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.

The Cowleys nuisance wildlife crew was sent to this home in Atlantic Highlands, NJ to handle the exclusion work following a wildlife infestation in the attic. The wildlife access points were around the PVC roof vents caused by deterioration of the surrounding vent boots. We arrived to do the repair work to fix the problem.

Vent boots encase the PVC vent pipes that stick out of your roof. When doing repairs around vent pipe flashing after wildlife entry, homeowners sometimes ask us why their home even has these mysterious vent pipes since they seem like nothing but trouble.

These pipes are part of your plumbing system, or what plumbers call you drain-waste-vent (DWV) system, At the risk of oversimplification, this system has three major parts. The “D” stands for drainpipes, the pipes that collect water from sinks, showers, tubs, and your appliances like your dishwasher and washing machine. The “W” stands for waste pipes, the pipes that remove water and waste from your toilets. All of these pipes connect to the municipality’s sewer line or your septic system. The “V” stands for the vent pipes that stick out of your roof. Building codes require at least one of them.

Vent pipes have two important functions for your plumbing system. First, they equalize pressure in the pipes by allowing air to enter so that the liquid flows freely. (Just think what happens if you put your thumb over a straw immediately after you suck in liquid or if you try to pour liquid out of a can without a second air hole. Without air in the system, water doesn’t flow well.) Second, these vent pipes remove or exhaust sewer gases that are produced and collected from the decomposition of wastes in the sewage system. Sewer gas contains a number of nasty gases including hydrogen sulfide and ammonia that are flammable, poisonous, and just plain stink. These vents are put high up on your roof so that the sewer gas is not pulled back into the home through the windows or attic. 

So, if all that’s too much information, the short answer is that you need those vent pipes sticking out of your roof for your plumbing system to work. Unfortunately, even though these vent pipes are essential, they are also rank up there as one of the most common causes of roof leaks. In addition, the PVC vent areas are vulnerable to wildlife like raccoons that can tear through the vent flashing to gain access to the attic. 

To help prevent leaks and give some added protection against wildlife entry, vent boots seal the area where the pipes come out. Unfortunately, vent boots often don’t last the life of the roof. Because they’re usually made out of rubber, over time, the sun and the outdoor elements will cause them to rot. With this home, the vent boots had deteriorated to the point where they were gone completely, leaving entry points for water intrusions and for pests and wildlife to gain access inside the home.

These homeowners in Atlantic Highlands, NJ, were having problems with squirrels “squirreling” their way into their attic. They were tired of dealing with these periodic squirrel infestations into their home, and contacted Cowleys in the hopes of finding a long-term solution. We had the perfect answer for them! 

Our contractor division installed CritterProof, a critter protection product manufactured by Leaf Supreme, a leading designer of gutter protection systems. CritterProof is specifically designed to cover the fascia gap and exclude various wildlife that often makes their way onto the roof and into the attic. The most common “attic invaders” that we see time and time again here in New Jersey are squirrels, raccoons, and bats. Mice also find their way into the attic, but usually they first enter the home through the basement or crawl space. 

CritterProof is a protective system that stops wildlife from chewing and clawing their way through the delicate fascia boards to gain access to the soffit area and, ultimately, where the attic. For wildlife, attics are the perfect refuge to escape the harsh outdoor elements and they make for a wonderful nesting area to care for their young. After all, attics are warm, quiet, private, and free from the preying eyes of predators.  

A home’s soffit/fascia area is one of the more common routes we see for wildlife to gain entry. CritterProof’s unique adjustable design provides custom coverage of the fascia gap while still maintaining critical attic ventilation. CritterProof is available in black, white, and other colors by special order.
