Single & Double Hung Windows in Hobe Sound, FL

Single & Double Hung Windows in Hobe Sound, FL

Single and double hung windows are the most common window type in Hobe Sound homes, and they’re also the most frequently replaced – partly because older aluminum single-panes age poorly in the salt air off the St. Lucie Inlet, and partly because Florida’s energy codes have moved well past what most 1990s and early 2000s construction originally specified. A single hung window has a fixed upper sash and a lower sash that slides up to open; a double hung has two operable sashes, which makes cleaning easier and gives you more ventilation options without a ladder on the second floor. At Sightline Windows & Doors Hobe Sound, every Window Installation starts with a measured survey – the same document that becomes your written price – so there’s no gap between what we find and what you’re quoted.

If you’re weighing options or trying to understand what a full window replacement involves before calling anyone, our Window Installation in Hobe Sound page covers scope, timeline, and product categories across all opening types. For single and double hung work specifically, call us at (772) 362-5967 – a live person picks up, every call, every day.

When You Need Single & Double Hung Windows

Hobe Sound sits in a stretch of Martin County where the humidity is persistent, the wind exposure is real, and any window that wasn’t built for the Florida climate will show it within a decade. If you’re looking for Window Installation Near Me in Hobe Sound, FL, here’s what we see on-site regularly: Here’s what we see on-site regularly:

• Sashes that stick or won’t lock flush. In Hobe Sound neighborhoods like Lost Lake and the older sections near Bridge Road, wood-frame and aluminum single hungs from the 1980s and 90s have often swollen, warped, or corroded to the point where the sash no longer seats correctly in the frame. A window that won’t latch is a window that doesn’t meet current hurricane-preparedness standards.
• Visible condensation between panes or on the interior glass. When the seal on an insulated glass unit fails, you get fogging that won’t wipe off. This is the glass telling you the thermal barrier is gone – and with it, any U-factor or SHGC performance you paid for when the window was new.
• High electric bills that don’t match your usage. A single-pane window in a Hobe Sound home that runs air conditioning nine months of the year is transferring heat at roughly four times the rate of a modern low-e double-pane unit. The numbers show up on the FPL bill before they show up as comfort complaints.
• Impact rating gaps ahead of a re-roof or insurance review. Martin County insurers have been asking for documented product approvals on windows when policies renew or homes go through underwriting. If your windows carry no impact rating and no Florida Product Approval number, that conversation becomes expensive.
• Worn or broken balance systems. Double hung windows rely on a balance mechanism – spring-loaded or block-and-tackle – inside each jamb channel. When it fails, the sash drops or won’t stay open. This is repairable in some cases, but on windows older than fifteen years the hardware is often discontinued and full replacement is the more cost-accurate path.
• Renovation or resale work requiring consistent sight lines. Mismatched window profiles between original windows and later additions are common in the Jupiter Island Road and Gomez Road corridors. Replacing all single and double hungs in one measured survey keeps sightlines – the visible frame depth and grid alignment – uniform across the elevation.

Our Single & Double Hung Windows Process

Every step below is governed by the Haven Standard, the operating framework that has covered every one of the 18,000+ openings Sightline has installed since 2012. Nothing in this process is optional or offered as an upgrade.

1. Measured Survey – the document you keep. A background-checked, uniformed technician comes to your home and measures every opening: rough opening width and height, frame depth, existing sill angle, and any structural considerations. You receive a copy of this survey. Under Haven Clause 1 (Have it in writing), the written quote cannot deviate from what this document shows – the measurement and the price are the same record.
2. Product specification by opening, not by inventory. Based on the survey, we specify the right product for each opening: single hung or double hung, impact-rated or non-impact, frame material, glass package (U-factor, SHGC, and any low-e coating), and color profile. In Hobe Sound, most homes within a mile of the Intracoastal get specified for impact-rated units; we draw from PGT and CGI for impact work, and CWS for energy-efficient non-impact applications where code and exposure allow. The specification is written into your quote before any commitment is made.
3. Written price before any work starts – always. Haven Clause 1 is the whole point. The written price you receive before the first tool is lifted is the price on the final invoice. There is no change-order language buried in the contract for standard single and double hung replacement. If the survey turns up something structural – a rotted rough opening or a lintel issue – we document it in writing and price it separately before proceeding.
4. Installation by verified, licensed crews. Haven Clause 3 (Verified Crews) means the technician who arrives has been background-checked and is identified by license number before the appointment. For single and double hung replacement, the standard scope is: removal of the existing unit, inspection of the rough opening and sill for moisture or rot, installation of the new frame with fasteners to spec, application of flashing tape and sealant at the perimeter, and setting and adjustment of the sash balance system. Florida’s glazing installation standards require proper fastener patterns for wind load compliance; we document those in the site record.
5. Documented photo record on every visit. Haven Clause 4 (Evidence on every job) means before-and-after photos of each opening are part of the file. This isn’t a premium option – it’s standard. For homeowners dealing with insurance documentation or HOA approval in communities like Retreat at Hobe Sound or Sea Pines, this record has practical value beyond the job itself.
6. 365-Day Done Right Promise. If anything about the installation – hardware function, weatherstrip fit, sash operation, or seal integrity – is not right within the first year, we make it right. This is written into the Haven Standard on every job, not offered as a courtesy when something goes wrong.

Single & Double Hung Windows Pricing in Hobe Sound

Single and double hung window replacement in Hobe Sound typically runs between $420 and $1,150 per window installed, depending on size, glass package, and whether an impact rating is required. That range covers the full scope: product, labor, removal of the existing unit, and the photo-documented close-out. It does not include structural repairs to a damaged rough opening, which are quoted separately if the survey finds them.

What moves the number within those ranges: glass package (standard double-pane vs. low-e vs. impact laminate), frame color (standard white vs. bronze vs. custom), opening size, floor (ground level vs. second story requiring additional staging), and the number of windows on a single visit – multi-window jobs share mobilization cost, which brings the per-unit price down.

Hobe Sound’s coastal exposure also affects specification. Homes east of US-1, particularly in the Gomez neighborhood and the lots backing up to the Intracoastal, are typically specified for impact-rated product as a baseline. That’s not Sightline’s preference – it reflects what Martin County’s wind zone maps and insurance underwriters require in those locations. The survey document we give you names the product and the reason for the specification.

There is no charge for the estimate. Call (772) 362-5967 and we’ll schedule the measured survey at your convenience. The written price you receive after that visit is the price – Haven Clause 1, documented before anyone picks up a tool.

FAQs – Single & Double Hung Windows in Hobe Sound

What’s the difference between single hung and double hung windows, and which is better for Hobe Sound?

A single hung window has one operable sash – the bottom one moves up, the top stays fixed. A double hung has two operable sashes, both of which tilt in for cleaning and allow you to open from the top or bottom independently. For Hobe Sound homes with second-floor windows or enclosed lanais where exterior access is limited, Awning & Hopper Windows or double hung is usually the more functional choice: you can clean both sashes from inside without climbing. For ground-floor openings with easy exterior access, single hung is a serviceable option that costs somewhat less per unit. Neither type outperforms the other on impact resistance or energy efficiency – those are functions of the glass package and frame spec, not the sash configuration.

How much do single and double hung windows cost in Hobe Sound?

Installed cost in Hobe Sound runs approximately $420 to $720 per window for non-impact single and double hung units, and $620 to $1,000 for impact-rated units in standard sizes. Oversized openings and custom colors push that higher. The most reliable number is the one on your written survey – call (772) 362-5967 for a no-cost measured estimate and you’ll have a documented price before any commitment is made.

Are impact-rated windows required in Hobe Sound?

Martin County’s building code requires windows in new construction and full replacements to meet the wind load specifications for the installation’s wind zone. Hobe Sound falls in a high-wind zone, and most of the area east of US-1 requires impact-rated product or an approved alternative (such as impact shutters combined with non-impact glazing). The building permit application triggers a product approval review, and your product must carry a valid Florida Product Approval number. Sightline’s measured survey documents the applicable zone for your address and specifies product accordingly – you don’t have to interpret the code yourself. Impact-rated single and double hung units from PGT and CGI both carry the required Florida Product Approvals for Martin County installations.

How long does a single or double hung window replacement take in Hobe Sound?

A standard single or double hung replacement – one window, existing frame in sound condition – takes roughly two to three hours on-site including removal, installation, sealing, and photo documentation. A whole-house replacement of eight to twelve windows typically runs one full day. Lead time from signed written agreement to installation date currently ranges from two to four weeks, depending on product specification and order volume. If the survey finds a custom size or a non-stock frame color, add one to two weeks for product lead. You’ll know the timeline in writing before you sign anything.
