If you’re considering options to replace a sliding glass door, our experts will outline configurations, energy ratings, and weather sealing strategies that maximize comfort and value for your Indianapolis home.

Types of Exterior Doors We Offer

Replace a sliding glass door: options and compatibility

Sliding glass doors are the most common backdoor choice for access to patios and decks, delivering expansive views and easy operation. At Modern Day Exterior Doors, you’ll find models that accommodate existing frames or allow for full frame replacements that optimize energy performance. Options include multiple hardware configurations, improved sill designs, and track systems engineered for reliable operation in varying weather. Our team will assess frame dimensions, threshold heights, and balcony or patio access needs to determine whether a full replacement, a retrofit insert, or a hybrid solution best preserves structural integrity while enhancing daylight and outdoor connectivity.

Other exterior door types: wood, vinyl, fiberglass

Wood doors offer natural warmth and customizable detailing, but require regular maintenance. Vinyl doors provide excellent value and weather resistance with low upkeep, while fiberglass doors combine strength with stable performance in extreme temperatures. Our selection covers entry doors, patio doors, and rear access doors, each available in a range of thicknesses, insulation levels, and decorative options. We help homeowners balance aesthetic goals with long-term durability, so your door system remains beautiful and secure for years to come.

Glass choices, finishes, and hardware

Glass configurations—such as Low-E coatings, tempered safety panes, and decorative obscure options—affect energy efficiency and privacy. Finishes span from contemporary matte to traditional wood-grain textures, while hardware choices include multi-point locking, helper levers, and corrosion-resistant finishes designed for humid or salty coastal climates. By pairing glass, finish, and hardware thoughtfully, you can achieve a cohesive look that complements your interior palettes and exterior claddings.

Customization Options for Your Home

Replace a sliding glass door with custom sizes and configurations

Custom sizing opens opportunities for perfect wall-to-wall configurations, large transoms for natural light, and tall or wide doorways that suit modern designs. We offer precise measurements, on-site templating, and engineered solutions that fit unique openings without compromising performance. If your doorway requires an unconventional width, height, or sash configuration, our team translates your architectural vision into a durable, code-compliant product that looks seamless with surrounding elements.

Color, trim, and grille patterns

Exterior color palettes and interior finishes create continuity with your home’s style. Choose from a broad spectrum of exterior paints, stains, and matte or glossy sheens, plus trim details and grille patterns that echo the house’s character—whether rustic, transitional, or ultra-modern. Grilles can be simulated divided lights or full-pane glass, allowing you to preserve traditional charm or pursue a sleek, uninterrupted glass appearance.

Energy efficiency upgrades and weather sealing

Energy performance is a critical consideration for Indianapolis homes. We bundle insulated frames, weather seals, and efficient glazing to reduce drafts and utility costs. Options like reinforced weatherstripping, high-performance spacers, and advanced glazing combinations help maintain interior comfort across seasons, minimize heat transfer, and support quieter indoor environments. Our customization extends to solar gains, UV protection, and moisture management to protect interior finishes while keeping energy bills predictable.

The 4-Step Door Replacement Process

Step 1: In-home measurement and assessment

Our process begins with precise measurements, door-sill checks, and an assessment of surrounding trim, flashing, and structural considerations. A seasoned professional reviews security requirements, hardware preferences, and any code or permitting considerations specific to Indianapolis neighborhoods. This upfront analysis prevents surprises during installation and ensures the replacement aligns with your long-term goals.

Step 2: Custom design and material selection

Based on your measurements and preferences, we present design options, material families, and performance ratings. You’ll review samples, color swatches, and hardware catalogs, with clear demonstrations of how each choice impacts energy efficiency, maintenance, and aesthetic resonance with your home. We collaborate to finalize a tailored package that balances form, function, and cost.

Step 3: Professional installation and quality checks

Our installers follow a rigorous protocol to ensure square fitting, proper sealant application, and accurate alignment of hardware. We perform leak tests, hardware operation checks, and movement assessments to confirm a smooth, quiet function. After installation, you’ll receive documentation on warranty coverage and care guidance to prolong performance and appearance.

Step 4: Post-installation follow-up and maintenance tips

We schedule a post-installation follow-up to address any questions and verify satisfaction. Maintenance recommendations cover recommended cleaning products, seasonal checks, and strategies to preserve seals and finishes. Regular inspections help catch minor issues before they become costly repairs, extending the life of your door system.
