Lanai Wondow & Door in Port St Lucie

Impact Window & Door Replacement for Lanais and Patios in Port St. Lucie, FL

Many homes in Port St. Lucie were built with screened lanais and patio enclosures designed for airflow, not year-round use or storm protection. Over time, screens stretch, frames loosen, and old patio doors become weak points during hurricane season. Replacing those systems with impact-rated windows and doors turns an exposed space into a functional extension of your home.

Liberty Impact Window & Doors specializes in upgrading existing patios and lanais with custom impact window and door systems. This is not new construction. We work with what you already have and replace outdated screens, windows, or doors with solutions designed for Florida’s wind, rain, and heat.

Replacing Screen Enclosures With Impact Windows

Screen enclosures were never intended to handle storm pressure, water intrusion, or temperature control. Replacing screens with impact windows requires more than simply swapping materials. The framing, anchoring, and load paths all matter.

Our team evaluates the existing enclosure structure, determines what can be reinforced or reused, and installs impact-resistant patio enclosure windows that meet Florida Product Approval requirements. The result is a sealed, secure enclosure that resists wind-driven rain, reduces heat gain, and eliminates the constant maintenance that screens require.

This type of work is routine for us. We replace screen enclosures with windows across coastal and inland Florida homes every week.

Custom Impact Windows for Patio and Lanai Enclosures

Not all patios are built the same. Some wrap around pools, others connect directly to interior living areas, and many older lanais were designed long before impact standards existed.

We install custom lanai enclosure windows sized and configured specifically for your space. Horizontal roller windows, fixed impact panels, and sliding glass systems are selected based on airflow needs, usage patterns, and exposure to wind. Every installation balances performance with how the space is actually used.

Port St. Lucie homes near the St. Lucie River and along open canal systems often experience higher wind exposure during storms. That local reality is built into how we design and install each enclosure upgrade.

Replacing a Patio Door With a Window

In some enclosures, an old patio door no longer makes sense. Homeowners often want better wall space, improved insulation, or a cleaner layout.

Replacing a patio door with a window involves removing the door system, modifying the opening, reinforcing the framing, and installing an impact-rated window designed for that specific span. This is structural work, not cosmetic work.

We handle the entire process, from assessing the enclosure’s load requirements to installing the new window system so it integrates cleanly with the surrounding enclosure. When done correctly, the space feels intentional, not patched.

Patio Door and Window Replacement That Holds Up in Florida

Older patio doors and windows are common failure points during storms. Weak locks, thin glass, and outdated tracks compromise both security and energy efficiency.

Our patio window and door replacement services focus on impact-rated products built for Florida conditions. These systems resist pressure changes, reduce outside noise, and help stabilize interior temperatures inside enclosed patios and lanais.

Every product we install is chosen for performance first. We do not retrofit shortcuts into structures that need real reinforcement.
