How Much Does Custom Window & Door Order Cost in Lantana?

Custom window and door orders in Lantana, FL typically run between $850 and $6,200 per opening, depending on size, glazing type, framing material, and whether the unit needs to meet Florida’s impact-rated standards. Most Lantana homeowners ordering a single custom impact window land in the $1,100-$2,800 range, while a full custom entry door system with sidelights and a transom sits closer to $3,500-$6,200 installed. At Sightline Windows & Doors, the measured survey and the written price are the same document – you see every number before a tool is lifted, in keeping with Haven Clause 1.

Custom Window & Door Order Cost Breakdown (2026)

The table below reflects actual pricing in the Lantana market as of 2026. These figures include the unit, hardware, installation labor, and the documented photo record Sightline leaves on every completed job. They do not include permit fees, which in Lantana and Palm Beach County generally add $75-$350 per permit pull depending on scope.

What Pushes the Price Up

The single biggest cost driver on a custom order is the glass specification. In Lantana and coastal Palm Beach County, most projects require impact-rated laminated glass – a polyvinyl butyral (PVB) interlayer sandwiched between two glass lites – to satisfy Florida Building Code and qualify under the Palm Beach County wind-load schedule. That glass alone can represent 40-55% of the unit cost on a large opening. Add a low-e coating to bring the U-factor down and the solar heat gain coefficient (SHGC) into compliance with Florida Energy Code, and you’re looking at another $80-$180 per unit.

Frame material is the second variable. Aluminum frames – the standard in South Florida for good reason, given salt air – run less than fiberglass, but thermally broken aluminum profiles cost more than non-thermally-broken ones. Fiberglass frames from lines like ViewLux carry a premium but expand and contract at nearly the same rate as glass, which matters in Lantana’s humidity swings between January and August.

Non-standard sizing is where costs accelerate fastest. A rectangular window that a manufacturer stocks in a close-enough rough opening size costs much less than one fabricated to a precise field measurement. On older Lantana homes – particularly the block construction built through the 1970s and 1980s in areas like Lantana Road corridor and near Lake Osborne – openings almost never match a stock dimension. Every deviation from a catalog size is a fabrication order, not a pick-from-shelf order, and that affects both price and lead time.

What Keeps the Price Down

Ordering multiple units at once is the clearest path to a lower per-unit cost. Manufacturers set minimum order quantities for custom fabrication, and a four-window order clears those thresholds in a way a single window does not. When Sightline scopes a full home in Lantana – say, a 1,900-square-foot concrete block house with eight openings – the per-unit fabrication cost is typically 12-20% lower than the same windows ordered one at a time.

Choosing a non-impact line where code genuinely permits it also reduces cost. If a Lantana homeowner has code-compliant impact shutters already installed and wants to upgrade glass for energy efficiency only, a product like ECO Window Systems’ thermal series can perform to Florida Energy Code without the laminated glass premium. That’s a conversation worth having before spec’ing everything in the premium tier.

What Affects Custom Window & Door Order Pricing in Lantana

• Florida Building Code wind-load requirements: Lantana sits in a High-Velocity Hurricane Zone (HVHZ) designation under Palm Beach County’s wind speed map, which means every new or replacement window and door must meet the 160+ mph design pressure specifications. Products that carry a Florida Product Approval number – required for permit issuance – cost more to fabricate than non-rated equivalents. PGT, CGI, and CWS all carry broad Florida Product Approval coverage; that’s part of why Sightline specifies from those lines.
• Opening geometry and field conditions: Older Lantana homes, especially those built before 1990 near Hypoluxo Road and the sections west of US-1, frequently have out-of-plumb frames, settled sills, or non-standard rough opening heights left by decades of South Florida humidity cycles. Field conditions that require shimming, buck work, or header reinforcement add labor – typically $150-$500 per opening depending on severity. Sightline’s measured survey documents these conditions before the quote is finalized, so they don’t surface as a surprise on the invoice.
• Glass specification (U-factor, SHGC, laminate type): Florida Energy Code sets maximum SHGC values – 0.25 for most residential openings in Climate Zone 1, which covers Lantana. Meeting that threshold in a large west-facing opening in a Lantana home often requires specifying a high-performance low-e coating that goes beyond base impact glass. Each step up in glass performance adds cost but also improves the long-term energy math, especially given Lantana’s average of 233 sunny days per year and cooling-dominated energy profile.
• Frame material and finish: Standard extruded aluminum is the baseline. Thermally broken aluminum adds insulating fins between the interior and exterior frame faces, reducing condensation and improving the U-factor – relevant for air-conditioned Lantana homes where the delta between inside and outside temperature can run 25-30 degrees for months at a time. Anodized or powder-coat finishes in non-standard colors add a per-unit upcharge, usually $60-$140 depending on frame size.
• Lead time and fabrication source: Custom orders from Florida-based fabricators like PGT (Nokomis, FL) and CGI (Miami, FL) typically ship in 4-8 weeks on standard custom specs. Highly non-standard profiles – radius corners, unusual frame depths, multi-point locking door systems with custom panel configurations – can push lead time to 10-14 weeks. Rush fabrication, when available, carries a surcharge. Most Lantana jobs Sightline handles fall in the 5-7 week window from signed scope to delivery.
• Permit requirements and inspection scheduling: Palm Beach County requires a permit for window and door replacements that change the opening size or require structural work. The permit fee is only part of the equation; the inspection schedule affects project duration. Lantana’s building department typically schedules inspections within 3-5 business days of request, which is faster than some neighboring municipalities, but structural inspections for header modifications can require a second visit. Sightline manages the permit pull and inspection coordination as part of the written scope.

How to Save on Custom Window & Door Order in Lantana

Bundle Openings Into One Project

If your Lantana home needs more than two custom windows or doors, ordering them together almost always reduces the per-unit cost. Fabricators price custom runs differently than single units – the setup cost is amortized across more pieces, and shipping a single delivery from a manufacturer like PGT in Nokomis is less expensive per unit than two separate shipments. On a recent Lantana project involving six custom impact windows and a sliding glass door, bundling all seven units into one order saved the homeowner roughly 15% compared to the staged pricing on individual orders.

Match the Product Tier to the Opening’s Actual Requirement

Not every opening in a Lantana home needs the top-tier glass specification. A small bathroom window on the interior of the structure, protected by a covered soffit, may only need to meet base impact requirements – not the premium low-e coating required for a large south-facing picture window. Sightline’s measured survey identifies each opening’s actual code requirement and exposure condition, which means you’re not paying for a high-performance spec where a standard-performance spec is sufficient.

Take Advantage of the Free Second Opinion

If you’ve already received a written estimate from another Lantana contractor, bring it to Sightline. We’ll review any written competitor quote at no charge, line by line, and tell you whether the product specs match what the opening actually requires, whether the pricing reflects the current Lantana market, and whether anything looks missing. That review costs nothing and takes about 20 minutes. Call (561) 461-2062 to schedule it.

Ask About Florida Energy Code Compliance Credits

Replacing single-pane or clear-glass windows with Florida Energy Code-compliant low-e impact units can qualify Lantana homeowners for utility rebates through Florida Power & Light’s home improvement program. The amounts are modest – typically $25-$75 per window – but on a full-home replacement, that adds up. FPL’s program requirements change annually; we’ll note during the survey whether your project’s glass spec qualifies and what documentation you’ll need.

Review the Scope Before Fabrication Starts

The most expensive thing you can do on a custom order is change the specification after fabrication has begun. Custom-fabricated windows and doors are built to your exact field measurements – a 47.25″ wide impact casement cannot be returned to stock or resold. Before Sightline places a fabrication order, the written scope goes back to you for review. That’s not a formality; it’s the point where catching a specification error costs nothing.

FAQs – Custom Window & Door Order Cost in Lantana

How much does a custom impact window cost in Lantana, FL?

A custom impact window in Lantana typically costs $850 to $2,400 installed, depending on size, opening shape, and glass specification. Single-hung impact windows in standard rectangular shapes run toward the lower end of that range. Casement windows, larger picture units, or openings requiring high-performance low-e glass to meet Florida Energy Code push toward the higher end. The price you receive from Sightline includes the unit, installation labor, hardware, and the documented photo record – written before any work starts. Call (561) 461-2062 for a free estimate on your specific openings.

How much does a custom impact door cost in Lantana?

Custom impact entry doors in Lantana run $2,800 to $5,600 installed for a single door, and $3,500 to $6,200 for a full surround with sidelights and a transom. Sliding glass doors in impact-rated configurations fall between $2,200 and $5,400 depending on panel width and frame spec. The variables that move cost most are panel configuration, glass lite size, finish color, and whether the existing header requires structural modification to accept the new unit. Call (561) 461-2062 and we’ll walk through the opening conditions with you before committing any numbers to paper.

How long does a custom window or door order take in Lantana?

Most custom orders placed through Sightline in Lantana ship from the manufacturer in 4-8 weeks, with 5-7 weeks being the most common range for standard custom specs from PGT, CGI, or CWS. Highly non-standard profiles – geometric windows, multi-panel door systems with custom configurations, or finishes outside the standard powder-coat palette – can extend lead time to 10-14 weeks. Installation itself typically takes one to three days depending on scope. The written scope you receive before fabrication starts will include the estimated lead time, so you’re not guessing.

Do I need a permit for a custom window or door replacement in Lantana?

Yes, in most cases. Palm Beach County requires a building permit for window and door replacements that alter the opening size or involve structural modifications – and custom orders frequently involve at least minor frame adjustments. Permit fees in Lantana and Palm Beach County generally run $75-$350 per permit pull depending on project scope. Sightline handles the permit application and inspection coordination as part of the written scope; you don’t manage that separately. Permits that are properly pulled also protect you at resale – unpermitted window and door work in Palm Beach County can surface as a title issue and is a material disclosure requirement under Florida law.

Is it cheaper to use a stock window or order a custom one?

Stock windows run 20-35% less per unit than custom-fabricated equivalents, but only when a stock size fits your opening. In Lantana’s older housing stock – particularly the concrete block homes built in the 1960s through 1980s around Lake Osborne Drive, Lantana Road, and the streets running south toward Hypoluxo – opening dimensions routinely fall outside standard manufacturer catalog sizes. Forcing a stock unit into a non-standard opening requires filler strips, non-standard shimming, or a narrowed sightline that affects both performance and appearance. In those cases, a custom-fabricated unit is not the premium option; it’s the correct option. Sightline’s measured survey will tell you clearly which openings can accept a stock size and which cannot. Call (561) 461-2062 to schedule that survey at no charge.

What manufacturers does Sightline use for custom orders in Lantana?

Sightline specifies from eight manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. The manufacturer specified for a given opening depends on what that opening requires – its code exposure category, the required design pressure rating, the glass performance spec, and the frame dimension – not on what’s in stock or what carries the highest margin. PGT and CGI cover most impact window and door needs; Therma-Tru handles custom entry door configurations; ECO Window Systems and ViewLux work well for energy-efficient applications where impact glass is not the primary requirement. You’ll see the manufacturer and product line named on the written scope, not just a generic description.

What You Receive From Sightline on Every Custom Order

Custom window and door orders are long-lead purchases. A lot can go wrong between the initial site visit and the day the units arrive and get installed – and most of what goes wrong does so because the original scope was vague, the field measurements weren’t precise, or the written price and the final invoice were different documents. At Sightline, those three things don’t happen because the Haven Standard governs every step.

Here’s what the engagement looks like, in plain terms:

• Measured survey you keep: Sightline’s technician measures every opening to field tolerance, notes frame condition, sill condition, and any structural observations. You receive a copy of that document. It is the basis for everything that follows – Haven Clause 1.
• Written price before fabrication: The written scope lists every unit by manufacturer, product line, size, glass spec, and installed price. The fabrication order goes out only after you’ve reviewed and approved that document. No work starts before the price is on paper – this is the whole point of Haven Clause 1 (Have It In Writing).
• Background-checked, uniformed technicians: Every Sightline technician is background-checked and identified by license number before arrival – Haven Clause 3 (Verified Crews). You know who is coming to your Lantana home before they arrive.
• Documented photo record: Installation photos are taken before, during, and after every job and included in the completion record – Haven Clause 4 (Evidence on Every Job). If a question arises in six months about how a unit was installed, the answer is in the record, not in someone’s memory.
• 365-Day Done Right Promise: If anything about the installation is not right within 365 days of completion, Sightline makes it right – written into the Haven Standard, not offered as a verbal assurance.
• Free second opinion on written estimates: If you have a written quote from another Lantana contractor, we’ll review it at no charge. Bring the document; we’ll go through it line by line.

These aren’t upsells. They are included on every job because the Haven Standard doesn’t have a tier structure – it applies to a single custom window the same way it applies to a full-home replacement.

Why Lantana Homeowners Order Custom Units (and When Stock Sizes Don’t Cut It)

Lantana’s housing stock is a study in a particular kind of Florida construction: concrete block homes built fast between 1955 and 1985, when standard residential dimensions weren’t as standardized as they are today. Walk through most neighborhoods between Lake Osborne and the Intracoastal and you’ll find rough opening heights that differ by floor, window sills that have moved as the slab settled, and original aluminum jalousie frames replaced once or twice already with whatever fit at the time.

That history creates a market where custom fabrication isn’t a luxury – it’s frequently the only way to get a properly fitting, code-compliant unit. A window that’s an inch too narrow leaves a gap that no amount of trim conceals properly and that a Palm Beach County inspector will flag. A door that’s a quarter-inch too tall binds on the threshold within one South Florida summer. Sightline’s measured survey catches those conditions before the fabrication order goes to PGT or CGI, not after the unit arrives on a truck.

For newer construction in Lantana – homes built in the subdivisions closer to Hypoluxo Road or in the more recent developments along the south end of town – stock sizes often fit. But even there, a homeowner who wants a non-standard configuration (a wider sliding door to open the living space to a pool deck, a radius window above a front entry, a custom-width casement to match an existing opening that was itself custom) ends up in custom territory regardless of the home’s age.
