Windows & Doors Cost Breakdown: The Kendall Homeowner's Reference for 2026

Windows & Doors Cost Breakdown: The Kendall Homeowner’s Reference for 2026

The average gap between the first verbal estimate and the final invoice for window replacement in South Florida is documented by the Miami-Dade Consumer Services Department, and it is not because contractors are dishonest. It is because verbal estimates are made before a measured survey identifies rough opening conditions. In Kendall, where the housing stock spans from 1960s ranch homes near Dadeland to 1990s Mediterranean Revival in The Hammocks, those conditions vary block by block. This guide breaks down what a window or door project actually costs in 2026, line by line, so you can compare quotes with the same document your contractor should be using.

Quick Answer

In Kendall, a complete window and door replacement in 2026 typically ranges from $8,500 for a partial impact upgrade on a 1,200-square-foot home to $42,000 for full-home impact-rated window and door replacement with rough opening remediation on a 2,800-square-foot property. The final number depends on four variables most quotes bundle together: the NOA-approved product, Miami-Dade permit and inspection fees, code-compliant HVHZ labor, and any rough opening remediation uncovered during measured survey.

Per-Opening Costs in the 2026 Kendall Market

We specify every opening by what the frame requires, not by what is in stock. These are the price ranges we are writing in Kendall in 2026, based on measured surveys completed in Pinecrest-adjacent neighborhoods, The Crossings, and west Kendall near Tamiami Airport. Prices include product, labor, and basic perimeter sealant. They do not include permit fees, rough opening remediation, or specialty finishes.

Impact Single-Hung Window

The workhorse of South Florida residential construction. Fixed upper sash, operable lower sash, laminated glass meeting Miami-Dade HVHZ requirements.

• Standard opening (24″ x 36″ to 36″ x 60″): $1,100 - $1,650 per opening
• Oversized opening (up to 48″ x 72″): $1,800 - $2,400 per opening
• High-rise or ladder-access premium: add 15-20%

In our experience, homes built between 1975 and 1995 in Kendall, particularly in the Kings Creek and Calusa areas, often have non-standard rough openings from original aluminum window installations. These are among the warning signs Kendall homeowners should watch for. The measured survey catches this. The quote does not change after.

Impact Casement Window

Hinged at the side, crank-operated, superior air infiltration ratings. Preferred for coastal exposure and second-story installations where cleaning access is limited.

• Standard opening (24″ x 36″ to 30″ x 54″): $1,350 - $1,950 per opening
• Oversized or architectural grade: $2,200 - $3,100 per opening

Sliding Glass Door (Impact-Rated)

The most common replacement request we see in Kendall’s 1980s and 1990s inventory. Two-panel and three-panel configurations, with laminated glass and reinforced interlocks.

• Two-panel (72″ x 80″): $2,800 - $4,200
• Three-panel (108″ x 80″): $4,500 - $6,800
• Four-panel multi-slide: $7,500 - $11,000

We installed a three-panel PGT WinGuard sliding system in a Calusa home last quarter. The measured survey found the original 1987 opening was out of square by 3/8 inch across the header. That remediation, priced in the original document, added $340. No change order. No surprise.

Impact Entry Door

Includes pre-hung unit with impact-rated slab, frame, laminated glass lite (if specified), and multi-point locking hardware.

• Standard single door (36″ x 80″): $2,400 - $3,600
• Double door (72″ x 80″): $4,200 - $6,500
• Custom height or width: $5,500 - $8,500

Non-Impact Energy-Efficient Window

For interior rooms, second-floor installations shielded by impact-rated exterior openings, or homes in specific Kendall micro-climates with reduced wind exposure. Must still meet Florida Building Code energy requirements.

• Single-hung, vinyl frame: $650 - $950 per opening
• Double-hung or casement: $850 - $1,350 per opening

Specialty and Geometric Windows

Trapezoids, circles, octagons, and custom shapes. These require template manufacturing and extended lead times.

• Standard geometric (up to 24 sq ft): $1,800 - $2,800
• Custom template or compound curve: $3,500 - $6,000+

Miami-Dade Permit and Inspection Fee Schedule

Permit costs are not optional, and they are not uniform. Miami-Dade County structures fees by project valuation, with specific surcharges for HVHZ (High Velocity Hurricane Zone) product approval verification. Here is the 2026 fee schedule for residential window and door replacement in Kendall, which falls under Miami-Dade County jurisdiction.

Base Permit Fees

Additional fees apply:

• Electrical permit (if powered operators or integrated alarm contacts): $65 - $125
• Plumbing permit (if door replacement affects drain pan or threshold drainage): $45 - $85
• Re-inspection fee (if first inspection fails): $125 per occurrence
• Express plan review (optional, 2-day turnaround): 150% of base plan review fee

For a typical Kendall home replacing 12-15 openings with impact-rated product, expect total permit and inspection fees between $485 and $875. We pull every permit required under Haven Clause 2 (Arrive on Schedule) and schedule inspections around your availability, not ours.

The Miami-Dade Building Code requires NOA (Notice of Acceptance) documentation for every impact-rated product installed in HVHZ areas. We maintain current NOA certificates for every line we carry: PGT, CGI, CWS, and ES Windows. The permit application includes these documents. If your contractor cannot produce them, the permit will not issue.

Rough Opening Remediation: What It Costs and When It Happens

This is where verbal estimates fail. A contractor standing in your driveway cannot see whether the original builder used pressure-treated sill plate, whether termite damage has compromised the jack studs, or whether the header is properly sized for the span. Only a measured survey, with the interior trim removed and the existing unit extracted, reveals these conditions.

We price remediation by linear foot of affected framing, with a minimum charge per opening. Here are the 2026 rates we are writing in Kendall:

• Sill plate replacement (pressure-treated, termite-resistant): $18 - $28 per linear foot
• Jack stud sistering or replacement: $22 - $35 per linear foot
• Header reinforcement or replacement: $45 - $75 per linear foot
• Sheathing repair (exposed after unit removal): $12 - $18 per square foot
• Stucco repair and match (typical 4-6 inch perimeter): $35 - $55 per linear foot
• Interior drywall repair and texture match: $25 - $40 per linear foot

Which Kendall homes are most likely to need remediation? In our measured surveys since 2012, we have documented the following patterns:

1. 1960s-1970s ranch homes near Dadeland and South Miami Heights: Original jalousie windows converted to single-hung in the 1980s, often with undersized headers and non-treated wood. Remediation rate in our records: approximately 40% of openings.
2. 1980s-1990s construction in The Hammocks, The Crossings, and Calusa: Aluminum frame windows with integral nailing fins that corroded at the sill. Remediation rate: approximately 25% of openings, concentrated on south and west elevations.
3. Post-2000 construction in Kendale Lakes and west Kendall: Generally better framing, but we still find improper flashing details at second-story installations. Remediation rate: approximately 15% of openings.

The key variable is not age alone. It is prior replacement history. A home with one generation of replacement windows, installed in the 2000s by a contractor who did not flash properly, often presents more remediation than original construction.

Our measured survey documents frame condition with photographs you receive. If remediation is likely, we price it in the original written quote. If we cannot determine likelihood without extraction, we quote a range with a not-to-exceed ceiling. Haven Clause 5 (No Surprises) means the final invoice does not exceed that ceiling without written change order and your signature.

Insurance Premium Credits for Impact-Rated Openings

Florida law requires insurers to offer premium discounts for windstorm mitigation features. The specific credit for impact-rated openings is calculated through the Uniform Mitigation Verification Inspection, commonly called a wind mitigation inspection. This is separate from your window and door installation, but the installation documentation makes the credit possible.

How the Credit Works

The inspector completes Form OIR-B1-1802, checking one of four categories for opening protection:

1. No opening protection: 0% credit
2. Non-impact rated with approved storm panels: partial credit, typically 5-10%
3. Impact-rated openings with NOA documentation: full opening protection credit, typically 15-25% of windstorm premium
4. Impact-rated openings with NOA documentation and secondary water resistance: maximum available credit

For a Kendall homeowner with a $3,500 annual windstorm premium, upgrading from Category 1 to Category 3 typically yields $525 - $875 in annual savings. Over a 10-year ownership period, that is $5,250 - $8,750, often offsetting 15-25% of the total installation cost.

Documentation Required

To claim the credit, you need:

• Product Approval Numbers from the Florida Product Approval system or Miami-Dade NOA numbers for each installed unit
• Installation permit and final inspection sign-off
• Photographic evidence of installed product (we provide this as standard under Haven Clause 4, Evidence on Every Job)
• Wind mitigation inspection by a licensed inspector (we can recommend qualified inspectors in Kendall, or your insurance agent typically maintains a list)

Important: The credit applies to the windstorm portion of your premium only, not the entire policy. And the inspector must verify that all openings are protected to qualify for the opening protection credit. A mix of impact-rated windows and non-rated doors, or vice versa, typically disqualifies you from this specific discount.

We provide a mitigation documentation packet with every completed installation: NOA numbers, permit copies, final inspection approval, and dated photographs of each installed unit. This is not an upsell. It is standard evidence.

How Quote Structure Affects Your Final Price

There are two fundamental ways to structure a window and door quote in Kendall. The difference matters more than most homeowners recognize until they are comparing documents.

Structure A: Product + Labor Priced Separately

The contractor quotes a per-unit product price and an hourly or per-opening labor rate. This is common among smaller operators and some retail-supply arrangements. The risk: labor hours are estimated, and if remediation is needed, the hourly rate extends. We have reviewed competitor quotes under our Free Second Opinion service where the labor component increased 40-60% between estimate and final invoice.

Typical presentation:

• 12 impact single-hung windows @ $890 = $10,680
• Labor @ $285 per opening = $3,420
• Estimated total: $14,100

Structure B: Measured Survey and Final Invoice as Same Document

This is Haven Clause 1. We measure every opening, photograph frame conditions, specify the exact product by NOA number, and write a single price that includes product, labor, basic remediation allowance, permit fees, and standard trim. The number on the document you sign is the number on the final invoice.

Typical presentation from our measured surveys:

• 12 impact single-hung windows, PGT WinGuard, specified by NOA number
• Measured survey with frame readings and sightline dimensions
• Labor, including extraction, installation, insulation, and trim
• Permit and inspection fees
• Remediation allowance: $0 - $850 (not-to-exceed)
• Written total: $16,400

The Structure B quote may appear higher initially. It is often lower in reality. The Miami-Dade Consumer Services Department data on estimate-to-invoice gaps is driven almost entirely by Structure A arrangements where remediation, extended labor, and permit surprises accumulate.

Our Free Second Opinion on Any Written Estimate will show you exactly where a competitor’s quote may gap. Bring us any written document. We will review it against our measured survey standards at no charge.

Product Tiers and Manufacturer Lines

We carry eight manufacturer lines, specified by what the opening requires, not by what is in stock. In Kendall’s climate, with salt air exposure, intense UV, and HVHZ wind loads, we most commonly specify from these four:

PGT (Performance Glass Technology)

Florida-manufactured, broadest NOA coverage in the state. WinGuard aluminum and vinyl lines are our default specification for standard residential openings in Kendall. Laminated glass, thermal break frames, and the most extensive third-party testing documentation. Price position: mid-premium.

CGI (CGI Windows & Doors)

Aluminum impact specialists with strong commercial and estate residential presence. Estate Series and Sentinel lines for oversized openings and custom architectural applications. Price position: premium.

CWS (Custom Window Systems)

Florida-based manufacturer with strong energy performance numbers. Aria and WindPact lines for homeowners prioritizing U-factor and SHGC ratings for cooling cost reduction. Price position: mid-range to mid-premium.

ES Windows

Aluminum and vinyl impact lines with competitive pricing for volume installations. Strong specification for multi-unit properties and homeowners managing to a fixed budget without sacrificing HVHZ compliance. Price position: accessible premium.

How We Specify

The measured survey includes:

• Frame material recommendation (aluminum, vinyl, or aluminum-clad wood) based on elevation exposure and maintenance preference
• Glazing specification (laminated impact, insulated laminated, or triple-pane where code permits) based on orientation and cooling load
• Hardware grade based on operation frequency and security requirements
• Finish specification based on UV exposure and HOA requirements, where applicable

We do not stock inventory. Every unit is manufactured to the measured survey. Lead times in 2026 range from 4-6 weeks for standard sizes to 10-12 weeks for custom geometric or specialty finishes.

Common Mistakes to Avoid

• Accepting a verbal estimate as binding. In Miami-Dade County, a verbal estimate has no legal standing. Only a written scope with permit numbers and product specifications is enforceable. We have reviewed cases where homeowners paid 40% more than the “estimate” with no recourse.
• Assuming all “impact-rated” claims are equal. Only products with current Miami-Dade NOA or Florida Product Approval are legal for HVHZ installation. Some contractors install non-HVHZ product in Kendall, planning to “make it work” with additional anchoring. This fails inspection and voids the installation warranty.
• Neglecting the rough opening inspection. A quote written without interior trim removal is a guess. In Kendall’s 1970s inventory, we find concealed termite damage in approximately 15% of measured surveys. Guessing does not protect you from the cost.
• Overlooking permit responsibility. Unpermitted work must be disclosed on sale and can trigger insurance coverage disputes. Miami-Dade enforcement has increased significantly since 2023. The permit is not a formality; it is the legal record of code-compliant installation.
• Comparing quotes with different product tiers. A $1,100 single-hung and a $1,650 single-hung are not the same product. Compare U-factor, SHGC, design pressure rating, and frame wall thickness before comparing price.
• Ignoring insurance documentation. The wind mitigation credit requires specific paperwork. If your contractor does not provide NOA numbers, permit copies, and installation photographs, you will pay full premium for years.
• Choosing speed over survey accuracy. A 30-minute “quote” cannot include a measured survey. Our surveys take 60-90 minutes for a typical Kendall home because we measure twice, photograph frame conditions, and document sightline dimensions. The quote that takes longer to write is usually the one that costs less in the end.

When to Call a Professional

Window and door replacement in HVHZ zones involves structural, waterproofing, and code compliance considerations that exceed typical homeowner capability. Specific scenarios where professional installation is not merely advisable but necessary:

• Any opening requiring impact-rated product, which must be installed to manufacturer specifications to maintain NOA compliance
• Second-story or ladder-access installations, where Florida worker’s compensation and liability coverage requirements apply
• Openings showing water intrusion, frame rot, or stucco cracking, indicating systemic flashing failure
• Homes built before 1992, where original construction may not meet current wind load requirements and engineered solutions are required

Window Installation in Kendall and Door Installation in Kendall both require the same measured survey discipline. Whether you are replacing one failed unit or upgrading every opening for insurance credit, the process begins with documentation, not demolition.
