Unfinished basements are prime targets for rodents, with easy access through gaps, vents, pipes, and foundation cracks. Left unchecked, they can gnaw through insulation, destroy wiring, and nest in hidden areas, leading to costly repairs. We reinforce vulnerable spots by sealing cracks, blocking entry points, and installing rodent-proof barriers, such as RodeXit weatherstrips and heavy-duty sealants.

With specialized cleaning equipment and local experts who understand Bay Area environments, such as hillside homes in Oakland and coastal properties in Marin, we make sure your expectations are met with our unfinished basement cleaning service. Here’s our process:
We begin every project with a free inspection to determine the condition of your unfinished basement, and its infestation level. One of our rodent control professionals will walk through your house, starting with your basement, checking for entry points, signs of rodent activity, and any structural problems that might lead to bigger issues.
After examining your house, weโll create a quick, comprehensive analysis of our findings for your benefit. Weโll point out problematic areas, talk to you about what options you have for remediation and our rates, and give you our professional opinion on what steps to choose if we were in your shoes. If youโre still on the fence about whether to request a free inspection, consider these benefits:
Once the inspection is complete, weโll email you a Comprehensive Diagnostic Report (CDR). Its purpose is to document all problematic areas and surroundings, give you a detailed assessment of the severity of the issue, and offer transparency into our quote and process, the preparation involved, and the expected timeline for completion. This clarity can help you quickly decide how to move forward without any type of guesswork.
Once youโre ready to get started, our crew will begin to clean up and remove the mess. To do so, weโll carefully move and organize any rugs, furniture, and appliances, so we can properly clean and vacuum the floors. Additionally, weโll ensure all shelves are clean and wiped down to remove any built-up grime and accumulated dust. Grease marks along any door or wall are also cleaned. Lastly, weโll check cabinets, closets, fixtures, and any storage nooks in your basement to ensure nothing is missed.
Once everything is cleared, weโll sanitize and decontaminate your basement to eliminate any leftover bacteria, rodent pheromones, contaminated residue, and harmful pathogens that remain. To do so, weโll use specialized cleaning solutions and products, such as Nisus Bioesque, that are specifically designed for rodent-infested areas and hard-to-reach spaces such as in insulation, under non-movable appliances (e.g., a water heater), and in obscure corners. For the Bay Areaโs damp coastal climate, we also use eco-friendly, mold-inhibiting agents to avoid any future mold growth and asbestos. This will help create a healthy living environment for your family to enjoy happy memories for the future.
After your unfinished basement is cleaned, vacuumed, and sanitized, we seal, reinforce, and prevent future damage to the area. Increasing rodent activity can quickly create worsening conditions that threaten any type of wall or floor, especially in unfinished basements.
At Alley Cat, we use proven, high-quality exclusion methods to protect your home long-term:
From having worked on 11,000+ homes across San Francisco and the East Bay with a 97% satisfaction rating, Alley Cat remains the choice you can trust for your unfinished basement cleaning service.
To catch any remaining rats or mice, we discreetly set traps in your unfinished basement near entryways and under sources of warmth (e.g., water heater). Our team will then return a few weeks later to check and replace these traps, ensuring the job is finished and no further infestation occurs.
Finally, after we clean, vacuum, sanitize, and seal all potential entry points around the walls and floors, itโs time to handle the final tasks for your house. Before we leave, we focus on moving and organizing all the things in your home we moved back where they were. We also do a required โsweepโ โ checking for any last-minute mistake, areas not vacuumed, leftover cobwebs, and appliances not moved back to make sure we close out the project on a great note. Then, after itโs cleaned, we dispose of all the contaminated items in a moving dumpster, and bring everything to the dumpโleaving your basement and any kind of fixtures clean and organized.
At Alley Cat, we take pride in our people and in tailoring our cleaning services to your unique needs. We aim to provide fully transparent answers to your questions, and we are ready to take on any project, of any size. Over the years, by emphasizing communication and consistent follow-up, weโve made sure every one of our clients feels confident from start to finish.

I had rats in my basement and guestroom. I called Alley Cat and Milo came and did a thorough examination of my entire house and gave a quote. Augusto and his crew were incredibly thorough. They also pulled out my stove and dishwasher (neither works) and found rats had chewed through from the basement to nest behind those appliances. They cleaned, sanitized and left snap traps. A full days work for four men. I also bought a 3year trapping agreement (they come when called) as I also had rats 5 or 7 years ago. Great job.
Yes, cleaning an unfinished basement is essential to prevent dust buildup, mold, and pests, but doing it wrong can expose you to serious health risks. Using bleach and paper towels on rodent-contaminated areas can aerosolize harmful particles, increasing the risk of inhaling contaminants like hantavirus and salmonella.
A good strategy is to wear full-body disposable gear, gloves, and an N95 mask. Avoid sweeping, which stirs up dangerous particlesโinstead, use a HEPA-filter vacuum and damp cleaning methods. Sanitize surfaces with EPA-approved disinfectants, not household cleaners, and seal cracks, vents, and gaps to block rodent entry.
With the Bay Areaโs fluctuating moisture levels, basements can quickly become breeding grounds for mold and rodents. A proper deep clean improves air quality, prevents damage, and protects your home. If contamination is present, hiring a professional basement cleaning service ensures a safe, thorough job.
Start by removing all clutter, junk, and debris, as pests thrive in undisturbed piles of materials. Instead of dry sweeping, which kicks up harmful dust and contaminants, use a commercial-grade HEPA-filter vacuum to trap fine particles, dirt, allergens, and rodent waste. Sanitization is key, especially in older basements. Instead of household cleaners, choose quaternary ammonium disinfectants or hydrogen peroxide-based solutions, which kill bacteria, mold spores, and lingering pathogens without having to deal with toxic fumes.
To prevent future issues, seal foundation cracks with steel wool and sealant, apply high-performance vapor barriers, and use rodent-proof materials on doors or access points. Deep cleaning an old unfinished basement requires thorough cleaning, decontamination, and preventative measures. Our expert residential specialists can keep your space clean. Hire us today!
Clean an unfinished concrete basement floor by first vacuuming away loose dust, dirt, and debris. Next, use a mild or specially formulated wash solution for concrete, scrubbing the floor with a stiff brush. Wash and rinse the area thoroughly, then dry it with fans or open windows to ensure moisture doesnโt linger, especially on the ceiling or cleaned floors.
This cleaning process is particularly helpful for houses in Oakland, Berkeley, or San Mateo, where humidity can turn small cracks into bigger problems. After itโs cleaned, sealing the floor can add longer protection, keeping your basement a safe place for storage, laundry, or even an office space. By investing in our services, you can take care of each item in your basement every day.
Start cleaning a dirty, dusty basement by first removing clutter, furniture, tools, and all other types of important items. We recommend vacuuming all concrete floors and surfaces with a HEPA-filtered vacuum, and wiping all walls, shelves, and furniture in case there’s a rodent infestation in your home.
Focus on corners, cabinets, and hidden areas where dirt, dust, and cobwebs accumulate. It helps to wear protective gear (e.g., masks) while cleaning to avoid inhaling contaminated particles, and use your phone to take pictures of bad, hazardous areas.
In areas such as Daly City, San Bruno, or Hayward, where moisture can build up:
