"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

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.
