Three Lakes sits in Miami-Dade County’s inland corridor, where the combination of afternoon thunderstorms, high humidity, and the occasional tropical system puts real demand on exterior door systems. We’ve replaced sliding doors in Three Lakes homes where the original vinyl frames had warped from heat cycling, where single-pane glass made utility bills climb through summer, and where outdated latching mechanisms no longer met current wind-load requirements. Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3, Verified Crews. Live phone coverage is available 24/7, not a voicemail queue.

What Our Sliding & Patio Doors Service Includes

Patio Doors

Patio doors are the primary exterior door system connecting living spaces to outdoor areas - typically a single swinging door, French door pair, or multi-panel sliding unit. In Three Lakes, we see patio door failures most often in homes built between 2005 and 2015, where original builder-grade units used aluminum frames without thermal breaks and single-strength glazing that no longer meets current energy code. Sightline measures every opening for square, plumb, and level, then specifies the replacement unit from our eight manufacturer lines based on the opening’s actual dimensions, the home’s exposure, and the customer’s performance requirements. The measured survey becomes the written quote - Haven Clause 1 - and the customer keeps both documents.

Impact Sliding Glass Doors

Impact sliding glass doors combine laminated or tempered impact-rated glazing with reinforced frames engineered to meet Miami-Dade County’s HVHZ (High Velocity Hurricane Zone) requirements. Three Lakes falls within this zone, which means any new or replacement sliding glass door must pass missile-impact and cyclic-pressure testing. We specify impact sliding glass doors from PGT, CGI, CWS, and ES Windows, matching the product to the opening’s wind-load calculation and the customer’s budget tier. Every impact unit we install carries a documented photo record of the installation, including frame fastener spacing, sealant application, and operational testing - Haven Clause 4, Evidence on Every Job.

Sliding Glass Door Replacement

Sliding glass door replacement becomes necessary when rollers fail, tracks corrode, frames leak, or the glazing no longer performs to current standards. In Three Lakes, we regularly find original sliding glass doors from the 1980s and 1990s with anodized aluminum frames that have lost their weatherstripping compression and steel rollers that have ground flat against aluminum tracks. Our replacement process removes the entire frame system, inspects the rough opening for water damage or termite activity, installs a new sill pan with proper end dams, and sets the replacement unit on composite shims with structural fasteners at engineered spacing. The old unit is hauled away, and the customer receives the photo record and written warranty before we leave.

Impact French Patio Doors

Impact French patio doors pair the traditional hinged operation and divided-lite aesthetics with laminated impact glazing and reinforced stile-and-rail construction. These units are specified for Three Lakes homes where the architectural character calls for a more formal entry to outdoor living spaces, or where a wider rough opening suits a double-door configuration better than a single sliding panel. We source impact French patio doors from Therma-Tru and ViewLux, with options for fiberglass or steel construction, multi-point locking hardware, and various grille patterns. The measured survey captures not just the opening dimensions but the swing direction, threshold transition, and interior trim integration - details that determine whether the installation looks like a replacement or like the door was always meant to be there.

Screen Door Installation

Screen door installation addresses the need for insect ventilation without sacrificing the primary door’s security or weather performance. We install screen doors as companions to swinging patio doors and as retractable screen systems for sliding glass door openings in Three Lakes homes. The product selection depends on the primary door’s operation, the available pocket depth for a retractable housing, and whether the customer wants a fixed mesh panel or a motorized screen that stores in a header cassette. Every screen door is measured to maintain proper clearance and mesh tension, and we document the hardware mounting and mesh specification in the job photo record.

Brands We Service for Sliding & Patio Doors

We work with eight verified manufacturer lines, specified by performance tier and price range rather than by what happens to be in stock. For sliding and patio doors in Three Lakes, we most often draw from CWS, ES Windows, ECO Window Systems, and Mr-Glass.

CWS sliding door systems are specified for mid-tier replacement projects where the customer wants improved energy performance and smooth roller operation without the premium of full impact rating - though CWS does manufacture HVHZ-compliant units when required. We’ve installed hundreds of CWS sliding and patio door systems across Miami-Dade County and maintain direct distributor relationships for warranty support and parts availability. ES Windows produces impact-rated sliding and French door systems with some of the tightest frame sightlines in the industry, which matters in Three Lakes homes where the customer wants maximum glass area and minimal visible frame. ECO Window Systems offers a strong value position for rental properties and investment homes in communities like Palmetto Estates and Richmond West, with sliding door units that meet current code without the premium features that owner-occupants typically specify. Mr-Glass specializes in custom and oversized sliding door configurations, including multi-panel lift-and-slide systems and pocket door applications where the panel stores inside the wall cavity - units we’ve installed in Pinecrest and Palmetto Bay homes with architectural requirements that standard product lines cannot meet. Whether you have CWS, ES Windows, ECO Window Systems, Mr-Glass, or any other make, we can service, repair, or replace it with a documented scope and written price before any work starts.

Before

After

Signs You Need Sliding & Patio Doors Right Now

• The door requires shoulder force to move on its track. This usually indicates collapsed rollers, a bent track, or frame racking that has thrown the panel out of square. Continued operation grinds the remaining roller surfaces flat and damages the track profile, turning a roller replacement into a full frame-and-panel replacement. In Three Lakes, we see this most often on south- and west-facing doors where thermal expansion has stressed the frame geometry.
• Water pools on the interior side after rain. Sliding door sill pans are designed to drain to the exterior through weep holes, but blocked weep channels, deteriorated sill seals, or improper flashing integration can redirect water inward. We’ve found water damage to subfloors and wall framing in Three Lakes homes where this symptom was ignored for multiple rainy seasons. The repair requires removing the unit, addressing structural damage, and reinstalling with proper sill pan and sealant detailing.
• Visible condensation between glass panes. This indicates seal failure in an insulated glass unit, meaning the argon or air fill has escaped and moisture has entered the cavity. The glass no longer provides meaningful thermal insulation, and the desiccant inside the spacer bar is saturated. In Three Lakes’s humid climate, this condition worsens quickly and cannot be reversed - the insulated glass unit must be replaced, or in many older frames, the entire door system is more cost-effective than custom glass fabrication.
• The latch no longer engages securely or the lock mechanism is loose. Security hardware on sliding doors depends on precise frame alignment and intact striker plates. Wear, corrosion, or frame settlement can cause misalignment that makes the lock cosmetic rather than functional. For Three Lakes homeowners, this is a genuine security concern - sliding doors are a common entry point, and a latch that doesn’t engage is a latch that won’t slow an intrusion.
• Your utility bill has risen without explanation. Older sliding doors with single-pane glass, non-thermal aluminum frames, or failed weatherstripping can account for significant cooling load in South Florida’s climate. We use infrared imaging during our measured survey to identify thermal bridging and air leakage at sliding door perimeters. The image becomes part of the documentation the customer keeps, along with the calculated improvement from replacement with a unit meeting current U-factor and SHGC requirements.

Our Sliding & Patio Doors Process - Step by Step

1. 1
   Schedule your measured survey. Call (786) 808-5792 or text to arrange a visit. Our technician arrives at the scheduled time - Haven Clause 2, Arrive on Schedule - in a marked vehicle, in uniform, with license number provided in advance. The survey takes 30-60 minutes depending on the number of openings and their accessibility.
2. 2
   We measure, document, and diagnose. Using digital measuring tools, we capture opening width, height, and squareness to 1/16 inch. We photograph the existing unit, the interior and exterior conditions, and any adjacent trim or flooring that affects installation. We test operation, inspect the sill pan and flashing, and note any structural concerns. For Three Lakes homes, we also verify the product wind-load requirement based on the home’s exposure and the Florida Building Code’s mapped wind speed for the area.
3. 3
   You receive the written quote - the same document as the survey. Haven Clause 1 means the measurement and the quote are the same document. The price is itemized by unit, with line-item costs for the door system, installation labor, disposal, and any additional work such as trim repair or sill pan replacement. There is no separate “final invoice” that differs from the quote. The customer approves in writing before any order is placed.
4. 4
   Installation by verified crews. The installation date is scheduled with a four-hour arrival window, confirmed by text the day before. Our technicians are background-checked and uniformed - Haven Clause 3 - and they arrive with the specified unit, proper fasteners, sealants, and flashing materials. The old unit is removed, the opening is inspected and prepped, and the new unit is set, leveled, fastened, sealed, and tested. The photo record is captured at each stage.
5. 5
   Final documentation and warranty. The customer receives the completed photo record, the written warranty documentation, and the 365-Day Done Right Promise - Haven Clause 5, No Surprises. If anything is not done right, we make it right. The job is not closed until the customer has all documents and has confirmed satisfactory operation of every unit.
