As an authorized Marvin installer, we ensure every window meets manufacturer specifications for optimal performance and full warranty coverage.
Certified by the Best
We carry exclusive certifications from leading manufacturers.
Marvin Signature Collection — Ultimate Customization
The Marvin Signature collection represents the pinnacle of window craftsmanship. Available in both the Ultimate and Coastline series, Signature windows offer the most extensive range of sizes, shapes, and custom options in the industry. The wood interior can be painted or stained to match any decor, while the Ultrex fiberglass exterior provides maintenance-free durability in all weather conditions.
Signature windows are the preferred choice for historic home restorations where matching existing window profiles is critical, as well as for custom new construction where architects specify exact dimensions and configurations. SPG works directly with Marvin to fulfill custom orders and ensure proper installation of specialty shapes including radius tops, trapezoids, and multi-unit assemblies.
Marvin Modern Collection — Contemporary Design
The Marvin Modern collection features clean, narrow frames that maximize glass area and natural light. Designed for contemporary and transitional architecture, Modern windows offer a minimalist aesthetic with expansive views. The collection includes large direct-set picture windows, casement units, and multi-slide door panels that create seamless indoor-outdoor transitions.
Modern collection windows use the same Ultrex fiberglass construction as the Signature line, ensuring durability and energy efficiency are not sacrificed for aesthetics. The slim sightlines are achieved through advanced engineering rather than material compromises, making these windows appropriate for both new construction and renovation projects that aim for a more contemporary feel.
Marvin Essential Collection — Performance & Value
The Marvin Essential collection delivers Marvin quality at an accessible price point. Built with a fiberglass exterior and a clean interior finish (paintable or prefinished), Essential windows provide excellent energy performance and durability without the premium cost of solid wood interiors. This makes them ideal for whole-home replacement projects where budget is a factor without compromising on quality.
Essential windows are available in double-hung, casement, awning, and picture configurations that cover the majority of residential window needs. The fiberglass frame resists expansion and contraction better than vinyl, maintaining tight seals and smooth operation over decades. For Indianapolis homeowners looking to upgrade from vinyl windows to a premium material, Essential is a natural step up.
Why SPG Installs Marvin
We install Marvin windows because they consistently deliver on the combination of beauty, durability, and energy performance that Indianapolis homeowners expect from a premium window. Marvin's Ultrex fiberglass outperforms vinyl in dimensional stability, meaning windows continue to operate smoothly and seal tightly through Indiana's temperature swings from subzero winters to 95-degree summers.
Our authorized installer status means our crews receive ongoing training from Marvin on proper installation techniques for each product line. Correct installation is critical for window performance — even the best window will underperform if improperly shimmed, sealed, or flashed. We coordinate with Marvin on custom orders and ensure every unit is installed to their specifications for full warranty coverage.

What Our Customers Say
SPG installed Marvin Signature windows in our 1920s Tudor home. The custom profiles matched the originals perfectly and the energy difference is night and day. Outstanding craftsmanship.
We chose Marvin Essential for our whole-home window replacement. The fiberglass frames feel much more substantial than our old vinyl windows and the installation team was thorough and professional.
The Marvin Modern casement windows SPG installed completely transformed the look of our kitchen. The slim frames let in so much more light. SPG handled the custom order and install seamlessly.
