Sierra Lawnmower Service

Keeping Fontana Productive Since 1987

In the Inland Empire, our landscapes demand a lot from us, and having equipment that starts on the first pull is the only way to keep up. Since 1987, Sierra Lawnmower Service has been the trusted partner for Fontana homeowners and garden enthusiasts alike. What began as a dedicated repair shop nearly four decades ago has become a local institution, built on a foundation of technical mastery and the kind of honest advice you only get from a neighbor who truly knows their craft.

As a locally owned and operated business for 39 years, we bring a level of "informed confidence" to every engine on our bench. Owner George Kao operates with a straightforward philosophy: tell the customer exactly what they need and get the gear back in the yard where it belongs. We understand that your outdoor power tools are an investment, and we treat them with the mechanical respect they deserve to ensure your Saturday morning projects go off without a hitch.

Mastery Over Every Engine

There is nothing more frustrating than getting up early to beat the heat, only to find your mower won’t turn over. Our technicians specialize in taking the guesswork out of engine failure. Whether it’s a stubborn ignition system or a gummed-up fuel line, we bring deep diagnostics to the table to ensure you aren't fighting your equipment while you're trying to work.

Our Specialized Maintenance and Repair Services:

• High-precision fuel system service and carburetor cleaning for reliable idling.
• Professional sharpening for mower blades, chainsaws, and hedge trimmer blades.
• Detailed engine diagnostics to identify underlying ignition and compression issues.
• Routine seasonal tune-ups including spark plug and air filter maintenance.
• Expert service for major brands including STIHL, Honda, ECHO, and Toro.

The Sierra Edge

What truly sets us apart is our 39-year legacy of straightforward, honest service. We don't just fix parts; we solve problems. Because we’ve worked on everything from Briggs & Stratton to Kawasaki and Kohler since the late 80s, we possess the institutional knowledge to troubleshoot makes and models that newer shops might turn away. Our focus is on getting you back to work quickly, utilizing a massive mental catalog of small engine fixes that only come with decades in the shop.

Whether you need a simple pull cord replacement or a more involved leaf blower repair, we prioritize efficient turnarounds. We know that in Fontana, the growing season is demanding, and our goal is to provide a smooth, dependable service that respects your time and your budget.

A Community Pillar

The vibe at Sierra Lawnmower Service is professional, grounded, and welcoming. We’ve been a staple of the Fontana community for decades because we prioritize the long-term health of your equipment over a quick transaction. Even if it's early on a Saturday morning, you’ll find a team that understands the technical nuances of outdoor power and is happy to help.

We look forward to ensuring everyone in our neighborhood has the professional-grade gear and dependable support they need to get the job done right. From basic maintenance to complex engine diagnostics, we are here to help you maintain your equipment with confidence.
