Before & After Photos

Recently, our crawl space specialists completed an upgrade for a home in Point Pleasant, NJ. The homeowner thought that after a recent heavy rainstorm he better check his crawl space for water. It was a good thing he did. The crawl space had stagnant water along with high humidity levels. He was concerned, and rightly so, that mold could develop. Moisture build-up in crawl spaces creates an ideal environment for mold growth. When hidden mold forms in the non-living spaces of homes like crawl spaces, basements, and attics, airborne spores circulate throughout the entire home adversely affecting air quality for the home’s occupants, and those sensitive to mold can develop respiratory issues. Excess moisture can lead to structural damage, including wood rot wood and rusted metal, and is also an attractant for insects and wildlife. Mosquitoes, for instance, breed in standing water.

Prior to entering the crawl space, we donned our personal protective equipment. Mold is a bio-hazard in enclosed spaces and proper safety precautions must always be used. With gloves, masks, and goggles in place, we began a thorough inspection of the crawl space. There were multiple water puddles throughout the crawl space, so the area was ripe for mold growth. However, after inspecting every nook and cranny of the crawl space, we couldn’t find any mold growth that had yet taken hold. 

Continuing our inspection, we concluded that the moisture was coming up right through the dirt floor soil. Soil is a porous medium that acts like a sponge. About half its volume is air space and the other half is mineral and organic. It can soak up a large amount of water from above and below. Different soils have different water-holding capacities based on its porousness up to its point of saturation when all its pores are full. After rainfall, soil soaks up water, and once the soil is saturated, it will form surface puddles along with moisture and humidity. Although it was a good sign that there was not yet any mold growth in the crawl space, with this level of moisture build-up, it was only a matter of time before mold would form. This was a case where a homeowner had the foresight to realize there was a potential problem and contacted us early on. Usually, we are contacted after mold has already formed.

It was time for us to upgrade the crawl space. For this job, the homeowner requested that we install a vapor barrier. But not any vapor barrier. Many of the vapor barriers installed are no better than contractor bags. We use super-durable, 20-mil 7-ply plastic sheet material made up of high and low-density polyethylene with polyester-cord reinforcement. These barriers are as tough as nails and can be walked on without fear of tearing. We placed the vapor barrier on the dirt floor crawl space and anchored it directly into the wall. This barrier will deter moisture from entering the crawl space. A dry crawl space prevents mold growth and other water-related problems.

This job was a great example of a homeowner taking a proactive approach to prevent mold and mildew growth. Crawl spaces are notorious trouble spots for homeowners. It’s far better to identify and fix crawl space water and moisture problems before mold takes hold. 

Recently, we went on a service call for a homeowner in Point Pleasant Beach NJ, who was having an issue with birds getting into his home. As we inspected the exterior of the home to find the birds’ point of access, we came across a damaged plastic exhaust vent. As we took a closer look, a Starling peak his head out of the dryer vent and flew off!

Starlings are stocky black birds with short tails, triangular wings, and long, pointed bills. They nest in holes and cavities and often use holes in buildings — primarily dryer vents. Sterlings will exploit a vent opening to build a nest inside the home. Damaged exhaust vents not only allow birds and other critters to gain access to your home but also allow moisture to come in, which can lead to mold and mildew problems. 

First, we thoroughly inspected the entire interior and exterior of the home to find any other nesting areas, to which we didn’t find. Next, we spoke with the homeowner regarding the dryer vent and mentioned that it needs to be replaced. He agreed and immediately scheduled an appointment with a contractor. Then, we sanitized and deodorized the vent with a solution that targets bird mites. Bird mites are tiny, semi-transparent parasites that feed on the blood of birds. When birds leave their nests, the mites are left behind without a suitable host for their next blood meal. They will enter a home and feed on the blood of humans. Bird mites are the main reason why extreme care is needed when removing a nest. 

After removing all remnants of bird activity, as a temporary solution, we secured hardware cloth on the inside of the vent to prevent any more birds from attempting to access that area. Now the homeowner will no longer worry about annoying birds gaining access into his home.

After meeting with one of our sales inspectors, a new customer in Point Pleasant Beach, NJ wanted Cowleys to add some much needed insulation in his crawl space. When we arrived, we saw that the crawl space was full of debris and there was barely any insulation in the crawl space. Little to no insulation in a crawl space can make your floors feel cold, cause excessive moisture to build up, and lead to mold & rot issues.

First, we removed all the contaminated insulation & debris, discarded them properly, and cleaned up the joists. Once we finished, we installed new ComfortTherm® insulation throughout the entire crawl space. ComfortTherm® insulation improves energy efficient and provides excellent sound control. 

A homeowner in Seaside Park, NJ, contacted Cowleys after hearing strange “thumping and scratching” wildlife noises coming from the attic. Something was up there, but she wasn’t interested in investigating to find out what type of wildlife had taken up residence in her attic. Common “attic invaders” that we deal with are squirrels, raccoons, bats, and birds. Here, it turned out that the culprits infesting the attic were squirrels. 

Upon arrival, for the start of my inspection, I want to determine how the animals are gaining access into the attic in the first place. Unless it is a flying animal, the animal must first find a way to gain access to the roof (usually, it’s an overhanging tree branch or utility wires coming into the roofline area) and then, once on the roof, they look for some weakness in the roof structure to exploit. Often, with large wildlife, it’s not a mystery. There is an obvious entry hole in the roof or around the roofline. Here, however, at first glance, I did not see any visible damage indicating where the wildlife was finding its way inside. Upon closer inspection, I found the answer. All four of the plastic static roof vents had large holes chewed through them. Squirrels are in the rodent family and they have razor-sharp teeth that can eat through many types of building materials.

As you can see from the photo, the hole was underneath the plastic cap so it was not causing any water leakage. Nevertheless, the hole was more than enough for squirrels to gain easy access to this homeowner’s attic. Unfortunately, manufacturers do not usually design vents to be pest-proof. Contractors are looking to save money on their projects and price considerations affect the quality of “manufacturer’s standard” building materials. 

To resolve this problem, I covered three of the four roof vents with a tough galvanized steel mesh cover that fits over the entire vent. This cover is strong and durable enough to stop any wildlife from even thinking about using the vent to gain access to the attic. Why didn’t I cover all four vents? I wanted to allow any squirrels hiding in the attic a route to leave. With three of the four access points closed, the squirrels had no choice but to exit through the remaining opening. On this fourth vent, I installed a makeshift temporary cover attached to a one-way door. The door allows animals to leave, but it’s a one-way trip. They are unable to regain access into the attic. Once any animals are trapped and relocated and we are certain that there is no more wildlife activity inside the house, the fourth and final vent cover will be installed. And this wildlife job is complete — all wildlife is safely and humanely removed from the home and all entry points are sealed to prevent a re-infestation.

Recently Middletown Township, NJ homeowners contacted Cowleys after noticing some debris coming out from the drop ceiling in their finished basement. Upon arrival, I immediately went into the basement to inspect. I popped out the tile and immediately noticed that something had been chewing on the tile itself. I had a strong suspicion that this homeowner had a mouse infestation. After entering the home through gaps and cracks around the foundation, they will make their way through wall voids or travel on top of drop ceilings to forage for food and water. We see a substantial uptick of mouse infestations when temperatures drop and mice attempt to gain access inside our homes to overwinter to escape the harsh outdoor elements and forage for food and water. 

Mice, as all rodents, have incisor teeth that constantly grow. To keep them at a reasonable length, they will gnaw on almost anything they can get their teeth around as well as grind their teeth as a way of slowing their growth. While inspecting the sill plate, I found the tell-tale sign of mice — the rice-like droppings they leave behind.  Adjacent to this area, I noticed several wires going to the outside with a noticeable gap around them, allowing mice to enter. Gaps around pipes and wires entering the home are one of the more common entry points for rodents.  

I vacuumed up the toxic droppings and then placed a rodent bait station on the sill plate. Mice will follow the same trail, so placing bait stations in their pathway is highly effective to reduce their populations. I temporarily sealed the gap around the wires using chew-proof copper mesh. The homeowners informed me that they would have their contractor permanently seal the gap with stucco to prevent a re-infestation. With mouse infestations, to permanently resolve the issue and prevent re-infestations, it is essential to locate and seal all of the potential entry points around the home.
