Fast, Reliable Impact Windows & Doors Across Big Pine Key
Impact windows and doors in Big Pine Key are not an upgrade. They are a building-code requirement, a storm-survival system, and a salt-air endurance test all in one.

TruePane Windows & Doors installs and services Custom Windows & Doors in Big Pine Key, including NOA-rated impact windows, sliding glass doors, entry doors, and more across the island, from Key Deer Boulevard down to the waterfront lots off Long Beach Drive and along Wilson Key Lane.

Why Big Pine Key Homeowners Call TruePane for Impact Windows & Doors
We are a second-generation glazier company. Dale Kessler founded TruePane in 2008 on a rule that still sits on the whiteboard: if the pane is not true, the job is not done. Around Big Pine Key, that rule gets tested harder than almost anywhere else in Florida. Salt spray off the Atlantic and Florida Bay works on window hardware like sandpaper. Code enforcement under Monroe County’s HVHZ mandate is strict, and for good reason. Homeowners here have been burned once already, by storms and by contractors who cut corners during the rebuild. We get that. We price the work honestly, register both warranty layers in writing before the truck leaves the driveway, and stand behind every install with our Done Right Promise. No paperwork fights. No arguing. If it is not done right, we make it right.
Our crews work in Big Pine Key regularly. Background-checked, uniformed technicians measure every opening twice before ordering, because an eighth-inch error on a stilt home’s racked frame can crack a new impact unit. We quote manufacturer lines side by side on paper so you see exactly what you are buying, from CGI laminated glass to ES Windows fusion-welded frames and CWS impact-rated sliding doors. Serving Big Pine Key means understanding that the correct window here is not always the same window a mainland house would get. We specify marine-grade stainless hardware as standard. Most window companies in South Florida do not.
Our Impact Windows & Doors Services in Big Pine Key
Hurricane Impact Windows
Every impact window we install in Big Pine Key carries a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval. That is not optional. Monroe County’s High Velocity Hurricane Zone designation means a mainland-spec window from a big-box store will fail permitting before it ever leaves the shelf. We install single-hung, double-hung, casement, fixed, and custom-shaped impact windows sized to your rough openings. On older Big Pine Key homes, we often pull a 1950s or 60s jalousie unit and find the opening was never flashed properly. We fix the opening before we set the window, and we document everything in writing before we touch it. Typical impact window replacement in Big Pine Key runs $900-$2,100 per opening, installed, depending on size, frame condition, and glass package.

Impact Sliding Glass Doors
Salt-laden wind off the open water is hard on sliding door tracks. We regularly replace Big Pine Key Sliding & Patio Doors where the original rollers have seized and the panel grinds instead of glides. We install impact-rated sliders from CGI, ES Windows, and ECO Window Systems with stainless steel roller assemblies and reinforced interlocking stiles. A typical impact slider in Big Pine Key runs $3,800-$7,500, depending on width, glass type, and whether the existing rough opening needs reframing. That reframing is common here. Pre-Irma framing was often undersized for the weight of a laminated glass panel.

Impact Entry & French Doors
In Big Pine Key, an entry door does more than welcome guests. It is the first line against wind-driven rain coming horizontally off the water. We install impact-rated entry doors and French doors with compression-molded fiberglass or extruded aluminum slabs, multi-point locking hardware, and full-perimeter weatherstripping. If your existing door binds in July and lets daylight through the threshold, the problem is usually a twisted jamb or rotted sill sitting on salt-soaked framing. We fix the opening, not just the door. Impact entry door installation in Big Pine Key typically runs $2,600-$5,400. French door sets run $4,800-$9,200 depending on configuration and opening condition.

Impact Garage Doors
Big Pine Key garages take a beating. The wind loads on an exposed garage door are enormous, and many post-Irma rebuilds used the cheapest code-compliant door available, which often means the cheapest hardware. We brace and replace impact-rated garage doors with reinforced tracks, hurricane-rated hinges, and corrosion-resistant springs. If your garage door groans when the wind pushes against it from the bay side, that is a wind-load problem, not a lubrication problem. Impact garage door replacement in Big Pine Key runs $2,900-$6,800 installed, depending on door size, insulation, and whether the tracks need replacement.

Trusted Brands We Service and Install in Big Pine Key
TruePane is an authorized installer for more than a dozen manufacturer lines, and in Big Pine Key we recommend specific units because they survive this environment. We install and service CGI impact windows and doors, as well as Big Pine Key Glass Railing Systems, among the most common NOA-rated products specified in Monroe County rebuilds. We also work with CWS for their hurricane-rated sliders, ES Windows for fusion-welded aluminum frames that resist salt creep, and ECO Window Systems for a strong mid-range line. Because we install these lines heavily across the Lower Keys, we can source replacement hardware, rollers, and sash components quickly when a Big Pine Key customer calls about a binding slider or a fogged insulated unit. We quote these brands side by side on paper. You decide with numbers in front of you, not a sales pitch.
Common Impact Windows & Doors Problems We See in Big Pine Key Homes
- Corroded hardware on recently installed impact units. The salt spray off Big Pine Key’s open water is relentless. Mainland-spec locks, hinges, and rollers oxidize and fail in three to five years. We replace them with marine-grade stainless components that are actually specified for a saltwater environment.
- Rot hidden behind old jalousie frames. Jalousie windows were never flashed properly in most 50s-to-70s era Keys homes. Wind-driven rain sat against the rough opening for decades. We find rotted sheathing, rotted studs, and failed waterproofing whenever we pull one. Any permit-triggered renovation that touches that opening mandates an NOA-rated impact replacement, so the rot has to be addressed then, not later.
- Deflecting or cracked frames under the weight of new impact glass. NOA-rated laminated glass is heavy. Pre-Irma framing in Big Pine Key was sometimes undersized for the load. When the old sash comes out, the rough opening flexes. We sister studs, add king studs where needed, and shore the opening before the new unit goes in.
- Binding doors that worked fine until summer. Big Pine Key swells and shrinks with the seasons. Wood framing shifts with humidity. A door that opens easily in February binds in July. We plane, shim, and reset the jamb to level and plumb, then seal it so the next July does not undo the work.

FAQs - Impact Windows & Doors in Big Pine Key
Jalousie windows cannot be made impact-compliant under Monroe County code. If your renovation touches a jalousie opening, even replacing a sill or repairing the stucco around it, the permit triggers a mandatory upgrade to an NOA-rated impact unit. That converts a small patch job into a full replacement. We handle that transition every week in Big Pine Key. We remove the jalousie frame, repair the rough opening (which almost always has hidden rot), and install a code-compliant impact window that meets HVHZ requirements. Budget for the full replacement when you plan a remodel that touches any jalousie opening. Call (954) 280-4413 and we will walk through what your specific project triggers.
Yes. Monroe County requires a permit for any window or door replacement on a residential structure in Big Pine Key, including work on post-2017 rebuilds. The permit confirms the new unit carries a Miami-Dade NOA or Florida Product Approval, and it creates a record that your home meets current HVHZ requirements. We pull permits on every job, including impact window, sliding door, entry door, and garage door replacements. No exceptions. Call (954) 280-4413 and we will explain the permit path for your specific property.
Because they were installed with mainland-spec hardware. Big Pine Key sits in some of the most aggressive salt-spray air in the continental U.S. Standard zinc-plated locks, hinges, and rollers oxidize and seize within three to five years. The fix is replacing that hardware with marine-grade stainless components designed for a saltwater environment. When we install new impact windows and doors in Big Pine Key, we specify stainless hardware as standard, and we write it into the contract so you can verify it. If your existing locks are already bound, call (954) 280-4413. Hardware replacement is often a single-visit fix.
You want three things in writing. First, an allowance line for framing and waterproofing repair, because on a stilt home with pre-Irma framing, hidden rot under old openings is more likely than not. Second, explicit confirmation that every unit carries a Miami-Dade NOA or Florida Product Approval for the exact model and size being installed. Third, both warranty layers registered in writing: the manufacturer’s glass and frame warranty, and the installer’s workmanship warranty, with durations stated. TruePane writes all three into every Big Pine Key contract. The Keystone Standard is our baseline, not an upsell. Call (954) 280-4413 and we will show you exactly what a complete contract looks like.
You can, but only if the specific model carries a Miami-Dade NOA or Florida Product Approval. Many mainland ENERGY STAR double-hung windows do not meet HVHZ requirements and will not pass permit review in Big Pine Key. Even among approved models, the frame matters. In this salt air, extruded aluminum or vinyl frames hold up better than wood or wood-clad options, which take on moisture and corrode at the hardware mounting points. We recommend specific NOA-rated double-hung units from CGI, ES Windows, and ECO Window Systems for Big Pine Key’s climate. Call (954) 280-4413 for a side-by-side quote on your openings.
