September represents a critical transition month where the focus shifts decisively toward preparing your asphalt for winter's harsh conditions. Early fall is the last opportunity of the year to prepare your parking lot or driveway for winter, making September inspections and maintenance particularly important.
Comprehensive Pre-Winter Inspection
Begin September with a thorough inspection of your entire pavement surface:
- Identify all new cracks that developed during summer
- Locate areas where water pools or fails to drain
- Assess any damage caused by summer traffic and heat
- Document drainage problems that could worsen in winter
- Check transitions where asphalt meets concrete
- Evaluate striping visibility for winter conditions
Why September Crack Sealing is Critical
Crack sealing in September is perhaps the most important maintenance task you can perform before winter. Any crack that can hold water represents a potential point of freeze-thaw failure. When water enters cracks and freezes during winter, it expands with tremendous force, widening cracks and creating structural damage.
September provides ideal conditions for crack sealing, with temperatures typically ranging from 60°F to 75°F—perfect for proper material application and curing. Rubberized crack sealers applied in September create waterproof barriers that prevent winter water infiltration.
The Crack Sealing Process
Professional crack sealing involves:
- Thoroughly cleaning cracks to remove debris and vegetation
- Preparing cracks with routing or specialized cleaning tools
- Applying hot-pour or cold-applied rubberized sealant
- Ensuring complete filling and proper adhesion
- Allowing adequate curing time before sealcoating (if planned)
Drainage System Preparation
Proper drainage is essential for preventing winter damage. In September:
- Clear all gutters and downspouts of debris
- Inspect and clean storm drains and catch basins
- Remove leaves and debris that could clog drainage systems
- Identify and fix low spots where water collects
- Verify that water flows away from pavement surfaces
Planning Fall Sealcoating
If your pavement needs sealcoating, late September through early October provides an excellent window. Fall sealcoating offers several advantages:
- Protection throughout the winter months
- Reduced risk of water infiltration during freeze-thaw cycles
- Enhanced curb appeal heading into holiday seasons
- Moderate temperatures for proper application and curing
However, all crack sealing must be completed before sealcoating can be applied.
Addressing Minor Repairs
September is the time to address minor damage that cannot wait until spring:
- Fill small potholes with appropriate patching materials
- Repair edge deterioration
- Fix minor surface defects
- Treat oil stains that could worsen over winter
Final Surface Cleaning
Before winter arrives, give your pavement a thorough cleaning:
- Remove all summer debris and dirt
- Clear leaves and organic matter
- Power wash if needed to prepare for sealcoating
- Ensure surfaces are completely dry before applying treatments
The Cost of Delaying September Maintenance
Failing to complete essential September maintenance can lead to exponential damage over winter. Small cracks left unsealed become large cracks and potholes by spring. The cost of September preventive maintenance is far less than emergency spring repairs.
