Windows on a brick house

Homes in Lake St. Louis have a median age of 39.3 years. However, window seals can usually last about 20 years. Air gaps and cracks can raise heating and cooling costs, strain your HVAC system, and shorten its lifespan — but we can help.

Zen Windows St. Louis provides the highest-quality window options in the St. Louis area. With direct access to the owner and exceptional customer service, we offer a simple, hassle-free process.

We’re changing the way people buy windows. Contact Zen Windows St. Louis today to schedule a free, no-hassle quote and window installation consultation.

We Offer Top-Quality, Energy-Efficient Windows

Aside from boosting your home’s curb appeal, replacement windows can increase your resale value by $11,000. Select from the latest options like double-hung windows, a go-to style for energy efficiency and providing natural light in homes. When requesting your free estimate, ask us about replacement window tax credits to help offset the purchase price.

Our Window Replacement Options

Window styles meet different ventilation and aesthetic requirements. For long-term performance, ProVia provides low-maintenance vinyl with energy-efficient insulation levels and coatings.

A popular style, SoftLite, offers innovative products with lifetime manufacturer warranties in addition to our labor warranty for twice the coverage at no additional cost. Joyce windows can add functionality and beauty with thermal efficiency and include different configurations, colors, and sizes.

Our window options include:

  • Awning windows: With hinges at the top, they crank outward.
  • Bay windows: Bays have three windows projecting out, with the two side windows being double-hung or casement.
  • Bow windows: Similar to bay windows, bows have four to five windows that open or are picture windows.
  • Casement windows: With hinges on the left or right side, they crank outward.
  • Double-hung windows: Gliding up or down, they can open with an upper and lower sash.
  • Hopper windows: With hinges at the bottom, these swing inside.
  • Round-top windows: Sometimes hung above a door as picture windows, these are popular above casements and double-hung windows.
  • Sliding windows: These open horizontally with one or more sashes.
  • Specialty-shaped windows: Installed adjacent to rectangular windows, these are visually appealing.
