Our Sliding & Patio Doors Services in Wellington

Patio Doors
Standard patio door replacement in Wellington’s 1985-2000 subdivisions starts with a measured survey of the existing rough opening. Most Olympia and Binks Forest homes were built with builder-grade aluminum sliders that carry no impact rating; we document the frame condition, the stucco line, and the sill pan so the new unit fits without disturbing surrounding finishes. For homeowners still within a builder warranty period, we size the replacement to the original frame dimensions and preserve the existing stucco termination to avoid voiding coverage. Typical range: $1,800-$3,400 installed.

Impact Sliding Glass Doors
Wellington sits 12-15 miles inland, which reduces salt-spray corrosion on aluminum frames compared to coastal Palm Beach, but the village is still fully inside the High-Velocity Hurricane Zone. Any permitted replacement must carry Miami-Dade NOA or Florida Product Approval documentation. We specify impact sliding glass doors from ES Windows and ECO Window Systems rated for the wind loads at your specific address, and we pull the permit and schedule inspection as part of the scope. Insurers in Palm Beach County now aggressively require wind-mitigation inspections; an impact-rated slider with the proper documentation triggers the premium discounts that non-renewal notices are designed to force. Typical range: $3,200-$5,800.

Sliding Glass Door Replacement
The most common call we get in Wellington is not about broken glass. It’s about a 1990s aluminum slider that no longer rolls, seals, or locks. The original tracks pit from daily summer thunderstorms and humidity; the weatherstripping hardens and cracks; the laminated glass interlayer fogs between panes. We remove the unit, inspect the sill pan and rough opening for water intrusion, and install a replacement sized to the existing stucco line. In Olympia, we replaced a builder-grade aluminum slider off a 1990s family room after the original jamb had corroded and the laminated glass interlayer had fogged; the customer was in a builder warranty window, so we documented the existing rough opening, kept the stucco line intact, and used a PGT impact slider sized to the original frame to preserve the warranty. The new unit’s low-E insulated glass unit cut the afternoon heat load and gave them the wind mitigation credit their carrier kept asking about. Typical range: $2,400-$4,500.

Impact French Patio Doors
French patio doors in Wellington are often the first upgrade homeowners make after a wind-mitigation inspection flags the original builder-grade slider. Impact French systems from Therma-Tru and Mr-Glass swing or fold, depending on the opening width and the room’s traffic pattern. We see these specified frequently in Binks Forest and the newer sections of Olympia where HOA architectural review committees require a specific aesthetic. The impact rating is non-negotiable for permit approval, but the grille pattern, finish, and hardware selection are where we match the committee’s guidelines. Typical range: $4,200-$7,800.

We specify from eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - chosen by what the opening requires, not by what is in stock. For Wellington’s inland climate and 1980s-era housing stock, we lean on ES Windows and ECO Window Systems for impact sliders in the standard replacement range, and Therma-Tru for French and hinged systems where the HOA or architectural review has aesthetic requirements. Parts and hardware orders ship to our South Florida warehouse, so Wellington jobs don’t wait on cross-country freight. Our Sliding & Patio Doors team keeps common frame extrusions and roller assemblies on hand for service calls.
Common Sliding & Patio Doors Problems We See in Wellington Homes

- Track pitting and weatherstripping failure on 1985-2000 aluminum sliders. Wellington’s daily summer humidity and thunderstorms degrade the original nylon rollers and pile weatherstripping long before the glass itself fails. The unit starts leaking air and water, and the operating force increases until the door won’t move.
- Non-impact laminated glass that fails wind-mitigation inspection. Builder-grade sliders in Olympia and Binks Forest often have glass that looks intact but carries no large-missile rating. Once a wind-mitigation inspection is filed, the insurer issues a non-renewal notice and the replacement becomes time-sensitive.
- Equestrian-property outbuilding doors without engineered design pressure documents. Barns, tack rooms, and covered arena entries on Wellington’s show-season estates fall under Palm Beach County wind-load code. Sliders and bifolds installed without Miami-Dade NOA or Florida Product Approval paperwork fail code enforcement review, typically discovered mid-permit during the January-April rush.
- Stucco-line disruption from improperly sized replacement frames. Crews unfamiliar with Wellington’s 1990s construction methods sometimes remove too much surrounding material, voiding builder warranties and triggering HOA repair requirements.

FAQs - Sliding & Patio Doors in Wellington

It can, if the replacement disturbs the stucco line, sill pan, or rough opening beyond the original frame dimensions. We document the existing conditions, size the new unit to the original frame, and preserve the surrounding finishes so the warranty remains intact. Call (561) 461-2062 and we’ll review your warranty documents during the free survey.
Yes, if your carrier participates in the Palm Beach County wind-mitigation discount program and the door carries Miami-Dade NOA or Florida Product Approval with the proper installation documentation. We provide the permit, inspection record, and product approval paperwork as part of the standard scope. Call (561) 461-2062 to confirm your carrier’s specific discount schedule.
Most Wellington homeowners see a 15-25% reduction in cooling load for the rooms served by the replaced sliders, measured by comparing summer utility bills before and after. The low-E coating and argon fill block infrared heat, and the improved weatherstripping eliminates the air infiltration that original 1980s units allow. Your actual savings depend on the home’s orientation, shading, and overall envelope condition. Call (561) 461-2062 for a free estimate with performance specs.
Yes. Palm Beach County code enforcement applies wind-load requirements to agricultural outbuildings on equestrian properties, so barn and arena sliders and bifolds need the same Miami-Dade NOA or Florida Product Approval paperwork as residential units. Out-of-county crews often discover this mid-permit during show season. We engineer the specification from the measured survey and submit the documentation with the permit application. Call (561) 461-2062 to schedule a survey of your outbuilding openings.
A standard sliding glass door replacement keeps the same operating style - one or two panels that roll on a track - while upgrading the glass, frame, and hardware. An impact French patio door changes the operating style to hinged or folding panels that swing wide, which suits wider openings and different traffic patterns. French systems cost more, require more wall space for panel swing, and are frequently specified by Wellington HOA architectural committees for aesthetic consistency. Both carry impact ratings; the choice depends on your opening dimensions, traffic needs, and any governing design rules. Call (561) 461-2062 and we’ll measure your opening, review your HOA documents, and show you both options with written prices.
