How Much Does Custom Window & Door Order Cost in Three Lakes?
Custom window and door orders in Three Lakes, FL typically run between $850 and $6,200 per opening, depending on size, glazing type, frame material, and whether the unit needs to meet Miami-Dade impact ratings. Most Three Lakes homeowners replacing three to six windows with standard impact-rated custom units land somewhere between $4,500 and $14,000 for the full project, including professional installation. That number can climb significantly for large geometric openings, multi-panel sliding systems, or specialty glass with low SHGC values suited to South Florida’s heat load.
Custom Window & Door Order Cost Breakdown (2026)
Custom orders differ from stock replacements in one fundamental way: every dimension, glass package, and hardware finish is specified at the time of order, and the lead time reflects that. In Three Lakes, where older ranch homes and newer construction in subdivisions near Palmetto Bay Road often have non-standard rough openings, custom orders are more common than people expect. Below are the line-item ranges we see regularly in this market.
| Product Type | Unit Cost Range (materials only) | Installed Cost Range (per opening) |
|---|---|---|
| Custom impact single-hung window (up to 36″x60″) | $380 – $780 | $850 – $1,400 |
| Custom impact casement window (up to 36″x48″) | $420 – $920 | $950 – $1,650 |
| Custom impact picture/fixed window (large format) | $500 – $1,200 | $1,100 – $2,200 |
| Custom geometric/specialty window (trapezoid, arched, etc.) | $700 – $2,400 | $1,500 – $4,000 |
| Custom impact entry door (single) | $900 – $2,800 | $1,800 – $4,200 |
| Custom impact entry door (double/French) | $1,800 – $4,500 | $2,800 – $6,200 |
| Custom sliding/multi-panel patio door (2-panel) | $1,200 – $3,200 | $2,200 – $5,000 |
| Custom sliding/multi-panel patio door (3-4 panel) | $2,800 – $6,500 | $4,500 – $9,200 |
| Custom impact garage door (per door) | $1,400 – $3,800 | $2,000 – $5,200 |
Installation labor in Three Lakes runs $180 to $480 per opening for standard replacements. That number rises to $400 to $900 per opening when structural modifications are needed – framing adjustments, stucco patching around the new sightline, or concrete lintel work that older homes in this area sometimes require. Miami-Dade product approval documentation adds no cost to your invoice at Sightline; it is part of the measured survey the customer keeps from day one.
One more line item worth naming directly: permit fees. Miami-Dade County requires permits for window and door replacements that alter the opening size or involve impact-rated products. Permit costs in Three Lakes generally fall between $85 and $340 per permit, depending on valuation. We handle the filing; you see it on the written price before any work starts – Haven Clause 1, not a courtesy.
What Affects Custom Window & Door Order Pricing in Three Lakes

- Miami-Dade impact rating requirements: Three Lakes sits inside Miami-Dade County’s High Velocity Hurricane Zone (HVHZ), which means virtually every exterior window and door replacement must carry a Miami-Dade Notice of Acceptance (NOA). Impact-rated units from lines like Custom Window & Door Order in Three Lakes – drawing from PGT, CGI, CWS, and ES Windows – cost more than non-rated equivalents, but they also eliminate the need for separate shutter systems. In Three Lakes, this is the single biggest variable separating a $950 unit from a $480 one of comparable size.
- Glass package and SHGC value: South Florida’s heat load is real. A standard dual-pane unit with a Solar Heat Gain Coefficient (SHGC) of 0.40 performs very differently from a low-SHGC laminated unit at 0.22 or below. The lower the SHGC, the more the glass costs at the factory – typically adding $60 to $200 per unit depending on size. For homes on the west-facing lots near SW 128th Avenue, where afternoon sun loads the living areas hard, that upgrade pays back in FPL bills within a few years.
- Frame material: Extruded aluminum frames, standard across most South Florida impact lines, are priced differently from vinyl or fiberglass. ECO Window Systems and ES Windows both run aluminum frames at different price points. Vinyl frames from ViewLux cost less at the unit level but are less common in custom orders for Three Lakes homes with stucco exteriors, where aluminum’s rigidity handles thermal movement better. Expect aluminum to run 10 to 20 percent more than comparable vinyl on custom units.
- Opening size and shape: Standard rectangular openings are the cheapest to custom-order because glass cutting and frame fabrication follow predictable patterns. Arched tops, trapezoids, octagons, and other geometric shapes require custom frame extrusions or coped joints that add factory time and cost. A geometric window that would be $500 as a rectangle might be $1,400 as an arch – sometimes more, depending on the radius. Homes built in Three Lakes in the late 1980s and 1990s often have decorative arched transoms above entry doors that fall into this category.
- Number of openings ordered together: Custom orders placed as a batch – six or more units ordered at one time from the same manufacturer – typically reduce the per-unit cost by $40 to $120 per opening compared to ordering individual replacements. The factory setup cost is amortized across the run. If you are replacing most or all of your windows, ordering them together rather than in phases almost always produces a lower total cost.
- Existing rough opening condition: Three Lakes has housing stock ranging from 1960s CBS (concrete block construction) homes to townhomes built after 2005. Older CBS homes sometimes have rough openings that have settled or been patched in ways that require carpentry or stucco work before the new frame can be set plumb. Our measured survey documents the existing condition with photos before any order is placed – so if a lintel needs shimming or a sill needs to be rebuilt, that cost is written into the quote, not discovered on install day.
Before
AfterHow to Save on Custom Window & Door Order in Three Lakes
The most direct way to reduce cost on a custom order is to be precise about what you actually need versus what a showroom might default to. A few specific places where Three Lakes homeowners regularly find savings:
Order All Your Openings at Once
If you know you want to replace eight windows and two doors over the next two years, ordering them together rather than in two phases will almost always cost less per unit. Factory setup fees are real, and manufacturers like PGT and CGI price batch orders differently from one-off replacements. The written price reflects this at the survey stage – ask us to run both scenarios and you will see the dollar difference on the same document.
Match the Glass Package to the Opening’s Actual Exposure
Not every window in a Three Lakes home needs the same glass specification. A north-facing bedroom window carries a very different solar load than a southwest-facing great room window. Specifying a high-SHGC package (which costs less) on shaded or north-facing openings and reserving the low-SHGC, higher-performing glass for the west and south elevations can reduce total project cost by $400 to $900 on a typical six-to-eight window order without sacrificing comfort in the rooms that matter most.
Use Our Free Second Opinion on Any Written Estimate
If you have already received a written quote from another installer, bring it to us. We will review it at no charge – line by line, product spec against product spec. We do this not as a sales tactic but because Haven Clause 1 (Have It in Writing) only works if the customer actually understands what they are agreeing to. In practice, we find that roughly half of the competitor quotes we review are missing the permit fee, misidentifying the glass package, or specifying a product without Miami-Dade NOA for an HVHZ installation. That matters before you sign, not after.
Ask About Lead Time Flexibility
Custom orders from our eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – have lead times that vary by factory and season. If you are not on an urgent timeline, specifying a manufacturer whose production queue is shorter at the time of order can occasionally reduce freight costs and, in some cases, allow us to batch your order with other Three Lakes jobs scheduled that month. We document this in the written scope so you see the logic, not just the number.
Get the Measured Survey Before You Commit to Anything
At Sightline, the measured survey is the quote. The technician who measures your openings is producing the document you keep – the same one that becomes your invoice if you move forward. There is no charge for that document, and you are not obligated to proceed. Call (786) 808-5792 to schedule yours; we answer live, not through a callback queue. A precise measurement up front is the single best way to avoid cost surprises on a custom order, because there are no change orders on a unit that was built exactly to the field dimensions.
The Sightline Process for Custom Orders in Three Lakes

Understanding the cost of a custom order is easier when you know how the process actually works from the first call to the final photo record. Here is what a standard custom window and door order looks like when it goes through our process in Three Lakes.
Step 1: Measured Survey
A background-checked, uniformed Sightline technician – identified by license number before arrival, per Haven Clause 3 (Verified Crews) – visits your Three Lakes home and measures every opening to be replaced. These measurements are recorded on the survey document you keep. If the existing opening has a condition that will affect installation cost (damaged framing, stucco irregularities, concrete lintel adjustments), it is photographed and noted in the same document. This is not a sales visit; it is a technical visit that produces a written record.
Step 2: Written Price Before Any Work Starts
The measured survey becomes the price document. Product line, glass package, frame specification, Miami-Dade NOA number, installation scope, permit fees, and project timeline are all written on the same page. Haven Clause 1 (Have It in Writing) means this document cannot change between the quote and the invoice – if we quoted it, we stand behind it. Sonia Raman has run every Sightline project under this principle since 2012, and it has governed all 18,000+ openings the company has installed.
Step 3: Order Placement and Lead Time
Once you approve the written price, we place the factory order. Custom lead times from our manufacturer lines typically run 4 to 14 weeks depending on product complexity, glass specification, and current factory queue. We document the expected delivery window in the written scope – no verbal estimates, nothing approximated after the fact.
Step 4: Installation and Photo Record
On installation day, the crew arrives on the scheduled date – Haven Clause 2 (Arrive on Schedule). Every completed opening is photographed as part of the documented photo record included on every job as standard evidence. You receive this record at project close. The 365-Day Done Right Promise covers every installed unit: if it is not done right, we make it right – written into the Haven Standard, not offered as a courtesy.
Custom Window vs. Stock Window: Is the Price Difference Worth It in Three Lakes?
This is one of the most common questions we field from Three Lakes homeowners, and it deserves a direct answer. Stock windows are manufactured to common nominal sizes – 24″x36″, 30″x48″, and so on – and are priced lower because the factory runs them in volume. Custom windows are built to the exact field-measured dimensions of your rough opening.
In Three Lakes, the housing stock makes stock sizing less reliable than it might seem on paper. Homes built in the 1970s and 1980s often have rough openings that are slightly off-nominal due to original construction tolerances or decades of minor settling. A 30″x48″ nominal stock window dropped into a rough opening that measures 29-3/4″ x 47-1/2″ requires shimming and filler strips that, done correctly, add labor time, and done incorrectly, create air infiltration paths and glazing failures within a few years. A custom unit ordered to 29-3/4″ x 47-1/2″ fits clean, seals clean, and performs to spec.
The cost difference between a stock unit and a custom unit of comparable quality from the same manufacturer is typically $80 to $250 per opening. In most Three Lakes installations we have completed in older CBS construction, that premium is recovered in labor savings and avoided callbacks. The math is documented in the survey – ask us to show you both numbers on the same page.
Manufacturer Lines and What They Cost in the Three Lakes Market

Sightline draws from eight verified manufacturer lines, and each one sits at a different price point for custom orders. Here is a plain-English summary of where each line lands:
- PGT Innovations: The most widely specified impact line in South Florida. Custom PGT units run $420 to $1,100 per unit before installation for standard rectangular openings. Miami-Dade NOA coverage across virtually the entire product range. Strong lead time predictability from the Venice, FL factory.
- CGI Windows & Doors: Positioned slightly above PGT on custom and high-performance specs. Custom CGI units typically run $480 to $1,400 per unit. CGI’s aluminum extrusions are notably rigid, which is relevant in Three Lakes homes with masonry openings that require tight tolerances.
- CWS (Custom Window & Door Systems): A strong option for large-format custom openings and multi-panel sliding systems. Pricing for custom CWS units runs $550 to $2,200 per unit depending on size and glass specification.
- ES Windows: Competitive pricing on impact-rated aluminum custom windows. ES units typically run $380 to $980 per unit for standard custom sizes. A practical choice for whole-home replacement projects where budget per opening matters.
- ECO Window Systems: Miami-based manufacturer with quick lead times on custom orders, relevant for Three Lakes jobs on tighter timelines. Custom ECO units run $360 to $920 per unit.
- Mr-Glass: Specialty and high-end custom glazing, including large-format fixed units and geometric configurations. Pricing varies more widely – $600 to $3,500+ per unit – because the product range covers genuinely complex custom work.
- Therma-Tru: The primary line we specify for custom entry doors – fiberglass and steel units with impact-rated configurations. Custom Therma-Tru entry doors run $900 to $3,200 per unit before installation.
- ViewLux: Vinyl-framed units at a lower price point, useful for interior applications or non-HVHZ openings where impact rating is not required. Custom ViewLux units run $280 to $680 per unit.
Which line is right for your Three Lakes project depends on the opening requirements, not on what is in stock at the warehouse. The measured survey document specifies the product line and the reason for the specification – you see the logic, not just the label.
FAQs – Custom Window & Door Order Cost in Three Lakes
How much does a custom impact window cost in Three Lakes, FL?
A custom impact window in Three Lakes typically costs between $850 and $2,200 installed, depending on size, glass package, and frame specification. Single-hung and fixed picture windows sit at the lower end of that range; large casements, geometric shapes, and units with very low SHGC glass specifications sit higher. For an exact number tied to your specific rough opening dimensions, call (786) 808-5792 – the measured survey is free and produces a written price on the same visit.
How much does a custom impact entry door cost in Three Lakes?
Custom impact entry doors in Three Lakes run $1,800 to $4,200 installed for a single door and $2,800 to $6,200 for a double or French configuration. Those ranges cover standard Therma-Tru fiberglass and CGI aluminum units with Miami-Dade NOA. Sidelites, decorative glass inserts, and custom hardware finishes push cost toward the upper end. Permit fees ($85 to $340 depending on project valuation) are included in the written price before any work starts – never added afterward.
How long does a custom window or door order take in Three Lakes?
Custom orders placed through Sightline in Three Lakes typically arrive from the factory in 4 to 14 weeks after order confirmation. PGT and ECO Window Systems generally sit at the shorter end of that range for standard custom sizes; large-format CWS sliding systems and specialty Mr-Glass geometric units run closer to the 10-to-14-week window. The expected delivery date is written into the project scope at the time of the quote – not estimated verbally.
Do I need a permit for a custom window replacement in Three Lakes?
Yes, in nearly every case. Three Lakes falls within Miami-Dade County’s jurisdiction, and the county requires permits for window and door replacements involving impact-rated products or any change to opening size. Permit fees run $85 to $340 per permit in this market depending on project valuation. Sightline handles the permit application; the fee appears on your written price before any work begins. Products we install carry valid Miami-Dade NOA documentation, which is required for HVHZ permit approval.
Is it cheaper to repair an existing window or order a custom replacement in Three Lakes?
Repair is cheaper in the short term – a broken seal or failed hardware fix typically runs $120 to $380. But in Three Lakes, most repair calls on windows older than 12 to 15 years involve units that no longer meet current Miami-Dade HVHZ requirements, meaning a repaired window may still fail a permit inspection or insurance inspection. A custom replacement that carries a current NOA costs more upfront but resolves both the performance issue and the compliance gap. If you have a written estimate for repair, bring it to us; we will review it at no charge and give you the comparison in writing.
Can Sightline match a non-standard opening size from an older Three Lakes home?
Yes. Non-standard rough openings are one of the primary reasons custom orders exist, and they are common in Three Lakes housing stock built before 1990. The measured survey captures the exact field dimensions – to the eighth of an inch – and the factory order is placed to those dimensions. There is no shimming to nominal size, no filler strips, no gap-filling caulk as a substitute for a proper fit. The written price reflects the exact product spec before anything is ordered.
