AfterHow Much Does Patio Door Installation Cost in West Palm Beach?
Patio door installation in West Palm Beach typically runs between $1,200 and $6,800 installed, depending on door type, glass specification, and whether the rough opening needs modification. Most West Palm Beach homeowners replacing a standard sliding glass door with an impact-rated unit land somewhere between $2,400 and $4,200 all-in. That number shifts when you add a multi-panel configuration, a non-standard sill height, or a product that requires Miami-Dade Notice of Acceptance (NOA) documentation for permit approval.
At Sightline Windows & Doors, every price you see here reflects what we actually quote on jobs in West Palm Beach – from Flamingo Park bungalows with original aluminum frames to newer construction in Ibis and Ibis Golf & Country Club where the rough openings are clean but the HOA has finish requirements. The written price you receive before any work starts is the same number that appears on the final invoice. That is Haven Clause 1, and it is not negotiable on our end.
Patio Door Installation Cost Breakdown (2026)
Patio door installation in West Palm Beach costs what it costs for three reasons: the door itself, the labor to set it correctly, and the permit and inspection cycle that Palm Beach County requires for any structural opening. Below is how those pieces stack up across the configurations we install most often.
| Door Type / Configuration | Product Range | Installed Price Range (West Palm Beach, 2026) |
|---|---|---|
| Standard aluminum sliding glass door (non-impact), 6 ft. | ES Windows, ECO Window Systems | $1,200 – $2,100 |
| Impact-rated sliding glass door, 6 ft. (SGD) | PGT, CGI, CWS | $2,400 – $3,800 |
| Impact-rated sliding glass door, 8 ft. | PGT WinGuard, CGI Guardian | $3,200 – $4,800 |
| Impact-rated French door (double), 6 ft. | Therma-Tru, PGT | $3,000 – $5,200 |
| Multi-panel folding/stacking door (3-4 panels) | CWS, ViewLux | $5,800 – $11,500+ |
| Non-impact energy-efficient sliding door with Low-E glazing | ES Windows, ECO Window Systems | $1,600 – $2,800 |
| Frame modification / rough opening adjustment (add-on) | Labor only | $300 – $900 |
| Palm Beach County permit and inspection | County fee, pass-through | $120 – $350 |
| Stucco or drywall repair after frame removal | Sub-trade or Sightline crew | $200 – $600 |
| Screen door addition or replacement | Coordinate with door manufacturer | $180 – $480 |
A few things worth understanding about these numbers. The impact-rated tier is not optional for most West Palm Beach homes – Palm Beach County’s wind-load ordinance, updated in line with the Florida Building Code 8th Edition, requires impact-rated or protected glazing on any opening in the county’s wind-borne debris region, which covers the entire incorporated city. If you see a quote for a non-impact door without a corresponding storm shutter credit, ask the contractor how they are addressing code compliance. We will explain it on the written scope before any tool touches the frame.
The multi-panel folding door category starts at $5,800 installed for a basic three-panel unit and can exceed $15,000 for a flush-sill, thermally broken configuration from CWS or ViewLux with a custom width. Those jobs also require a structural engineer’s letter in some Palm Beach County jurisdictions, which runs $400 to $800 separately. We handle the coordination; you keep the documentation.
What Affects Patio Door Installation Pricing in West Palm Beach
No two West Palm Beach openings are identical. Here are the six variables that move the number most.
- Impact rating and NOA documentation. Every door installed in West Palm Beach needs to carry a Miami-Dade Notice of Acceptance or a Florida Product Approval number to pass Palm Beach County inspection. Impact-rated units from PGT, CGI, and CWS come with this documentation as standard. Non-impact doors require a verified storm protection solution for the opening – factor that cost in before comparing quotes.
- Door width and panel count. A 6 ft. two-panel slider and an 8 ft. three-panel slider are structurally different installations. The wider the opening, the heavier the header load, and in older West Palm Beach neighborhoods like El Cid or Northwood, that header often needs assessment before the door order is placed. We measure it during the survey; it is not a surprise on the invoice.
- Frame material and thermal performance. Aluminum frames are standard in West Palm Beach and handle the humidity without warping. Thermally broken aluminum – where a non-conductive barrier separates interior and exterior frame sections – adds cost but meaningfully improves U-factor performance. In a home where the A/C runs eight to nine months a year, the energy math often justifies the upgrade. Vinyl frames are available but less common in South Florida’s UV environment; we will tell you which products hold up and which ones we have seen degrade.
- Glass specification: Low-E coating and SHGC. Solar Heat Gain Coefficient (SHGC) is a number between 0 and 1 that tells you how much solar radiation the glass lets through. In West Palm Beach, a lower SHGC – typically 0.23 to 0.27 on the products we specify – reduces cooling load. Glass with a low SHGC and a Low-E coating costs more than standard clear glass, but Florida’s energy code (FSEC compliance) may require it depending on the home’s orientation. The product spec sheet on every door we quote names the exact SHGC.
- Existing frame condition and rough opening work. Homes built before 1990 in West Palm Beach often have aluminum frames that are corroded at the sill or have water infiltration damage behind the stucco. We find this on the measured survey, not after the old door is out. When a rough opening needs concrete or masonry work, that is a sub-trade cost that gets added to the written scope – not called in on the day of install.
- HOA finish requirements. West Palm Beach communities including Palm Beach Lakes, Ibis, and Baywinds have HOA architectural review processes that specify frame color, exterior hardware finish, and sometimes glass tint. An HOA rejection means a re-order. We ask for the HOA spec sheet at the survey stage so the product choice matches before anything is ordered. This costs no extra but saves three to six weeks.

AfterImpact vs. Non-Impact Patio Doors in West Palm Beach: What the Price Difference Buys You
The installed price gap between a non-impact sliding door and an impact-rated equivalent runs about $800 to $1,400 on a standard 6 ft. opening in West Palm Beach. That gap closes when you account for what the non-impact door requires to be code-compliant: either accordion shutters ($600 to $1,200 for a patio opening) or a Bahama shutter system that affects daily use of the space.
Impact-rated patio doors from PGT’s WinGuard line and CGI’s Guardian series use laminated glass – two panes of tempered glass with an interlayer that holds the glass together if it breaks under impact. The interlayer is what earns the product its Large Missile Impact rating under ASTM E1886 and ASTM E1996. That rating is what satisfies the Palm Beach County building department without any additional shutter system. Most of our customers in West Palm Beach who do the math on shutter cost plus shutter maintenance plus the inconvenience of deploying shutters before every named storm choose the impact door.
There is also an insurance credit to consider. Many Florida homeowners’ policies offer a premium reduction for openings protected by approved impact glazing. The exact credit varies by carrier and policy, but it is worth a call to your agent before you finalize the product tier. We can provide the product’s Florida Product Approval number so your agent has what they need to run the calculation.
Sliding Glass Door vs. French Door vs. Folding Door: Cost and Fit for West Palm Beach Homes
Sliding Glass Doors (SGD)
The most common patio door in West Palm Beach. One panel slides behind the other on a track, which means the full opening width is never fully clear – you get approximately half the width as clear passage. Installed cost on an impact-rated 6 ft. PGT or CGI unit runs $2,400 to $3,800. The track at the sill is the one maintenance point; in West Palm Beach’s salt-air environment, stainless hardware and a marine-grade track system matter. We specify those details on the product sheet.
French Doors (Hinged, Double Panel)
French doors swing open, giving you full clear width. The trade-off is that both panels need swing clearance – typically 36 inches of floor space on the interior. In tighter West Palm Beach floor plans, that matters. Impact-rated Therma-Tru and PGT French doors land between $3,000 and $5,200 installed. The hinges and multi-point locking hardware are the components we check most carefully on the measured survey, because a door that is not plumb on install will drag within two hurricane seasons.
Multi-Panel Folding / Pocket Doors
Three to six panels that fold and stack against one or both jambs, opening the full wall. These are architecturally dramatic and they work well in West Palm Beach indoor-outdoor spaces where the pool deck or covered lanai extends the living area. The installed cost starts at $5,800 for a basic three-panel unit and climbs steeply with panel count, flush-sill requirements, and custom widths. The structural header assessment is non-negotiable on these jobs. We coordinate the engineer’s letter; it becomes part of the documented job record.
Palm Beach County Permit Requirements for Patio Door Installation
Palm Beach County requires a building permit for any patio door replacement or new installation. The permit application requires the product’s Florida Product Approval (FPA) number or Miami-Dade NOA, a signed and sealed installation drawing for some configurations, and a licensed contractor of record – which is Sightline on every job we touch.
The permit fee itself runs $120 to $350 depending on the declared value of the installation. Inspection is scheduled through the county’s online portal; the inspection window in West Palm Beach currently runs four to seven business days from permit issuance during normal volume periods. We have seen that stretch to ten to fourteen days during post-storm permit surges – worth knowing if you are planning around a timeline.
Working without a permit on a patio door in West Palm Beach creates problems at resale. A 4-point inspection – standard for any Florida home sale where the house is more than ten years old – will flag an unpermitted opening. The cost to retroactively permit and potentially re-install a non-compliant door is nearly always higher than pulling the permit correctly the first time. We include permit coordination in every installation scope; it is not an optional add-on.
How to Save on Patio Door Installation in West Palm Beach
There are real ways to reduce the total cost of a patio door installation in West Palm Beach, and there are false economies that create problems later. Here is the difference.
- Get the written scope before you compare quotes. A quote for a $1,800 installed door and a quote for a $3,600 installed door are not comparable unless both name the same product, the same glass specification, the same permit inclusion, and the same warranty terms in writing. Bring us any competitor’s written estimate and we will review it at no charge – that is our Free Second Opinion offer, with no obligation attached.
- Combine openings when possible. If you have two patio doors to replace – say, the main living room slider and a secondary bedroom door – scheduling them on the same visit reduces mobilization cost. On multi-opening jobs in West Palm Beach, we typically save $200 to $400 versus two separate visits, and that savings gets passed to the written price.
- Choose the right product tier for the opening, not the most expensive one. A secondary bedroom door that faces a covered lanai may not need the same impact specification as a main living room door facing west. We specify by what the opening requires. If a less costly unit satisfies code and performs correctly for that location, that is what goes on the quote.
- Check your homeowners’ insurance before ordering. Florida carriers with wind mitigation credits sometimes have preferred product lists. If your insurer offers a meaningful premium reduction for a specific impact-rated product we carry – PGT, CGI, and CWS are the most commonly credited lines in Palm Beach County – that credit can offset a meaningful portion of the product upgrade cost over three to five years.
- Avoid the permit-skip trap. Some installers quote lower by omitting the permit. In West Palm Beach, that saves $120 to $350 upfront and creates a potential five-figure problem at the next 4-point inspection or insurance claim. The permit is in the written scope on every Sightline job because it is not optional under the Haven Standard.
- Ask about the 365-Day Done Right Promise before signing anything. A door that requires a callback visit in year one for a seal failure or hardware adjustment costs you time. Our 365-Day Done Right Promise covers those callbacks at no charge – it is written into the job record, not a verbal assurance. That has a real dollar value when comparing total cost of ownership.

What the Installation Process Looks Like at Sightline
Understanding the steps helps you evaluate any contractor’s quote. Here is how a standard patio door installation runs at Sightline in West Palm Beach.
- Measured survey. A uniformed Sightline technician – background-checked, identified by license number before arrival per Haven Clause 3 – measures the rough opening, assesses the frame condition, documents the sill and head clearances, and photographs the existing installation. You keep a copy of that survey document.
- Written price, same document. The measurement and the quote are the same document under Haven Clause 1. You see the line items: product, glass specification, permit, labor, and any rough opening work. No separate “estimate” that changes when the installer arrives.
- Product order and permit application. Once the scope is signed, we order the product from the manufacturer and apply for the Palm Beach County permit concurrently. Lead times on impact-rated units from PGT, CGI, and CWS currently run three to six weeks from confirmed order; custom-width or multi-panel folding doors can run eight to twelve weeks.
- Installation day. The old door comes out, the rough opening is inspected and prepared, the new unit is set and shimmed, the frame is anchored per the product’s NOA installation instructions, and the glazing is sealed. A photo record is taken at each stage – this is the documented evidence record that travels with the job file, not an optional service.
- Inspection and close-out. The county inspector verifies the installation against the permit drawings. Once approved, the permit is closed and the documentation – including the NOA, the permit record, and the photo set – is compiled and provided to you. That package is what you hand to a future buyer’s inspector or insurance adjuster.
If anything in the installation does not meet the standard described in the written scope, the 365-Day Done Right Promise means we return and correct it. That commitment is stamped on every job, not offered selectively.
Sightline Windows & Doors in West Palm Beach: What We Install and Why It Matters
Sightline has been operating under the Haven Standard since 2012. Across more than 18,000 windows and doors installed, every job has started with a written price and ended with a documented photo record. Our Patio Door Installation in West Palm Beach service draws from eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – selected because they carry the product approvals Palm Beach County requires and because we have seen how they perform in South Florida’s salt air, UV load, and hurricane exposure over multiple seasons.
We do not have a preferred brand driven by margin. We specify by what the opening requires: the structural load, the code requirement, the glass performance target, and the budget the customer has given us in writing. If a CWS unit is right for a West Palm Beach home’s lanai opening, that is what goes on the quote. If PGT WinGuard is the better fit for a main living room door facing Flagler Drive’s water exposure, that is what we specify. The reasoning is in the written scope, not kept internally.
Sonia Raman leads the Sightline team in West Palm Beach. She built the local operation on the same founding principle the brand has held since 2012: the measurement and the quote are the same document, and the job is not finished until the photo record and documentation are in the customer’s hands. If you want to understand any line item in a Sightline quote, call and ask. Live phone coverage is available 24/7 – a person answers, not a queue.

FAQs: Patio Door Installation Cost in West Palm Beach
How much does it cost to install a patio door in West Palm Beach in 2026?
Most patio door installations in West Palm Beach run between $2,400 and $4,800 for a standard impact-rated sliding glass door, installed with permit. Non-impact doors start lower – around $1,200 to $2,100 – but require a separate storm protection solution to meet Palm Beach County code, which often closes most of that gap. Multi-panel folding doors start at $5,800 installed and increase with panel count and custom dimensions. Call (561) 354-3861 for a written price specific to your opening – the estimate is free.
Do I need a permit to replace a patio door in West Palm Beach?
Yes. Palm Beach County requires a building permit for any patio door replacement, new or like-for-like. The permit requires a Florida Product Approval number or Miami-Dade NOA for the door unit, a licensed contractor of record, and in some cases a signed and sealed installation drawing. The county fee runs $120 to $350. Sightline handles permit coordination as a standard part of every installation – it is included in the written scope, not billed separately after the fact.
Is it cheaper to repair or replace a patio door in West Palm Beach?
Repair is cost-effective when the frame is structurally sound and the issue is limited to hardware, rollers, or a compromised seal on a single glass unit. Roller replacement on a sliding patio door typically runs $150 to $350 in West Palm Beach. A seal replacement on a double-pane unit (to clear fogging between panes) runs $200 to $450. If the frame is corroded, the sill has water damage, or the glass does not carry a current impact rating, replacement is the more defensible choice both financially and for code compliance. We will tell you which category your door falls into on the measured survey – in writing, before any work starts.
How long does patio door installation take in West Palm Beach?
The installation itself – removing the old door, preparing the opening, setting and anchoring the new unit, and sealing – takes four to eight hours for a standard sliding glass door on a clean opening. Wider multi-panel installations run one to two full days. The total project timeline from signed scope to completed inspection is typically five to eight weeks, which includes the product lead time from the manufacturer (three to six weeks for stocked impact-rated lines) and the Palm Beach County permit and inspection cycle (four to seven business days in normal volume periods, longer after named storms).
What patio door brands does Sightline install in West Palm Beach?
We install and specify patio doors from PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. The right product for any given opening depends on the structural requirements, the impact rating needed, the glass performance specification, and the budget in the written scope. We do not push a single brand; we specify by what the opening requires. Each product we quote carries the Florida Product Approval documentation needed for Palm Beach County permitting, and we provide that documentation as part of the job record.
What does the 365-Day Done Right Promise cover on a patio door installation?
The 365-Day Done Right Promise covers any defect in workmanship or installation that appears within 365 days of completion. If the door does not operate correctly, if the seal fails because of how the unit was set, or if any installation detail does not match the written scope, we return and correct it at no charge. This is written into the Haven Standard on every Sightline job – not offered as a courtesy for certain price tiers or certain customers. Manufacturer warranty on the product itself is separate and runs according to each manufacturer’s published terms, which we include in the documentation package at job close-out.
