"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

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.
