we wanted to completely renovate. We started with another contractor that was awful and was terminated. We knew it would be difficult to find a contractor that would finish the other contractors work and correct their mistakes. Fernando graciously took on the task and, lucky for us, found many mistakes. He handled the obstacles quickly and tirelessly without complaint. The two bathrooms came out beautiful with large format ceramic tiles. We were so impressed with his work that we continued with other projects in the house including interior and exterior repainting, carpentry, and general repair of some messy areas that we were leaving for another day. He was present to review the work of his crew almost every day and his crews were friendly, respectful, and cleaned up after their work. His proposals were fair but at the upper range of the proposals we received. (I have found looking for the lowest price can lead to disaster). His invoicing was timely and detailed. The only drawback is his workers are Brazilian and some only speak Portuguese. This may lead to lead to communication issues at times. Learned to use Google translator and it is was very helpful with English to Portuguese."

FAQs for basement remodeling projects in Key Biscayne, FL

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.
