New Window Installation Cost - Written Price Before Anything Is Ordered

How Much Does New Window Installation Cost in Hobe Sound?

New window installation in Hobe Sound, FL typically costs between $420 and $1,850 per window, all-in, when you factor in the unit, labor, and any trim or flashing work. Most Hobe Sound homeowners replacing a standard double-hung or casement window in an existing opening pay somewhere in the $600-$1,100 range per opening – impact-rated glass, which Martin County building code effectively requires for most new installations, pushes that figure toward the higher end. For a full home with 12 to 18 windows, total project costs generally land between $8,500 and $24,000 depending on window type, frame material, and glazing specification.

At Sightline Windows & Doors, every price is written before any work starts – that’s Haven Clause 1, and it’s the whole point. What follows is a plain-English breakdown of what drives those numbers in this specific market.

New Window Installation Cost Breakdown in Hobe Sound (2026)

New window installation in Hobe Sound costs $420 to $1,850 per window installed, depending on window type, frame material, glazing package, and opening complexity. The table below reflects current pricing for the Hobe Sound, FL market – not national averages pulled from a trade publication. These are the ranges we see on actual measured surveys in this zip code.

A few Hobe Sound-specific cost notes: Martin County requires a permit for new window installations, and the permit fee typically adds $75 to $220 per project depending on scope – that’s separate from labor. If your home was built before 1995, you may encounter single-wythe block construction with non-standard rough opening dimensions; re-framing or buck-trimming in those cases adds $80 to $180 per opening. And because Hobe Sound sits within Martin County’s High Velocity Hurricane Zone (HVHZ) designation, any window product installed here must carry a current Florida Product Approval (NOA) number – that’s a document Sightline provides before any crew shows up, not something you have to chase down yourself.

The product line matters too. We specify from eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – and the right product for a Hobe Sound home isn’t always the most expensive one in the catalog. A PGT WinGuard vinyl unit often hits the right balance of price, performance, and Florida Building Code compliance for a standard residential opening. CGI units carry a higher price point but are appropriate where design pressure ratings or custom sizing push beyond what a standard line handles.

What Affects New Window Installation Pricing in Hobe Sound

Six factors move the number up or down more than anything else. Each one applies specifically to homes in this market – not generic advice from a national pricing guide.

• Impact vs. non-impact glazing. Florida’s building code and Martin County’s local amendments make impact-rated glazing effectively mandatory for most new window installations in Hobe Sound. A non-impact window paired with a code-compliant storm shutter system is a legal path, but most homeowners on the Treasure Coast are moving away from that approach for practical reasons. Impact glass – typically laminated, dual-pane construction with a PVB or SGP interlayer – adds $80 to $200 per unit compared to a comparable non-impact unit, but it’s the right spec for this climate.
• Frame material. Vinyl frames dominate new installations in Hobe Sound because they resist the salt air and UV exposure that come with being a mile from the Intracoastal. Aluminum frames cost slightly less upfront but require more maintenance here and can transfer more heat – a real concern when you’re managing SHGC (solar heat gain coefficient) in a south-facing room in a South Florida summer. Fiberglass frames are premium: they run 20-40% more than vinyl but hold dimensional stability better in the heat cycling Hobe Sound sees from June through September.
• Window size and design pressure rating. Larger openings need products rated for higher design pressures – the DP rating stamped on the unit’s Florida Product Approval. Oceanside and Intracoastal-adjacent homes in Hobe Sound, particularly in neighborhoods like Loblolly Pines and the waterfront lots along Southeast Bridge Road, often need DP-50 or higher-rated units. That spec isn’t a recommendation; it’s a code requirement that the permit inspector will verify.
• Opening condition and existing construction. CBS (concrete block structure) homes are common in Hobe Sound, and cutting or enlarging an opening in block costs more than the same work in wood-frame construction. If the buck (the wood sub-frame in the block opening) is rotted from moisture intrusion – something we see regularly in homes built in the 1970s and 1980s near the water – replacement adds $80 to $220 per opening before the window goes in.
• Number of windows ordered together. Project size affects unit cost. Ordering 12 windows at once typically brings the per-unit product cost down $30 to $80 compared to a single-window order, and labor runs more efficiently across a full-day installation. We see this consistently when homeowners in the Gomez, North River Shores, and Poinciana Gardens areas do a whole-home window upgrade rather than replacing one at a time.
• U-factor and energy efficiency specification. Florida’s energy code requires a maximum U-factor of 0.65 for fenestration in Climate Zone 1 (which covers Martin County). Most current impact products from our manufacturer lines hit that threshold, but if you’re targeting a lower U-factor for energy savings – say, 0.30 or below for a room facing southwest – the unit cost rises accordingly. The SHGC target for South Florida is typically 0.25 or lower; that spec directly affects which glass package you order and what you pay for it.

Hobe Sound Market Notes: Why Local Pricing Differs From National Averages

National pricing guides cite $300 to $700 per window installed. Those numbers are built on averages from markets like Phoenix, Cleveland, and Atlanta – markets with no hurricane code requirements, lower permitting costs, and no HVHZ designation. They’re not useful here.

Hobe Sound is in Martin County, a county that enforces its own local amendments on top of the Florida Building Code. The permit process involves both plan review and a field inspection – both are required for new window installations, and neither can be skipped. The permit cost, typically $75 to $220 for a residential window project, is a real line item on your invoice. Any contractor who quotes you a window installation in Hobe Sound without a permit fee on the written price is either planning to pull permits separately (ask them directly) or not pulling them at all. With Sightline, the permit cost is included in the written scope before work starts – Haven Clause 1 isn’t a marketing phrase, it’s how the document is structured.

The salt air environment along the Treasure Coast also shortens the serviceable life of certain frame materials and hardware that perform adequately inland. We specify products rated for coastal exposure – that means marine-grade hardware, corrosion-resistant fasteners, and frame materials with UV-stabilized finishes. The spec costs slightly more upfront; it costs considerably less over a 15-year horizon than replacing hardware every few years.

If you’re comparing quotes for new window installation in Hobe Sound, the single most useful question to ask every contractor is: “Can I see the Florida Product Approval number for the unit you’re quoting?” A number means the product has been tested and certified for this state’s wind load requirements. No number means it hasn’t, and that’s a building code problem that lands on the homeowner when the permit inspector shows up.

How to Save on New Window Installation in Hobe Sound

A few practical moves make a real difference on the final invoice – none of them involve cutting the specification to a product that won’t hold up in Martin County’s wind environment.

• Do all the windows at once. A single mobilization, a single permit application, and a single measured survey covers every opening. Splitting the project across two or three visits costs more in labor and permitting than most homeowners expect. If budget is the constraint, ask us to write the scope for the full project and phase the work by priority – we can structure that in the written quote.
• Know your SHGC requirements before you spec the glass. The glass package is one of the bigger cost levers. A 0.25 SHGC package costs more than a 0.27 package, and in many Hobe Sound applications the difference in actual energy performance is marginal. We’ll tell you what the numbers mean in real terms for your orientation and square footage – not just quote the higher-end glass because it’s available.
• Check for utility rebates. Florida Power & Light (FPL) has offered rebates for qualifying high-efficiency window installations in the past. The program terms change, but it’s worth confirming current eligibility before finalizing your glass spec. We can point you to the current FPL program details; we don’t inflate the energy savings numbers to make the sale.
• Get a second opinion on any written quote you already have. Sightline offers a free second opinion on any written estimate from another contractor. Bring us the document – we’ll review the product spec, the labor breakdown, and the permit line, and tell you whether the number is reasonable for the Hobe Sound market. There’s no obligation and no pressure.
• Match the product line to the opening, not to the showroom. Not every opening in your home needs a premium CGI unit. A south-facing bedroom window in a CBS home in the Poinciana Gardens area may be perfectly served by a PGT WinGuard vinyl unit at a lower price point. We specify from eight lines for exactly this reason – the product follows the opening requirement, not the other way around.
• Plan for the permit timeline. Martin County permit review timelines can run two to four weeks for residential window projects. Planning the project with that lead time in mind means you’re not paying for expedited processing or facing delays on a job that’s already scheduled. We handle permit applications as part of every scope – it’s on the written document before work starts.

FAQs – New Window Installation Cost in Hobe Sound, FL

How much does a single new window installation cost in Hobe Sound?

A single impact-rated window installation in Hobe Sound typically costs $420 to $1,100 for a standard opening, including the unit, labor, and trim work. Bay, bow, or custom geometric windows run higher – $1,280 to $2,820 for those configurations. The Martin County permit fee ($75 to $220) applies to the project, not per window, so it’s proportionally cheaper on multi-window projects. Call (772) 362-5967 for a written quote on your specific opening – estimates are free.

Do I need a permit for new window installation in Hobe Sound, FL?

Yes. Martin County requires a permit for new window installations, and that includes direct-set replacements into existing openings when the product or size changes. The permit involves both a plan review (where the Florida Product Approval number is verified) and a field inspection after installation. The fee is typically $75 to $220 for a standard residential project. Sightline handles the permit application as part of every scope – it’s a line item on the written price, not something that appears later.

What is the difference in cost between impact and non-impact windows in Hobe Sound?

Impact-rated windows cost roughly $80 to $200 more per unit than comparable non-impact products. In Hobe Sound, Martin County’s HVHZ designation means that new installations effectively require either impact-rated glass or a code-compliant storm shutter system for each opening. Most homeowners on the Treasure Coast choose impact glass because it covers the opening without requiring you to deploy and store shutters before every storm. The long-term math typically favors impact glass for any home planning to stay in place for ten or more years.

How long does new window installation take in Hobe Sound?

Installation itself moves faster than most homeowners expect: a crew typically sets six to ten standard windows in a single day. The longer timeline is the permit process – Martin County plan review for residential windows currently runs two to four weeks. The full project timeline from signed scope to final inspection is usually three to six weeks, with the permit review accounting for most of that. Sightline submits permit applications promptly after the written scope is signed; the timeline is on the document so there are no surprises.

Is it cheaper to repair or replace windows in Hobe Sound?

For windows built before 2005 in Hobe Sound, replacement is usually the better financial decision. Pre-2005 windows rarely meet current Florida Building Code wind load requirements, SHGC standards, or U-factor minimums – which means a repair keeps a non-compliant product in place and may not satisfy permit requirements anyway. If your window is post-2010, impact-rated, and has a specific defect (seal failure, hardware issue, minor frame crack), repair may cost $80 to $250 and extend useful life. For anything older, or for multiple windows with similar problems, replacement at current market pricing typically pays back in energy savings and storm protection within seven to ten years. Call (772) 362-5967 and we’ll give you a straight read on whether your specific window warrants repair or replacement – at no charge.

What brands of windows does Sightline install in Hobe Sound?

Sightline specifies from eight manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Each carries a current Florida Product Approval, and each is specified based on what the opening requires – design pressure rating, size, U-factor target, and budget – not by what happens to be in stock. PGT WinGuard vinyl is the most common specification for standard residential openings in Hobe Sound; CGI and CWS units handle larger or higher-DP applications. We’ll show you the product data sheet alongside the price so the comparison is documented, not verbal.

Why Hobe Sound Homeowners Choose Sightline

Sightline Windows & Doors has installed and replaced more than 18,000 windows and doors since 2012 – every one with a written price before work started and a documented photo record when it finished.

The principle is simple. The measured survey we conduct when we visit your home is the same document as your final invoice. The number on page one doesn’t change when the crew shows up. Haven Clause 1 – have it in writing – means the quote and the scope travel together, and if those two things ever diverge, the written document controls. We haven’t had to invoke that clause often, but it’s there in writing because a verbal assurance isn’t evidence.

Sonia Raman leads Sightline’s operations in Hobe Sound, and the standard she applies to every measured survey is the same one that has governed the brand since its founding. Background-checked, uniformed technicians arrive identified by license number before they touch anything – Haven Clause 3, Verified Crews. The photo record captured on every visit is yours to keep – Haven Clause 4, Evidence on every job. And the 365-Day Done Right Promise means that if something isn’t right after the job closes, we come back and make it right. That’s written into the scope, not offered as a courtesy when you complain.
