Trusted Window Installation for Lantana Homeowners
Window installation in Lantana typically costs $650-$2,400 per opening depending on frame type, glazing specification, and whether the unit is impact-rated for HVHZ compliance. Most residential projects in Lantana neighborhoods like Hypoluxo Island, Lantana Heights, and the Old Dixie corridor are completed in one to three days with the written price fixed before any work begins. Call (561) 461-2062 to schedule your measured survey - the document that becomes your quote.
We’ve installed and replaced windows across more than 18,000 openings since 2012, every one governed by the Haven Standard. In Lantana specifically, we regularly encounter salt-air corrosion on coastal-facing frames, original aluminum single-pane units from 1970s-1980s construction, and openings that no longer meet current Florida Building Code wind-load requirements after roof replacements or additions. Our measured survey captures frame squareness, sightline dimensions, wall thickness, and substrate condition - the customer keeps this document, and the written quote cannot deviate from it. That’s Haven Clause 1.
Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. Every completed job leaves a documented photo record and carries the 365-Day Done Right Promise: if it’s not done right, we make it right, written into the Haven Standard, not offered as a courtesy.
What Our Window Installation Service Includes
Single & Double Hung Windows
Single hung windows have one operable sash; double hung units allow both sashes to move, which matters in Lantana’s climate for directing airflow during shoulder seasons when humidity drops enough to open windows. We see these most in ranch-style homes east of Broadway and in Lantana Heights renovations where homeowners want to maintain exterior sightlines while improving ventilation. Sightline measures every opening for plumb and square, specifies sash balance ratings for the unit weight, and documents the existing stool and apron condition before removal - the customer receives this measured survey before any quote is prepared.

Horizontal Roller Windows
Horizontal roller windows operate on a track system with one or both sashes sliding sideways, making them practical for wide openings over kitchen sinks, in bedrooms with exterior walkways, or anywhere a projecting sash would obstruct space. In Lantana, we install significant numbers of these in mid-century homes near the Intracoastal where original jalousie windows are being replaced with code-compliant units. Our survey notes track depth, weep hole placement for Florida’s driving rain, and whether the opening requires impact-rated glazing for HVHZ certification. We stock rollers and weatherstripping for CWS and ES Windows horizontal units to avoid supply delays.

3-Panel Sliding (3-Lite Roller) Windows
3-Panel Sliding (3-Lite Roller) Windows feature two operable sash panels flanking a fixed center lite, or a single operable panel with two fixed lites, depending on ventilation needs and structural load. These are increasingly specified in Lantana homes replacing old sliding glass door openings with window-height units, or in new additions where maximum glass area and operability must coexist. Our measured survey records the structural header capacity - critical in 3-panel spans over 96 inches - and we specify reinforcement or laminated glass accordingly. Every 3-lite installation includes a documented water infiltration test before final trim.

Casement Windows
Casement Windows hinge at the side and crank outward, catching cross-breezes off Lake Worth Lagoon more effectively than any other operable type. We install these frequently in Lantana’s elevated homes and in second-story applications where reaching a sliding sash is impractical. The crank mechanism requires precise frame installation - our survey measures rough opening tolerance to 1/8 inch and specifies hinge-side reinforcement for wind-load resistance. We document the operator arm travel and lock point engagement in the photo record; Haven Clause 4 requires evidence on every job.

Awning & Hopper Windows
Awning & Hopper Windows hinge at the top and open outward; hopper windows hinge at the bottom and open inward. Awnings are specified in Lantana for bathrooms and utility rooms where ventilation is needed during rain - the open sash sheds water rather than admitting it. Hoppers appear in basement-level applications and in specific architectural styles. Our survey notes clearance for the open sash, especially on awnings where exterior shutters or soffit details may interfere. We specify appropriate hardware finish and corrosion resistance for salt-air exposure, and we document the full arc of operation in the photo record.

Picture & Fixed Windows
Picture windows are non-operable units designed for maximum glass area and unobstructed views - common in Lantana homes where the priority is sightline to the water or landscaped courtyard rather than ventilation. Fixed windows serve the same function in smaller configurations. Because these units cannot open, proper specification of low-E coating, argon fill, and frame thermal break is essential; our survey records compass orientation to calculate solar heat gain coefficient requirements. We install picture units up to 60 square feet with engineered support and documented deflection calculations for the span.

Bay & Bow Windows
Bay & Bow Windows project in three planes, typically with a fixed center and operable flanks; bow windows use four or more planes to create a curved projection. These are specified in Lantana for expanded interior space, seated nooks, and enhanced natural light in living rooms and master bedrooms. Installation requires structural assessment of the cantilevered projection - our survey evaluates the existing header, specifies roof or soffit integration, and documents the angle of each plane. We coordinate with a structural engineer when the projection exceeds 24 inches or when the existing opening has been modified from original construction.

Garden Windows
Garden windows are mini-greenhouse projections, typically over kitchen sinks, with sloped glass top, fixed front, and operable side vents. In Lantana’s growing season, these extend herb and vegetable cultivation year-round. Our survey measures the existing cabinet and countertop clearance, specifies tempered glass for the sloped top per code, and documents the structural support for the projection weight. We integrate the garden window with existing backsplash and casing details to maintain interior finish continuity.

Brands We Service for Window Installation

We specify from eight manufacturer lines, selected by what the opening requires, not by what is in stock. CGI impact-rated aluminum frames are our specification for coastal Lantana openings within one mile of the Intracoastal, where HVHZ certification and salt-air corrosion resistance are non-negotiable. We’ve installed hundreds of CGI Estate and Sentinel lines and maintain direct technical support for warranty registration and finish-matching. CWS vinyl frames with reinforced sashes are specified for inland Lantana applications where thermal performance and cost efficiency balance - their Aria and WindPact lines carry NFRC ratings we document in the measured survey for customer comparison.
ES Windows aluminum and vinyl hybrid frames appear in our specifications for geometric and custom openings where standard rectangles won’t serve; their engineering department reviews our field measurements before fabrication, eliminating the dimensional risk of site-built solutions. ECO Window Systems provides our specification for energy-efficient retrofits in Lantana’s 1980s-1990s housing stock, where improving U-factor and SHGC without structural modification is the priority. Whether you have CGI, CWS, ES Windows, ECO Window Systems, or any other make, we can service, replace, or upgrade the installation with a written price before any work starts.

- Visible frame deterioration or corrosion. Aluminum frames with white oxidation streaks, vinyl with cracking or yellowing, or wood with soft spots or fungal growth indicate the frame has reached end of service life. In Lantana’s salt-air environment, coastal-facing windows often deteriorate faster than inland equivalents - we measure remaining wall thickness and specify appropriate replacement material.
- Condensation between glass panes. Fogging or moisture inside a sealed insulating glass unit means the seal has failed and the inert gas fill has escaped. The unit’s thermal performance is compromised; in summer, this manifests as the glass feeling warmer than adjacent walls. Our survey identifies which lites are affected and whether the sash is still manufactured for single-lite replacement or full-unit replacement is more cost-effective.
- Operable sashes that stick, bind, or won’t stay open. These symptoms indicate balance system failure, track deformation, or frame racking from structural settlement. In Lantana’s sandy soils, minor foundation movement is common and can distort window openings over time. We measure diagonal squareness and specify either sash replacement or full-frame installation to correct the underlying condition.
- Draft or temperature differential near the window. Air infiltration around the frame perimeter, or the glass surface feeling significantly colder or warmer than the room air, signals failed weatherstripping, inadequate insulation in the rough opening, or single-pane construction. Our survey includes a smoke-pencil test for air leakage and thermal imaging upon request to document the condition.
- Difficulty locking or engaging the sash. Lock mechanisms that require force, don’t fully engage, or have visible wear indicate either hardware failure or frame misalignment. Inoperable locks are a security and insurance compliance issue - we document lock function in the measured survey and specify replacement hardware or frame correction as indicated.
Our Window Installation Process - Step by Step

- 1
Measured survey and documentation. Our technician arrives at the scheduled time - Haven Clause 2 - with license identification, uniform, and background verification available on request. We measure every opening for width, height, squareness, and wall thickness; record frame condition, substrate type, and any structural concerns; and photograph the existing installation from interior and exterior. The customer receives this measured survey to keep; it becomes the basis for the written quote and cannot be altered without customer acknowledgment.
- 2
Written quote preparation. Within 24 hours of the survey, we deliver a line-item written quote specifying product manufacturer, model, performance ratings, installation scope, and total price. Haven Clause 1: the measurement and the quote are the same document. No verbal estimates, no range pricing, no “we’ll see when we get into it.” The price is fixed before any work starts.
- 3
Product ordering and scheduling. Upon acceptance, we order specified products with confirmed lead times and schedule installation. For standard CWS and CGI lines, this is typically 2-4 weeks; custom geometries or ES Windows engineered units may extend to 6-8 weeks. We communicate confirmed delivery dates and maintain the schedule - Haven Clause 2 again - with 48-hour confirmation calls.
- 4
Installation and real-time documentation. Our crew arrives with the specified products, removes existing units with protection for interior finishes, installs per manufacturer specification with proper flashing and sealant integration, and documents each phase photographically. The customer receives progress access to the photo record; Haven Clause 4 requires evidence on every job. We perform operational testing, water infiltration testing where applicable, and final cleaning before walkthrough.
- 5
Final walkthrough and warranty registration. We review operation, maintenance, and warranty terms with the customer; register products with manufacturers for full warranty coverage; and deliver the final documented photo record, the 365-Day Done Right Promise documentation, and a copy of the measured survey and final invoice - identical documents, as promised. Any concern within 365 days is addressed under Haven Clause 5: No surprises, including post-installation adjustments.
How Much Does Window Installation Cost in Lantana?
A typical single or double hung window installation in Lantana runs $650-$1,200 per opening for vinyl frames, $1,100-$1,800 for aluminum impact-rated units. Horizontal rollers and 3-lite sliders range $850-$1,600 depending on track configuration and screen inclusion. Casement and awning units with crank operators run $950-$1,750; picture and fixed windows $700-$2,400 depending on glass specification and span. Bay and bow projections start at $3,500 and range to $8,000+ with structural modification. Garden windows typically fall between $1,800-$3,200.
| Window Type | Vinyl / Standard | Impact-Rated Aluminum |
|---|---|---|
| Single/Double Hung | $650 - $1,200 | $1,100 - $1,800 |
| Horizontal Roller | $850 - $1,400 | $1,200 - $1,900 |
| 3-Lite Slider | $1,000 - $1,600 | $1,500 - $2,400 |
| Casement/Awning | $950 - $1,500 | $1,300 - $1,750 |
| Picture/Fixed | $700 - $1,400 | $1,100 - $2,400 |
| Bay/Bow | $3,500 - $6,500 | $5,000 - $8,000+ |
Several factors move these ranges: whether the installation is insert (sash-only replacement within existing frame) or full-frame (complete removal and replacement including interior trim); the need for structural header modification; stucco or siding repair and matching; and whether the opening requires HVHZ impact certification for Lantana’s location in Palm Beach County’s wind-borne debris region. Second-story and roof-scaffold access add labor cost. We specify all of these factors in the written quote - no line item is hidden.
To avoid overpaying, obtain a measured survey from any contractor and compare line-item scopes, not bottom-line prices. A lower quote with undefined “extras” will exceed a fixed written price. We offer a free second opinion on any written estimate: bring us a competitor’s quote and we will review it at no charge, identifying scope gaps, specification differences, and permit requirements they may have omitted. Our quote includes permit pulling, inspection scheduling, and all associated fees - no change orders for administrative costs.

Frequently Asked Questions - Window Installation in Lantana

Window installation refers to the complete process of fitting a new window unit into an opening, whether in new construction, an addition, or a full-frame replacement of an existing unit. Replacement typically means insert replacement, where only the sash and operating hardware are swapped within the existing frame; installation, in our usage, encompasses full-frame removal, rough opening preparation, and integration with wall systems. Sightline performs both, but specifies which approach the opening requires in the measured survey - insert replacement is not always possible or advisable, especially with deteriorated frames or out-of-square openings.
Most residential window installations in Lantana are completed in one to three days, depending on opening count, product type, and whether structural modification is required. A standard four-opening replacement with no complications is typically one day; a full-home project with 15-20 openings, or any project requiring bay/bow structural work, extends to two or three days. We specify the schedule in the written quote and adhere to it - Haven Clause 2 - with daily progress documentation in the photo record.
Window installation in Lantana ranges from $650 for a standard vinyl single hung to $8,000+ for a large impact-rated bay projection with structural modification. The specific price depends on frame material, glazing specification, opening condition, and access difficulty. Every Sightline quote is line-itemed, fixed, and delivered in writing before any work starts - Haven Clause 1. Call (561) 461-2062 for an exact quote; estimates are free and include the measured survey you keep.
Yes - we specify and install CGI, CWS, ES Windows, ECO Window Systems, and four additional manufacturer lines, selected by what the opening requires rather than inventory availability. We maintain direct technical relationships with each manufacturer for warranty support, finish matching, and engineering consultation on custom applications. If your existing windows are from any of these lines, we can service, repair, or replace with matching or upgraded specification.
We do not classify planned window installation as an emergency service - it is scheduled construction work requiring measured survey, product ordering, and permit coordination. However, we do respond to board-up and temporary securement needs when a window has been damaged by storm, impact, or break-in, with permanent installation scheduled to follow. For temporary securement in Lantana, call (561) 461-2062; live phone coverage is available 24/7 to dispatch a crew for documented temporary protection.
Every installation is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right, written into the Haven Standard, not a verbal assurance. This covers installation workmanship, operation, and weather integrity. Manufacturer warranties on products range from 10 years to lifetime depending on line and component; we register all products for full warranty coverage and document registration in the photo record. The two warranties operate in parallel - product defects are manufacturer responsibility, installation issues are ours.
Remove window treatments, wall hangings, and furniture within three feet of each opening; our crew will lay protection for floors and adjacent surfaces. Ensure access to electrical outlets for tools; if the opening requires exterior scaffold or ladder placement, clear the exterior zone of obstacles and notify us of sprinkler systems or shallow irrigation. Pets should be secured away from work areas. We specify any additional preparation in the written quote - no surprises on arrival day.
