Sliding Glass & Patio Doors in Westchester - Free In-Home Measure, Written Price

Fast, Reliable Sliding Glass & Patio Doors Across Westchester

Sliding glass and patio door replacement in Westchester typically runs $2,800 to $7,500 for a standard 6-foot impact-rated unit installed, and most jobs are completed in a single visit once the door arrives from the manufacturer. If your existing slider is an original single-pane aluminum unit from a 1950s or 1960s CBS ranch, expect the rough opening to need re-framing before the new door goes in. That’s the reality of working in Westchester, and we plan for it on every quote. Call (561) 956-2754 for a free in-home measure and a written line-item estimate.

Why TruePane Windows & Doors Is Westchester’s Preferred Sliding Glass & Patio Doors Company

TruePane was founded in 2008 by Dale Kessler, a second-generation glazier who grew up in the trade. The rule on the whiteboard hasn’t changed since day one: if the pane is not true, the job is not done. That’s how we approach every sliding door in Westchester, whether it’s a straightforward replacement on a CBS ranch near Bird Road or a custom multi-slide unit on a larger property along Coral Way.

We’re an authorized installer for more than a dozen manufacturer lines, including PGT, CGI, and CWS. When we quote a door, you see manufacturer options side by side on paper, with both warranty layers registered in writing before our truck leaves your driveway. That’s The Keystone Standard, and it’s not a slogan. It’s the way Dale built the company.

Westchester homeowners call us because a live person answers the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a regional call center. You call, a person picks up, and we schedule the measure. Our technicians are background-checked, uniformed, and trained as journeymen, not subcontracted crews. We serve Westchester locally, with scheduling coordinated from our South Florida office.

Our Sliding Glass & Patio Doors Services in Westchester

Impact-Rated Sliding Glass Door Replacement

Westchester sits inside Miami-Dade’s High Velocity Hurricane Zone, which means every replacement door must carry a Miami-Dade Notice of Acceptance. We install PGT, CGI, and CWS units engineered for large-missile impact and pressure cycling. A typical 6-foot impact slider for a Westchester ranch runs $2,800 to $4,800 installed, depending on frame material and glass package.

Patio Door Repair and Track Restoration

Older aluminum sliders in Westchester corrode from the inside out. Constant humidity attacks the rollers and track, and thermal expansion cycling in the frame eventually binds the door. We repair or replace rollers, re-align panels, and restore smooth operation. If the frame itself has lost its seal and the glass is fogging, repair is often a short-term fix, and we’ll tell you that plainly.

Custom Rough Opening and Buck Framing

This is where Westchester differs from newer suburbs. Homes built between 1950 and 1975 have concrete block walls that shift over decades. A door opening that was square in 1962 is rarely square today. We re-frame jambs, install custom bucks, and set the new unit true. Skip this step and the new door binds, leaks, and voids the manufacturer warranty. We do it right on the first visit.

Jalousie Side-Lite Replacement

Many Westchester ranch homes have jalousie side-lites flanking the patio slider. Miami-Dade code specifically calls out jalousie windows as non-compliant for hurricane protection. When you pull a permit to replace the sliding door, the inspector may require those side-lites to go too. We identify this upfront and include it in the written quote so there are no surprises on inspection day.

Trusted Brands We Service in Westchester

We install and service sliding glass doors from PGT, CGI, and CWS, among a dozen manufacturer lines. PGT’s impact units are the most common choice for Westchester CBS homes because their flange frames and buck options fit mid-century block construction without excessive modification. CGI builds a heavier commercial-grade frame that performs well on larger openings facing open yards. CWS offers competitive pricing on standard 6-foot and 8-foot sliders. We keep common parts in local inventory so repairs aren’t waiting on a cross-country shipment.

Common Sliding Glass & Patio Doors Problems We See in Westchester Homes

• Fogged glass from humidity-driven seal failure. Original single-pane aluminum sliders lose their thermal seal after years of Westchester’s year-round moisture. The glass fogs between panes and can’t be cleaned. Replacement is the fix, and the new unit must be NOA-approved.
• Binding or sticking panels from shifting CBS walls. Concrete block homes settle. Over 50 or 60 years, the rough opening goes out of square. A drop-in replacement binds on the jamb. We re-frame and buck each opening before setting the door.
• Corroded rollers and tracks from constant humidity. Aluminum frames cycle through daily expansion and contraction from heat and moisture. Rollers seize, tracks pit, and the door gets harder to move each year. Regular maintenance slows it; replacement ends it.
• Jalousie side-lites that fail permit inspection. Leave them in place during a slider replacement and the permit can be denied. Westchester homeowners learn this at inspection. We tell you before you spend a dollar.

What Sliding Glass & Patio Doors Costs in Westchester

A typical impact-rated sliding glass door in Westchester runs $2,800 to $7,500 installed, with the final number driven by size, frame material, and glass package. Standard 6-foot units with aluminum frames and laminated impact glass sit at the lower end. Large 8-foot or 12-foot multi-slide units on bigger properties push toward $7,500 or more. Custom fabrication runs four to six weeks from order to install.

What moves the price in Westchester specifically:

• Opening count: More doors, lower per-unit labor because the crew is already on site with tools staged.
• Wind zone and floor height: Westchester is inland, but still HVHZ. Design pressures are calculated per opening and never exceed +/-100 PSF. Higher exposures mean higher-rated units.
• Frame material: Vinyl costs less up front. Aluminum costs more but handles thermal cycling better over decades in Miami-Dade humidity. We quote both on paper and let you decide.
• Rough opening condition: Older CBS homes almost always need re-framing or a custom buck. It adds labor but guarantees a true install.

Florida Pays You Back

Florida homeowners in Westchester can stack several incentive programs when replacing a sliding glass door with impact-rated glazing. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida also exempts impact-resistant windows and doors from sales tax. On the federal side, the 25C energy credit returns 30% of the product cost, up to $600 per year, on qualifying units. After installation, a wind-mitigation inspection ($75 to $150) can document the upgrade for your insurance carrier, and many homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of the policy. Programs and carriers set the final numbers, so we don’t promise a specific credit. We do provide the documentation your inspector and insurer need.

Why Westchester’s Inland Homes Need the Same Glazing as Oceanfront Ones

Westchester sits inland in Miami-Dade County, far from the salt spray that eats aluminum frames on Miami Beach or Key Biscayne. But the sliding glass doors here fail differently, and sometimes faster. Constant humidity and intense solar heat drive daily thermal expansion cycling in aluminum frames. The metal swells, the seal breaks down, moisture gets between the panes, and the glass fogs. Rollers corrode. Tracks pit. The door gets harder to move every summer. That’s the failure mode we see most on original single-pane sliders in Westchester’s CBS ranch homes.

And here’s the part most homeowners don’t expect: every replacement still has to meet the same Miami-Dade NOA standard as a door on the water. Westchester is in the High Velocity Hurricane Zone, the only jurisdiction in the United States that requires every replacement window and door to carry a Notice of Acceptance. Inland location doesn’t exempt you. The same large-missile impact and pressure-cycle test standards apply to a home off SW 8th Street as to a condo on Brickell.

We learned this lesson on a 1950s CBS ranch off SW 8th Street. The homeowner called about a corroded single-pane aluminum sliding door that hadn’t opened smoothly in years. Our crew pulled the old unit and found the rough opening had shifted over sixty years. We re-framed the jamb, installed a custom buck, and set a PGT impact-rated unit. Then the permit triggered the requirement to eliminate the adjacent jalousie windows, because Miami-Dade code specifically calls jalousies non-compliant for hurricane protection. We upgraded those too. The homeowner had budgeted for a door. The code required more. We’d flagged it before the first truck rolled, so there were no surprises on inspection day. That’s how we scope every Westchester job.

Impact Windows vs. Hurricane Shutters: What Actually Protects a Sliding Door

Shutters protect a sliding glass door only when someone is home to deploy them, and only after the panels are dragged out of storage, lifted into place, and bolted down. A storm at 2 a.m. with the family asleep doesn’t wait for that. Impact-rated sliding glass doors protect the opening permanently, with laminated glass that stands up to large-missile impact and pressure cycling without anyone touching a panel. For Westchester homeowners planning to stay in their homes for another twenty years, the impact door is the investment that removes the annual shutter ritual entirely. We don’t sell or install shutters. We install doors that don’t need them.
