Patio & Concrete Sealing in Castle Rock, CO

Protect and Enhance Your Concrete Surfaces

Concrete is strong—but it’s not indestructible. Without proper care, even the most durable surfaces will crack, stain, and fade over time. At Sweet Wash Pressure Washing LLC, we offer professional patio and concrete sealing services in Castle Rock, CO, designed to preserve and protect your exterior surfaces from Colorado’s harsh weather and daily wear.



Whether you're sealing a brand-new patio or revitalizing an old driveway, we use high-quality sealers and proven methods to deliver long-lasting results.

Why Seal Your Concrete or Patio?

Concrete and other porous surfaces are vulnerable to:

  • Water absorption and freeze-thaw cracking
  • UV damage and surface discoloration
  • Oil, rust, and grease stains
  • Mold, mildew, and algae growth
  • Efflorescence (white mineral streaks)

Our professional sealing process protects these surfaces by forming a barrier that repels moisture, enhances color, and makes cleaning easier. You get better longevity, fewer repairs, and a cleaner, more polished look year-round.

Surfaces We Seal

We specialize in sealing a variety of outdoor hardscape surfaces, including:

  • Concrete Patios – New or weathered, we'll seal and protect your patio for longer life and better appearance.
  • Driveways – Protect your concrete or paver driveway from oil, water, and seasonal damage.
  • Garage Floors – Sealing your garage slab adds protection from vehicle fluid leaks, salts, and heavy traffic.
  • Walkways & Sidewalks—Help prevent cracks, stains, and erosion on high-traffic paths.
  • Pool Decks—Make your pool area safer and more attractive with an anti-slip, water-resistant seal.

Our Concrete Sealing Process

We follow a thorough, step-by-step process to ensure the best possible outcome for every sealing project:

Step 1 – Surface Cleaning

We begin by pressure washing the area to remove dirt, algae, oils, and debris. This ensures the surface is clean and ready to absorb the sealant properly.

Step 2 – Crack Inspection & Prep

We inspect for surface damage, minor cracks, or problem areas. If needed, we address small repairs before sealing begins.

Professional-Grade Sealer Application

Using sprayers or rollers, we apply a premium concrete sealer suited to your specific surface and desired finish—matte, satin, or glossy.

Step 4 – Cure Time & Final Review

Once the surface is sealed, we allow for a full cure time and conduct a final walkthrough to ensure quality, uniformity, and customer satisfaction.
