What Our Sliding & Patio Doors Service Includes
Patio Doors
Patio doors are the primary entry point from your living space to outdoor areas, typically spanning 6 to 12 feet in width with either sliding or hinged operation. In Lantana, we see the most wear on units installed between 2004 and 2016, when builder-grade aluminum frames were common in developments west of Interstate 95 near Lantana Road. Sightline measures every opening to the sixteenth of an inch, specifies the exact product by performance tier, and delivers a written price before any demolition begins. The measured survey you keep becomes the scope document, and the final invoice matches it exactly.
Impact Sliding Glass Doors
Impact sliding glass doors are engineered to withstand wind-borne debris and cyclic pressure loads required by the Florida Building Code in High-Velocity Hurricane Zones. Lantana sits in Palm Beach County’s HVHZ, which means any new or replacement patio door must carry a Miami-Dade NOA or Florida Product Approval. We specify impact-rated units from CWS and ES Windows based on your exposure, whether your home faces the open fetch of the Lake Worth Lagoon or sits in a more sheltered interior lot near Hypoluxo Road. For homeowners in that area, we also offer Lake Worth Sliding & Patio Doors. Every impact door we install carries documented photo evidence of the fastening pattern, sealant application, and final operation test.
Sliding Glass Door Replacement
Sliding glass door replacement becomes necessary when rollers fail, frames corrode, or the thermal break degrades to the point of condensation between glass lites. In Lantana’s coastal environment, we regularly find salt-air corrosion on hardware installed within 2 miles of the Intracoastal Waterway, particularly in older homes near Ocean Avenue and the marina district. Our replacement process begins with a measured survey that records the exact rough opening, existing frame condition, and substrate type. We then specify the replacement unit by U-factor, SHGC, and structural rating, with the written price delivered before any commitment is required.
Impact French Patio Doors
Impact French patio doors combine hinged operation with full-glass panels and hurricane-rated construction, typically specified when homeowners want the traditional sightline of a French door with code-compliant protection. These units are heavier than standard French doors, often requiring reinforced hinges and multi-point locking hardware that must be precisely aligned during installation. In Lantana, we install impact French doors from ECO Window Systems and CGI for openings that face prevailing winds or that the homeowner intends to operate frequently. The measured survey includes a swing-clearance check, threshold height measurement for accessibility compliance, and verification that the existing header can support the additional dead load.
Screen Door Installation
Screen door installation addresses the secondary barrier that keeps insects out while allowing ventilation through your primary patio door opening. We install retractable screen systems, sliding screen panels, and fixed screen doors matched to the exact track configuration of your existing unit. In Lantana, screen doors see heavy use during the drier months from November through April, when homeowners open their living spaces to the patio. Our installations include a written measurement of the screen mesh type, frame color match, and hardware finish, with the same documented photo record provided on every job under Haven Clause 5.

Brands We Service for Sliding & Patio Doors
We work with eight manufacturer lines, specified by what your opening requires, not by what is in stock. For sliding and patio doors in Lantana, we most frequently specify CWS for mid-range impact-rated sliding systems with strong thermal performance, ES Windows for high-rise and exposure-heavy applications where structural ratings exceed standard residential requirements, and ECO Window Systems for impact French and hinged patio doors with clean sightlines and durable hardware. We’ve installed hundreds of CWS sliding units across Palm Beach County, including Sliding & Patio Doors in Wellington, and maintain direct technical support for warranty claims and parts replacement. Our ES Windows specifications include documented NOA verification for every unit, and we stock common replacement hardware for ECO French door systems to minimize lead times on repair calls.
Whether your current door is CWS, ES Windows, ECO Window Systems, or any other manufacturer, we can service, repair, or replace it. Our technicians carry the technical documentation for all eight product lines, and our measured survey process identifies the exact model and series when the original label has faded or been removed. If you’re considering a new installation, we specify by performance tier and price range, with the written quote naming the exact manufacturer and product series before any order is placed.

- The door requires shoulder force to move on its track. This indicates roller wear, track deformation, or frame settlement. In Lantana’s sandy soils near the water table, we see frame settlement compress the operating clearance until the sash binds against the header or sill. Continued operation in this condition damages the rollers, the track, and eventually the frame itself.
- Visible daylight or air movement at the perimeter seal. A properly installed sliding door should show no visible gap between the sash and the frame when latched. If you feel airflow or see light at the meeting stile or head jamb, the weatherstrip has degraded or the frame has shifted. This compromises both energy performance and security.
- Condensation between the glass lites that does not clear. This means the insulated glass unit has lost its seal and the desiccant is saturated. In Lantana’s humidity, this condition accelerates frame corrosion and mold growth on the interior trim. The glass unit requires replacement, and the cause of the seal failure must be diagnosed to prevent recurrence.
- Corrosion or pitting on the exterior frame, particularly at the sill. Coastal salt air attacks aluminum frames that lack a proper thermal break or anodized finish. We regularly find this condition on units within a mile of the Intracoastal, where salt spray deposits on horizontal surfaces. Left unaddressed, the frame weakens structurally and may no longer meet wind-load requirements.
- The lock no longer engages smoothly or the multi-point hardware is inoperable. Patio door locks are safety-critical components. If the deadbolt or hook bolt does not fully extend into the strike plate, the door cannot resist forced entry or positive pressure during a storm event. This requires immediate inspection and correction.
Our Sliding & Patio Doors Process - Step by Step
- 1
Measured survey and documentation. Our technician arrives at your Lantana home with a uniform, license number, and calibrated measuring tools. We record the rough opening width, height, and squareness to the sixteenth of an inch; the existing frame condition; the substrate type; and any structural or accessibility considerations. You keep a copy of this survey. It becomes the basis for the written quote and, if you proceed, the installation scope document.
- 2
Product specification and written pricing. Based on the survey, we specify the exact door system by manufacturer, series, size, glazing package, and hardware finish. The written quote names every line item, including the door unit, installation labor, sealants, fasteners, trim, and debris removal. Haven Clause 1 requires that this price cannot change once accepted. We also note any permit requirements for Lantana or Palm Beach County.
- 3
Permit application and scheduling. If your project requires a permit, we prepare and submit the application, including the product approval documentation and engineered drawings. In Lantana, most sliding and patio door replacements require a building permit and final inspection. We pull the permit, schedule inspections, and ensure the job passes before we consider it complete.
- 4
Installation with photo documentation. Our crew arrives on the scheduled date with the specified unit, verified against the survey dimensions. We remove the existing door, prepare the opening, install the new unit with code-compliant fasteners and sealants, and test every operating component. Haven Clause 4 requires documented photo evidence of the fastening pattern, sealant application, and final operation test. You receive this record.
- 5
Final inspection and 365-Day Done Right Promise activation. We walk the completed installation with you, demonstrate operation and maintenance, and provide the written warranty documentation. The 365-Day Done Right Promise, written into the Haven Standard, means that if anything is not done right, we make it right within one year of completion. No phone tag, no dispute, no additional charge.
How Much Does Sliding & Patio Doors Cost in Lantana?
A typical sliding glass door replacement in Lantana runs $2,800-$4,200 for a standard 6-foot vinyl or aluminum unit, $4,500-$6,800 for an impact-rated sliding system with low-E glazing, and $5,200-$8,500 for a larger multi-panel or lift-slide configuration with premium hardware. Impact French patio doors generally fall between $4,800 and $7,200 depending on width, hardware grade, and whether sidelites are included. Screen door installation, whether as part of a new unit or retrofitted to an existing opening, typically adds $380-$650.
Several factors move the price within these ranges. Frame material is significant: aluminum with a thermal break costs less than fiberglass or composite, but may not meet your energy performance target. Glazing options, including laminated impact glass, low-E coatings, and interior blinds, each add cost with measurable performance returns. Opening modification, such as enlarging the rough opening or installing a new header, requires additional labor and materials and is priced separately in the written quote. Finally, access conditions, including second-story installations or limited workspace, affect the labor calculation.
To avoid overpaying, obtain a written quote that names the exact product by manufacturer and series, not by generic description. Compare U-factor and SHGC values, not just price, since a lower-priced unit with poor thermal performance will cost more in energy over its service life. Sightline provides a free second opinion on any written estimate from another contractor, and our quote includes the measured survey you keep for comparison.
