"GREAT! They were on time, stayed on budget, and brought in professionals in every area: tile, plumbing and shower door installation. It was painless for me because they did all of the coordination of workers during times that were convenient for our family. I recommend LCS Master Construction without reservation!"

"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."

"<p>I bought a foreclosure and had a very short timeframe to fix it up to be livable.  My wife had died in the house I was in and when I explained this to Dan, he worked day and night for the next two weeks helping me rebuild essentially the whole house.  He did a lot of electrical, plumbing, new bathroom, took down walls, put up walls, added heat and A/C to new rooms, moved the air returns, helped with hanging new cabinets, new garage doors, textured walls, drywall, painting, replacing doors, patching, cleaning and painting pool, major tile work and more.  I would definitely use him again for any work we need.  He was very honest and up front with me and didn't try to nickel and dime me out of everything I had.  I'm forever thankful for the amount of work in such a short timeframe his team was able to accomplish.</p> <br />"

"Henry came out when scheduled for a look at the job first and gave us a quote immediately. We agreed and scheduled the job and again he was right on time with materials and workers to do the job. They cleaned up afterward and the whole job was handled professionally. Also,  a lot of contractors that we have worked with, always demand money up front which is something i don't agree with and Henry did not ask for any money until the work was completed. We hope that we have the opportunity to work with him again."

"I spoke with the office and they provided me an appointment within the same week. The gentleman that came out to give me an estimate was very knowledgeable and answered all the questions and concerns I had. The price of the project was very reasonable. It was so much more affordable than replacing my driveway. The crew was prompt, courteous and answered all the questions I had during the process. It was so amazing to watch! The process only took a few hours and I was able to park on my driveway as soon as they were done. I would highly recommend Poly Lift USA to my friends and neighbors!"

FAQs for basement remodeling projects in Key West, 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.
