"Remodeling our kitchen was an interesting experience and we were very happy with the result. Since first day Jess was very helpful and transparent with the information we needed and was always available for any question we might had. He and his team did everything to make the experience as smooth and efficient as possible. It only took 2 weeks to complete the remodeling and they were very professional and always on time with the schedule."

"It went very well! I was very happy! I had bought a dryer from Best Buy, and the guys that came to install it, installed it incorrectly, so it didn?t work. After trying very hard to get them to come back to fix it without success, I decided to call an electrician.

The electrician came and saw it right away and fixed it within minutes. The guy lived really far from where I live and when I told him what my situation was, he made time that day to come. He was super friendly, very nice guy and obviously knew his job. He wasn?t going to give up, because it wasn?t immediately obvious why the dryer didn?t work. He was quite amazing!"

Florida Lifetime was terrific. They are extremely knowledgeable, professional and punctual. Anything we wanted to know about windows they knew. They did a beautiful job. The windows are well installed and because of this the temperature in our home is constant now. The county building inspector came by and was actually impressed with the work done, that we gave him the company's number. I would absolutely use them again.

Basement Remodel FAQs, answered by experts

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.
