Unattended Death & Odor Cleanup in San Mateo & Bay Area

---

 Unattended deaths and decomposition require immediate professional attention. The longer biological material remains, the more serious the contamination becomes. BioHazmat Solutions provides discreet, compassionate decomposition cleanup across San Mateo and the San Francisco Bay Area. We safely remove all biological material, fully decontaminate the area, and eliminate odors completely.

 Decomposition releases dangerous pathogens and gases that pose serious health risks to untrained individuals. Standard cleaning products are completely ineffective against decomposition contamination. Without proper protective equipment and hospital grade disinfectants you risk serious illness. Always call certified professionals immediately. 

 Our crew arrives in full protective equipment to assess and document the affected area. We contain the scene to prevent contamination spreading, safely remove all biological material, treat every surface with hospital grade EPA registered disinfectants, eliminate all odors using industrial equipment, repair any structural damage, and conduct a final inspection before leaving.

 Decomposition odor is one of the most difficult smells to eliminate and can penetrate deep into walls, floors, and structural materials. The smell of death comes from gases released as body tissue and fluids break down, so air fresheners and candles only cover it up for a short time. How long decomposition odor removal takes depends on how long the death went undiscovered and how far fluids spread into flooring, walls and other building materials. We use industrial grade ozone generators and hydroxyl machines to permanently eliminate odor at the molecular level. We don't just mask the smell — we destroy it completely so your property feels fresh and safe again.

 We understand that calls about unattended deaths and decomposition come during some of the most difficult moments a family can face. Our team works quietly, respectfully, and discreetly at all times. We can arrive in unmarked vehicles if requested. Your privacy and peace of mind are our absolute priority throughout the entire process. 

When a death goes unnoticed, the police and the county coroner or medical examiner handle the investigation and remove the deceased, but they do not clean the home. Once the property is released, the family, landlord or estate arranges after-death cleaning. A professional biohazard team removes contaminated materials, disinfects the area and deals with the odor so the home can be lived in, sold or rented again.

Decomposition cleanup requires immediate action — don't wait. BioHazmat Solutions is available 24 hours a day 7 days a week across San Mateo and the San Francisco Bay Area. Call 650-235-0729 now for fast, discreet, and professional decomposition and odor removal services. Families in the South Bay can also read about our unattended death cleanup in San Jose.

Sometimes a death is only discovered days or weeks later, after a neighbor notices a strong odor, flies at a window, or mail piling up. Even after the coroner has removed the person, body fluids can soak through a mattress, carpet and pad into the subfloor, and the odor can travel through vents into other rooms. This kind of after-death work is what many people call dead body cleanup. If a home has just been released after an undiscovered death, call us before anyone starts cleaning or throwing things away.

Every scene is different, but a typical job includes removing and bagging contaminated mattresses, furniture, carpet and pad; cutting out drywall, baseboards or subfloor where fluids have soaked in; cleaning and disinfecting every affected surface by hand with spraying, scrubbing and careful wipe-downs; sealing all biohazardous waste for proper disposal; and treating the remaining odor. When we finish, the room is ready for repairs, a move-in, or a sale.

There is no flat price, because no two scenes are alike. The cost of unattended death cleanup depends on how long the death went undiscovered, how far fluids traveled into flooring and walls, how many rooms are affected, how much material has to be removed, and how strong the odor is. We look at the space first and explain the scope and the cost before any work starts.

It may. Coverage depends on the homeowners, renters or landlord policy, and every policy is different. Call the insurance agent early, take photos before anything is moved, and keep every receipt and document. If you are handling an estate, the executor or the property owner usually makes the claim.

Whether you are a family member, a landlord, a property manager or an estate executor, call 650-235-0729, day or night, and we will walk you through the next steps.
