How Much Does New Window Installation Cost in Lighthouse Point?

New window installation in Lighthouse Point, FL typically runs $380 to $1,200 per window installed, including labor, with most single-family homes in the area landing between $6,500 and $18,000 for a full-house project. Impact-rated glazing – required by Broward County code for new construction and major renovations – accounts for the largest share of that cost, and saltwater proximity along the Intracoastal adds product-specification requirements that push Lighthouse Point pricing above the national average by roughly 15 to 20 percent.

New Window Installation Cost Breakdown (2026)

Every written price Sightline produces starts from the same measured survey – the document you keep, and the one our final invoice must match exactly under Haven Clause 1. The ranges below reflect actual project pricing in the Lighthouse Point market as of early 2026, drawn from our work on homes throughout this zip code and the surrounding barrier-island corridor.

What moves the number up

The biggest single driver in Lighthouse Point is impact glass specification. Florida Building Code Section 1609 governs windborne debris regions, and Broward County falls squarely inside the High-Velocity Hurricane Zone (HVHZ) designation – which means laminated impact glass is not optional on any permitted opening. A standard double-pane, non-impact window that costs $180 per unit in a Midwest market costs $380 or more here simply because the glass assembly must meet Miami-Dade Notice of Acceptance (NOA) standards.

Secondary drivers: home age and construction type. A 1970s CBS (concrete block structure) home in the neighborhood west of Sample Road will often need buck framing when the original opening was sized for jalousie or aluminum single-pane windows. That adds $60 to $140 per opening in labor. Waterfront lots east of the Intracoastal carry a marine-exposure requirement – products need a G-90 or better corrosion rating on all hardware, and certain CGI and PGT lines are specified specifically for that environment.

Third: glass area. Lighthouse Point’s Mediterranean and ranch-style homes frequently feature large fixed picture windows and full-wall sliders that face the water or a pool deck. A 72-inch-by-48-inch fixed impact window carries significantly more glass cost than a standard 30-by-48 double-hung, and the price scales closer to linearly with area than most homeowners expect.

What keeps the number down

Retrofit installation – replacing an existing window in an existing opening without structural modification – costs 20 to 35 percent less than a full new-construction installation because no framing or buck work is required. If your Lighthouse Point home already has aluminum impact frames from a prior upgrade and you are replacing only the sash or the glass unit, costs can drop further. Multi-window projects also carry volume efficiency: mobilizing a crew for eight windows costs less per unit than mobilizing for two, and that savings is passed through in the written quote.

What Affects New Window Installation Pricing in Lighthouse Point

• Impact-rated glass specification (HVHZ compliance): Lighthouse Point sits inside Broward County’s High-Velocity Hurricane Zone. Every permitted window must carry a Miami-Dade NOA, and that glass assembly – laminated, impact-rated, minimum 3/16-inch nominal thickness on most residential specs – adds $80 to $200 per window over a comparable non-impact unit. There is no legal workaround for new installation on a permitted project.
• Proximity to saltwater: Homes within roughly a half-mile of the Intracoastal Waterway – which includes most of Lighthouse Point east of US-1 – face accelerated hardware corrosion. Product selection shifts toward marine-grade hardware and corrosion-rated frames. CGI’s Guardian line and PGT’s WinGuard are the two most-specified products in this corridor for that reason. Marine-spec hardware adds $30 to $80 per window at the product level.
• Window type and operability: A fixed picture window costs less to install than a casement of the same size because there are no moving parts to align and no hardware to calibrate. Bay and bow units require a site survey that accounts for structural header load – that structural review adds cost regardless of who does the job. Custom and geometric openings (arched transoms are common in Lighthouse Point’s Mediterranean-influenced streetscape) are priced individually because no standard manufacturing run exists for them.
• Home construction era and opening condition: Lighthouse Point’s housing stock spans from 1950s post-war concrete block to 2010s poured-concrete new construction. Older homes built before Florida’s current code cycles often have openings sized for jalousie or single-pane aluminum windows that do not match any modern impact-rated unit directly. Custom sizing, buck framing, or rough-opening modification adds labor and, in some cases, drywall or stucco repair that needs to be documented in the measured survey before a price is set.
• Glass area and unit count: Cost scales with glass area more than with window count. A home with six large picture windows facing the water will carry a higher project total than a home with twelve standard double-hungs, even if the unit count is lower. On multi-unit projects, per-window costs decrease because mobilization and permit overhead are spread across more openings.
• Product line and performance tier: Sightline specifies from eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – and the price difference between a base-tier impact unit and a high-performance, low-U-factor unit from the same manufacturer can be $80 to $200 per window. U-factor (a window’s resistance to heat transfer) and SHGC (solar heat gain coefficient, which controls how much radiant heat enters through the glass) matter in South Florida’s climate because they directly affect your air conditioning load year-round. A window with a U-factor of 0.30 and an SHGC of 0.22 will perform measurably better in Lighthouse Point’s climate than a lower-cost unit at U-0.40 and SHGC 0.32, and that performance difference is recoverable in utility costs over a 7-to-10-year horizon.

A note on permits in Lighthouse Point

Broward County requires a permit for any new window installation – not just full new construction. Replacement-in-kind on a like-for-like opening still requires a permit if the product is changing (which it almost always is when going from single-pane to impact). Sightline pulls permits as part of the project scope; the permit fee is named in the written quote, not added at the end. Unpermitted impact window installations in Lighthouse Point have surfaced during home sales as title issues, and we’ve done second-opinion surveys on competitor quotes that omitted permit costs entirely – a $150 line item that becomes a $3,000 problem at closing.

How to Save on New Window Installation in Lighthouse Point

Get the full scope in writing before comparing quotes

The most common source of sticker shock in Lighthouse Point window projects isn’t the window itself – it’s the difference between what one contractor quoted and what another contractor scoped. If one quote includes permit fees, stucco repair, and haul-away and another doesn’t, the lower number isn’t lower. Ask every contractor for an itemized written quote before you compare line one. Under Haven Clause 1, every Sightline quote is the measured survey – there is no separate document, and the final invoice cannot exceed the written price.

Replace all windows in one project if you can

Mobilization, permitting, and crew scheduling are largely fixed costs per project, not per window. Running a crew to Lighthouse Point for two windows costs nearly as much as running that same crew for ten. If your budget allows, combining all your openings into a single permitted project typically reduces per-window costs by 12 to 20 percent compared to phasing the work across multiple visits.

Specify by performance need, not by brand recognition

PGT and CGI are the most-recognized impact window brands in South Florida, and they earn that recognition – but they aren’t always the right specification for every opening. On a north-facing interior bedroom window in a Lighthouse Point CBS home, an ES Windows or ECO Window Systems unit at a lower price point may meet every applicable code requirement and performance threshold without the brand premium. Sightline’s measured survey identifies which product tier each opening actually needs, not which product line carries the highest margin.

Take advantage of the free second opinion

If you have a written estimate from another contractor, bring it to us. We review competitor quotes at no charge – not to undercut indiscriminately, but to identify whether the scope is complete, whether the products are correctly specified for HVHZ, and whether the pricing is consistent with the current Lighthouse Point market. Call (754) 600-8907 to schedule a free second-opinion survey.

Check for Florida energy efficiency programs

Florida’s state-level energy efficiency programs and select utility rebates occasionally apply to high-performance glazing that meets specific U-factor and SHGC thresholds. Eligibility changes annually and varies by utility territory. We don’t promise rebates on any written quote because we can’t guarantee program availability – but we can identify which products on your scope meet the technical thresholds so you can apply independently. FPL and Broward County have both run residential efficiency incentive programs in recent years that covered a portion of impact window upgrade costs.

Ask about the documented photo record

This isn’t a savings tip in the traditional sense, but it protects your investment: every Sightline installation in Lighthouse Point leaves a documented photo record of the opening condition before, during, and after glazing. That record is evidence of what was done and how, and it supports any warranty claim under the 365-Day Done Right Promise without dispute. It also functions as documentation during a home sale – buyers in Lighthouse Point increasingly request installation records for impact windows as part of due diligence.

For an exact written price on your Lighthouse Point home, call (754) 600-8907. Estimates are free, written, and based on a measured survey – not a ballpark figure over the phone.

FAQs: New Window Installation Cost in Lighthouse Point

How much does it cost to install one impact window in Lighthouse Point?

A single impact-rated window in Lighthouse Point costs $380 to $780 installed for a standard double-hung or sliding unit, with casements and larger fixed windows running higher. That range includes labor, but single-window projects also carry the full weight of mobilization and permitting costs that don’t scale down proportionally, so the effective per-window cost on a one-window project is usually at the top of that range. For an exact number on your specific opening, call (754) 600-8907 – estimates are free and written before any work starts.

Is impact glass required for new window installation in Lighthouse Point?

Yes. Lighthouse Point falls within Broward County’s High-Velocity Hurricane Zone designation under the Florida Building Code. Any permitted new window installation must use impact-rated glazing that carries a Miami-Dade Notice of Acceptance, or the installation must include approved shutters as an alternative. For new installations – as opposed to shuttered existing windows – impact glass is the standard specification on virtually every residential project we complete in Lighthouse Point. There is no permitted path around this requirement on a new installation.

How long does new window installation take in Lighthouse Point?

Most full-house projects in Lighthouse Point take one to three installation days once materials are on-site. The longer lead time is usually the manufacturing and delivery window: impact-rated products from PGT, CGI, and CWS typically carry a 4-to-8-week lead after the measured survey and product order are finalized. Permitting in Broward County currently runs 2 to 4 weeks for residential window projects. Plan for a total timeline of 8 to 14 weeks from signed scope to completed installation on a typical Lighthouse Point home.

What is the difference between replacement windows and new construction windows in Lighthouse Point?

Replacement windows (also called retrofit or insert windows) are sized to fit into an existing frame without modifying the rough opening or the surrounding wall. New construction windows require the full rough opening and use a nailing fin that attaches to the structure directly. In Lighthouse Point, retrofit installation typically costs 20 to 30 percent less per opening than new construction installation because no structural modification is involved. The trade-off is that retrofit units have a slightly smaller sightline – the actual glass area visible – because the new frame sits inside the old one. New construction installation gives you the full opening dimension. Our measured survey identifies which approach each opening supports and documents both options in the written scope if you want to compare.

Can I get a written price for my Lighthouse Point windows without committing to the project?

Yes. The measured survey and the written quote are the same document, and you keep a copy regardless of whether you sign. There is no obligation attached to the estimate. Under Haven Clause 1, Sightline’s written price is fixed – it’s not a starting-point figure that increases after you’ve cleared your schedule. If you have a competitor’s quote and want a second opinion, we review those at no charge as well. Call (754) 600-8907 to schedule.

How much does a full window replacement cost for a typical Lighthouse Point home?

A typical Lighthouse Point single-family home with 8 to 14 windows runs $6,500 to $18,000 for a complete installation, including impact-rated glazing, labor, and permits. Homes east of Federal Highway and along the Intracoastal tend to sit at the higher end of that range because of marine-exposure hardware requirements and the prevalence of large fixed or custom openings in waterfront properties. A 10-window project using mid-tier PGT WinGuard or ES Windows product in a standard CBS home typically lands between $9,000 and $13,500 installed. For a number tied to your specific home, the measured survey is the only accurate source – call (754) 600-8907 for a free, written estimate.

Why Lighthouse Point Homeowners Specify Product Before Price

There’s a pattern we see repeatedly in Lighthouse Point: a homeowner gets three quotes, picks the middle one, and six months later calls us to ask why their new impact windows are showing corrosion on the hardware or why the installer won’t respond to a warranty call. The quotes looked similar on paper. But the product specifications weren’t the same, the hardware ratings weren’t documented, and the warranty was verbal.

The Lighthouse Point market has specific requirements that don’t apply 50 miles inland – HVHZ glass specification, marine-grade hardware ratings for waterfront and near-waterfront lots, and Broward County permit compliance. A quote that doesn’t document those specifications isn’t comparable to one that does, even if the dollar amounts are close.

Sightline’s measured survey names the manufacturer, the product line, the NOA number, the U-factor, and the SHGC for every window on your scope. That document is what you use to compare – not a per-window ballpark. Every one of the 18,000+ openings we’ve installed since 2012 started with that written document, and every one of those projects is covered by the 365-Day Done Right Promise. If something isn’t right, we make it right – that’s written into the Haven Standard, not offered at our discretion.

Our work in Lighthouse Point specifically covers the full range of residential installation: standard double-hungs and sliders in the neighborhood’s post-war CBS homes, large fixed and custom geometric units in waterfront properties along the eastern corridors, and full-house impact upgrade projects on homes where the original aluminum windows have reached the end of their service life. The new window installation service page for Lighthouse Point covers the full project scope in more detail if you want to review what the installation process looks like start to finish.
