Why seal cracks
Every crack is an opening for water — rain, irrigation runoff, sprinkler overspray — and for wind-blown sand. Water softens the base, especially on damp valley ground. Sand packs the crack so it can't close in summer heat, and the edges break down. Winter nights still freeze here, which pries cracks wider. Sealing stops all of that early.
How we do it
- Clean out weeds, sand and loose material; blow clean.
- Rout where needed.
- Hot-pour sealant that stays flexible.
- Finish flush or slightly banded.
Fixes
Individual cracks about 1/4" to 1" wide along edges, seams or across the drive.
Doesn't fix
Alligator cracking, potholes or sunken areas — those need repair.
Spring and fall are the best times. For lots and shared lanes, crack sealing every year or two is the cheapest maintenance there is.
Common questions
When should I seal cracks?
Spring or fall, when cracks are mid-width.
How long does sealant last?

It helps short-term but often shrinks or pops out.
