Spring Driveway and Patio Repair Guide

Assessing winter damage

Winter's freeze-thaw cycles are brutal on hardscaped surfaces. Water seeps into microscopic pores, freezes, expands by roughly 9%, and wedges cracks wider with every cycle. By spring you may find hairline cracks that have grown into quarter-inch fissures, heaved slabs, crumbling edges, and potholes in asphalt. Walk your entire driveway and patio with a notepad. Photograph every defect and measure crack widths — this inventory determines whether you need simple filler, partial replacement, or a full resurface.

Concrete crack repair

• Hairline cracks (under 1/4 inch) — clean out debris with a wire brush, then fill with a flexible concrete caulk or polyurethane sealant ($5–$15 per tube, DIY-friendly)
• Medium cracks (1/4 to 1/2 inch) — use a vinyl-concrete patching compound; press it in with a trowel and smooth flush ($20–$40 in materials)
• Wide cracks and spalling (over 1/2 inch) — these usually indicate structural movement; patching is temporary at best; plan for slab replacement ($3–$8 per square foot for a contractor)
• Heaved or sunken slabs — mudjacking ($500–$1,200) or polyurethane foam leveling ($800–$2,000) can raise slabs without full replacement

Asphalt driveway repairs

Asphalt is softer than concrete and more prone to depressions and potholes. Cold-patch asphalt ($15–$30 per bag) handles small potholes for a season, but hot-mix applied by a contractor lasts far longer. Alligator cracking — interconnected cracks resembling reptile skin — means the base layer has failed and patching won't hold; the section needs to be cut out and replaced ($4–$8 per square foot). Once cracks are filled, seal-coat the entire surface every 2–3 years ($0.15–$0.25 per square foot) to block water infiltration.

Paver releveling and joint repair

• Lift shifted pavers with two flathead screwdrivers, add or remove bedding sand to level, and reset
• Re-sand joints with polymeric sand ($20–$30 per bag) — it hardens when misted and resists washout
• Replace cracked or chipped pavers individually; keep a spare box from the original install for color matching
• If more than 30% of pavers have shifted, the base layer likely needs re-compaction — call a landscaper ($1,500–$4,000 for a typical patio)

Expansion joint maintenance

Expansion joints absorb seasonal movement and prevent random cracking. Over time the original filler dries out and crumbles. Remove old material with a utility knife, clean the channel, and install self-leveling polyurethane joint sealant ($8–$12 per tube). For driveways wider than two car widths, consider adding a new control joint cut with a diamond blade to guide any future cracking along a straight line.

Sealing: when and how

Seal concrete and pavers when water no longer beads on the surface. Apply a penetrating silane/siloxane sealer for concrete ($30–$60 per five-gallon pail, covers ~300 sq ft) or a wet-look acrylic for decorative pavers. Seal in spring after repairs are complete and temperatures are consistently above 50 °F. Avoid filming sealers on driveways in cold climates — they can peel. One coat every 2–3 years is sufficient.

DIY vs. professional: where to draw the line

• DIY-safe: crack filling, polymeric sand, individual paver replacement, sealing flat surfaces
• Call a handyman ($50–$100/hour): small slab patches, expansion joint replacement, minor paver releveling
• Call a carpenter or landscaper ($1,500–$8,000+): structural slab replacement, full paver base re-compaction, building or rebuilding retaining edges, large patio re-grading

When to call each trade

A landscaper is your best first call for paver patios, stone walkways, and any project involving grading or drainage. A handyman handles mixed small repairs — filling cracks, resetting a few pavers, replacing expansion joint sealant. A carpenter is ideal when the project involves structural wood borders, built-in seating around a patio, or pergola footings that have shifted. For any job involving more than 100 square feet of replacement, get at least three quotes and ask about base preparation — it's the single biggest factor in how long the repair will last.
