Why Sealcoating Matters in Sammamish

Sammamish lots deal with long wet seasons and shaded areas that stay damp longer, especially around tree-lined properties and residential communities. If the asphalt is still structurally sound, sealcoating helps slow oxidation and surface raveling. Crack sealing helps reduce water intrusion that can turn small cracking into bigger failures over time.

• Extend pavement life: slow surface aging from water, sun, and traffic
• Reduce water intrusion: seal active cracks before they spread and connect
• Improve curb appeal: darker finish, cleaner look for residents and visitors

Where Sealcoating Helps the Most in Sammamish

We commonly see faster wear in entrances, drive lanes, and turning zones, especially on busy community properties. In Sammamish that often includes:

• Retail and public parking areas near Sammamish Commons
• HOA and community lots in Pine Lake and Sahalee where traffic funnels through the same drive lanes daily
• Sites near Beaver Lake Park that see seasonal visitor spikes
• School/church lots where stop-and-go traffic and turning wear break down the surface faster

Stormwater and Environmental Care in Sammamish

Because stormwater flows directly to local waterways, we plan projects carefully around drains and runoff. If you want to see the City’s stormwater guidance and program info, these are useful references:

• Sammamish Public Works
• Storm and Surface Water Management (Stormwater)

We’ll flag drainage and low-spot issues during quoting, sealcoating protects asphalt, but it doesn’t solve ponding water.

After Sealcoating: Re-Striping (When Needed)

If your markings are faded, restriping is typically scheduled after the sealcoat has fully cured. That timing helps the paint bond properly and keeps the lines crisp.

Sammamish Sealcoating FAQs

How often should a parking lot be sealcoated?

Many lots benefit from sealcoating every 2–3 years depending on traffic and exposure. Entrances and drive lanes usually wear faster.

Does sealcoating fix cracks?

No. Cracks should be properly sealed first when the pavement condition supports it.

Can you phase work so the site stays usable?

Yes. We plan around access needs and keep routes open in phases when possible.
