Fast, Reliable Impact Windows & Doors Across North Palm Beach
Window Replacement in North Palm Beach typically runs $1,200-$3,800 per opening for a complete system including frame, impact-rated glazing, and installation, with most canal-front CBS ranch homes needing 12-18 units to reach full envelope compliance. We dispatch crews to North Palm Beach from our South Florida scheduling office, and every job starts with a measured survey the homeowner keeps - the same document that becomes the written quote, unchanged.
North Palm Beach was built out almost entirely between the mid-1950s and mid-1970s as a master-planned community, leaving a dense inventory of CBS ranch homes still fitted with original jalousie and single-pane aluminum windows directly exposed to salt air off the Intracoastal Waterway. Because jalousie windows cannot be made impact-rated, any homeowner seeking current Palm Beach County wind-load compliance faces mandatory full-unit replacement - making this village a near-constant market for complete impact window and door system upgrades rather than repairs or retrofits. Our Impact Windows & Doors team has measured, specified, and installed impact-rated systems across the village’s original General Development Corporation neighborhoods, from Lighthouse Drive canal-front ranches to the interior streets near North Palm Beach Country Club.

Our Impact Windows & Doors Services in North Palm Beach

Impact-Resistant Windows
Impact-resistant windows in North Palm Beach must meet HVHZ (High Velocity Hurricane Zone) ratings under the Florida Building Code, with laminated glass interlayers that hold the pane intact under wind-borne debris impact. For the village’s 1955-1975 CBS ranch stock, this means full-frame replacement: the original jalousie or single-pane aluminum units cannot be retrofitted to impact standards. A typical impact-resistant window installation in North Palm Beach runs $1,200-$2,400 per opening for standard sizes, with custom or geometric units ranging higher. We specify from CWS, ES Windows, and ECO Window Systems lines, matched to the opening’s exposure rating and your wind-mitigation documentation needs.

Hurricane Impact Windows
Hurricane impact windows for North Palm Beach homes carry design pressure ratings of +50/-60 psf or higher, required by the village’s coastal wind-speed zone. The Intracoastal exposure on canal-front properties off Lighthouse Drive and Prosperity Farms Road often pushes specifications to the upper end of the product range. We install PGT service in North Palm Beach and CGI hurricane-rated systems with documented DP ratings, and every unit leaves our warehouse with the Miami-Dade or Florida Product Approval number visible for inspector verification. Hurricane impact window replacement in North Palm Beach typically costs $1,400-$3,200 per opening, depending on size, exposure, and whether the original rough opening requires reframing.

Single Hung Impact Windows
Single hung impact windows - fixed upper sash, operable lower sash - are the workhorse replacement for original aluminum units in North Palm Beach’s smaller bedrooms and secondary spaces. The format matches the sightlines of 1960s ranch architecture without the operational complexity of double hung. In North Palm Beach’s salt-air environment, we specify vinyl or thermally broken aluminum frames with stainless steel hardware, not the original mill-finish aluminum that corrodes at the jamb in ten to fifteen years. Single hung impact windows in this market run $1,100-$2,100 installed, with ES Windows and Mr-Glass lines offering strong performance at mid-tier pricing.

Double Hung Impact Windows
Double hung impact windows, with both sashes operable, suit North Palm Beach homes where cross-ventilation matters - particularly interior-facing rooms without direct Intracoastal breeze. The tilt-in feature also matters for second-story maintenance on split-level ranches near North Palm Beach Country Club. These units cost more: $1,600-$3,000 per opening in the North Palm Beach market, reflecting the dual balance system and additional hardware. We document the U-factor and SHGC on every specification sheet, critical for homeowners pursuing Florida Statute 627.0629 wind-mitigation insurance credits.

Wind Mitigation & HVHZ Code Compliance
Wind mitigation documentation is not an afterthought in North Palm Beach - it’s often the reason for the project. Our measured survey includes the opening dimensions, exposure class, and product specification needed for the uniform mitigation verification form. We were replacing original jalousie windows with PGT impact-rated units on a canal-front ranch off Lighthouse Drive, and pulling the first sash revealed corroded steel lintels and no sill pan flashing anywhere along the opening. Our tech called the homeowner, we wrote a change order against the contract’s inspection allowance for lintel replacement and jamb repair, and the homeowner approved it in writing before we set the first new frame. The finished system passed the village inspection with laminated glass interlayer and low-E glass throughout, and the homeowner used the completed upgrade to file for the Florida Statute 627.0629 wind mitigation credit.

Common Impact Windows & Doors Problems We See in North Palm Beach Homes

- Corroded aluminum jambs and sills beyond repair. Salt-air exposure off the Intracoastal Waterway has eaten original aluminum frames to the point where the village inspector flags any attempt at like-for-like replacement. The rough opening must be rebuilt with impact-rated framing and proper sill pan flashing.
- Missing secondary waterproofing behind original frames. General Development Corporation builders often set window headers without house wrap or proper flashing. Pull the frame on a 1960s CBS ranch near Prosperity Farms Road, and you’ll find water staining and soft block the homeowner never knew existed. The permit triggers the repair, not the window itself.
- Original electrical run tight against rough openings. 1950s-70s wiring frequently lacks modern code-required protection once a full impact unit exposes the cavity. We find this on roughly one in three North Palm Beach ranch jobs, and it adds a line item the homeowner didn’t budget for.
- Jalousie windows that cannot be made impact-compliant. The slatted design has no impact-rated equivalent. Any jalousie replacement in North Palm Beach is a full-system upgrade by definition, with the village building department enforcing this strictly.
Pricing for Impact Windows & Doors in North Palm Beach, FL
Impact window and door pricing in North Palm Beach reflects three variables: the product specification, the condition of the existing opening, and the village’s permit-triggered code upgrades. Here’s what we see in the current market:
| Service | Typical Range (North Palm Beach) |
|---|---|
| Single hung impact window, standard size | $1,100 - $2,100 |
| Double hung impact window, standard size | $1,600 - $3,000 |
| Horizontal roller/slider impact window | $1,400 - $2,800 |
| Impact-rated sliding glass door (6-8 ft) | $2,800 - $5,500 |
| Impact entry door with sidelite | $3,200 - $6,800 |
| Lintel replacement / rough opening repair (per opening) | $400 - $1,200 |
| Electrical code upgrade at opening (when required) | $200 - $600 |
These ranges include product, installation, and standard trim. They do not include permit fees, which vary by project scope and are paid directly to the village. Every Sightline quote includes an inspection allowance - typically 8-12% of the base contract - for conditions we cannot see until the original frame comes out. If we find nothing, you pay nothing from that allowance. If we find corroded lintels or missing flashing, the change order is priced and approved in writing before we proceed.

FAQs - Impact Windows & Doors in North Palm Beach

Jalousie windows have no impact-rated equivalent in the building code, and North Palm Beach’s separate building department enforces full impact compliance on every replacement. The village inspector will flag any attempt to install non-impact units in a jalousie rough opening, forcing removal and re-installation at greater cost. Call (561) 475-1246 and we’ll specify the correct impact-rated system from the start.
Yes. North Palm Beach requires a permit even for like-for-like window replacements, and the inspector will verify impact rating, installation method, and flashing detail. This is stricter than unincorporated Palm Beach County and triggers the code upgrades we build into every contract. Call (561) 475-1246 to schedule a survey that includes permit handling.
Rusted steel lintels, rotted jalousie sills, no sill pan flashing, and frequently original wiring without modern protection. We price an inspection allowance into every contract to cover these findings, and any change order is written and approved before work proceeds. Call (561) 475-1246 for a survey that accounts for what your walls actually contain.
Completed impact-rated window and door systems qualify for the Florida Statute 627.0629 wind-mitigation credit, which can reduce homeowners insurance premiums by 10-45% depending on your carrier and the full envelope upgrade. We document every product approval number and installation detail needed for the uniform mitigation form. Call (561) 475-1246 to discuss how our specification affects your specific policy.
Yes, measurably. Low-E impact glazing with proper SHGC ratings reduces solar heat gain through south and west-facing openings, which matters in North Palm Beach’s ranch homes with extensive glass area facing the Intracoastal. The effect is most pronounced when the full envelope is upgraded, not individual units. Call (561) 475-1246 for a specification that includes energy performance data.
