San Francisco wet winters work water into every small crack. Get your driveway or parking lot sealed now and stop the damage before it turns into a costly repair.

Asphalt sealcoating in San Francisco is a thin protective layer applied over an existing pavement surface, shielding it from UV rays, moisture, and fuel spills - most residential driveways take a single day from prep through final coat.
Think of it as a weather barrier for the pavement you already have. Without a seal, the binder that holds asphalt together slowly oxidizes and dries out, especially on driveways that sit in direct afternoon sun in neighborhoods like Bernal Heights or Noe Valley. Once the surface turns gray and brittle, cracks follow fast - and cracks let San Francisco rainy-season water in, season after season.
If your surface already has small cracks forming, you may also want to look at our asphalt crack sealing service before a full asphalt sealing - addressing those gaps first gives the sealant a clean surface to bond to and keeps the underlying base from getting wet.
When asphalt starts looking faded or chalky, the protective binder is oxidizing and drying out. In sunnier San Francisco microclimates - parts of the Mission, Bernal Heights, and Potrero Hill - this fading happens faster than most homeowners expect. A gray, brittle surface cracks much quicker than a sealed one.
Hairline cracks are the early warning that moisture is finding its way into the asphalt. Once water gets in, it works deeper - especially during San Francisco wet season from November through March. Sealing now, while cracks are still small, costs far less than waiting until the surface needs patching or replacement.
Drips from a vehicle parked in the same spot over time soften the asphalt binder and create soft spots that eventually pit and crack. Sealcoating creates a barrier that resists these stains. If you already see dark, soft-looking spots where a car parks regularly, those areas need to be treated before sealing begins.
Even if the surface looks okay, unsealed asphalt is quietly losing its resistance to moisture and UV damage. San Francisco averages around 20 inches of rain annually, most falling between November and April - an unsealed surface absorbs all of it. Staying on a regular maintenance schedule is the most cost-effective way to protect your pavement.
We handle sealcoating on residential driveways, commercial parking areas, and private roads throughout San Francisco. Every job starts with thorough prep work - surface cleaning, oil spot treatment, and proper crack filling - because a sealant applied over a dirty or damaged surface is a sealant that will peel. We also coordinate with our parking lot striping crew, since a freshly sealed surface wipes out all existing markings and re-striping is the final step that makes a commercial lot fully functional again.
We use squeegee application on steep San Francisco hillside driveways rather than spray, which prevents the sealant from running or pooling at the bottom of the grade. We also schedule around the weather - sealant applied before rain or in cold, damp air will not cure properly, so we watch the forecast and pick the right window, typically late summer through early fall when the marine layer pulls back.
Best for homeowners who want to extend driveway life and improve curb appeal before the rainy season or ahead of a property listing.
Best for property managers and business owners who need to protect a high-traffic asphalt surface and restore a professional appearance for tenants and customers.
Best for San Francisco hillside properties where standard spray application would cause pooling or thin spots - we adjust technique for the grade.
Best for property owners who want a recurring schedule so they are never surprised by a repair bill - a regular seal every two to three years keeps costs predictable.
San Francisco climate creates a double challenge for asphalt. The city signature marine layer keeps surfaces cool and damp for hours each day, which slows curing and gives moisture more time to work into unsealed pavement. At the same time, the Bay Area sits in an active seismic zone, and many neighborhoods - especially those built on fill like parts of the Marina - experience enough ground movement that cracks reappear faster than they would in a stable inland setting. A regular sealcoating schedule is one of the most practical things you can do to stay ahead of that cycle.
Customers in Daly City, CA and South San Francisco, CA face the same marine moisture conditions and benefit from the same late-summer scheduling window. The National Asphalt Pavement Association provides guidance on sealcoating standards and best practices that we follow on every job - you can learn more at asphaltpavement.org.
Describe your driveway or lot - approximate size, when it was last sealed, and any visible damage. We respond within one business day and schedule a site visit before providing a written estimate.
We walk the surface and assess crack depth, oil spots, and access conditions. This determines how much prep work is needed - prep is what separates a job that lasts from one that peels within a season.
The crew cleans, degreases, and fills cracks before any sealant goes down. We watch the forecast and only proceed when at least 48 hours of dry weather is confirmed - critical in San Francisco changing conditions.
We keep foot traffic off for 24 hours and vehicles off for 48 to 72 hours - longer if the weather is cool or overcast. Before we leave, we walk the job with you and give you a realistic timeline for the next application.
We schedule around the weather, apply the right technique for your grade, and give you a written estimate before any work begins. No pressure, no surprises.
(628) 895-9188We use squeegee application on steep San Francisco grades rather than spray, preventing pooling at the bottom and thin spots at the top. Most contractors use a one-method-fits-all approach - we adjust for how your driveway actually sits.
We hold an active California contractor license you can verify through the Contractors State License Board, plus liability insurance and workers compensation coverage. You are not taking a risk on an unverified crew.
We do not schedule sealcoating jobs without checking a multi-day forecast first. Applying sealant before rain or in cold, damp air means the product will not cure right - we only book jobs when the weather will cooperate for the full curing window.
You get a written quote that breaks out prep work, crack filling, and the sealcoating itself before we pick up a squeegee. No verbal ballparks, no add-on surprises after the job is done.
Every one of these points comes down to the same thing: work done right the first time lasts, and work done right the first time saves you money over the long run. That is the standard we hold ourselves to on every San Francisco sealcoating job.
A freshly sealed surface wipes out all existing markings - our striping crew repaints stalls, arrows, and accessible-parking symbols so your lot is fully functional again.
