Winterizing Your Concrete: A St. Louis Homeowner's Guide

How to Prepare Your Concrete for Winter in St. Louis

As the Gateway Arch casts longer shadows and the Cardinals wrap up their season, St. Louis homeowners know it’s time to prepare for winter. At St. Louis Concrete Works, we understand that our unique climate poses specific challenges for concrete surfaces. This guide will help you protect your concrete investments through the cold months ahead.

Winterizing Concrete

Why Winter Prep Matters in St. Louis

St. Louis winters bring a triple threat to concrete:

  1. Freeze-thaw cycles
  2. De-icing chemicals
  3. Moisture penetration


Our location along the Mississippi River adds humidity to the mix, increasing the risk of moisture-related damage. Proper preparation can prevent costly repairs come spring.

Step-by-Step Winterization Process

1. Thorough Cleaning

Start with a clean slate:

  • Remove dirt, leaves, and debris
  • Power wash surfaces to remove stains
  • Allow surfaces to dry completely


Pro Tip: Choose a mild, sunny day in late fall for cleaning. The moderate temperatures are perfect for the next steps.

2. Inspect and Repair

Look for existing damage:

  • Fill small cracks (less than 1/4 inch) with a flexible concrete caulk
  • For larger cracks, call us for professional repair
  • Check for proper drainage to prevent water pooling


Remember: Addressing small issues now prevents big problems later.

3. Apply a Quality Sealer

A good sealer is your concrete’s winter coat:

  • Choose a penetrating sealer for maximum protection
  • Apply when temperatures are between 50°F and 80°F
  • Allow 24 hours of dry weather after application


St. Louis Concrete Works Recommends: Our specially formulated winter-grade sealer, designed to withstand our harsh freeze-thaw cycles.

4. Create a Barrier

Protect concrete edges where they meet soil or grass:

  • Apply a concrete edging system
  • Or, create a gravel barrier to improve drainage


This step is crucial in areas like South County, where clay soils retain moisture.

5. Prepare for Snow Removal

Be ready before the first flakes fall:

  • Invest in plastic snow shovels to prevent surface scratching
  • Have sand or kitty litter on hand for traction (avoid salt on new concrete)
  • Consider a snow blower with rubber-tipped blades for large areas

Special Considerations for St. Louis Concrete

For Stamped Concrete

Popular in areas like Frontenac and Ladue, stamped concrete requires extra care:

  • Apply a heavier coat of sealer to protect intricate patterns
  • Use a soft bristle brush for snow removal to preserve textures

For Exposed Aggregate

Common in mid-century modern homes in Crestwood or University City:

  • Ensure all loose stones are secure before sealing
  • Use a slightly more flexible sealer to accommodate movement

For Concrete Driveways

From the sloping streets of Clayton to the flat expanses of St. Charles:

  • Pay extra attention to the area where your driveway meets the street
  • Consider installing heating cables for high-traffic areas

When to Call the Professionals

While many winterization steps are DIY-friendly, some situations call for expert help:

  • Significant cracking or unevenness
  • Signs of soil erosion around concrete
  • Installation of advanced drainage systems
