Impact Window Installation Cost - Written Price Before Anything Is Ordered

How Much Does Impact Window Installation Cost in Hobe Sound?

Impact window installation in Hobe Sound, FL typically runs between $850 and $2,800 per window, all-in, covering the product, labor, and permit fees. A whole-home project on a single-story Hobe Sound property with eight to twelve openings lands most homeowners in the $9,500 to $28,000 range, depending on window size, glass type, and the frame condition the installers find during the measured survey. Written price before any work starts – that’s the only way we operate at Sightline Windows & Doors.

Impact Window Installation Cost Breakdown (2026)

The per-window all-in cost breaks down into three line items: the product itself, the labor to install it, and the permit required by Martin County’s building department. None of those numbers are hidden at Sightline – the measured survey we hand you at the end of the site visit is the same document as the written quote, so you see every line before a tool is touched.

Whole-Home Project Cost Ranges in Hobe Sound

• Small home (6-8 openings, standard sizes): $7,500 – $14,000
• Mid-size home (10-14 openings, mix of sizes): $13,000 – $24,000
• Larger home (16-22 openings, custom or oversize): $22,000 – $42,000
• Waterfront or custom estate (20+ openings, high-performance glass): $35,000 – $65,000+

The widest swing in final cost comes from two things: the condition of the existing frames (something only a measured survey reveals) and the glass specification the homeowner chooses. A PGT WinGuard single-hung in a standard 3/0 x 4/0 size costs substantially less than a CGI Series 350 picture window at 6 feet wide. Both are impact-rated to Florida Building Code – they just serve different openings and different budgets. On the Impact Window Installation in Hobe Sound page, we go deeper into product selection by opening type if you want to compare glass specifications before your site visit.

What Affects Impact Window Installation Pricing in Hobe Sound

Six variables move the number most consistently in this market. The Hobe Sound area has a few local conditions that push pricing differently than, say, a Palm Beach Gardens suburb – the coastal salt air, the concentration of pre-1995 concrete block homes along SE Cove Road and the Gomez Grant corridor, and Martin County’s specific permitting schedule all factor in.

• Window size and configuration: Glazing area drives material cost more than anything else. A standard 3/0 x 5/0 single-hung is priced into the product line’s base tier. A 5-foot-wide picture window in the same CGI Series 350 line costs roughly 2.5x more per unit before labor is added. Hobe Sound homes with large living-room openings facing the Intracoastal frequently require those wider units.
• Frame material and condition of the existing opening: Vinyl-framed pocket installs are the fastest and least disruptive. Aluminum full-frame replacements – common in Hobe Sound homes built in the 1970s and 1980s on Gomez Avenue and Bridge Road – add $150 to $300 per opening in labor because the old frame must be cut out, the rough opening inspected, and a new buck installed before glazing begins.
• Impact rating required by your insurance carrier: Florida’s minimum for Miami-Dade or Broward product approval is a 9-pound large-missile impact test. Many Hobe Sound homeowners in flood zones AE and VE (particularly along the barrier island south of Peck Lake) are required by their insurer to spec products with an additional wind-pressure rating above 140 mph. That spec typically means stepping into the CGI, CWS, or ECO Window Systems tier rather than the entry-level PGT WinGuard line.
• Martin County permitting and inspection timeline: Martin County’s building department processes impact-window permits on a standard track, typically 10 to 21 business days from application to approval. Projects requiring structural calculations (openings wider than 6 feet, or any opening in a V-zone property) may require a signed engineer’s letter, which adds $200 to $500 to the overall scope. Sightline manages the permit application and final inspection scheduling – it’s documented in the written scope the customer receives.
• Glass performance specification (U-factor and SHGC): Standard laminated impact glass has a solar heat gain coefficient around 0.28 to 0.35. Adding a high-performance Low-E coating drops that to 0.19 to 0.24, which matters in Hobe Sound’s west and south elevations during June through September. The upgrade cost per window is modest ($40 to $120), and it often pays back through reduced FPL bills within three to five cooling seasons. We’ll note the SHGC of every product in your written quote so you can compare before choosing.
• Site access and story height: Single-story homes are baseline. Second-floor work adds scaffolding or lift equipment, typically $30 to $80 per upper-floor window in added labor. Hobe Sound waterfront properties with elevated first-floor entries (common in FEMA flood-zone construction built after 2000) sometimes require staging for what looks like a ground-level opening but is actually 10 to 12 feet above grade.

Hobe Sound-Specific Conditions That Move the Number

Hobe Sound sits in the northern section of Martin County, bordered by the Atlantic on the east and the Intracoastal on the west. That geography creates two installation realities that are less common 20 miles south in Stuart or north in Jupiter.

First, the salt air. Homes within a half-mile of the Intracoastal or the beach – think SE Bridge Road, Gomez Avenue between US-1 and the water, and the Jonathan Dickinson State Park edge on the north – see accelerated aluminum frame corrosion. When we run a measured survey on those properties, we frequently find that existing frames are too corroded for a pocket install and need full removal. That pushes per-window labor from the $175-$350 range into the $300-$600 range. A competitor who gives you a pocket-install quote over the phone without a site visit in those neighborhoods is quoting the wrong scope.

Second, the insurance picture. Hobe Sound homeowners – especially on the barrier island and in flood zones – are among the most actively insurance-driven impact-window buyers in Martin County. Citizens Property Insurance Corporation’s ongoing inspection program has flagged a number of Hobe Sound properties for non-compliant openings, which creates a real deadline for some homeowners. We see this regularly in the Olympia neighborhood and along the Jupiter Island corridor. The product specification required to satisfy an insurance carrier inspection is not always the least expensive impact-rated window on the shelf – it’s the one that matches the wind-speed and impact-rating criteria written into the policy or Citizens’ mitigation form.

For homeowners in those situations, the written scope Sightline produces includes the product’s Miami-Dade or Florida Product Approval number and its tested pressure rating, so you can hand that document directly to your insurance adjuster or agent without a separate product certification request.

How to Save on Impact Window Installation

There are four approaches that reliably reduce final cost in the Hobe Sound market without cutting corners on product performance or installation quality.

1. Replace all openings in one project scope

Multi-window projects spread the fixed costs of permitting, labor mobilization, and equipment over more units. A homeowner replacing 14 windows in a single permitted scope will pay less per window than one replacing 4 windows now and 10 windows two years from now – both in product pricing (manufacturers price by order volume) and in permit fees (Martin County charges per-opening fees with a single application cost spread across the project). On a 14-window project, combining the scope typically saves $600 to $1,400 versus two separate pulls.

2. Choose the right product tier for each opening, not the highest for all

Not every opening needs the same product. A bedroom window on an interior wall facing a buffer hedge doesn’t need the same glass specification as a south-facing picture window taking direct afternoon sun. At Sightline, we carry eight manufacturer lines precisely so we can spec PGT WinGuard where it’s sufficient and CGI Series 350 or CWS StormMark where the opening demands it. Homeowners who let a single-line installer quote everything in the high-performance tier often overspend by $2,000 to $5,000 on a mid-size home.

3. Bring any existing written quote to us for a free second opinion

This is a standing offer at Sightline: bring us a competitor’s written estimate and we’ll review it at no charge. We’ll tell you whether the product specified matches your opening requirements, whether the labor scope covers what a measured survey would find, and whether the permit language is complete. Some estimates circulating in Hobe Sound right now are written without a site visit, which means they’re missing frame-condition data. A free second opinion costs you nothing and can save you from an expensive scope gap discovered on installation day.

4. Ask about Florida-specific financing and insurance mitigation credits

Florida’s My Safe Florida Home grant program (funded rounds have varied by year – check current availability with the Florida Division of Emergency Management) has historically offered grants of up to $10,000 for impact-rated window installation on qualifying primary residences. Eligibility requires a wind mitigation inspection and application process, but for Hobe Sound homeowners in the income and property-value thresholds, the savings are real. Separately, your homeowner’s insurance premium reduction from adding impact windows can be substantial – reductions of 15% to 45% on the wind portion of a Florida policy are common, and that payback period shortens the real cost of the project significantly over five years.

What You Get With a Sightline Written Quote

Since 2012, every engagement at Sightline Windows & Doors has started with the same document: the measured survey the customer keeps. Under Haven Clause 1 (Have it in writing), the written price cannot change from that document to the final invoice. Sonia Raman, who leads Sightline, built the process on one principle: the measurement and the quote are the same document, because they should always have been.

Every written scope Sightline issues for a Hobe Sound project includes:

• Line-item pricing for each window, labeled by opening location, product model, and glass specification
• The Florida Product Approval number for each unit (useful for insurance mitigation forms)
• Martin County permit fee estimate, pulled from current fee schedules
• Frame condition notes from the measured survey, with any full-frame removal scope flagged and priced before the quote is signed
• Installation timeline with a scheduled date – Haven Clause 2 (Arrive on schedule)
• Technician identification: background-checked, uniformed, identified by license number before arrival – Haven Clause 3 (Verified Crews)
• A documented photo record of the completed job – Haven Clause 4 (Evidence on every job)
• The 365-Day Done Right Promise in writing – if it’s not done right, we make it right

None of those items are upsells. They’re standard on every job because the Haven Standard requires them. Across the 18,000+ openings Sightline has installed since 2012, the written-price-before-work model has been the process every time, not a promotion.

FAQs – Impact Window Installation Cost in Hobe Sound

How much does impact window installation cost per window in Hobe Sound, FL?

Impact window installation in Hobe Sound costs between $850 and $2,800 per window all-in, covering product, labor, and permit fees. Standard single-hung replacements in average-size openings land in the $850 to $1,400 range; large or custom units with high-performance Low-E glass in coastal specs run $1,600 to $2,800. The measured survey Sightline conducts before any work starts gives you the exact per-window number for your specific home. Call (772) 362-5967 for a free written estimate.

Is it cheaper to replace one window at a time or all windows at once in Hobe Sound?

Replacing all windows in a single permitted scope is consistently cheaper per window than phased replacement. On a 12-window Hobe Sound home, a combined project typically saves $800 to $1,800 versus two separate permits and mobilizations. Martin County’s per-opening permit fees, combined with manufacturer volume pricing and the fixed cost of crew mobilization, all favor doing the full scope at once. That said, the right answer depends on your budget and your insurance carrier’s timeline – Sightline will show you both scenarios in writing so you can decide.

Do I need a permit to install impact windows in Hobe Sound, FL?

Yes, a Martin County building permit is required for every structural glazing replacement in Hobe Sound. The permit fee typically runs $85 to $225 per opening, depending on project size and whether structural calculations are needed. Sightline pulls the permit, schedules the inspection, and closes the permit on your behalf – it’s included in the written scope, not billed separately after the fact. No-permit impact window work is not compliant with Florida Building Code and will not satisfy insurance mitigation requirements.

Can impact windows lower my homeowner’s insurance in Hobe Sound?

Installing impact-rated windows on all openings in a Hobe Sound home typically reduces the wind-coverage portion of a Florida homeowner’s insurance policy by 15% to 45%, depending on your carrier, your home’s construction date, and the product specifications installed. Citizens Property Insurance Corporation and most private carriers require a wind mitigation inspection form (OIR-B1-1802) completed by a licensed inspector to apply the credit. Sightline’s written scope includes the Florida Product Approval number for each window, which that inspector needs to complete the form. The premium reduction often repays a meaningful portion of the installation cost within five to seven years.

What impact window brands does Sightline install in Hobe Sound?

Sightline installs impact windows from PGT, CGI, CWS, ES Windows, and ECO Window Systems in Hobe Sound, specified by what each opening requires. PGT WinGuard is typically specified for standard residential openings where the load requirements are met at that tier. CGI Series 350 and CWS StormMark are specified for larger openings, higher wind-pressure requirements, or barrier-island locations near the Hobe Sound beach. ECO Window Systems is frequently specified for projects where energy performance (SHGC and U-factor) is the primary driver alongside impact rating. The product choice is documented in the written quote before any work starts – not made on installation day. Call (772) 362-5967 for a free estimate with product options named in writing.

How long does impact window installation take in Hobe Sound?

A standard Hobe Sound whole-home replacement of 10 to 14 windows typically takes one to two installation days once the permit is approved and product arrives on site. The Martin County permit process currently runs 10 to 21 business days from application to approval for standard projects. Projects requiring engineer letters (openings wider than 6 feet or V-zone properties) may run 3 to 4 weeks in the permitting phase. Lead times on PGT and CGI product lines currently run 3 to 6 weeks from order confirmation in the Hobe Sound market as of 2026. The scheduled installation date is written into your scope document – Haven Clause 2 (Arrive on schedule) means it’s a commitment, not an estimate.
