Concrete Sealing in Ann Arbor, MI

Concrete sealing in Ann Arbor protects your driveway, patio, and walkways from the relentless freeze-thaw cycles and road salt that dominate our Michigan winters. The glacial clay soils under much of Ann Arbor's west and south side, combined with dozens of freeze-thaw swings each season, create ideal conditions for concrete damage, spalling, and surface scaling. A quality sealant keeps moisture out, preserves color on decorative finishes, and extends the life of your concrete investment by years. Whether your home sits in the Old West Side with its narrow 1920s driveways, or on the newer south-side subdivisions with wider patios and garage aprons, sealing is one of the smartest maintenance steps you can take. We handle sealing for homeowners across Ann Arbor, Ypsilanti, Saline, Dexter, and the surrounding townships, applying proven techniques that stand up to our tough climate.

Why Concrete Sealing Matters in Ann Arbor's Freeze-Thaw Environment

Ann Arbor winters are relentless. Frost penetrates more than three feet into the ground, and the seasonal cycle of freezing and thawing works water into concrete pores, causing it to expand and contract repeatedly. Add road de-icing salt, wet snow, and the occasional severe thunderstorm, and your concrete surfaces face constant stress. Sealing creates a protective barrier that blocks water and salt from penetrating the surface, dramatically slowing the damage process. Without sealing, even new concrete will show scaling, popouts, and discoloration within two to three winters.

• We prevent water absorption that leads to freeze-thaw cracking and spalling on driveways and patios.
• We block road salt and de-icing compounds from penetrating and discoloring concrete.
• We preserve the color and finish on stamped and decorative concrete, keeping investments looking like new.
• We extend the service life of concrete by 5 to 10 years when sealing is applied regularly.
• We reduce staining from oil drips, leaf debris, and weathering on exposed surfaces.

Sealing is not a one-time fix; it's a maintenance cycle that pays dividends every season.

Key info: A homeowner in Burns Park with a 1920s brick Tudor and a narrow original driveway can seal that surface in the early fall, protecting it through the harsh winter ahead. The same applies to the newer split-level homes on the south side with wide driveways facing years of salt exposure. Sealing early in the season (August through September) gives the product time to cure before the first hard freeze.

How We Seal Concrete in Ann Arbor: Process and Application

Sealing concrete properly requires careful surface preparation and the right product for the job. We start by cleaning the surface thoroughly, removing dirt, oil, mold, and any loose material. The concrete must be completely dry before sealing begins; we typically wait 48 to 72 hours after rain or pressure washing. We then apply a high-quality acrylic, polyurethane, or penetrating sealer depending on your surface type and the level of protection you need. The product cures over several days, during which we advise avoiding traffic and moisture.

• We pressure wash and clean the concrete surface to remove salt residue, dirt, and organic growth.
• We allow the surface to dry completely, typically 48 to 72 hours in dry weather.
• We apply the sealer evenly using professional equipment, ensuring full coverage and consistent thickness.
• We allow the product to cure for the full recommended time (usually 3 to 7 days) before exposing it to water or traffic.
• We schedule follow-up sealing every 2 to 3 years to maintain protection as the original coat wears.

This methodical approach ensures the sealer bonds properly and delivers years of reliable protection.

Local example: A homeowner in Kerrytown with a 50-year-old concrete patio had us clean and seal it in early September. The sealer cured through a dry spell, and when the first freeze came in November, the patio surface stayed intact while an unsealed neighbor's surface began to spall. Two years later, a second sealing application kept the finish looking fresh.

If your concrete needs repair before sealing, we offer concrete leveling and slab lifting to restore an even surface first.

Concrete Sealing Cost in Ann Arbor: What to Expect

Concrete sealing costs start at approximately $0.75 per square foot for basic acrylic sealing on a standard driveway or patio. The final price depends on several factors: the size of the area, the current condition of the surface, whether the concrete needs cleaning or repair before sealing, the type of sealer you choose, and the complexity of the application. A 500-square-foot driveway might run $375 to $500 for a single coat of acrylic sealer, while a polyurethane application on the same area could reach $600 to $800 for superior durability. Decorative or stamped concrete typically costs more because the sealer must protect intricate finishes and vibrant colors.

Several factors move the price up from that baseline. If your concrete has existing stains, mold, or heavy salt scaling, we spend additional time on cleaning and surface preparation. Larger areas benefit from slightly lower per-square-foot rates due to efficiency. Access issues (narrow driveways, steep slopes, or proximity to mature trees) may require specialized equipment. The sealer type you select makes a significant difference: penetrating sealers for freeze-thaw protection cost less than premium polyurethane formulas.
