Expert Drainage Solutions in Sonoma County, CA

Poor drainage is a real problem for Sonoma County properties. The county sees most of its rainfall between November and March, and that concentrated wet season puts heavy pressure on yards, driveways, and foundations. Sloped lots, clay-heavy soils, and fire-scarred hillsides can push runoff directly toward structures. Marvel Grading & Paving assesses each property's grade, soil type, and existing water flow before recommending a fix. We regrade land surfaces to redirect water away from buildings, install swales to channel runoff safely, and add French drains where subsurface water is the issue. Every solution is built around your specific site, not a one-size-fits-all approach. Properties across Sonoma County, from flat valley parcels to hillside lots, face different drainage challenges. We work with the land you have to move water where it belongs. If standing water, soggy soil, or erosion is affecting your property, contact Marvel Grading & Paving to schedule a site assessment.

I have used Marvel Grading & Paving for multiple driveway paving projects including a large 10,000+ sq ft complete demolition and new paving project. Along with high quality on the initial job, the most impressive thing is that the owner stands by the company's work. They have returned a few times to do minor repairs and seasonal sealing at no extra charge! You don't get that kind of service too much anymore.

We've had Marvel Grading & Paving come out for several asphalt project and honestly, we couldn't be happier. From our very first call, they've been friendly, responsive, and make the whole process easy to understand. No pushy sales tactics, just honest answers to our questions. Their pricing was also really fair, definitely one of the better quotes we got. And the work itself turned out great! You can tell these guys care about doing a good job, not just getting in and out. We'll definitely be calling them again for any future projects and would recommend them to anyone nearby who needs paving work done. Thanks again to the whole team!

I've had Richard and Marvel up to our place to do work multiple times. There's a reason why! He started by repaving my badly degraded circular driveway when I bought the place, several years ago. It was very professional and still looks great! Since then, he's come twice and seal coated the asphalt, repaired and seal coated a quarter mile of our private road leading to our house and repaired several deficiencies we had. Only one time did I use another person to seal coat our driveway - and it was a disaster. I had to wait four years for the inferior product to peel off before I brought Marvel up again to do it on a more permanent basis. Can't say enough good about these guys. They even clean everything up and leave it spotless. Quality work. Most of our neighbors now use his services as well.
