Frequently Asked Questions

Water enters small cracks, freezes overnight, and expands with enough force to widen pavement. When temperatures rise, ice melts and leaves larger voids that collect more water. This cycle repeats throughout Maine winters, turning hairline cracks into potholes and requiring extensive repairs if untreated.

Wait until fresh asphalt fully cures before applying sealcoating. New pavement needs time to harden and release oils. Sealing too early traps moisture and prevents proper curing, which weakens the surface and reduces the effectiveness of the protective barrier.

Cracks must be cleaned and filled first so sealcoating can bond to a stable, uniform surface. Untreated cracks allow water penetration beneath the sealant layer, which causes the coating to fail prematurely. Proper crack treatment prevents moisture infiltration and extends the life of both the repair and the sealcoat.

Moisture seeps through cracks into the base layer, then freezes and expands during cold nights. Repeated freeze-thaw cycles weaken the base material while traffic stress breaks apart the weakened asphalt above. Once the surface layer collapses, the depression collects more water and deteriorates rapidly.

Traffic volume, weather exposure, and pavement age all affect sealing frequency. High-traffic lots near salt-treated roads typically need protection every two to three years. Properties with lighter use or covered areas may extend intervals, but annual inspections identify when protection is wearing thin.

Repairs address localized damage like cracks, depressions, or small failed areas while preserving the rest of the pavement. Replacement becomes necessary when widespread cracking, drainage failure, or base deterioration affects most of the surface. Evaluating the extent of damage determines which approach delivers better long-term value.

Sealcoating protects the surface but doesn't fill or repair cracks. Cracks must be cleaned and sealed separately before applying the coating. Sealcoating over untreated cracks allows water to continue penetrating the pavement, which leads to faster deterioration and coating failure.

Edging creates clean boundaries and prevents sealer from spreading onto grass, concrete, or landscaping. Proper edges also ensure consistent thickness along pavement perimeters where deterioration often starts. This preparation step protects surrounding areas and delivers a professional-looking finished appearance.

UV exposure dries out binding oils, surface texture roughens, and small cracks appear. Water enters these cracks, weakens the base through freeze-thaw cycles, and creates potholes. Without maintenance, pavement deteriorates from surface wear to structural failure, eventually requiring complete replacement instead of affordable preservation.

Pooled water softens asphalt, penetrates cracks, and saturates the base layer beneath the surface. Freeze-thaw cycles in Maine expand trapped moisture and break apart weakened pavement. Installing channel drains redirects water away from the surface before saturation occurs, which prevents recurring pothole formation and premature deterioration.

Repaint when lines become difficult to see from a driver's seat or when markings no longer guide traffic clearly. Faded striping creates confusion, reduces parking efficiency, and signals poor property maintenance. Combining striping with lot sealing ensures fresh markings bond properly to a clean, sealed surface.
