Patio Doors in the South Chicagoland Suburbs

Getting a new patio door is a big decision; it impacts your home's appearance, energy efficiency, and comfort. Whether you're replacing a worn-out sliding door or upgrading to a swinging or garden patio door, it’s important to choose a company you can trust.

At Welsh Windows Plus, we’ve helped thousands of homeowners across Chicagoland, especially in Alsip, Tinley Park, Orland Hills, Oak Lawn, and nearby suburbs. We replace and install high-quality patio doors that fit their space, style, and budget.

Here’s what you should know before getting started.

Patio & Sliding Doors: What to Know

When selecting a patio door, there are several styles to consider, each with its own benefits.

Sliding Patio Doors

• Pros: Space-saving, modern look, easy to operate.

• Cons: Tracks may require regular cleaning.

• Durability: Typically last 20–30 years depending on material and usage.

• Maintenance: Keep tracks clear and clean glass regularly.

• Energy Efficiency: Many models are double or triple-paned with insulated glass.

• Installation: Requires precision to ensure a tight seal and smooth sliding.

Swinging (French-Style) Doors

• Pros: Elegant, wide-opening for airflow, multiple design options.

• Cons: Needs more clearance space.

• Durability & Maintenance: Hinges and seals may require upkeep.

• Aesthetics: Ideal for traditional homes with a more classic style.

Patio Door Installation

Installing a patio door isn’t just a cut-and-paste job, it requires precision and expertise.

DIY or Call the Pros?

While it may seem like a DIY project, improper installation can lead to drafts, leaks, and alignment issues. Professional installation ensures:

• A watertight and energy-efficient seal

• Proper alignment and long-term durability

• Compliance with local building codes

At Welsh Windows Plus, our full-time, in-house team (no subcontractors) ensures your patio door is installed correctly the first time.
