      Frequently Asked Questions

      Find answers to common questions about window replacements and siding installation, maintenance, and service areas.

      Window replacement costs can vary widely, with prices ranging from $180 to $410 per window, averaging around $280 per window. However, the final cost depends on various factors such as the frame material, number of windows needed, and the type of glass chosen. For instance, basic double-glazed windows may cost $3 to $6 per square foot, while stronger tempered glass can range from $12 to $14 per square foot.

      We offer a wide range of windows, including double-hung, casement, sliding, awning and bay windows. Our team can help you choose the best option for your home. 

      While some window repairs like screen replacement, lock replacement, or window sealing can be simple and cost-effective DIY tasks, more complex jobs such as replacing a double pane or installing a new window are best left to professional window replacement installers. Full-house window replacements, in particular, are time-consuming and are better managed by experts like Tri-State Window & Siding.

      Yes, we offer flexible financing options to help make your window and siding projects more affordable. Get up to 60 Months With No Interest and No Money Down

      Yes, we offer warranties on both our windows and siding products.

      The window replacement process usually spans four to 15 weeks, covering initial consultations, measurement appointments, window ordering, and manufacturing. For smaller projects, the timeline tends to be shorter, but for whole-house replacements, it may take longer or involve multiple installation appointments. Once the windows are ready for installation, each window typically takes 30 to 60 minutes to install.
