Frequently Asked Questions

Common questions about custom/specialty windows in Des Moines, IA.

Basement egress window installation in Des Moines requires a minimum clear opening width of 20 inches, a minimum clear opening height of 24 inches, and a total net clear openable area of at least 5.7 square feet (5.0 square feet for at-grade floors). Additionally, the maximum sill height above the finished floor cannot exceed 44 inches, and exterior window wells must provide at least 9 square feet of floor area with an integrated escape ladder if the well depth exceeds 44 inches.
Full-frame replacement in Des Moines is superior for custom and specialty windows because it strips the opening down to the rough structural studs, exposing hidden wood rot and allowing complete sill pan flashing installation. While pocket insert installations are quicker, full-frame tear-outs maximize clear glass view area and guarantee continuous insulation around complex architectural angles.
Custom specialty window installations in Des Moines can be executed successfully throughout the winter months by employing room-by-room thermal isolation methods. Our teams work systematically, prepping rough openings from inside, utilizing cold-weather-rated polyurethane expanding foams, and closing wall openings quickly to limit heat loss and interior temperature drops.
Custom bay and bow windows in Des Moines prevent sagging over time through high-tensile stainless steel cable suspension systems anchored directly into your home's roof trusses or exterior wall headers. In addition, our installers build load-bearing knee brackets beneath the structural sill and seal insulated head and seat boards to stop thermal transfer and structural movement.

Why Custom Specialty Window Installations Demand Specialized Expertise

Non-standard window geometries introduce complex structural loads and unique water management vulnerabilities that standard rectangular replacement units never encounter. In Des Moines, where severe convective summer thunderstorms drive torrential rains at high wind velocities, non-standard window perimeters must have custom-formed head flashings, integrated drainage paths, and continuous self-adhered flashing membranes. Attempting to force modular units into irregular rough openings or failing to install proper sill pan flashing invites hidden perimeter water intrusion, saturated wall studs, and frame distortion. Our certified installers ensure every custom specialty unit meets ASTM E2112 installation standards and National Fenestration Rating Council (NFRC) structural load ratings.
