Before & After Photos

This homeowner in Holmdel, NJ had a problem with flying squirrels in his attic. Flying squirrels, just like Eastern Grey Squirrels, are rodents. However, we don’t often see them because they are nocturnal. Homeowners generally realize that they have a flying squirrel infestation when they hear animal noises in the attic during the night once these little critters become active. If you happen to see one of these strange-looking squirrels, they are no longer than 10 inches, including their flat tail, and have large black-as-coal eyes. These animals don’t actually fly like birds or bats (the only winged mammal that can actually fly). But these squirrels can glide like a hawk — leaping into space and flattening their fur carpet bodies to glide from one tree to the next (or sometimes your roof where they find a way to access your attic).  

The homeowner had the entry points sealed, and contacted Cowleys to take care of the rest. These squirrels make their presence known as most home-invading nuisance wildlife — by leaving a path of destruction — often gnaw marks and always stains and odors from their urine and feces. Flying squirrel feces looks like bat guano and can cause some confusion about the type of wildlife infestation. These particular pests tend to do their business in the same spots.  Over time, their waste can seep through and stain the ceiling underneath. Like all wildlife, they can bring parasites and tics into your home, and their droppings, once they dry out, release disease-transmitting airborne particles. Needless to say, wildlife taking up residence inside your home is a serious health hazard.

Cowleys was called in to clean, sanitize, and deodorize the attic. Wearing proper protective equipment and masks, we removed the debris and the soiled insulation and hepa-vacuumed the entire attic space, which was a bona fide biohazard when we had first arrived. After making the attic safe, we installed 10” of our blown-in TAP cellulose insulation. Cowleys is a licensed installer of TAP Pest Control Insulation. TAP stands for its three key properties — Thermal, Acoustical, and Pest Control. This insulation not only offers superior thermal and acoustical (sound-deadening) properties but has a pest control component as well. The paper fibers are treated with a borate solution that is harmless to people, but lethal to many insects including ants, beetles, and termites. 

By the time we were finished, this Holmdel residence looked like it had a brand new attic with top-quality insulation. This was a particularly rewarding job for all of us on the installation team. It’s a great feeling to transform an attic that was destroyed by invading wildlife into a clean, beautiful, functional space.

Previously, our Little Rascals Nuisance Wildlife Removal team and safely and successfully removed a large number of bats that had been living in this homeowners' attic. The only downside was that the bats left behind a toxic mess of bat guano (bat feces). 

First, we carefully disinfected the entire attic and removed all the contaminated insulation. Afterward, we added approximately 10 inches of TruSoft blown-in cellulose insulation! TruSoft blown-in cellulose insulation has a higher R-value than standard fiberglass insulation, has the highest Class-1 fire safety rating, is resistant to mold and pests, and is eco-friendly! Blown-in cellulose insulation maximizes home comfort and optimizes energy usage for year-round peace and savings.

I was sent to Holmdel, NJ to help homeowners who were dealing with a mouse infestation in the void above their basement ceiling. After finishing up exercising on their basement treadmill,  the homeowners heard some strange noises above their heads — the scratching and scurrying noises of mice above their heads. Mice prefer to stay away from well-lit areas and stay in out-of-the way places like wall voids and above ceilings where they can come and go and move around the house as they please. When things are quiet, these sounds tend to amplify, and often, homeowners think that they are dealing with a much larger problem like squirrels or even raccoons. Of course, no homeowner should ever think that it’s “just mice.” Mice and their urine and droppings can contaminate food and counter tops. Like any wildlife, they are a health risk to a home’s occupants.

Needless to say, the homeowners were right. Mice had entered their living space from outside. Mice usually enter homes around gaps and cracks in the foundation, and I began my inspection in the basement, first popping out some tiles near where they had heard the unwanted visitors so I could get a better look. There were some mice droppings on to of the ceiling tile. I immediately saw how the rodents were gaining access. There was some daylight coming from a small opening on the outside wall. There was a hole drilled through the foundation, possibly for a exterior water spigot. However, nothing was ever installed and the hole was never sealed. Mice exploited the opening and came into the home.  Mice only need a hole about the size of a dime to squeeze through. These rodents are even smaller than they look because of all their fur. They have no collarbone, so if they can stick their head through an opening, the body will follow.

I always carry disinfectant and a hepa vacuum with me. I first sprayed the the droppings before cleaning them up. It is dangerous to disturb dry droppings because microscopic particles containing dangerous pathogens like potentially fatal hantavirus are released into the air.   

Preventing entry is key to rodent control. I stuffed the entry points with copper mesh that rodents are unable to chew through. Finally, I secured a rodent bait box on the home’s exterior near the hole. The combination of these strategies will soon put an end to the mouse problem for these homeowners. 

Recently, a momma raccoon decided to take up residence in an elementary school in Lincroft, NJ. She set up a nesting area above the school’s drop ceiling for herself and her three babies. Needless to say, school administrators were none-too-pleased with this wildlife problem. Raccoons are large aggressive animals that also happen to be New Jersey’s primary rabies vector. Mother raccoons can be particularly aggressive if they feel that someone is threatening their kits. In short, raccoons, in and around any structure, especially a school where there are curious little kids looking for trouble, is a dangerous situation. I was told that the raccoon noises were becoming a serious distraction to both students and faculty. In addition, raccoons can cause extensive property damage. With this infestation, as often happens, the raccoons ruined much of the insulation above the drop ceiling. They tear up the soft, cushiony material for nesting and it becomes a sponge for their wastes. The school will handle the insulation removal and replacement later on.  And it’s not just the animals that pose a danger. Wildlife urine and waste particles, which can become airborne, can contain dangerous pathogens.  

Upon arrival, as with any wildfire infestation, I inspected the building to to determine how the raccoon gained access to the building. Usually, with large animals, the entry points aren’t too subtle. Here, I immediately saw that the raccoon ripped out one of the flimsy air vent screens. Often, standard air vent screens used by contractors are not sturdy enough to withstand a wildlife “break-in.” They are simply not made with wildlife intrusions in mind and standard vent covers are no match for a determined raccoon. There animals are not only strong intelligent animals, but they also have human-like five-fingered front paws that are extremely dexterous. They have been known to open doors and screw the lids off cans! 

It was important to trap these raccoons, and get the job done quickly. We placed four baited traps on the roof of the school in strategic locations based on their activity. The mother raccoon must leave the nest in order to forage for food for herself and her babies. Two days later, “momma” was successfully captured. We then proceeded to retrieve the helpless babies, removing them one by one, and reunited them with their worried mother. One thing we don’t do is split up happy raccoon families! We relocated the family to a safe area far away from human habitats. Finally, to prevent future re-infestations, we fortified all of these potential entry points by screening off the eight roof vents with 1/4-in, galvanized hardware. Raccoons or squirrels will not be able to gain access into the building through these heavy-duty vents. This Lincroft school that should not have to worry about another wildlife infestation anytime soon! 

The Cowleys home improvement crew was sent to a home in Colts Neck to remodel the homeowner’s outdoor access to his crawl space. His old crawl space entry was cumbersome to open and close, and even worse, it provided virtually no protection from the outdoor elements. Whenever it rained, the current crawl space access allowed a stream of water to rush inside. The homeowner was concerned about standing water in the basement and the problems it could cause, and rightly so. Standing water in the crawl space is an open invitation for mold growth and is an attractant for mosquitoes, other insects, and all sorts of wildlife.

We wanted a crawl space access that was easy to use, blocked rainwater from entering, and provided protection from the outdoor elements. To meet these objectives, we replaced the entry cover with one of our Everlast doors. These Everlast vent covers completely block outside air and moisture from entering the crawl space. They can be installed against wood framing or masonry, work exceptionally well, and are aesthetically pleasing. Made with a hard durable plastic, they stand up to the worst weather conditions, and are completely maintenance free. They should never rot, warp, or crack and they never need to be painted. From out experience, they are virtually indestructible. Also, if you or a repair person needs crawl space access, they are easy to open. All you need to do is twist a few easy-to-grip knobs, and you’re in! 

Given this homeowner’s water issues, we wanted to have a second barrier to prevent water entry. We decided to install a product manufactured by the Bilco Company, which makes a variety of USA-made specialized doors and other specialty access products for the building industry, including the StakWEL window well. 

What’s a window well? And why would Cowleys want to install a window well around a crawl space door? Glad you asked!

Most basements have windows, especially finished basements since it’s nice to have some natural lighting and a way to let in outdoor air. Windows installed in basements that are mostly below-grade require window wells — those semi-circular “dig-outs” you find on the basement window’s exterior. This well needs to be supported by some materials or it will eventually collapse. 

Window wells help prevent water penetration around the window framing and window damage (Basement windows are prone to damage since they are at or near ground level.). Window wells also allow for emergency egress out of the basement. This is important because most local building codes require basement windows to provide emergency egress, in which case, the well needs a built-in steps or ladder. Window wells should also have covers to keep out leaves and debris and help prevent water and snow from collecting inside the well.

We decided to install a window well around this crawl space door for many of the same reasons that a homeowner would want to install one around their basement window. This homeowner was having a serious water intrusion problem whenever it rained. The safest course of action was to give him a second barrier in addition to the Everlast door, and the StakWEL window well fit the bill perfectly. It’s is made out of a tough corrosion-resistant high density polyethylene, and it’s modular, which greatly simplified installation. As a bonus, these wells have a grip-step design so you don’t have to have the agility of a mountain climber to enter and exit the crawl space access area. The window well also has an optional cover for extra protection against the elements. 

After we were done, the remodel of this crawl space access looked great, and we are confident that his water issues will finally be over. The homeowner was quite pleased, and he said that he’d let us know after the first heavy rain how his crawl space was holding up. We expect to here nothing but good news!
