AfterSingle & Double Hung Windows in North Palm Beach, FL
Single and double hung windows are the most common window type in North Palm Beach homes, and replacing them through our Window Installation service is one of the most straightforward investments you can make in comfort, energy efficiency, and storm protection. A single hung window has a fixed upper sash and a lower sash that slides up; a double hung has two operable sashes, which makes cleaning easier and gives you more control over ventilation. At Sightline Windows & Doors North Palm Beach, every replacement starts with a written price before a single tool comes out of the truck – that’s Haven Clause 1, and it applies to every job we touch.
If you’re comparing quotes or trying to understand what a hung window replacement actually involves here in North Palm Beach, call us at (561) 475-1246 – a live person picks up, not a voicemail. We’re part of our broader Window Installation in North Palm Beach service, and single and double hung windows make up a significant portion of what we install year over year.
Since 2012, we’ve documented more than 18,000 window and door openings across South Florida under the Haven Standard. Sonia Raman leads every engagement with the same measured-survey-first discipline: the document you receive after your site visit is the same document that becomes your invoice. No adjustments later. No surprises at the end.
When You Need Single & Double Hung Windows
Not every window problem is obvious from the inside. Some show up as a utility bill that climbs through June and July; others are quieter – a draft you only notice when the AC shuts off. Here are the conditions we most commonly diagnose in North Palm Beach homes during a measured survey:
- Windows that won’t stay open or won’t seal shut. Balance springs wear out over time, and in a climate with North Palm Beach’s humidity, wood and vinyl frames absorb moisture and warp. A sash that drops on its own or won’t latch creates both a ventilation problem and an opening in your building envelope.
- Visible condensation between the panes. This is a failed insulated glass unit (IGU) – the argon or krypton fill has escaped and the seal is gone. Repairing a seal is rarely durable; replacing the window is the documented fix. We see this frequently in homes built between 1990 and 2008 in the Plat 7 and Plat 9 areas of North Palm Beach.
- Single-pane glass still in place. If your home hasn’t been updated since before 2005, there’s a reasonable chance some of your hung windows are still single pane. Those windows contribute almost nothing to your home’s thermal resistance (U-factor) and provide no meaningful impact protection.
- Frame deterioration at the corners or sill. North Palm Beach sits on a narrow barrier island with salt air coming off the Intracoastal on one side and the Atlantic on the other. Aluminum frames oxidize; wood frames rot at the sill; vinyl frames degrade at mitered corners. When the frame goes, the flashing around it often goes with it.
- Noise from US-1 or PGA Boulevard traffic. A properly glazed double hung with laminated impact glass significantly reduces exterior noise. If you’re within half a mile of either corridor, the acoustic benefit of a quality replacement is measurable, not theoretical.
- Failing to meet current Florida Building Code wind-load requirements. Palm Beach County enforces impact ratings. If you’re replacing windows under a permit, the new units must meet the county’s wind-load and missile-impact standards. We pull the permit, document the specs, and leave you with the inspection record.
Our Single & Double Hung Windows Process
Every job follows the same documented sequence. Nothing is skipped to save time, because skipping a step is how you end up with a callback – and we’d rather be right once than return twice.
- Measured Survey. We arrive at the scheduled window, not a four-hour arrival range. A Sightline technician takes rough opening measurements, checks the frame condition, reads the existing sightline depth, notes the substrate (wood buck, CBS block, or metal stud), and photographs the existing unit. You receive this document. It does not change.
- Written Scope and Price – Before Anything Else. The measured survey becomes the written price on the spot. Product line, glass specification (impact-rated, laminated, Low-E coating, SHGC rating), frame color, and labor are each itemized. Haven Clause 1: Have it in writing. The number on that page is the number on your invoice.
- Product Selection and Lead Time. We draw from eight manufacturer lines. For single and double hung applications in North Palm Beach, we most commonly specify units from CWS, ES Windows, or ECO Window Systems depending on the opening requirements, your budget tier, and whether impact-rated glazing is needed. We’ll walk you through the trade-offs in plain terms: U-factor, SHGC, impact rating, and frame profile – each explained in one plain sentence, not a brochure.
- Permit Pull. Palm Beach County requires a permit for window replacements. We handle the application, provide the product approvals (Florida Product Approval numbers travel with every unit we install), and schedule the inspection. You should never have to call the building department yourself.
- Installation. A background-checked, uniformed Sightline crew arrives – Haven Clause 3 (Verified Crews). The old window comes out, the rough opening is inspected and corrected if needed, flashing tape is applied to the sill before the new frame goes in, the unit is set plumb and square, fastened per the manufacturer’s installation instruction, and caulked with a product rated for South Florida UV exposure. Interior trim is reinstalled or replaced. The site is left clean.
- Photo Record and 365-Day Done Right Promise. Before the crew leaves, they document the finished installation with photographs – Haven Clause 4 (Evidence on every job). You get those images. Every installation is covered by the 365-Day Done Right Promise: if it’s not right, we make it right. That’s written into the Haven Standard, not offered verbally.

AfterSingle & Double Hung Windows Pricing in North Palm Beach
Single and double hung window replacement in North Palm Beach typically runs between $420 and $1,100 per opening, fully installed with permit. That range covers the majority of standard residential openings. Custom sizing, 3-Panel Sliding (3-Lite Roller) Windows, architectural shapes integrated into a hung configuration, or high-performance glazing specifications push that ceiling higher. Below is a more detailed breakdown by common scenario:
| Scenario | Installed Price Range (per window) |
|---|---|
| Standard single hung, vinyl frame, impact-rated laminated glass, up to 36″ x 60″ | $420 – $620 |
| Standard double hung, vinyl or aluminum frame, impact-rated Low-E glass, up to 36″ x 60″ | $520 – $780 |
| Oversized double hung (36″ x 72″ and above), impact-rated, aluminum frame | $740 – $1,100 |
| Frame replacement or repair included (deteriorated wood buck or CBS repoint) | Add $80 – $250 per opening |
| Multi-window project discount (6+ openings same address, same visit) | Documented in writing on the estimate |
Three variables move the number more than anything else: glass specification, frame condition, and opening size. Impact-rated laminated glass with a Low-E coating costs more than standard insulated glass, but in North Palm Beach it’s almost always the right specification – both for Florida Building Code compliance and for actual storm performance. A window that fails code isn’t a window; it’s a liability.
Frame condition matters because we don’t quote a number and then add surprises when we open the wall. If there’s rot at the sill or a CBS block that needs repointing, that cost is identified at the measured survey and written into the scope before anything starts. That’s not a policy we offer selectively; it’s how every Sightline quote works.
We also offer a Free Second Opinion on any written estimate. If another installer has handed you a number, bring it to us. We’ll review it at no charge and tell you specifically what it does and doesn’t include.
For an exact figure on your specific openings, call (561) 475-1246. Estimates are free, and the price we give you on the phone becomes a written document before anyone arrives at your home.
FAQs – Single & Double Hung Windows
What’s the difference between a single hung and a double hung window, and which one is right for my North Palm Beach home?
A single hung window has a fixed top sash and a movable bottom sash; a double hung has both sashes operable. For most North Palm Beach homes, double hung units are the practical choice, though we also install Awning & Hopper Windows where the tilt-in cleaning feature on the upper sash matters in a salt-air environment where glass and frames need regular washing. Single hung units cost slightly less – typically $60 to $120 less per opening – and make sense in locations where the exterior is easily accessible for cleaning or where budget is a primary constraint. Your measured survey will flag which configuration makes sense for each opening. Call (561) 475-1246 to schedule that survey at no cost.
Do hung window replacements in North Palm Beach require a permit?
Yes. Palm Beach County requires a permit for any window replacement, and the replacement unit must carry a current Florida Product Approval number that matches the county’s wind-load zone for your address. Sightline pulls the permit, supplies the product approval documentation, and schedules the county inspection. You receive a copy of the inspection record. If a contractor tells you a permit isn’t required for a “like-for-like” swap, that’s not accurate for Palm Beach County residential work – and an unpermitted installation creates a title problem if you sell.
How long does a single or double hung window replacement take in North Palm Beach?
Most residential openings take 45 to 90 minutes per window for the physical installation, not counting permit lead time. Palm Beach County building permits for window work typically take 5 to 15 business days to process, depending on current department volume. We schedule your installation date after permit issuance, not before. A five-window project in a single day is a standard schedule for us; we don’t stage partial installations and leave openings exposed overnight.
Is it worth replacing single hung windows with double hung, or should I just repair the existing ones?
Repair makes financial sense only when the frame is structurally sound and the glass unit is intact. A broken balance spring on a relatively new vinyl frame can be corrected for $80 to $150 per sash. But if the frame is deteriorated, the glass seal has failed, or the unit is single-pane, repair costs approach or exceed replacement costs within a few years. In North Palm Beach’s salt-air climate, a frame that’s showing corrosion at the corners rarely stabilizes – it continues to degrade. Our measured survey will give you a documented condition reading on each opening so you’re making that call with actual data, not a guess. Call us at (561) 475-1246 for a no-cost assessment.
