Water Moving Down a Slope
Describe where runoff crosses the site and where it collects. Collection placement should account for the water route and the areas you want to protect.

From a wet yard in Novato to moisture beneath a Mill Valley home, start with the way water moves through your property. Discuss French drains, sump pumps and coordinated moisture control across our Marin County service communities.
Water management in Marin County starts with the actual site. A sloped lot, an established garden or a narrow foundation-side access route can change where collection and piping can be placed. A low area may need a different discharge approach from a property with a workable gravity outlet.
Drainage & Moisture Control Inc. provides drainage and moisture control services for Marin County property owners. We review the water concerns, available access, existing features and potential discharge route before defining the proposed work.
The aim is to coordinate the system around the property, not to select a drain from a symptom alone. Tell us where water appears, when it happens and whether earlier drainage work is already in place.
Share the pattern, location and timing of the problem so the collection and discharge options can be discussed.
Describe where runoff crosses the site and where it collects. Collection placement should account for the water route and the areas you want to protect.
A wet area near the foundation needs review of surface runoff, underground moisture and the available outlet. A French drain is one option, not an automatic answer.
Moisture in a basement or crawlspace may require coordinated collection, pumping, barriers or waterproofing work after the source is assessed.
Different components solve different parts of the water problem. Explore the service pages for more detail.
Collect underground water along a planned trench with perforated piping and drainage materials. Discuss the collection route and outlet for your Marin property.
Explore service ↗Move water from a basin when the available site cannot rely on gravity discharge alone. Pump placement and piping need to be planned together.
Explore service ↗Review underground collection and transport where water accumulates or needs to be directed through buried components.
Explore service ↗Carry collected water between drainage components and a planned destination. Connections and the route matter as much as the line itself.
Explore service ↗Discuss moisture entry, drainage and below-grade protection around the actual affected areas of your home.
Explore service ↗Review ground moisture, barrier coverage and related water management needs beneath the home.

Whether the concern is beside the foundation, beneath the home or in an outdoor low area, share the conditions you are seeing. Access and discharge options can differ from one property to the next.
Ask About My Location
Our published portfolio includes a French drain project identified as Novato. Visit that project page to explore the company’s existing local work and its project photographs.
Project details help you ask better questions about collection materials, installation access and the route water takes through a system. Your own proposed work should still be based on your property’s conditions.
Share your Marin community, the affected areas and what changes during rain.
Review where water can be collected, how it can move and the available outlet.
Discuss excavation, existing surfaces and any related work included in the estimate.
Ask about scheduling and the details needed for a property-specific recommendation.
Discuss the conditions and access that matter for the work at your Marin address.
Discuss My Marin ProjectThese communities are part of our established Marin County coverage. Contact us with your address and water concerns to discuss availability and the project needs.
Discuss the slope, collection points, existing features and discharge options. The route should be reviewed for the actual property before deciding which drain components are appropriate.
A French drain collects water along a below-ground route. A sump pump moves water from a basin. Some sites need both; others can use a gravity outlet. Start with collection and discharge needs rather than choosing equipment first.
Yes. Ground vapor and standing water are different concerns. Barrier coverage, drainage and any pumping should be reviewed as related parts of the scope where appropriate.
Your address, where water appears, its timing and any existing drains or earlier work. Photos of the affected areas and access can help explain the concern.
Share any plans or photographs of the existing system. Its route, condition and outlet need to be reviewed before deciding whether it can support the proposed work.
Tell us about gates, paths, landscaping and the space beside the foundation. Access can affect the proposed installation route and how materials are brought to the work area.
Call (415) 226-5888 or (650) 609-0030, or email drainagemoisturecontrol@gmail.com. Share your address and a brief description of the drainage concern.
Start with the location and the water concern. Let’s discuss the next step.
