Our Impact Windows & Doors Services in Lake Worth
Impact-Resistant Windows
Lake Worth’s building stock demands more than standard impact glazing. The pre-1980 CBS homes with original jalousie windows - still common from Southern Boulevard north to Lantana Road - cannot receive permits for single-opening replacement under current Florida Building Code. We engineer full-elevation solutions with products from PGT and CGI, specified by what the opening requires, not by what is in stock.
Hurricane Impact Windows
Every hurricane impact window we install in Lake Worth is labeled for Palm Beach County’s High-Velocity Hurricane Zone wind-load requirements. This is a non-negotiable code layer that adds cost and narrows acceptable product lines - but it also means the window survives what the Lagoon throws at it. We stock PGT and ES Windows lines rated for HVHZ loads, with U-factor and SHGC performance data documented in the written quote you keep.
Single Hung Impact Windows
Single hung impact units are the workhorse for Lake Worth’s vertical replacement market - the fixed upper sash and operable lower sash match the sightlines of original aluminum sliders without the air infiltration. On a 1962 CBS home off Federal Highway we surveyed last quarter, the original single-pane aluminum frames were pitted through at the jambs from salt spray, but the concrete-block bucks were sound. We shimmed new ViewLux single hung units with stainless-steel anchors and marine-grade fasteners - the coastal spec that costs more upfront and survives the decade.
Double Hung Impact Windows
Double hung impact windows serve Lake Worth’s historic district near Lake Avenue, where 1920s-1930s wood-frame bungalows and Mediterranean Revival cottages need operable upper and lower sashes for ventilation but can’t tolerate the water intrusion of original wood storms. Chronic humidity in these structures causes sill and header rot that must be addressed before any new unit is set - we document this in the measured survey, quote the remediation, and never bury it in a change order.
Horizontal Roller & Sliding Impact Windows
Horizontal roller impact windows dominate Lake Worth’s modern replacement market - the sliding sash design maximizes glass area and matches the aesthetic of original aluminum sliders. We specify Therma-Tru and CGI horizontal rollers with stainless-steel roller tracks and hardware, because the standard zinc-coated rollers seize within two seasons of Lagoon salt exposure. The coastal-spec hardware adds $40-$80 per opening. The inland-spec hardware adds a service call.
Wind Mitigation & HVHZ Code Compliance
Palm Beach County’s HVHZ designation means every impact window and door installed in Lake Worth must carry Florida Product Approval or Miami-Dade Notice of Acceptance. We verify this documentation before specifying any product - Haven Clause 5, No surprises. Your permit package includes the NOA or approval letter; your insurance inspector sees the sticker; your discount holds.

AfterTrusted Brands We Service in Lake Worth
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - specified by performance tier and price range, not by margin. For Lake Worth’s salt-air conditions, we typically specify PGT or CGI for coastal-exposed elevations, with stainless or hot-dip galvanized hardware substituted at order. We don’t stock inventory; we stock relationships with distributors who carry the coastal-spec SKUs we order. Turnaround from measured survey to install date typically runs 4-6 weeks for standard sizes, 6-8 weeks for custom geometric or oversized openings in historic district homes.
Common Impact Windows & Doors Problems We See in Lake Worth Homes
- Aluminum frame pitting on pre-1980 CBS homes. Original jalousie and single-pane slider frames along Dixie Highway and Federal Highway oxidize from Lake Worth Lagoon salt spray far faster than identical windows 8-10 miles west in Greenacres. The frame looks intact until you probe the jamb - then it crumbles.
- Seized steel hardware on coastal-spec impact doors. Standard door hinges, locksets, and fasteners corrode within a few seasons of salt exposure. We upgrade to stainless or hot-dip galvanized hardware on every Lake Worth install - the spec that survives.
- Degraded vinyl glazing seals and IG edge seals. Salt air accelerates seal failure, letting the laminated glass interlayer fog and the SHGC performance of Low-E coatings slip years before rated life. We specify marine-grade seal systems for Lagoon-proximate installations.
- The jalousie-window permitting trap. Because no louvered unit can earn an HVHZ large-missile rating, pulling a permit for even one jalousie window in Lake Worth triggers mandatory conversion of the entire home to impact-rated units - turning a single-window request into a whole-house project conversation.
Pricing for Impact Windows & Doors in Lake Worth, FL
Here’s what impact windows and doors cost in Lake Worth’s market, based on our 2024-2025 measured surveys and installed invoices:
| Service | Typical Range per Opening |
|---|---|
| Single hung impact window, standard size, coastal hardware spec | $650-$950 |
| Double hung impact window, standard size, coastal hardware spec | $780-$1,150 |
| Horizontal roller impact window, standard size, coastal hardware spec | $720-$1,050 |
| Impact sliding patio door, standard 6′ or 8′, coastal hardware spec | $2,400-$3,800 |
| Impact entry door with sidelite, Therma-Tru or ViewLux, coastal hardware spec | $3,200-$5,500 |
| Whole-house conversion, 12-18 openings, typical 1950s-1970s CBS home | $8,500-$16,000 |
| Whole-house conversion, 18-28 openings, larger home or full jalousie replacement | $14,000-$22,000 |
What moves the price: opening count, product line selected (PGT and CGI run higher than ECO or CWS, with performance data to match), coastal versus inland hardware spec, and whether the concrete-block bucks require repair or the wood-frame openings need sill and header remediation. The coastal-spec hardware adds 8-12% to material cost. The inland-spec hardware adds 100% to hardware replacement cost within five years in Lake Worth conditions.

FAQs - Impact Windows & Doors in Lake Worth
Because the Florida Building Code bans new louvered-window installation, and no jalousie unit can earn an HVHZ large-missile impact rating. When you pull a permit for any window replacement in Lake Worth, Palm Beach County requires the entire home to meet current impact standards - not just the opening being replaced. On a 1958 CBS home off Lake Avenue near the Museum of Lake Worth, we pulled a permit to replace one seized jalousie window and the city required the whole elevation to come up to code; the original aluminum sash was pitted through and the steel hinge pins on the adjacent jalousie door were frozen solid from salt spray off the Lagoon. We set new PGT impact-rated glazing units with stainless-steel anchors shimmed directly into the concrete-block bucks, and the homeowner cut cooling costs noticeably on the first full bill after the swap to Low-E insulated glass. Call (561) 421-3844 for a free measured survey - we’ll document every opening and quote the full scope in writing.
Yes. Palm Beach County’s High-Velocity Hurricane Zone designation requires either Miami-Dade Notice of Acceptance or Florida Product Approval for every impact window and door installed. We verify this documentation before specifying any product - it’s included in your permit package and visible to your insurance inspector. Call (561) 421-3844 and we’ll show you the approval letter for the exact product line we’re quoting.
Standard zinc-coated hardware and untreated aluminum frames show measurable degradation within 18-30 months of installation on Lagoon-proximate homes, compared to 8-12 years on inland properties in Greenacres or Royal Palm Beach. Stainless-steel and hot-dip galvanized hardware, specified in our coastal spec, shows no appreciable corrosion at the 5-year mark in identical conditions. The coastal-spec hardware adds $40-$80 per opening. The alternative is replacement hardware at $200-$400 per opening, plus labor, plus the interior damage from a failed window in a storm. Call (561) 421-3844 for an exact quote - estimates are free.
Yes, typically. Florida insurers offer wind mitigation discounts for homes with impact-rated coverings on all openings, documented by a licensed inspector’s form. The discount varies by carrier and policy, but the documentation we provide - Florida Product Approval or Miami-Dade NOA, installation permit, and final inspection - is what your inspector needs to verify. We don’t guarantee a specific dollar savings; we guarantee the documentation will be correct. Call (561) 421-3844 to schedule your survey and we’ll review what your policy requires.
Yes, with specific conditions. The original openings in Lake Worth’s historic district are often non-standard sizes, and chronic humidity has caused sill and header rot that must be addressed before any new unit can be set. We document this in the measured survey, quote the wood remediation separately, and specify custom-sized units from ViewLux or Therma-Tru that match the sightlines of original windows. The historic district has additional design review requirements; we coordinate permit submittals to include product images and finish samples as required. Call (561) 421-3844 for a free measured survey - we’ll inspect the openings, document the conditions, and quote the full scope in writing.
