Services
Double-Hung Windows
Our double-hung windows feature tilt-in sashes for easy cleaning and optimal airflow control. Designed with durable vinyl frames and advanced weatherstripping, these windows provide excellent thermal efficiency while maintaining classic aesthetics. The patented balance system ensures smooth operation and long-term performance.
Patio Doors
Energy-efficient patio doors combine aluminum reinforcement with tempered glass for superior durability and security. Available with optional side lites and transoms, our doors create seamless transitions between indoor and outdoor spaces while maintaining exceptional insulation properties through multi-chambered vinyl profiles.
Casement Windows
Casement windows offer unobstructed views with left- or right-handed operation options. The compression seal design creates an airtight closure, while the heavy-duty hinges ensure decades of trouble-free use. Perfect for hard-to-reach areas requiring maximum ventilation and security.
Architectural Shapes
Custom-shaped windows including octagons, triangles, and trapezoids add unique design elements to any home. Engineered with the same energy-efficient technology as our standard windows, these specialty shapes maintain structural integrity while allowing creative architectural expression through seamless integration with other window types.
Replacement Windows
Our replacement window solutions include the 7800 Series with hidden constant-force balances and J-channel slots for easy installation. Designed to fit existing openings without structural modifications, these windows improve energy efficiency by up to 30% while maintaining the home's original aesthetic.

Report
I do not recommend seven D industries windows ..we have a new construction home and this is the first winter for the windows.. contacted them in November when window would not close.. that had many excuses why they could not send anyone out to look at why we are having this problem.. also Eliot will never answer phone calls or return phone calls.. i have just received a email stating that room temp and cold window will cause water and ice.. I think that we need to focus on the first problem of getting the window latched..

Thanks to my new Seven D windows, my furnace runs constantly and my house is freezing. My casement windows do not close. They are bowed. The lock mechanism can not engage. Customer service and communication has been horrendous. They sent the wrong size windows three times, which was a nightmare to coordinate during the build. The screens are shoddy compared to the Simonton windows we had previously purchased. Wish we would have stuck with Simonton but a middle man had convinced us to go with Seven D.
