Rodent Proofing & Rat Exterminator Services in Corte Madera, CA

Corte Madera sits in one of the most convenient and desirable pockets of Marin County. With its easy access to Highway 101, nearby shopping centers, hillside neighborhoods, and marshland edges, it offers a mix of suburban comfort and natural surroundings.

That combination also creates steady pressure from rats and mice looking for food, water, and shelter. Homes near open space, greenbelts, and wooded hillsides often experience rodent activity at some point, even if the property is well maintained.

If rodents have found their way into your attic, crawlspace, garage, or walls, Done Right Rodent Proofing is here to help.

We are a Marin County based, family owned rodent exclusion company serving Corte Madera and surrounding communities. Our work goes beyond trapping and baiting. We identify how rodents are getting into the structure and permanently seal those access points so they cannot return.

The Rodent Pressure in Corte Madera

Corte Madera’s location creates a unique mix of rodent activity.

On one side, you have marshland and open space corridors that allow rodents to travel freely through natural habitat. On the other side, you have dense residential neighborhoods, apartment complexes, and commercial areas that provide steady food sources.

This combination makes it easy for rodents to move between wild areas and homes without being noticed.

We commonly see activity in:

• Hillside homes with tree coverage
• Properties near marsh edges and drainage areas
• Older homes with crawlspaces and vented foundations
• Townhomes and condos with shared walls and utility access points
• Garages and storage areas with frequent door access

Roof rats are especially common in Corte Madera because they travel easily through trees, fences, and overhead structures. Norway rats tend to stay closer to ground level, moving through crawlspaces and foundation gaps. Mice can spread quickly through extremely small openings between walls and utility lines.

What Homeowners Usually Notice First

Rodent issues in Corte Madera often start quietly.

Most homeowners don’t see rodents directly at first. Instead, they notice small warning signs such as:

• Light scratching sounds in ceilings or walls at night
• Droppings in garages or storage areas
• Chewed packaging or stored belongings
• Unusual odors coming from hidden spaces
• Pet behavior focused on specific walls or corners
• Occasional noises in crawlspaces or beneath flooring

Because many homes in Corte Madera are surrounded by landscaping, trees, or shared property spaces, rodent activity can develop gradually before becoming obvious.

How Rodents Get Into Corte Madera Homes

Rodents rarely enter through one obvious opening. In most cases, it is a combination of small vulnerabilities.

Roof rats often use tree branches, fences, and rooflines to access attic vents and gaps along the roof edge.

Norway rats typically enter through crawlspace vents, foundation cracks, or openings around plumbing and utility lines.

Mice can move through extremely small gaps and often travel between shared structural spaces in townhomes or attached housing.

We frequently find that multiple entry points exist at the same time, which is why sealing only one gap rarely solves the problem.

Our Rodent Control Approach

Every Corte Madera project begins with a full inspection of the structure.

We look at both the interior and exterior of the property, including areas that are often overlooked, such as:

• Rooflines and attic vents
• Crawlspaces and subfloor areas
• Garage interiors and door seals
• Foundation lines and drainage points
• Utility entry locations
• Landscaping that touches the structure

Once we identify how rodents are entering, we permanently seal those access points using construction grade materials designed to withstand rodent pressure.

This includes:

• Steel mesh and screening
• Metal flashing and custom fittings
• Concrete patching for foundation gaps
• Exclusion-related wood replacement where needed
• Reinforced vent protection systems

We do not use quick fixes like foam or soft fill materials that rodents can chew through or displace.

After the structure is sealed, we place mechanical traps in non-living areas such as attics, garages, and crawlspaces to remove any remaining rodents inside.

We return on a schedule to monitor activity until the property is fully cleared.

Why We Avoid Poison-Based Treatments

In communities like Corte Madera, poison often creates more problems than it solves.

Rodents may die inside walls, ceilings, or crawlspaces where removal is difficult. This can lead to odor issues and secondary pest activity.

Even more importantly, poison does nothing to stop new rodents from entering if access points remain open.

Our approach focuses on sealing the structure first so rodents cannot keep coming back.
