How Much Does Window Repair Cost in St. Louis? [2025 Data]

The average window repair cost in St. Louis, Missouri, is $370—around 10% less than the national average—but it ranges from $192 to $566. In addition to the type of repair, the style and material of the window, local building codes, and climate can affect your total costs.

Window Repair Cost Factors

It’s not just the type of damage and its extent that influences window repair costs in St. Louis, Missouri. Your window materials and local regulations also play a part.

Type of Repair

While you may pay $25 to replace a broken latch, the cost to replace window glass in a large window could be over $1,800. Rotten frame replacement can cost up to $800—or more if you’re in an old St. Louis home that needs to conform to local historic building codes. This is a common repair for wood frames in the city’s humid climate.

If you’re replacing a broken pane, it pays to invest in higher-cost energy-efficient types of window glass. Insulating against the city’s cold winters and hot summers can help reduce your HVAC bills. The International Energy Conservation Code specifies that replacement window glass in St. Louis should have a U-factor of 0.40 or 0.35, depending on which part of the city you live in.

Type of Window

Repair costs in St. Louis depend on the type of windows your home has. There is a wide range of architectural styles in the city. Repairs to a large bay or historically significant window in a Queen Anne or Victorian-style home will cost more than a standard double-hung style in a modern home or a tiny transom window above the door in your traditional St. Louis row house.

Number of Panes

You might have multi-pane windows if you live in a historic St. Louis home. When windows feature 6-over-6, 9-over-9, or 12-over-12 pane configurations, expect costs to be higher than for simple double-pane designs common in modern homes.

Window Material

Repair costs vary depending on the type of window frame material. In the humid climate of St. Louis, wooden frames are more susceptible to rotting. Unless you have high-quality, sealed hardwood, your windows will last longer if you select moisture-resistant materials like vinyl or fiberglass. Wooden frame repairs can also be more costly in large windows in historic homes when you have to conform to local preservation codes. 

Expensive repairs for vinyl frames include replacement if they’re warping in the city’s scorching summers. If you need to replace heat-absorbing aluminum frames, it can be worth investing in more energy-efficient materials.

Window Repair Pro Costs

While learning to caulk a window is a project most handy homeowners can handle, often window repairs are best left to a local window repair contractor. If you must repair a rotting window frame, a professional will be familiar with St. Louis building codes and historic preservation regulations. They’ll also ensure the repair is safe and secure, keeping your window weatherproof for longer.

Labor

According to the Bureau of Labor Statistics, construction labor costs are 15% higher in Missouri than the national average. Expect to pay $35 to $105 per hour for window repair labor costs in St. Louis.

Permit

Standard window repair work, such as caulking or broken glass replacement, rarely requires a building permit in St. Louis. However, if you’re replacing a rotting frame or making substandard repairs or structural or size changes to windows in a historic home, always check the Residential Repairs & Renovations Checklist for St. Louis to see if your work needs to conform with any particular codes.

Tipping

While not necessary, tipping your contractor 10% to 20% of the original project estimate is common practice when they do a good job. Budget between $20 and $100 for the average tip for window repairs in St. Louis. If a cash tip isn’t within your budget, leave a glowing online review.

Does Window Repair Increase Home Value?

Whether your window repairs increase your home’s value depends on what work your contractor completes. Redoing seals or repairing window tracks likely won’t entice buyers, but replacing rotten frames or cracked panes does more than just boost your curb appeal. Major repairs can have an average return on investment (ROI) of 60% to 75% in St. Louis. Plus, they can make your windows more energy efficient and your home more comfortable.
