AfterHow Much Does Patio Door Installation Cost in Lantana?
Patio door installation in Lantana, FL typically costs between $1,200 and $4,800 installed, depending on door type, glass specification, and whether impact-rated glazing is required. Most Lantana homeowners replacing a standard single sliding patio door land between $1,800 and $2,800 for a mid-tier impact unit with labor included. Impact-rated french doors or large multi-panel pocket sliders at the higher end of the market can reach $6,500 or more once structural work and permit fees are factored in.

Patio Door Installation Cost Breakdown (2026)
The table below reflects what Lantana homeowners are actually paying in 2026, based on the openings Sightline has measured in this market. Prices include product, labor, basic permit fees where applicable, and standard disposal of the old door unit. They do not include structural framing changes, stucco repair, or hurricane shutter tracks, which are line-itemed separately on every written survey.
| Door Type | Product Tier | Installed Price Range |
|---|---|---|
| Single sliding patio door (6 ft) | Standard impact-rated (e.g., PGT WinGuard) | $1,800 – $2,600 |
| Single sliding patio door (8 ft) | Mid-tier impact, low-E glass | $2,200 – $3,200 |
| French patio doors (double, inswing) | Impact-rated, standard finish | $2,800 – $4,200 |
| French patio doors (double, outswing) | CGI or CWS impact unit | $3,000 – $4,800 |
| Multi-panel pocket/stacking slider (3+ panels) | ECO Window Systems or ViewLux | $4,500 – $7,500+ |
| Folding/bi-fold patio door | Custom, impact-rated | $5,500 – $9,000+ |
| Like-for-like sliding door swap (existing frame reused) | Entry-level impact unit | $1,200 – $1,800 |
What These Numbers Include
- Product cost: The door unit itself – frame, slab, glazing, hardware, and weatherstripping.
- Labor: Removal of the existing door, rough opening prep, installation, shimming, flashing, and caulking to Florida Building Code.
- Permit fees: Lantana requires a permit for door replacements that change the opening size or require structural modification. Standard like-for-like replacement permit fees in Palm Beach County typically run $75 – $175.
- Haul-away: The old door unit leaves with the crew.
What These Numbers Do Not Include
- Stucco patching around the frame exterior (add $150 – $400 depending on gap width)
- Interior drywall or trim repair if the opening is widened
- Hurricane shutter track installation or removal
- Screen door replacement if the existing screen is non-standard
- HOA documentation or impact certification letters (we provide these, but note the scope upfront)
Every one of those potential add-ons is listed as a separate line item on the written survey you receive before any work starts – Haven Clause 1 of the Sightline Haven Standard. The survey you keep and the invoice you pay are the same document.
What Affects Patio Door Installation Pricing in Lantana
Lantana sits directly between Lake Worth and Boynton Beach, less than a mile from the Intracoastal Waterway at several points. That geography matters for door pricing in ways that aren’t obvious until you’re holding a quote. Here’s what actually moves the number up or down.
- Impact rating and glass specification: Florida Building Code mandates impact-rated or protected openings in Wind-Borne Debris Regions, and most of Lantana qualifies. An impact unit costs more than a non-impact door, but it also eliminates the need for accordion shutters on that opening. Within impact glass, the SHGC (Solar Heat Gain Coefficient) and U-factor ratings affect energy performance and price – a door with a low SHGC (0.22 – 0.27) costs roughly 10 – 18% more than a standard-spec unit but meaningfully reduces cooling load in South Florida’s heat. We specify the rating on the written quote, not just the brand name.
- Proximity to salt air: Homes within half a mile of the Intracoastal – which covers much of east Lantana near the Hypoluxo Island area – require corrosion-resistant hardware and frame finishes. Marine-grade hardware on a sliding patio door adds $80 – $200 to the product cost but is not optional if you want the warranty to hold. We flag this during the measured survey.
- Opening size and structural condition: A 6-foot rough opening that is square, plumb, and dry costs less to install into than an 8-foot opening with water damage at the sill plate – something we see regularly in Lantana homes built in the 1970s and 1980s near the canal-adjacent streets off Hypoluxo Road. Sill repair, if needed, is estimated and written before the crew starts work.
- Door type and panel configuration: A single sliding door (two panels, one fixed) is the simplest installation. French doors with multi-point locking hardware take longer to set plumb and adjust. Stacking or pocket sliders with three or more panels require a pocket or header modification that adds framing labor. Each step up in complexity is reflected as a separate line item, not buried in a single lump-sum.
- Product line and manufacturer: Sightline specifies from eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – and the selection is based on what the opening requires, not what’s sitting in a warehouse. PGT WinGuard and CGI units are the most common impact-rated sliding door specifications in Lantana. Therma-Tru is typically specified for french-style door slabs where thermal performance is the priority. Prices vary across these lines by $300 – $900 for comparable opening sizes.
- Permit and inspection requirements: Palm Beach County requires a permit when a door replacement involves structural modification or a change in opening dimensions. The permit process adds time (typically 5 – 14 business days for residential permits in Lantana) and cost ($75 – $175 in fees). Like-for-like replacements using the same rough opening dimensions can sometimes qualify for a Notice of Commencement exemption, which we confirm during the survey. Either way, the permit status is documented on the written scope before work begins.
BeforeAfterPatio Door Costs by Neighborhood in Lantana
Lantana is a relatively compact city, but the stock of homes varies enough by area that pricing patterns differ from one block to the next.
East Lantana and Hypoluxo Island: Homes here often have direct water exposure and older construction, which means corrosion-resistant hardware is almost always required and sill conditions need to be assessed before pricing is finalized. We regularly find deteriorated sill plates in homes along the canal streets east of Federal Highway – the written survey always documents what we find before we touch anything.
West Lantana near Jog Road: Newer construction from the late 1990s through 2010s tends to have better-maintained rough openings and more standardized sizing, which keeps installation labor on the lower end of the range. The tradeoff is that some HOAs in this corridor have strict aesthetic requirements for door finishes and glass tint levels, which can limit product selection and occasionally adds a documentation step for HOA approval.
Central Lantana along Lantana Road: A mix of 1960s-1980s CBS (concrete block and stucco) construction where the rough openings were often built to non-standard dimensions. An 8-foot slider going into a 7’10” rough opening needs careful shimming and flashing work. We measure twice and document the as-found condition in the photo record before any modification.

Impact vs. Non-Impact Patio Doors in Lantana: The Cost Comparison
This question comes up on nearly every estimate we write in Lantana: is it worth paying more for impact glazing, or can a hurricane shutter cover the same opening for less?
The honest answer in numbers:
- A standard (non-impact) 6-foot sliding patio door, installed, runs approximately $900 – $1,400 in the Lantana market.
- The impact-rated equivalent runs $1,800 – $2,600 – roughly $700 – $1,200 more upfront.
- A new accordion hurricane shutter sized for a 6-foot opening costs approximately $600 – $1,100 installed.
So the non-impact door plus shutter route costs about the same as the impact door route in year one. The difference shows up in insurance credits (many Palm Beach County insurers offer meaningful premium reductions for fully impact-protected openings), maintenance over time, and daily usability – you don’t deploy a shutter every time a tropical system tracks through.
For Lantana homes that are already fully impact-protected on all other openings, adding an impact patio door to complete the protection envelope often qualifies the homeowner for a Florida Citizens or private insurer wind mitigation credit. We note this on the written survey but recommend verifying the credit amount directly with your insurer before making the decision based on it.
How to Save on Patio Door Installation in Lantana
There are real ways to reduce the cost of a patio door installation in Lantana without compromising on the things that matter – impact rating, proper flashing, and a finish that holds up to South Florida salt air. Here’s where the savings are actually available.
Get the Measured Survey Before You Commit to Anything
The single biggest source of surprise costs in door installation is the difference between what a salesperson quotes over the phone and what the opening actually requires when a crew shows up. Sightline’s measured survey and written price are the same document – you receive it before a tool is lifted. Call (561) 461-2062 for a free estimate and keep the written survey regardless of whether you book.
Bring a Competitor Quote for a Free Second Opinion
If you have a written estimate from another installer, bring it to us. Sightline offers a free second opinion on any written estimate. This isn’t a promise to beat the price – it’s a line-by-line review of what the other quote actually includes, what it omits, and whether the specified product is appropriate for your opening. Homeowners in Lantana have avoided significant surprises this way when a competing quote turned out to exclude permit fees, disposal, or required marine-grade hardware.
Match the Product to the Opening, Not to the Showroom
Eight manufacturer lines means we specify the product the opening requires. A 6-foot like-for-like slider on a well-maintained rough opening doesn’t need a top-of-line custom unit. The ES Windows or PGT WinGuard entry-level impact product handles that opening correctly and costs less than a CGI series unit that would perform the same function. We tell you this on the written survey.
Combine Openings When Possible
If you’re replacing a patio door and one or more windows in the same visit, the labor mobilization cost is spread across multiple openings. The per-opening cost drops. This is particularly relevant in Lantana’s older CBS homes where multiple openings may be approaching the same condition simultaneously.
Understand the Permit Requirement Before You Sign
A like-for-like replacement in the same rough opening, with no structural change, may qualify for a streamlined permit or an exemption that reduces both fees and timeline. We confirm this during the measured survey. Opting into an opening size change that triggers a full structural permit adds cost and time – knowing this upfront lets you make the decision with the numbers in front of you.
Check for Florida Energy Efficiency Rebates
Florida’s utility programs and certain federal energy efficiency credits may apply to patio doors meeting specific U-factor and SHGC thresholds. Doors specified at U-0.30 or lower and SHGC of 0.25 or lower tend to qualify. We list the glass specs on the written quote – you can use that document directly when filing for any applicable rebate.
What the Installation Process Looks Like at Sightline
Understanding what you’re paying for helps you evaluate any quote. Here’s the sequence on every Sightline patio door installation in Lantana.
- Measured survey: A background-checked, uniformed Sightline technician measures the rough opening, documents the existing frame and sill condition, and photographs the as-found state. The written price comes from this survey – not from a price sheet.
- Written scope and price: You receive a single document showing product specification (manufacturer, model, glass rating, hardware finish), labor scope, permit status, and total price. This is Haven Clause 1: Have it in writing. The number does not change.
- Permit filing: Where required, Sightline files the permit with Palm Beach County before scheduling the installation date. You don’t manage this step.
- Installation day: The crew arrives within the scheduled window – Haven Clause 2, Arrive on schedule. The existing door is removed, the rough opening is assessed against the survey findings, the new unit is set and shimmed, flashing and sealant are applied per Florida Building Code, and hardware is adjusted for operation and weather seal.
- Photo record: Every visit ends with a documented photo record – Haven Clause 4, Evidence on every job. You receive this as a standard part of the job record, not as an optional add-on.
- 365-Day Done Right Promise: If anything isn’t right within the first year – operation, seal, hardware, finish – we make it right under the Haven Standard. This is written into the job record, not offered verbally.
Since 2012, Sightline has installed and replaced more than 18,000 windows and doors in South Florida under this process. Every one of them started with a written price and ended with a photo record.
FAQs: Patio Door Installation Cost in Lantana
How much does a standard patio door installation cost in Lantana, FL?
A standard single sliding impact patio door installed in Lantana costs $1,800 – $2,600 for a 6-foot opening and $2,200 – $3,200 for an 8-foot opening. These ranges include the door unit, labor, permit fees where applicable, and haul-away of the existing door. French doors run $2,800 – $4,800 depending on configuration. Call (561) 461-2062 for a written price specific to your opening – the estimate is free.
Is a permit required for patio door installation in Lantana?
A permit is required in Lantana when the installation involves a structural change to the rough opening or a change in opening dimensions. Like-for-like replacements using the same rough opening may qualify for a streamlined permit or exemption, which Sightline confirms during the measured survey. Palm Beach County residential permit fees for this type of work typically run $75 – $175. Permit status and fees are written on the scope document before work begins – no surprises at the end of the job.
How long does patio door installation take in Lantana?
Most standard sliding or french patio door installations in Lantana take 3 – 6 hours for the physical installation once the permit is in hand. The total project timeline from signed scope to completed install is typically 1 – 3 weeks, with most of that window consumed by permit review at Palm Beach County. Like-for-like replacements that qualify for a permit exemption can sometimes be completed faster. The written scope will include the estimated timeline based on current permit queue conditions at the time of your survey.
Do I need an impact-rated patio door in Lantana?
Most of Lantana falls within a Wind-Borne Debris Region under Florida Building Code, which requires that all exterior openings be either impact-rated or protected by an approved storm shutter system. In practice, most Lantana homeowners replacing a patio door in 2026 are specifying an impact-rated unit to complete or maintain a fully protected envelope – particularly given the insurance premium implications. Impact patio doors in Lantana run $700 – $1,200 more than comparable non-impact units. We note the required specification and the insurance context on every written survey.
How do I know if I’m getting a fair price on a patio door in Lantana?
A fair price is a written price that itemizes product, labor, permit, and disposal separately – so you can see exactly what you’re paying for each component. If a quote gives you a single number without line items, you have no way to compare it accurately to another quote. Sightline offers a free second opinion on any written estimate: bring us a competitor’s quote and we’ll review it line by line at no charge. Call (561) 461-2062 to set that up.
Can Sightline replace just the sliding panel on my existing patio door frame?
Sometimes. If the existing frame is structurally sound, properly anchored, free of corrosion, and the existing product line is still in production, a panel-only replacement can cost $400 – $900 less than a full unit replacement. The measured survey will document the frame condition and confirm whether a panel swap is viable or whether the frame condition makes a full replacement the more cost-effective choice over a 5 – 10 year horizon. We give you both options in writing.
