How Much Does Patio Door Installation Cost in Kendall?

Patio door installation in Kendall, FL typically runs between $1,200 and $5,800 installed, depending on door type, glass specification, and opening size. Most Kendall homeowners replacing a standard 6-foot sliding glass door with an impact-rated unit land somewhere between $2,100 and $3,600 all-in – labor, hardware, and disposal included. At Sightline Windows & Doors, the written price you see before any work starts is the price on the final invoice: same document, no revision.

Patio Door Installation Cost Breakdown (2026)

Patio door pricing in Kendall has two real variables: the door itself and the complexity of the opening. Below are the ranges we see regularly in this market, broken out by door category. Every figure includes standard installation labor, frame prep, weatherstripping, and haul-away of the old unit.

What Those Numbers Include

Every installed-cost range above assumes: removal of the existing door, basic frame inspection and prep, new weatherstripping and threshold, hardware set, a quality check against the measured survey Sightline completed before the job started, and a documented photo record when the job is done. They do not include permit fees (Miami-Dade County currently charges a base permit fee that varies by valuation – typically $150 to $350 for a single patio door), structural header modification if the rough opening needs to be widened, or stucco patching if the exterior frame seat has deteriorated.

Permit fees and stucco work are line-itemed separately on the Sightline written quote – Haven Clause 1 means every cost is named before any work begins, not discovered afterward.

Labor Cost Alone

In Kendall, installation labor for a patio door runs roughly $350 to $750 for a straightforward swap-out in an existing opening. That range climbs when the rough opening needs adjustment, when the exterior is stucco over CBS (concrete block), or when the original frame has water infiltration that has softened the substrate. We see compromised frames fairly often in older Kendall homes built in the 1980s along the Hammocks and Sunset areas, particularly on units that were never impact-upgraded and have been taking South Florida weather for 30-plus years.

What Affects Patio Door Installation Pricing in Kendall

Six factors move the number more than anything else in this market:

• Impact rating and Miami-Dade NOA compliance. Kendall falls within Miami-Dade County’s High-Velocity Hurricane Zone (HVHZ). Any patio door on an exterior opening must carry a Miami-Dade Notice of Acceptance (NOA) to pass inspection. Impact-rated units cost more than non-rated units – typically $400 to $900 more per door – but they are not optional on permitted work. Lines like PGT, CGI, and ECO Window Systems have deep HVHZ-certified inventories; that’s a material reason Sightline specifies from those lines in this market.
• Frame material. Aluminum frames dominate older Kendall construction and hold tolerances well in humid conditions, but they conduct heat. Vinyl frames carry lower U-factors (a measure of heat transfer through the frame) and are gaining ground on west-facing Kendall openings that take full afternoon sun off the Everglades. The vinyl premium over aluminum is usually $200 to $500 per door installed, and the SHGC (solar heat gain coefficient) reduction often justifies it on an FPL bill.
• Opening width and panel configuration. A standard 6-foot two-panel slider is the Kendall baseline. Every additional foot of glazed width adds glass cost, hardware weight, and sometimes structural work. Homes in Pinecrest and the southern Kendall estates that back up to the canal often have 10- to 12-foot openings; those jobs routinely push past $4,500.
• Existing frame condition. CBS construction handles humidity well, but the wood nailer framing inside the rough opening does not always hold up. Water infiltration around an unsealed old frame – common on Kendall homes where the original sliding door was never properly flashed – means substrate repair before the new unit goes in. We document this at the measured survey stage so it’s on the written scope before work starts, not an add-on surprise mid-job.
• Permit and inspection requirements. Miami-Dade County requires a permit for any exterior door replacement. That permit triggers an inspection, and the inspection requires the installed product’s NOA on site. Some Kendall homeowners have been quoted lower prices by contractors who planned to skip the permit; that approach leaves the homeowner with an uninspected opening, a potential insurance issue, and a real problem at resale. The permit fee is real and it belongs on the written quote.
• Product tier and manufacturer. A CWS or ECO Window Systems slider at the entry tier and a PGT WinGuard or CGI Series 9600 at the performance tier can differ by $600 to $1,400 on the same opening. The right specification depends on the opening’s exposure, the homeowner’s energy goals, and the HOA’s aesthetic requirements – not on what happens to be in a warehouse. Sightline draws from eight manufacturer lines specifically so the opening dictates the product, not the other way around.

Impact Glass in Kendall: Not Optional, Actually Beneficial

South Florida’s building code gets discussed as a cost driver, and it is – but impact glazing on a Kendall patio door does more than satisfy an inspector. A properly specified impact slider with a low SHGC rating meaningfully reduces solar heat gain through a large west- or south-facing glass opening. In Kendall’s climate, where afternoon temperatures push into the mid-90s and direct sun exposure on a rear lanai door can last five or six hours, that spec decision affects the FPL bill every month, not just on storm days.

PGT’s WinGuard aluminum sliders and CGI’s impact-rated series are the units we see most frequently on Kendall jobs. Both carry Miami-Dade NOA, both are rated for the wind loads required in this county, and both come in configurations that fit the 6-foot and 8-foot openings that dominate Kendall’s 1980s and 1990s-era single-family homes. ViewLux units work well on custom-width or specialty openings where the standard catalog sizes don’t match the rough opening without modification.

Patio Door Installation: What the Process Looks Like at Sightline

Understanding the process helps homeowners see why costs land where they do. A patio door isn’t a box-swap – it’s a weathered opening in a structural wall, and every step has a documentation trail under the Haven Standard.

Step 1: Measured Survey

A Sightline technician measures the rough opening, reads the existing frame condition, checks the sightline depth (the visible edge of the frame from inside the room), inspects the threshold and head track for water damage, and photographs the existing unit. The survey document stays with the homeowner. The written quote cannot differ from it – this is Haven Clause 1 in practice.

Step 2: Written Scope and Product Specification

The quote names the door line (e.g., PGT WinGuard 4000 Series, 72″ x 80″, impact-rated, bronze anodized), the labor scope, the permit fee, and any substrate work identified at the survey. Nothing is described as “approximately” or “to be determined on site.” If something can’t be priced until the old unit is out, that condition is named and bounded in the scope document.

Step 3: Permit Pull

Sightline pulls the Miami-Dade permit. The NOA for the specified product goes into the permit package. This protects the homeowner’s insurance coverage and ensures the installation appears in the property record – relevant at resale and for any future insurance adjustment after a storm event.

Step 4: Installation

Background-checked, uniformed technicians handle the removal and installation. The installer’s license number is on the job record before they arrive – Haven Clause 3, Verified Crews. For patio doors on CBS construction in Kendall, the typical installation day runs four to six hours for a standard opening, longer if stucco work or frame repair is needed.

Step 5: Photo Record and 365-Day Done Right Promise

When the job is finished, a documented photo record is created and attached to the job file. The 365-Day Done Right Promise is written into every Sightline job under the Haven Standard: if it’s not done right, we make it right – not as a verbal assurance, but as a written commitment stamped on every job.

How to Save on Patio Door Installation in Kendall

Prices in Kendall have real floors set by Miami-Dade code requirements and the cost of HVHZ-rated product. There’s no legal path to a $700 impact door installation on an exterior opening in this county. What there is: several ways to get better value without cutting corners.

• Get the scope right at the survey, not after demo. The most common cost overrun on patio door jobs is frame damage discovered after the old unit is removed. A careful pre-installation survey – the kind that photographs the existing threshold and inspects the substrate before anything is removed – catches those conditions early, when there’s still time to adjust scope and budget. Sightline’s measured survey is designed around this.
• Match the product to the opening’s actual exposure. An 8-foot folding door on a shaded, north-facing lanai doesn’t need the same SHGC specification as an 8-foot slider on a south-facing pool deck. Correct specification means you’re not paying for performance you don’t need – and not under-specifying into a product that fails its energy goals in Kendall’s sun.
• Combine door and window projects when possible. If you’re planning a window replacement in the same quarter, doing it alongside a patio door job usually reduces the mobilization cost across both projects. The measured survey, permit work, and crew scheduling have fixed components that spread over a larger scope.
• Bring us a written competitor quote for a free second opinion. If you have a written estimate from another contractor, Sightline will review it at no charge – not to undercut it line by line, but to verify that the product specified actually carries a Miami-Dade NOA, that the permit is included, and that the scope covers what you think it covers. Kendall homeowners regularly bring us quotes where the permit fee is absent or the specified unit isn’t HVHZ-approved.
• Ask about FPL and Miami-Dade rebate programs. Energy-efficient glazing upgrades in South Florida occasionally qualify for utility or county incentives. Sightline can identify whether the specified unit meets current program thresholds; the savings aren’t guaranteed and program availability changes, but it’s worth a ten-minute check before the permit is pulled.

Kendall-Specific Considerations Worth Knowing

Kendall isn’t a generic South Florida suburb from an installation standpoint. A few local factors consistently affect patio door jobs here:

CBS Construction and Stucco Finishes

The majority of Kendall’s single-family homes are CBS (concrete block and stucco) construction, which is structurally sound for impact door installation but means the exterior frame seat is set in stucco. When an old frame is removed, the stucco around the opening almost always needs patching, and sometimes the original installer left gaps that allowed water to wick behind the frame over the years. We see this pattern regularly on homes in the Hammocks, Westwood Lakes, and Three Lakes areas – particularly on doors that were installed before Kendall’s hurricane retrofit wave in the mid-2000s.

HOA Finish and Color Requirements

A significant share of Kendall’s residential communities are governed by HOAs with architectural review requirements. Door frame color, glass tint, and exterior finish choices may need pre-approval. Sightline documents the specified product’s color and finish in the written scope so the homeowner has the product data sheet for their HOA submission before the order is placed.

West-Facing Openings and Solar Load

Kendall sits at the western edge of Miami-Dade County, with the Everglades as the backdrop to the west. Homes in subdivisions like The Crossings, Kendale Lakes, and Hammocks West often have rear patio doors facing directly into the late-afternoon sun with no natural shading. On those openings, the SHGC specification matters significantly – a unit rated 0.22 SHGC will perform very differently from one rated 0.40 on a hot July afternoon. Sightline’s written scope names the SHGC and U-factor of every unit specified, not just the brand name.

Permit Processing Times

Miami-Dade County’s permit office processes residential door permits on a timeline that varies by submission backlog. As of 2026, straightforward residential patio door permits in Kendall are typically processing in two to four weeks via electronic submission. Sightline factors permit lead time into project scheduling at the outset – it’s part of the written scope, not a variable that surfaces later.

FAQs: Patio Door Installation Cost in Kendall

How much does it cost to install a patio door in Kendall, FL?

Patio door installation in Kendall runs $1,200 to $5,800 installed, with most standard impact-rated sliding door replacements landing between $2,100 and $3,600. That range includes labor, hardware, removal of the old unit, and weatherstripping. Permit fees ($150 to $350 for most residential openings in Miami-Dade) and any substrate or stucco repair are separate line items on the written quote. Call (786) 321-3319 for a free estimate on your specific opening – the written price you receive before work starts is the same number on the final invoice.

Is a permit required for patio door replacement in Kendall?

Yes. Any exterior door replacement in Kendall requires a Miami-Dade County permit, and the installed unit must carry a Miami-Dade Notice of Acceptance (NOA) for the HVHZ designation that covers this area. Skipping the permit leaves the homeowner with an uninspected opening that may not be recognized by their homeowner’s insurance carrier after a wind event, and it creates a disclosure problem at resale. Sightline pulls the permit as a standard part of every exterior door job – it’s in the written scope, not an optional add-on.

How long does patio door installation take in Kendall?

Installation of a standard 6-foot impact sliding door on an existing CBS opening in Kendall typically takes four to six hours on the day of install. French doors and multi-panel units run six to eight hours. Permit processing adds two to four weeks before the install date, and stucco repair (if needed) may extend the job by a partial day. The timeline is documented in the written scope before any work starts.

What’s the difference in cost between a sliding glass door and French doors in Kendall?

Impact-rated sliding glass doors run $2,100 to $3,600 installed for a standard 6-foot opening in Kendall. Impact-rated French doors on the same opening run $2,800 to $4,500 – the additional cost reflects heavier hardware, different rough-opening geometry (French doors require precise plumb tolerances that sliders are more forgiving of), and typically more complex weatherstripping. If the opening is currently configured for a slider and you’re converting to French doors, there may also be structural header work required.

Can I save money by buying the door myself and hiring Sightline to install it?

Generally, no – and for a specific reason. An impact-rated patio door for a Kendall exterior opening must carry a Miami-Dade NOA, and that NOA is tied to the product installed by a licensed contractor following the manufacturer’s approved installation method. When a homeowner-supplied product is installed, the warranty and the NOA-compliant installation documentation become complicated to establish correctly. Sightline draws from eight manufacturer lines specifically to find the right specification at the right price for each opening – the product and the installation travel together on purpose.
