General FAQ – Foundation Vents – Garage Vents
Can EZRvents Be Painted?
Yes, all of our EZRvents can be painted with newer paints that have been formulated for plastics (Polypropylene). EZRvent frames can also be painted with a good quality house paint if properly prepared.
We have tested and found best results with Krylon Fusion, Rust-Oleum Specialty Paint For Plastic, or Valspar Plastic and using a 1st coat of Fusion Primer for plastic, Rust-Oleum Specialty Plastic Primer, or Valspar Primer for Plastic. Many of our installers do this with great long lasting results.
We also have also have good results painting EZRvents with good quality exterior house paint if properly prepared with Flame Treatment or other prep as outlined in our Polypropylene Frame Painting Instructions. Then Followed with 2 coats of Valspar "Primer for Plastic", Krylon Fusion Primer, or Rust-Oleum Specialty Plastic Primer. Both the Preparation and Primer for Plastic step is important for proper adhesion.
We should emphasize that it is Equally and most important Prior to priming, is to clean and prepare your vents for painting by Flame Treating and wiping with alcohol; -or - lightly sanding the surfaces with sand paper and wiping with alcohol. Surface tension and residual mold release may otherwise affect your results even if the paint manufacturer does not specify this.
For detailed painting instructions, See: How to Paint Polypropylene Frames
Another option is to have us custom color match your vents. See: http://www.ezrvent.com/faq-service/order-policies/#-Custom-Color-Orders-Painted-
What type of Plastic are EZRvent Frames?
EZRvent Frame UV / Sun Protection & Life?
Our FV100 is made of a durable UV protected Polypropylene plastic and heavy gauge 1/8" mesh metal screen that will last for years. Our Polypropylene Frame Material is similar to what is used in Auto Body Bumpers, with glass fibers for added structure. We also use the maximum UV protection available in our formulation. The Auto industries use this type of material in painted and unpainted applications.
We have done extensive accelerated life testing in salt spray and UV environments and used competitor products as a baseline. In all cases, our EZRvent lasted 4 times longer than the Big Box products for salt spray. For UV Testing, with a 10 year simulated direct exposure aging, we did not see a degradation of our material properties other than the surface oxidation (becoming dry looking, slightly yellowing and slightly exposing the Glass fibers). Competitor vents made of other plastic materials did not retain strength and greatly yellowed to a light brown or lost 80% of color.
Our real life testing in a Sothern California coastal location in fog belt and salt spray zone has been ongoing and is in its 7th year now. All EZRvent Heavy Models in testing have not started to rust and the frames have remained the original slightly flexible state. Our light Economy mesh (discontinued) has just started to show a tinge of rust. Competitor and big box products are all showing signs of rusting. For added life on the plastic frame, one can paint the frames to avoid plastic oxidation. When painting, you should expect typical paint life and would require re-painting as you would your house.
Do I Need Stainless Steel Vents?
If you live on or near the coast, it is a good idea for great looking and long lasting
Will Stainless Steel Rust?
Stainless Steel can rust depending on grade and if surface contamination from tooling is left on the surface. Iron rich soil or other dust can also contaminate the surface and give a rusting appearance and or seed rusting.
Our EZRvent 316 Marine Grade Stainless Steel is highly resistant to rusting due to its grade and our processing. All of our 316 Marine Grade Stainless Steel is passivated / chemical etched using "green friendly" but strong citric based acids to remove surface free iron and contamination from the screen forming and cutting operation tooling. This makes for a highly rust resistant product.
If a shiny rust free appearance is desired, periodic maintenance may be required depending on your location/environment. We recommend fast and easy CitriSurf Stainless Steel cleaners to return your Stainless Steel vents back to a like new condition.
Do I Need Copper Vents?
Copper Mesh is Best Option for Coastal Installations.
If you live on or near the coast, this is the best solution in the salt spray or mist zone for great looking maintenance free and long lasting
Why Install EZRvents For Pest Control Exclusion?
Installing EZRvents is an easy way to replace and upgrade rusted out foundation vents, garage vents, and attic eave vents that are in need of replacement for active or preventative pest exclusion with the added benefit of adding an upgraded finished look to your job.
Installing EZRvents is a significant net savings cost advantage per job even when compared to installing bare mesh.
For this reason, we recommend installers charge per job and not per hour rates.
Many Pest Control Contractors are finding our Replacement Vent Products an easy way to add another revenue stream to their business. Pest Control Installers are making $200-$300+ for an hour or two easy installation time on typical homes. Simply keep an eye out for rusted out or damaged vents while on your normal rounds.
Typical complete EZRvent retrofit installation takes a little over one minute per vent with no stucco or siding work required.
As seen in our video (http://www.youtube.com/user/EZRvent ) installation is quick and easy; requiring low effort, standard tools, and low skilled labor to produce a high value finished solution.

Are EZRvent FV100 vents strong enough to block out Raccoons, Skunks, and Opossum?
Yes, our EZRvent FV100 vents are strong with a continuous heat stake around the perimeter of the vent vs just being spot welded. Our Heavy Stainless option is the strongest option. However, if your raccoons, skunks or opossums are trapped in or young were trapped inside; there will not be much that they will not rip trough; even solid plywood.
How to get rid of raccoons, skunks, opossums or other critters from under your house?
If you have raccoons, skunks, opossums or other critters under your house, you will need to make sure that they have moved on before sealing up all your vents completely. You will also need to retrain them that your house is not a great place to call home within their territory. Until you are able to change this behavior, they will tear through any vent on the market including solid plywood to get back into what they have set-up to be the best house in the neighborhood. You will also need to keep in mind that raccoons, skunks, and opossums are nocturnal and if you seal up your vents during the day, you could be trapping them in. They will also tear through just about anything to get out if trapped in or back in if their young remain inside. Also, if they have young that are too young to move, it will be even more difficult to encourage them to relocate until they are old enough to be moved.
So how do you change their learned behavior and get them to move on and call home someplace else?
The Humane Society is a good source of information for how to encourage raccoons, skunks, opossums and other critters to relocate and discourage them from wanting to return in the future. The Humane Society discourages the use of traps for catch & release after relocating. This places the critters into unfamiliar territory and separates the family unit, both being detrimental to their survival.
Humane alternatives are to simply make the area an undesirable location for the raccoons, skunks, or opossums
EZRvent Installers and DIY customers have reported having good luck by simply lighting up the spaces with bright work lights. If that is not effective, following the methods prescribed by the Humane Society usually does the trick: “If you can’t wait for the animals to leave on their own, the next best strategy is humane eviction— gently harassing the animals so they’ll move to an alternative location. Wild animals have a sophisticated knowledge of their home ranges—the area in which they spend almost their entire life.” “Litters can, and will, be moved if disturbed” to a more hospitable location. “Try using a combination of unpleasant smells and sounds. The size of the
If the animals are not causing damage or harm, you can be assured that once the young are big enough to be out and about, the birth den will have served its purpose. The denning and nesting season is short. Be tolerant and wait a few weeks until the family has vacated the premises and you’ll prevent orphaning of the young altogether. Then, you can make repairs to prevent animals from moving in again.
If the critters are doing active damage, more aggressive methods that include pepper sprays such as Critter Ridder and or other repellants could be also used.
Before completely sealing up their access points you will want to make sure they have moved on. Otherwise, they will tear through just about anything to get back their young and or out if trapped in. Most sources recommend temporarily closing up openings by stuffing the openings that they were using with newspaper. This will tell you is they are still using that opening if the paper blockage is disturbed. Or, our preferred method is to just place or wedge your EZRvents into place temporarily with shims (without screwing them in) for the first several weeks. That way they could be pushed out if you have trapped a skunk or raccoon inside.

Why Painters and Window Installers are Installing EZRvents?
Painting and Home Improvement Contractors are finding Replacement Vent Products are an easy way to add another revenue stream to their business. Installing EZRvents is an easy way to replace and upgrade rusted out foundation vents, garage vents, and attic eave vents that are in need of replacement on older homes or to add a finished look to your job on newer homes as an upgrade. EZRvents also perfectly complement vinyl windows and doors. Installing EZRvents is a significant net savings cost advantage per job even when compared to installing bare mesh. For this reason, we recommend installers charge per job and not per hour rates. Typical complete EZRvent retrofit installation takes a little over one minute with no stucco or siding work required. As seen in our video ( http://www.youtube.com/user/EZRvent ) installation is quick and easy; requiring low effort, standard tools, and low skilled labor to produce a high value finished solution.
Do EZRvent Close? or Have Covers for Winter?
EZRvent vents do not close or have covers for winter. EZRvent vents were designed for good looks, ease of installation, to block out all the critters, and maintaining maximum air flow year round for the non snow/ freeze zones were shuttered or closable vents can actually do more harm than good. Even in the snow/ freezing zones, most building codes specify non closable vents due to local conditions (i.e. potential of radon, freeze thaw, or other conditions) were ventilation is preferred to minimizing heat loss by these means.
Most building codes require open ventilation and recommend insulating the underside of floors for energy efficiency and isolation from the coldness. Other typical options per codes is to have an air exchanged or an actively conditioned air space if closed.
FEMA codes also require open ventilation / non-closing vents that remain open 100% of the time. "Must not block or impede the automatic flow of floodwaters into and out of the enclosed area." "Manual or automatic open and close based on temperature are unacceptable unless permanently disabled in the open position."
Even if we had them, we would not recommend vent blockers for almost all areas. We suggest consulting your local building codes and reading our Open vs Closed Foundation Vents FAQ.

Blocking of vents
Even if we had them, we would not recommend vent blockers for almost all areas.
Typical Building codes and energy efficiency guidelines:
A good quote from City Inspector Larry Caldwell on the topic:
“People who block up their foundation vents in the winter cause a lot of dry rot and termite problems by trapping moisture under the house. Most houses nowadays have adequate foundation vents. Oregon has had a building code since 1973, and houses built before then have either been repaired or rotted into a pile of rubble.”
Do EZRvent products meet Local State & FEMA building codes?
Yes, all of our EZRvent products have been designed to meet or exceed most state & international building codes along with FEMA requirements.
EZRvent can be used to meet FEMA Openings in Foundation Walls and Walls of Enclosures - Non-Engineered Openings requirements without modification.
The only exception is Wildland-Urban Interface Code (Chapter 7A) for New construction in "Very High" wildfire interface risk zones where more expensive fire/ flame blocking vents would be required. Note: Chapter 7A requirements are only required in "Very High" Fire Hazard Safety Zones (FHSZ) and for New construction after 2008 in those zones. High and Moderate FHSZ areas do not require Chapter 7A materials. Our Mesh materials comply with 7A, but our weather and
We suggest consulting your local and regional building codes.
Many building code regions are also now also specifying 1/8 inch mesh opening to block out Africanized bees. If that is your case, look closely at the vents you are considering. Many vents on the market today do not meet this code change or do not even block out larger critters. All EZRvent products use 1/8 inch mesh as standard.
How Many Foundation Vents Should My Home have?
Most building codes require 1 square foot of open ventilation area for every 150 square feet of crawl space. EZRvent FV100 Foundation Vents have ~29 inches of net free ventilation area per vent (dependent on mesh type). Therefore, you should install approximately one EZRvent for every 30 square feet of crawl space. Note that levered vents drastically reduce the amount of open free ventilation area and increases the number of vents that would be required to maintain adequate ventilation.
Whenever possible, vents should be placed on all sides of Home Foundations. This provides steady cross flow ventilation for any air flow direction.
For crawl spaces with plastic or other moisture barrier sheet installed, on 80-90% of the ground, most ventilation requirements changes to 1 square foot of ventilation for every 500 square feet of crawl space with a minimum of 4 vents installed to provide cross ventilation. For crawl spaces with barrier laid down, at least one vent for every 123 square feet of crawl space should be installed. Note that some moisture barrier sheets will age and degrade or get damaged from workmen access and should be inspected. If not properly installed or maintained, moisture barriers can trap moisture and or let moisture pass through leading to problems.
EZRvent FV100 open ventilation area:
Net Free Ventilation (NFV)
35.5 sq in (* Discontinued - Thinner Economy mesh no longer meets code in many areas)
31.6 sq in
28.8 sq in
28.8 sq in
35.0 sq in (**1/4" mesh no longer meets code in many areas)
Custom Sizes and Custom Size Orders
Our FV100 vents can actually be modified to fit down to a 4.5" x 12.8" rough opening, or other combinations of .25" reductions per side from 5 x 14 ( i.e. 5" x 13", 4.5" x 13", 4.5" x 14" or . . .) by trimming some spacing shims that are on the back side. This is an easy modification to do with a Multi Tool, Dremel Tool, or Router.
