Before & After Photos

We recently replaced five foundation vents with Smart Vents for a homeowner in Manasquan, NJ. The old vents would not adequately protect the home from damage in the event of floodwaters from a severe weather events such as a hurricane, tropical storm, or nor’easter, which unfortunately seem to be occurring more frequently and with greater severity. Often, we can simply remove the existing vents and replace them with Smart Vents. However, sometimes, as we did here, we must cut into the foundation to properly fit the improved vents. Either way, the transition from traditional vents to Smart Vents is easy and seamless, and at the end of the day, the homeowner is left with considerable protection of their home foundation against damaging floodwaters. 

Smart Vents prevent severe foundation damage by equalizing hydrostatic pressure. Hydrostatic water pressure can reach tens of thousands of pounds. It’s enough pressure to collapse large dams and retaining walls let alone home foundations. They work by allowing floodwaters to freely enter and exit the basement or crawl space. And how they so it is deceptively easy. Unlike traditional air vents, these vents open automatically and passively on their own once floodwaters reach a certain level. They do not require human intervention and no electricity is needed. The vents provide a 3-inch clearance for small debris and trash to easily pass when the vent door is opened by patented internal activation floats. For vented crawl spaces, there are Smart Vent models with a metal coil sensitive to temperature changes that opens and closes the vent louvers, and, just like the Smart Vent models that respond to water levels, these vents open and close automatically and do not require manual intervention.

Perhaps most important, these vents are FEMA and NFIP (National Flood Insurance Program) compliant. They are deemed so effective by these agencies that the installation of these foundation flood vents can save homeowners, on average, 80% of their NFIP premiums. Any Jersey Shore homeowner with a crawl space or basement in a flood hazard area, especially NFIP-designated V Zones and A Zones, should strongly consider installation of Smart Vents. Smart Vent has its own Flood Risk Evaluator division to ensure that Smart Vent purchasers receive the proper flood insurance rating. They can provide homeowners with an estimate of their new lower flood insurance premium at www.yourfloodrisk.com.

As we get into the winter season and temperatures start dropping, mice become more of a nuisance for homeowners. For survival, these overwintering pests look for warm, dry places to escape the harsh outdoor elements — and our homes are often their targets. Unlike larger wildlife, mice can find the smallest entry points around a home’s foundation to gain entry. They can gain entry through an opening as small as the size of a dime. If they can poke their letting snout into an opening, the rest of the body will follow. Common mouse entry points are garages and crawl spaces. Once inside, mice will travel through wall voids to stay out of sight as they forage for food.  

I was sent to a home in Manasquan, NJ to deal with a mouse problem that was frustrating this homeowner. For mouse infestations, it is critical to perform a thorough inspection of the interior and exterior home perimeter in order to find and seal all of the potential rodent access points. Often, there are droppings and other signs of mouse activity around the openings. Once we find any openings, we assess the problem and seal the gap using a variety of different methods. Because rodents have powerful incisors and an amazing capability to chew through many building materials, we will use chew-proof mesh to ensure that the opening is permanently blocked. With access points blocked and bait traps set, it does not take long for any mouse infestation to be quickly dealt with.

Recently, Cowleys installed two commercial-grade whole-house dehumidifiers in homes in Manasquan, NJ to deal with chronic high indoor relative humidity levels. High humidity can trigger dangerous mold growth and generic dehumidifiers are not built to work in the challenging environment of crawl spaces and basements. The SaniDry dehumidifiers we install and service are powerful machines that automatically empty, usually into sump pumps, so there is no water pan to empty or overflow. They turn on and off automatically with a built-in hydrometer. 

As many of us remember from Superstorm Sandy in 2012 or the many Nor’easters to hit the Atlantic coast, heavy rain can cause serious flooding in basements and crawl spaces, especially in our hard-hit coastal communities. Because of the high water table and potential for flooding in Manasquan, we wanted to install them in a way that would decrease the risk that they would be submerged should water flood the basement or crawl space and allow them to continue working. We framed boxes high above ground level to place the machines to keep them safe and operational should the home suffer from a major water intrusion event. We may not be able to prevent flooding, but there are preventative steps we can take to minimize flooding damage.

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.

This Brielle, NJ homeowner had a raccoon enter the attic through the soffit. The soffit is the underside of the roof overhang. It is commonly made out of aluminum or vinyl and has passive vents providing much-needed ventilation and air circulation to the attic and expelling the rising heat, which causes all sorts of problems both during the summer and the winter. Unfortunately, soffits, especially if they are damaged, are a favorite access point for wildlife to enter your attic. Raccoons and squirrels are innately able to find and exploit the weak points into a home, and soffits are at the top of the list of favorite entry points. 

Cowleys wildlife technicians had already come in to trap the raccoon, and immediately afterwards installed a temporary patch to seal the area. However, the homeowner wanted a more aesthetically pleasing repair. Cowleys has a home improvement division that, among other things, has an experienced crew that repairs damages caused by wildlife, termites, and other insects. The homeowner was quite pleased with our repair of his home, and so were we!
