K&O Sealed LLC provides residential driveway sealcoating and commercial pavement maintenance throughout Rapid City and surrounding Black Hills communities:
Owner Evan Kordonowy brings over 20 years of hands-on experience in asphalt sealcoating, crack filling, and pavement preservation. Every project is personally estimated, prepped, and sealed by Evan rather than handed off to seasonal sub-crews.
Most residential driveways in Rapid City and the Black Hills cost between $165 and $350+ depending on square footage and surface condition. Use our Instant Estimate Calculator above for an immediate ballpark range.
We recommend sealing every 2 to 3 years. Rapid City and the Black Hills experience over 100 freeze-thaw cycles annually, plus snowplow abrasion, de-icing salts, and high-altitude UV exposure that dry out unprotected asphalt and cause raveling.
Sealer only bonds to clean, dry pavement. Before sealing, we mechanically trim grass edges, wire-brush and power-blow dirt and loose aggregate, prime oil drips, and seal open cracks so water cannot penetrate and freeze underneath your driveway.
In warm, sunny South Dakota weather, the surface is dry to the touch for foot traffic in 4 to 8 hours. Keep vehicles off the driveway for 24 to 48 hours for a full, tire-ready cure.
Yes! As shown in our Before & After Gallery, K&O Sealed services commercial parking lots, ADA handicap stall markings, church/HOA properties, and private ranch roads across the Black Hills — including evening and weekend scheduling.
Send your instant estimate directly to Evan's inbox (evankordonowy@gmail.com) or call/text anytime. We make it straightforward to get your asphalt sealed right.
