"Designing Home did an amazing job from start to finish on our bathroom remodel. At the beginning, they took our requirements and gave their experienced feedback to help us get our vision into a plan. The execution was then very methodical and precise. It didn’t feel like the project was being rushed just to move on to another client. The result is beautiful and exactly how we envisioned it. Thank you so much for your knowledge and great work!"

"I purchased the deal shortly after speaking with him and he responded very quickly. The work was scheduled to begin on May 27th. John contacted me on May 1st to tell me that he had fallen and injured his back and would be unable to complete the job."

"Cornerstone did not have the lowest estimate for the kitchen but they did have the best design ideas that incorporated what we wanted in our kitchen.  The first day of the job, the project manager came early, reviewed the plans and gave us his contact info in case of any questions or issues.  From the demolition to completion, they showed up when they said, did the work and cleaned up after themselves. All of the the guys working on the kitchen took great care and pride in their work.  They were very exacting in their standards and did an excellent job.  We love our new kitchen, it looks even better than we expected. <br />"

"Everything in which IGA did for my family and I was out of this world in which serious was unbelievably beautiful perfect and came out to be much more than I could have ever imagined nor expected as well dream of I was in tears is how beautiful of a job they did on my entire home I have pictures if you would like to see. I am willing to go to any extent to help IGA construction become to most known that is the least I can do for all they did for me at a very low price for work that If I went with another company or contractor I would have paid triple plus some and the out come would have never ever been what it is now as I meantioned most beautiful work and a dream come true to have a home that I never thought was possible all thanks to IGA construction Matt as well crew."

"Dwight from Cornerstone Construction is the REAL deal! I am probably one of the pickiest people when it comes to contractors. I have never liked a single one, but Dwight is absolutely wonderful. They have remodeled our entire kitchen (removed our whole old kitchen and replaced it with a brand new kitchen including appliances, exhaust, backsplash, etc) - it looks perfect, which I NEVER say. I have no conflict of interest....I am tired of contractors who don't do a good job so when I found Dwight, I was ecstatic. I have used his company for the build out of my medical office and always refer our friends and family to him."

"Harmon Homes was great and I highly recommend them. We redid a very dated shower in our guest bath. It went very smoothly from beginning to end. So pleased with the outcome. Workmanship is outstanding. Everyone was professional. We plan on a remodel of the master bath in the fall and will use them again. They worked hand in glove with Year Round Painting and that went extremely seamless. Both companies receive high marks."

FAQs for basement remodeling projects in Sanibel, 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.
