Foundation VentGuard™ by HY-C - 10 Pack

I live on the East coast in a house with a 32 inch crawl space foundation. I noticed some rat droppings on my vapor barrier during the summer and discovered that some rats from a nearby barn were chewing through my crawl space foundation vents in order to gain access to the crawl space. Once inside, they would urinate and defecate everywhere, as well as make tunnels in the insulation and drag some of the insulation out of place due to their strength and large size. I went the quick and cheaper way of merely sealing up the compromised vents with some cheap covers from a hardware store. However, it is not good to do this with all of your foundation vents because your crawl spaced needs to be able to breathe and circulate air. So, the better solution is these foundation vent guards. I installed mine a little different by placing them on the inside of the crawl space instead of the outside. This way I have the double protection of house vents and the vent guards in keeping rodents out. Before I installed these, I had trapped and killed close to 30 full size rats and a handful of their litter. Now I don't have to worry about rats thanks to these vent guards. They are steel and too hard for rodents to chew through. They are also great looking too. I chose grey and they actually look like they came with the house when it was built. You will need mason Tap screws and an impact drill to install these. If you install them from the inside of your crawl space, you should not need to secure all 8 holes because no one will see them from the outside of the house anyway. Just a couple of screws placed on opposing sides will secure these enough to keep anything out. I used Alien tape to set each vent guard in place before drilling the screws. You could probably get away with just the Alien tape if you choose to do like I did by installing the vent guards from the inside of the house instead of on the exterior. Highly recommend this product as a lifetime solution for critter protection!

Just installed these for the first time. They look good and were easy to install. They were thin enough to slide under the vinyl siding that was partially covering the vent. Plan ahead and paint your screws ahead of time and then touch up if needed.

I had my first rental home with rats. The foundation is black painted brick so I ordered the black version of this product. It looks great and is super functional. I'll buy more for my other properties.

Fast service and good product. Sturdy and easy to install.

Very pleased with quality of product. They look great and seem to be keeping out unwanted critters!

Easy to install / Well made / Look Good / Rats don't stand a chance!

These are perfect to cover crawl space vents to keep pests out. Here in Florida small geckos can get through, so may want to put mesh screen on inside before attaching to keep them out. Very heavy duty and worth every penny.

These vent guards are really nice. I highly recommend them as they go over the existing exterior vents to keep all critters out from under the house. I feel safer now that these are installed.

These are great. Installed easily with construction adhesive and fit the vents perfectly. Looks are clean and subtle. Very happy with these. On the coastal range so we will see what the salt water mist and air does over time, but being stainless steel and painted, I have high hopes.

I finally got around to completely redoing my vented crawlspace which consisted of replacing all the insulation, vapor barrier and sealing any holes or gaps in the vents. I noticed a few had holes in the vent screens so was looking for a way to rejuvenate them and these ventguards are the perfect solution! Strong, easy to use over my existing vents and will provide years of great protection from critters trying to enter. Something most of use overlook and should pay attention to and gives the standard vents superpower!
