Crawl Space and Basement Cleaning Services Serving the New Jersey Area & Eastern Pennsylvania

A dirty crawl space or basement is not just unpleasant, it is a health problem sitting under your house. Old debris, pest droppings, dead animals, mold, and damp all end up affecting the air in the rooms above, because so much of your home’s air comes up from below. Cleaning it out properly is the first step to a healthier house, and it is usually where the rest of the work begins.
Our crews have been cleaning crawl spaces and basements across New Jersey and Eastern Pennsylvania for 33 years. We do the job thoroughly, with the equipment and the know-how to leave the space genuinely clean and sanitary, not just tidied up.

What We Remove and Clean Out

• Old debris and trash left behind by past owners or contractors
• Wet, moldy, or contaminated insulation
• Pest droppings, urine, and nesting material
• Dead animals and the mess they leave
• General dirt, buildup, and anything else that does not belong down there

Once the space is cleared out, we clean and sanitize it so it is actually hygienic, not just empty.

Why a Clean Crawl Space or Basement Matters

A contaminated crawl space means contaminated air in the rooms above it. Pest droppings and urine carry bacteria and toxins, and the scent they leave draws more pests right back to the same spot. Moisture and mold spread if they are left alone, and a dead animal will make the whole floor above smell until it is removed. Cleaning the space out deals with all of it at once and takes away what was causing the problem.

Our Cleaning Process

1. Free inspection. We take a look at the space, see how much is down there and what we are dealing with, and give you an honest rundown.
2. Clear out the waste. Debris, trash, droppings, nesting material, and any dead animals come out first.
3. Remove contaminated insulation. Insulation that is wet, moldy, or full of droppings gets removed rather than left to keep contaminating the space.
4. Clean and sanitize. We clean the space down and sanitize it to kill bacteria and the scent that keeps pests coming back.
5. Point out the source. We show you what let the space get dirty in the first place, whether that is moisture, open entry points, or failing insulation, and what it takes to keep it clean.
6. Walk it with you. We show you the finished space so you can see it is genuinely clean.

Cleaning Is Step One

A clean crawl space does not stay clean if the reason it got dirty is still there. Standing water, open entry points, and failing insulation will bring the mess right back. Once the space is clean we can seal it, insulate it, add a vapor barrier, or rodent-proof the house so it stays that way. We will lay out your options at the visit, with no pressure to take on more than you want.

Benefits of a Professional Cleaning

Healthier air in the whole house

Clean out the source down below and the air in the rooms above gets cleaner and less musty.

Fewer pests

Removing droppings, nests, and the scent that marks the territory takes away what keeps drawing pests back.

A space you can actually use

A clean, dry basement or crawl space is usable again, for storage or just for peace of mind.

A clean start for insulation or encapsulation

Any insulation, vapor barrier, or encapsulation work goes better on a clean space, so cleaning is the natural first step.

Frequently Asked Questions

What does crawl space cleaning include?
We clear out debris, trash, pest droppings, nesting material, dead animals, and contaminated insulation, then clean and sanitize the space. We also point out what caused the mess so it can be dealt with.
How do I know if my crawl space or basement needs cleaning?
Common signs are a musty or foul smell in the house, droppings or nesting material, a dead-animal odor, visible mold, or years of debris and old insulation piling up down there.
Is it safe to clean a crawl space myself?
Pest waste and mold are genuine health hazards, and a crawl space is a tight, awkward space to work in. It is worth having it done professionally, with the right equipment and protection.
Do you remove dead animals?
Yes. We remove dead animals and the waste around them, and we sanitize the area so the smell and the health hazard are gone.
Will cleaning get rid of the smell in my house?
Usually, yes, if the source is down in the crawl space or basement. Clearing out the waste and sanitizing the space removes what was causing the smell.
Do you offer free estimates?
Yes. Every job starts with a free inspection, no obligation, and an exact price before any work starts. Call 800-682-1602 to set it up.
