The Hoarding Cleanup Guide: Everything You Need To Know About Dealing With Hoarders

Cleaning up after hoarding should be done slowly, methodically, and with sensitivity — it’s as much an emotional process as a physical one. Start by addressing safety hazards and obvious trash, work room by room from top to bottom (beginning with a low-stakes room like the bathroom), set aside a staging area to sort what’s kept, donated, or discarded, and never throw away a hoarder’s possessions by surprise. Because hoarding is a recognized mental-health condition, the most important step is encouraging the person to work with a mental health professional; cleanup is usually the final stage of help, not the first. For severe cases involving biohazards, a professional hoarding cleanup service is the safest option.

Dealing with hoarding is difficult for everyone involved. Someone who has begun hoarding may be unwilling to accept there’s a problem, even when their possessions are taking over their home and making it unsafe. This delicate situation calls for a sensitive, careful approach to avoid doing more harm than good.

The first step is recognizing when hoarding has become a problem. Many people keep clutter and hang onto things longer than necessary, but sometimes that sentimental attachment or sense of “I might need it one day” gets out of control, until everything feels important and impossible to discard.

What is hoarding?

According to the Mayo Clinic, hoarding disorder is “a persistent difficulty discarding or parting with possessions because of a perceived need to save them.” Many people who hoard keep items most would consider worthless — old newspapers, plastic bags, trash, clothing. Unlike a true collection, which is usually curated and organized, hoarded items are often kept in disarray and spill into the living space.

The difference between clutter and hoarding

Clutter is a common complaint — a stack of old magazines by the sofa, a few more shirts than fit in the closet. But there are ways to tell when clutter has crossed into hoarding.

It’s important to address hoarding early, because it can quickly create an unsafe living environment — clean homes are healthy homes, and a hoarder’s home can become a magnet for pests and bacteria.

Often the first sign is being unable to use parts of the home as intended — a sofa you can’t sit on because it’s piled with papers, or stairs you can barely climb. As the behavior continues, the accumulation worsens until whole rooms become inaccessible.

Generally, if your home is messy but you can tidy it when visitors come, it may be time to declutter — but it isn’t hoarding.

What are the reasons for hoarding?

Hoarding disorder was recognized as a distinct mental health condition in the DSM-5 in 2013. Despite its prominence on TV shows like Hoarders, it’s estimated to affect only about 2 to 5 percent of the population.

The causes range from generalized anxiety to a traumatic event. People who hoard keep possessions for the same reasons anyone does — sentimental attachment, or a belief they’re useful or necessary — but for them that attachment or sense of need becomes misplaced.

A fear of not having something when it’s needed can also trigger hoarding, sometimes rooted in the past (such as not having had enough, or a single trauma like a house fire). Sometimes there’s no identifiable triggering event at all.

The 5 levels of hoarding

Hoarding is often classified into five levels, depending on severity:

Stage 1: Considered heavily cluttered rather than hoarding. All rooms are passable and the house is still clean and safe.

Stage 2: Possessions are starting to take over. One or two rooms are hard to navigate, odors may be present, mildew may appear in the kitchen and bathroom, and there may be pet waste. One exit may be unusable.

Stage 3: Only one bedroom and/or bathroom is usable, with limited living space. Dust and spoiled food have accumulated, the home has a strong odor, and clutter may be visible from outside.

Stage 4: Flea or lice infestations may be present, along with sewage backup and other unsafe conditions. Rotten food and pet damage are common.

Stage 5: The most severe level. The home has rodent infestations, the kitchen and bathroom are unusable, and human and pet waste may accumulate. Utilities may not work, and many areas are completely inaccessible.

When to have a hoarding intervention

If you suspect a friend or relative is hoarding, it’s better to address it sooner rather than later — but because hoarding is a disorder and can accompany other mental health conditions, approach the subject with sensitivity.

Encourage the person to see a mental health professional to address the root cause, and resist the temptation to surprise them by throwing things away. That’s more likely to intensify hoarding compulsions and make things worse. Cleaning a hoarder’s home is usually the final step of an intervention, not the first.

How to start a hoarding cleanup

A thorough clean matters because hoarding has serious health and safety consequences. Common dangers include:

• Increased fire and trip hazards
• Higher levels of indoor air pollutants
• Structural collapse
• Biohazards
• Pest infestations

Because letting go of possessions is hard, cleanup is best done slowly and methodically. Not everything should be thrown away — some items hold genuine sentimental value or are truly necessary, and keeping them is the right call.

Begin with hazardous materials like rotten food and pest infestations. If you’re dealing with biohazards, hire a professional cleaning company. Use appropriate protective equipment — gloves, masks, hard hats, and sturdy boots.

For a lot of rooms, hire a junk removal service or rent a dumpster bag to make disposing of trash, damaged items, and unwanted furniture easier.

An extreme cleanup can take days or even weeks without help. Give yourself plenty of time, and account for the emotional weight of the task. Large cleanups are hard on friends and family as well as the person hoarding, and you may be shocked at how bad things have gotten. Don’t feel you must work relentlessly to the finish — build in time for everyone’s emotional needs, stress, and anxiety. Our checklist for deep cleaning a property at your own pace has more ideas.

Professional hoarding specialists understand and are sympathetic to the physical and mental aspects of these cleanups. Depending on the scale of the work, hiring professional cleaners is often a worthwhile investment in everyone’s wellbeing.

Hoarding cleanup costs

Cost depends on the size of the property, the extent of the hoarding, and the materials that need removing. Expect to pay more for hazardous waste — mold, fungi, rotten food, and biohazards such as excrement, infestations, and dead animals.

Disposal of large items like furniture, flooring, and drywall can also be costly. For worst-case properties, cleanup and disposal could run to several thousand dollars, but always consult a hoarding cleaning service directly for a specific quote.

A hoarding removal service can help with all the factors involved, and may spot and handle hazards you hadn’t considered. What’s included varies, but usually covers creating a full inventory, sorting and disposing of belongings, and cleaning and disinfecting the property. Professional cleaners know the local rules for disposing of hazardous waste and the right steps for handling biohazards.

Hoarding cleanup tips

• Wear protective equipment at all times — heavy gloves, masks, eye covering, hard hats, sturdy boots — and keep a first aid kit on site
• Buy cleaning supplies in advance
• Make safety your first priority
• Evaluate each item to decide whether to keep, donate, or discard it
• Start with a small room — bathrooms are ideal, since there’s little of sentimental value to worry about
• Work top to bottom so you aren’t tracking dust through rooms you’ve already cleared

Cleaning supplies checklist

Have everything you need on hand before you start. If you find biohazards, you must call a professional company to dispose of them — it’s usually illegal to put hazardous materials in the trash. Check with your dumpster company or city sanitation department for how to correctly dispose of items like paint and old medications.

• Heavy-duty trash bags
• Buckets and mops
• Cleaning rags and sponges
• Broom and dustpan
• Vacuum cleaner
• All-purpose cleaners and disinfectants
• Pest repellent
• Empty boxes

Also bring any tools you might need — a stepladder, hand tools, a bright flashlight, and a shovel.

Your first priority is getting the home cleared and sanitized — not just for appearance, but because clean homes help you stay healthy. You can save money using general all-purpose cleaners and reusable rags for the first pass; afterward, dispose of any tools you can’t sanitize and use clean cloths and wipes to disinfect everything properly.

Hoarding cleaning checklist

Assess the situation and make a plan

Hoarding has many facets — you might face a single piled-high room or a whole house bursting at the seams. Walk through the property, assess what you’re dealing with, and make a plan. At the top of your concerns: an exit plan in case of fire or other hazards, and clearing common pathways to prevent trips and falls. Your safety comes first, so securing the property is task one.

Create a staging or sorting area

If you have outdoor space like a garden, lay down a tarp for staging. Otherwise, clear the largest or most central room early and use that. This is where you bring anything to keep, donate, or recycle, sorted into piles to review once the property is cleared.

Start small

The bathroom is one of the best places to start — there’s little of sentimental value, so it’s quick to empty and clean, and you’ll want a working bathroom and running water while you work.

Work from top to bottom

This applies to the property as a whole and to each room. After the bathroom, start with the room farthest from the exit. Within each room, clear possessions stacked on beds, tables, and furniture before tackling the floor.

Remove trash first

Out-of-control hoarding usually involves a lot of accumulated trash. Start by discarding anything that’s obviously garbage — it speeds up the job and gives an early sense of accomplishment.

Check for valuables in pockets and papers

People who hoard often lose track of where valuables are, so move cautiously. A stack of papers might be all junk mail — or hide a life insurance policy — and a valuable ring could be tucked in an old jeans pocket. Go through everything thoroughly before discarding.

Temporarily remove large furniture and appliances

If possible, clear each room completely as you work. Even furniture and appliances in good condition benefit from cleaning, and a fully clear room makes deep cleaning and checking for damage much easier.

Put “maybe” items in the staging area

You don’t have to decide on every item immediately. Once obvious trash and large items are out, move everything else to your staging area, then review the piles after the property is cleared to decide what to keep, donate, recycle, or trash. Organize the staging area by type of item rather than by room — it helps you spot duplicates so you keep only what’s necessary.

Carry out necessary repairs

In many hoarding properties the carpet is damaged beyond saving, but even if it looks fine, lift it to check the flooring underneath. Long-term water damage, mold, or rodent infestations can cause structural damage needing repair. Check flooring and drywall for stains or rot, and have a plumber and electrician inspect the pipes and wiring if you suspect they’re compromised. If a lot of repair work is needed, consider a post-construction cleanup to clear leftover dust and dirt.

Deep clean after clearing and repairing

Once the property is empty and repairs are done, deep clean with fresh equipment, starting from the top of each room. Take down light fixtures, wash the walls, and follow our spring cleaning guide to restore every room.

Moving on from hoarding

Clearing and cleaning the home is the first step, but afterward it’s important to stay supportive so the person doesn’t return to old patterns. Encourage good cleaning habits, make sure they have plenty of cleaning supplies, and continue working with a mental health professional on their ongoing recovery. Helping someone through a hoarding cleanup is difficult and intensive — but approached with patience and care, it isn’t impossible.
