If you’re evaluating how replace a sliding glass door, our guide walks you through choices, costs, and best practices to ensure a smooth, durable upgrade.

The 4-Step Door Replacement Process

Step 1: Measure opening and select the door

Accurate measurements are the foundation of a flawless installation. Our experts guide you through checking rough openings, head clearance, and swing direction to ensure compatibility with your existing framing. We also help you match door style, insulation, and hardware to your home’s architectural language.

Step 2: Remove old door and prep the opening

Safely removing the existing unit and preparing the opening minimizes surprises later. This stage includes addressing trim, weather barriers, and any settling or framing variances. Proper prep reduces costly rework and sets the stage for a airtight, weather-tight seal.

Step 3: Install, seal, adjust, and test operation

Installation combines precision with performance testing. Our team ensures the door sits plumb, vertically aligned, and smoothly operates across all movements. We apply high-quality sealants, adjust weatherstripping, and verify security hardware and locking mechanisms, simulating daily use to confirm reliability.

Step 4: Finishing touches and maintenance

Finishing touches include trim reattachment, final caulking, and surface protection. We provide maintenance tips to extend the life of your door system—think seasonal inspections, gasket checks, and cleaning recommendations that preserve hardware finishes and glazing integrity.

Types of Exterior Doors We Offer

Sliding patio doors vs French doors

Sliding patio doors maximize visibility and light with large glass panels and modern hardware. French doors offer a classic aesthetic and optional sidelights, creating an expansive entry that can be opened for a wide passage or closed for privacy. Both styles can be engineered for energy efficiency, security, and weather resistance, allowing you to tailor performance to Indiana’s climate.

Customizable exterior doors for Indianapolis homes

Our selection supports diverse architectural tastes, from contemporary to traditional. Customization options cover frame finishes, glass upgrades, grid patterns, and hardware finishes, ensuring your door complements your home’s exterior while delivering improved thermal performance and security features.

Choosing finishes, frames, and hardware

How to choose a window and door professional

Look for local experience, a portfolio of completed installations, and transparent pricing. Ask about warranty coverage, in-home measurements, and the availability of on-site consultations. A trusted professional will provide a written plan, material samples, and a clear timeline from contract to completion.

What to expect from installation and warranty

Expect careful fabrication, controlled demolition, and a tidy worksite. The installation should include proper flashing, sealing, and insulation to prevent drafts and water intrusion. A robust warranty typically covers doors, hardware, and installation labor for several years, giving you peace of mind for years to come.

Getting a quote and scheduling your project

Start with a comprehensive in-home or virtual assessment, where measurements and design preferences are confirmed. Request a written quote that itemizes materials, labor, permits (if applicable), and timing. Scheduling should accommodate your calendar, with clear milestones and contingency plans for weather-related delays.
