When something happens that you were never trained to handle on your own, Four Month Blood Cleanse is one call away in Daly City. Our crews arrive fast, work discreetly, and leave the property safe, sanitized, and restored.


Four Month Blood Cleanse is a fully licensed and insured Infectious Disease Decontamination company serving Daly City, CA and the surrounding area. Every technician on our crew is trained, background-checked, and certified to handle biological hazards safely β and to treat the people affected by them with dignity.
Our Daly City crew is local β not a subcontractor pulled from three states away. That means faster arrival times, familiarity with local disposal regulations, and a team that's actually invested in this community.
Beyond the technical side, our Daly City team understands that a biohazard call almost always comes during a stressful, sometimes traumatic moment. That's why every technician goes through communication training in addition to safety certification β so you get a crew that's skilled with equipment and calm with people.
Daly City customers deserve to know exactly what training and equipment a crew is bringing into their home or business. Here's the short version.

No two calls are identical, but most fall into a few categories. Here's a closer look at what our Daly City team handles on a regular basis.
When a death goes unnoticed for days or longer, biological material can affect flooring, subflooring, and even structural materials. Our Daly City crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in Daly City facing this kind of loss deserve a crew that works quickly and quietly. We coordinate with law enforcement when needed and complete cleanup once the scene has been released.
Hoarding jobs in Daly City often involve biological hazards hidden under clutter β mold, pest waste, and spoiled materials. We sort with care, separate salvageable items when asked, and sanitize the full property.
Raw sewage introduces serious pathogens into a Daly City home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in Daly City has been exposed to an infectious illness, we perform full surface and airborne decontamination using medical-grade disinfectants to reduce risk for anyone who uses the space next.
Former drug production sites in Daly City leave behind chemical residue that ordinary cleaning can't remove. Our specialized team tests, treats, and clears the property according to CA remediation standards.
A real person answers your call in Daly City β day or night β and starts dispatching a crew immediately.
We show up quickly and quietly β no branded trucks parked outside broadcasting what's happening.
Before any work begins, we explain the process, the timeline, and the cost β no surprises later.
Using hospital-grade disinfectants and proper PPE, we remove, clean, and sanitize every affected surface.
All biohazard waste is transported and disposed of through licensed facilities, with documentation provided for your records.
Biohazard incidents happen everywhere β homes, offices, vehicles, and public spaces. Here's how our Daly City team adapts to each one.

We work with Daly City property managers and municipal contacts to decontaminate shared spaces safely and get them back in service quickly.
We know the cost of Infectious Disease Decontamination services is a real concern. Here's what to expect when it comes to pricing, insurance, and paperwork.
If you have questions about how a specific insurance policy applies to your Daly City situation, mention it when you call β our dispatcher can often give you general guidance right away.
We know you're not just comparing prices β you're trusting someone to handle one of the hardest moments you'll deal with. Here's why Daly City residents choose us.
You'll know the cost before we begin. We work directly with insurance when possible to reduce your out-of-pocket expense, and we explain every charge in plain language.
Because we're locally positioned near Daly City, our average arrival time beats companies dispatching from farther away. That speed matters when biological hazards are involved.
We never discuss the details of a job outside what's necessary. Discretion is part of the service, not an upgrade you have to request.
Our team documents every step of the job to support your insurance claim, and we bill many major carriers directly to reduce your paperwork.
We don't consider a job finished until the space passes our own internal inspection standard, not just a quick visual check.
We treat every Daly City customer with the same patience and respect we'd want for our own families, from the first phone call to the final walkthrough.
