Windows & Doors Cost Breakdown: The North Palm Beach Homeowner's Reference for 2026

Windows & Doors Cost Breakdown: The North Palm Beach Homeowner’s Reference for 2026

A $450-per-window quote and an $850-per-window quote for the same house in North Palm Beach frequently arrive at the same final invoice. The gap collapses once permit fees, impact-glass upgrades required by Palm Beach County code, and flashing labor “not in the original scope” are added as change orders. We’ve reviewed competitor quotes for North Palm Beach homeowners since 2012, and the pattern is consistent: the difference is rarely contractor greed. It’s a difference in what was written down before anyone signed. This guide names every line item and 2026 price range so you can read a quote the way we read it - as a scope of work, not a sales pitch. For more guides & resources, see our blog.

Quick Answer

Complete window and door replacement for a typical 2,000-square-foot North Palm Beach home runs $8,500-$22,000 in 2026, with impact-rated glass, permits, and labor included. Single-window replacement ranges from $650-$1,400 installed; sliding glass door replacement runs $2,800-$6,500. The final cost depends on frame material, glass rating, whether the rough opening needs modification, and whether the quote you received actually includes all four of those elements. Our Complete Guide to Windows & Doors in North Palm Beach covers each factor in depth.

Why Quotes for the Same House Vary by $3,000-$12,000

We see this every month in North Palm Beach. A homeowner shows us three quotes for fifteen windows. One reads $6,750. Another reads $12,600. A third lands at $9,800. All three contractors visited the same house. All three measured the same openings. The homeowner assumes the middle quote is “fair” and the low quote is “a deal.”

Here’s what we find when we read the scopes line by line.

The $6,750 quote lists “15 windows, installed” and nothing else. No permit. No disposal. No mention of impact rating. The glass spec is “single-pane replacement” - which Palm Beach County will not approve for a replacement permit in the HVHZ (High Velocity Hurricane Zone) that includes North Palm Beach. The homeowner will pay $150-$400 for the permit later, plus a change order for impact glass upgrade, plus another change order when the inspector fails the rough opening because the flashing wasn’t included.

The $12,600 quote includes impact-rated PGT or CGI units, permit filing, two inspections, rough-opening modification for three windows where the existing frames are out of square, and disposal of the old units. It also includes a measured survey document the homeowner keeps, with sightline readings and glazing specs written down.

The $9,800 quote includes impact glass and permits, but specifies vinyl frames in a house that currently has aluminum. The homeowner doesn’t learn until month fourteen that vinyl expands differently in South Florida’s humidity and direct sun, and the sashes are starting to bind.

We price by the Haven Standard, which means Sightline Windows & Doors North Palm Beach home quotes are the measured survey itself. The document you keep before work starts is the same document we invoice against. No change orders. No “we forgot to mention.” The variation you see between quotes is usually variation in what was written down, not variation in what the job actually requires.

Unit Costs by Window and Door Type

These are 2026 installed price ranges for North Palm Beach, including impact-rated glass, standard aluminum or vinyl frame, and basic flashing. They do not include permit fees, rough-opening modification, or disposal unless noted.

Removal and disposal of existing units: $45-$85 per window, $180-$320 per door. Rough-opening modification when the existing frame is out of square or rotted: $150-$400 per opening. These are not upsells. They are physical realities of a 1970s Florida home that has settled and been exposed to salt air for fifty years.

Why Impact-Rated Glass Is Not Optional in North Palm Beach

Palm Beach County sits in the HVHZ, the most restrictive wind-borne debris region in the Florida Building Code. See our detailed guide on Windows & Doors Permits, Codes & Inspections in FL: What You Need to Know. For replacement windows and doors, the code is clear: if you’re pulling a permit - and any legitimate replacement requires one - the new unit must be impact-rated or protected by an approved shutter system. Most North Palm Beach homeowners are not installing shutters on replacement windows. The impact rating is the practical requirement.

The unit premium for impact-rated glass over non-impact is 30-45% at the manufacturer level. On a standard single-hung window, that’s roughly $180-$320 per unit before installation. Here’s why that premium exists:

• Laminated glass construction: two lites of glass bonded to a .090-inch interlayer, tested to withstand a 9-pound 2×4 at 50 feet per second
• Reinforced frame profiles: thicker aluminum or vinyl extrusions to handle the higher design pressure ratings (DP-50 minimum for most North Palm Beach zones, DP-60 for waterfront properties)
• Third-party certification: every impact-rated unit carries a Miami-Dade County Notice of Acceptance or Florida Product Approval, with traceable documentation

We’ve had North Palm Beach homeowners ask us to quote “non-impact to save money.” We explain that we cannot file a permit for non-impact replacement glass in this county, and we will not install without a permit. Any contractor who offers to do so is either eating the permit cost themselves (unlikely), planning to skip the permit (illegal and discoverable on resale), or planning to change-order the impact upgrade after contract signing (common).

The 30-45% premium is not negotiable. It is codified. What is negotiable is whether your quote includes it upfront or hides it until week three of the project.

Frame Material: Upfront Price vs. 10-Year Cost in Salt Air

North Palm Beach’s salt air, high humidity, and direct sun exposure punish window frames differently. The material you choose affects not just the invoice but the maintenance cost at year five, year ten, and year fifteen. We specify frames by what the opening requires, not by what is in stock, drawing from our eight manufacturer lines including PGT, CGI, and ECO Window Systems.

Aluminum frames

Unit cost: lowest upfront, typically 10-15% below vinyl for equivalent impact rating. Aluminum is strong, thin-profiled, and handles large glass spans well. The trade is thermal conductivity and finish durability.

In North Palm Beach salt air, painted aluminum frames begin showing chalking and pitting at year seven to nine. Factory-baked enamel finishes hold longer than field-applied paint, but neither is permanent. Budget $800-$1,500 for professional repainting or powder-coating at the 10-year mark for a full-home installation. Anodized aluminum (darker tones, higher initial cost) extends this to year twelve to fifteen.

Vinyl frames

Unit cost: 10-15% above aluminum upfront. Vinyl does not corrode, chalk, or require repainting. The pigment is through-body, so scratches don’t show as bare metal.

The risk in South Florida is thermal expansion and UV degradation. Lower-grade vinyl formulations become brittle and yellow after prolonged sun exposure. We specify virgin PVC with titanium dioxide stabilizer, which our manufacturer partners guarantee against color shift for ten years. In our experience, quality vinyl in North Palm Beach performs without issue through year twelve to fifteen. The maintenance cost is near zero. The replacement cost, if you chose budget vinyl, begins at year ten.

Composite/fiberglass frames

Unit cost: 25-40% above aluminum. Therma-Tru and ViewLux offer fiberglass options in entry systems; full window lines in composite are less common in our market but available through specialty order.

Composite frames handle thermal expansion better than vinyl and corrosion better than aluminum. The 10-year maintenance cost is negligible. For a North Palm Beach homeowner planning to hold the property fifteen-plus years, the lifecycle cost often favors composite despite the higher initial price. We calculate this explicitly in our written quotes when a homeowner asks us to compare materials.

What “Labor Included” Actually Covers

The phrase “labor included” on a quote is nearly meaningless without crew size, hours, and scope specified. We’ve seen North Palm Beach homeowners receive quotes where “labor” meant one installer working six hours, and quotes where it meant a two-person crew working two days with a third specialist for the sliding door. The total labor dollars were similar. The outcomes were not.

Standard window replacement: one installer, half-day per two windows

A single-hung or casement replacement in a standard opening - no rot, no squareness issues, no stucco repair - takes one qualified installer roughly two hours per window including setup, removal, install, interior trim, and basic cleanup. For a six-window day, that’s a one-person crew from 7:30 AM to 3:00 PM with breaks. Cost embedded in the unit price: typically $180-$280 per window.

Large sliding glass door: two-person crew, full day

A 3-panel impact sliding door weighs 400-600 pounds. It requires two installers for safe handling, plus a third if the old door is being lowered from a second-story opening. The rough opening must be checked for level and square; shimming and structural attachment take time. Flashing integration with the existing weather barrier is critical - this is where water intrusion starts if rushed. Embedded labor: $680-$1,200 for the door, depending on access difficulty.

Rough-opening modification: additional half-day per opening

When we remove an old window and find rot in the sill, or when the existing opening is out of square by more than 3/8 inch, the frame must be rebuilt. This is not a change order at Sightline; it’s in the measured survey we perform before quoting. If your quote doesn’t mention rough-opening condition, the contractor hasn’t looked closely enough, or they’re planning to bill it later.

Crew size affects schedule and quality in specific ways:

1. Two-person crews complete large door installations without damage to the unit or the home. One-person crews on heavy doors rush the flashing to finish before dark.
2. Background-checked, uniformed technicians with license numbers on record - Haven Clause 3 - mean the person at your door is traceable. This matters less on day one, more on day three when a trim piece doesn’t fit and someone needs to return.
3. Documented photo record on every visit, included standard, means labor is verifiable. You see what was done, not just what was billed.

When you evaluate a quote, ask: how many people, for how many hours, doing exactly what? A written scope should answer this. Ours does.

Permits, Inspections, and Code Compliance Costs

Every window and door replacement in North Palm Beach requires a Palm Beach County building permit. The contractor pulls it, or the homeowner pulls it. If a contractor suggests you “save money” by skipping the permit, they are asking you to assume liability for code compliance, insurance coverage, and resale disclosure.

Permit fees in 2026:

• Window replacement permit (1-10 units): $150-$250
• Window replacement permit (11-20 units): $250-$400
• Door replacement permit (single): $80-$150
• Door replacement permit (multiple or sliding glass): $150-$250
• Plan review fee (if required for custom or structural modification): $75-$150

These fees go to Palm Beach County, not to the contractor. A quote that doesn’t list them is either absorbing them (rare), planning to add them later (common), or planning to skip the permit (illegal).

Inspection scheduling:

Most replacement projects require two inspections: rough inspection after old units are removed and new frames are set but before interior trim, and final inspection after completion. Palm Beach County’s inspection availability varies seasonally; January through April is peak demand. A contractor who hasn’t built inspection scheduling into the timeline is a contractor who hasn’t done this before, or who is hoping you won’t notice the delay.

We include permit filing, fee payment, and inspection scheduling in every Window Installation in North Palm Beach and Door Installation in North Palm Beach quote. The homeowner receives the permit number and can verify it online. This is not a courtesy. It is Haven Clause 1: Have it in writing, and Clause 5: No surprises.

How to Reverse-Engineer What’s Missing from a Quote

We offer a Free Second Opinion on Any Written Estimate for exactly this reason. But you can do preliminary detective work yourself. Take the total project price and work backward through these line items.

Step 1: Separate product from everything else

Multiply the number of windows by the unit cost range for that type from our table above. Multiply doors similarly. If the quote total is close to this product-only number, labor, permits, and disposal are either missing or buried.

Step 2: Check for permit language

Search the quote for “permit,” “Palm Beach County,” “inspection,” or “code compliance.” If none appear, add $150-$400 to your expected final cost, or expect illegal work.

Step 3: Verify impact rating documentation

Every impact-rated unit must carry a Miami-Dade NOA or Florida Product Approval number. The quote should reference this, or the product specification sheet should. If a salesperson says “it’s impact-rated” but the written quote says “single-pane replacement,” believe the paper. We’ve seen this exact discrepancy in North Palm Beach quotes.

Step 4: Look for measured survey documentation

Before any work starts, did someone measure every opening and give you a document with sightline readings, frame dimensions, and product specs? Or did they walk the perimeter, count windows, and email a price? The second method produces change orders. The first method produces the Haven Standard quote - the measurement and the price are the same document.

Step 5: Ask about post-installation documentation

Will you receive photos of the completed installation, flashing details, and any issues encountered? Or is the “warranty” a verbal promise? At Sightline, the documented photo record on every job is standard evidence, not an upsell. You use it for insurance, for resale, and for your own reference if a leak develops three years later.

Step 6: Test the change-order scenario

Ask the contractor: “If you find rot in the sill, what happens?” If the answer is “we’ll let you know and bill accordingly,” that’s a change-order business model. If the answer is “we inspected for that during our measured survey and included it or excluded it specifically,” that’s a fixed-scope model. We operate the second way. The written price before any work starts is the whole point of Haven Clause 1.

Common Mistakes to Avoid

• Comparing per-window prices without comparing scopes. A $450 window and an $850 window are rarely the same product with the same inclusions. Read the line items, not the headline.
• Assuming “impact-rated” means the same thing from every contractor. DP-50, DP-60, and “hurricane resistant” are different specifications. Ask for the design pressure rating in writing.
• Ignoring frame material maintenance in a salt-air environment. That aluminum frame quote looks cheaper until you price repainting at year eight. Calculate ten-year cost, not invoice cost.
• Accepting a quote with no permit line item. In North Palm Beach, this means either hidden fees or illegal work. Either way, you discover the problem at the worst possible moment.
• Not verifying that “labor” includes disposal. Fifteen old windows sitting in your driveway is a $300-$500 surprise if removal was “included” but disposal was not.
• Choosing a contractor who won’t put the price in writing before work starts. Verbal estimates are not estimates. They are opening offers. The Haven Standard requires the written price to be the measured survey itself.
• Overlooking crew verification. A background-checked, uniformed technician with a license number is not a luxury in a home security context. It is a basic accountability measure that Haven Clause 3 requires.

When to Call a Professional

Call a qualified window and door contractor when you see daylight around a frame, feel drafts you cannot source, find condensation between glass lites, or notice operation becoming stiff after storm season. In North Palm Beach’s climate, these symptoms accelerate. Salt air corrodes hardware. Humidity swells frames. A window that sticks in October may not open in an emergency by June.

Call before you need to call. A measured survey identifies problems before they become water damage or security failures. Window Replacement in North Palm Beach is not always urgent, but it is always easier to schedule and price accurately before the rainy season.

Frequently Asked Questions

The Bottom Line

Window and door replacement costs in North Palm Beach are knowable before you sign. The variation between quotes is not mystery or markup - it is scope. Impact-rated glass, permits, disposal, rough-opening condition, crew size, and documentation are either priced upfront or billed later. The homeowner who reads a quote as a scope of work, not a sales number, avoids the $3,000-$12,000 gap that separates a signed contract from a finished invoice.

Since 2012, we’ve completed 18,000+ installations under the Haven Standard. Every one began with a measured survey the customer keeps and ended with a documented photo record. The written price before any work starts is not our promotion. It is our founding principle. If you’re evaluating quotes and want a second opinion on any written estimate, we review them at no charge.
