Keeping Water and Sun Out
Sealcoating and crack filling are the two cheapest ways to make asphalt last in Southwest Louisiana. Cracks let rain into the base; sun dries out and grays the surface. Filling cracks keeps water out, and a sealcoat shields the surface. Neither fixes broken pavement, but together they slow down the aging of pavement that is still sound.
Crack filling first
Open cracks are cleaned, wider ones routed, and filled with a flexible hot-applied sealant that moves with the pavement. HomeGuide lists crack filling at about $0.50 to $3 per linear foot. Dry weather is best, when cracks are open and clean.
Then the sealcoat
After cracks are sealed and small failures patched, sealer goes on in even coats. HomeGuide puts driveway sealing at about $1 to $2 per square foot, with an average job near $600, and HomeAdvisor lists lot sealing at $0.15 to $0.30 per square foot.
Timing
New asphalt needs three to six months to cure first. After that, guides suggest resealing every 2 to 10 years depending on the product and climate; strong sun and heavy rain push toward the shorter end. Sealer needs dry pavement, temperatures roughly 50 to 95 degrees and dry hours to cure. HomeGuide lists 12 to 72 hours before driving.
Choosing a sealer
Coal tar sealers are durable but restricted in many areas over health and runoff concerns. Asphalt emulsion is generally considered the more environmentally friendly choice. We tell you what we will use.
Signs it is time
- Black has faded to gray
- Stones show at the surface
- Water soaks in instead of beading
- Fine cracks are appearing
Lots
On commercial lots, sealing covers the old lines, so we restripe afterward, including accessible spaces to the 2010 ADA Standards.
How long a sealcoat lasts
Sealcoat wears fastest in wheel paths and at turns. Driveways usually look good for a few years; busy lot entrances wear sooner. Resealing before the surface goes fully gray protects the asphalt underneath.
Value
HomeGuide puts the average driveway seal near $600, a fraction of resurfacing at $3 to $7 per square foot or replacement at $5 to $12 or more. That is why sealing sound asphalt is one of the best values in pavement care.
When not to seal
If a driveway has widespread alligator cracking, soft spots or potholes, sealing hides problems for a season. Repairs come first.
Crack filling on lots
On commercial lots, crack filling is done in sections before sealing and restriping, so traffic keeps moving.
Before and after storm season
The best time to fill cracks and seal is in dry weather before the wettest months, so water cannot get into the base when storms arrive.
Rubberized sealant
For working cracks that open and close with heat and moisture, a rubberized, hot-applied sealant stays bonded longer than cold pour fillers.
Driveways versus lots
On a driveway, sealing is a one-day job plus cure time. On a lot, it is done in sections with traffic routed around wet areas.

Cleaning
Dirt, debris and oil spots removed.
Crack filling
Cracks cleaned, routed where needed and sealed.
Small patches
