Why Use Crawl Space Vent Covers?

Crawl space vent covers allow for more cost-efficient temperature control in your home. Vent covers act as an extra layer of insulation, preventing air from escaping and entering the crawl space network. Maintaining a comfortable ambient temperature in humid summers or crisp winters can be expensive in improperly insulated homes.

Vent covers keep that humid, summer air out of your crawl space, and stop the heat from escaping during colder weather. This keeps energy costs down and prevents condensation from forming due to the conflicting air temperatures. Controlling humidity and moisture also prevents any wood rot and mold-related problems from forming. Further, vent covers stop pests and vermin from being able to enter your crawl space.

Vent covers are one of the best ways to fortify your crawl space against myriad crawl space problems involving moisture, temperature control, and pests. In preventing these from happening, you are securing the health and value of your home and protecting your family from mold and pest infestations.

Signs Your Crawl Space Needs Vent Covers

A lack of vent covers, or non-airtight variants, can allow a number of problems to develop in your crawl space. These problems can spiral out of control if left unattended, leading to property damage and hampered air quality. Thankfully, there are signs of moisture in your crawl space that arise before the damage grows beyond repair.

Carefully inspect your home and crawl space for any of the below symptoms, or consult with a moisture control expert at Groundworks for symptoms specific to your location.

  • Mold and Mildew

Not sealing crawl space vents from the elements allows damp air inside and effectively traps it beneath the home. Not only does this create a damp environment, but it also fosters the growth of fungus. Mold and mildew, types of fungus, thrive in moisture-rich spaces like waterlogged crawl spaces.

The presence of these organisms reduces indoor air quality as they release spores. These spores can impact your family’s health. Namely, they can cause respiratory issues, like difficulties breathing and irritation of the mouth, eyes, nose, and throat. People with asthma or allergies will feel these symptoms to a greater degree than others—to the point where they may be unable to live comfortably in the home.

Left untreated, mold growth will progress until they move up from the crawl space and into the home. Color varies across mold species, although most will appear as dark specks on walls, floors, and objects. Clusters of mold growth can often be spotted in corners and along the wall-floor joint in rooms.

  • Unpleasant Smells

Trapped moisture creates a damp smell. Alone, this may not seem troublesome, which is why some might ignore the warning signs such smells present. The longer this moisture is allowed to gather and stagnate, the stronger and more pungent this smell will become. Once mold and mildew begin to feed on this trapped water, a new layer of scents will be released. These organisms generate a musty, unpleasant smell that grows in conjunction with the size of the mold colony.

Mold and mildew odors linger in fabrics, wallpaper, and furniture. Mold smells are also known to attract pests, which will add yet another slew of unpleasant smells. Once these pests have settled into crawl spaces and unsealed vents, they too will create a noticeable odor of mustiness and urine.

These scents will be more concentrated where the pest colonies are nesting. Depending on the scale of the infestation, the pungent odors may permeate the entire home or be confined to specific rooms.

  • High-Energy Usage

An unusually high energy bill during summer and winter peaks is an indicator that you are spending more energy regulating the home’s temperature. In summer, open crawl space vents allow warm air to seep in under your home. As this warm air rises, it creates a dense cloud of humidity in your living space. Often, this applies more pressure on interior cooling systems as you attempt to combat the heat by leaving the devices to run longer. The same can be seen in colder weather as the chilly air inside the crawl space vents saps the warmth from the heated interior. This amounts to an expensive energy bill at the end of every month. Vent covers do a great deal for creating a more energy-efficient home.

  • Pest Sightings

Discovering evidence of pests in your home is unsettling and a sign that your vents are not only attracting pests but housing them. Finding droppings, signs of tunneling or nests, dead cockroaches and molted skins, and holes gnawed in walls or furniture are indicators that pests are nearby.

Aside from confirmed sightings of rodents, you may also hear them scurrying through the vent spaces at night. Vent covers are great tools for deterring pests as they lock them out of the vents entirely.

  • Peeling Wallpaper Or Paint Bubbles

Moisture trapped in crawl spaces and vents will eventually cause wallpaper to peel or paint to begin bubbling. Damage of this kind often means the damp has seeped into the drywall or baseboards. In fact, dehumidifiers may be required to prevent further damage, and walls will need to be repapered or repainted. Add it all up, and this can be quite costly. A prime solution to prevent this situation from happening again, or at all, is to invest in quality vent covers.

FAQs About Vent Covers

Maintaining your crawl space vent covers is one thing you might worry about. If you add a crawl space vent cover, do you have to continue putting money, time, and energy into it? Here’s what you should know about crawl space vent cover maintenance.

  • Possibility for Issues

If you have crawl space vent covers that don’t utilize high-quality materials, it’s true that you might have issues with airflow and water entry. Crawl space vent covers need to be as high quality as possible.

If your existing vent covers are made from a different material, they may need to be upgraded. A Groundworks expert can recommend the ideal solution for your home if you are concerned that your vent covers aren’t doing the job.

  • High-Quality Materials

There are many reasons to get a crawl space vent cover for your crawl space vents. If you regularly have flooding issues around your home, you might be looking for a crawl space vent cover that can help you avoid water in the crawl space. This can be a very useful element of a crawl space vent cover if you know how to do it.

  •  An Airtight Seal

The most important thing to keep in mind is that crawl space vent covers need an airtight seal to keep water out. Groundworks’ chosen vent covers, CrawlSeal Vent Covers, provide a complete solution from start to finish.

Airtight seals keep the dry air inside and humid, moisture-laden air out. These seals also keep vents free from water during rain and minor flooding events.

  • Maintain Your Crawl Space Vent Cover Quality

Remember, when you ensure that you only have high-quality crawl space vent covers, you’re much more likely to avoid issues with those same vent covers. The best way to avoid necessary replacements is to start out with something high quality.

The highest-quality crawl space vent covers will always be better. Maintain your home’s health and well-being. Refuse to settle for anything other than high-quality crawl space vent covers like CrawlSeal.

When you have open crawl space vents, you’re also typically going to have lower-quality air in your home as a whole and in your crawl space specifically. It’s one of the first things you’ll fix as part of a crawl space encapsulation strategy. Here’s how open crawl space vents can be unhealthy for your home.

  • Humidity Issues

Open crawl space vents can be especially unhealthy in humid climates. Moisture in your home’s vent network can cause property damage, attract pests, and spark health problems.

None of these outcomes are ideal and can be costly to resolve, even before they grow out of control. Plus, because crawl space vent covers allow different temperatures of air to come into the crawl space, it can create humidity where there previously wasn’t any.

  • Infestations

An open crawl space vent is one of the biggest reasons that you might end up with infestations. Mold and pest infestations in particular are known for impacting the health and well-being of residents.

Pests are carriers of disease, allergens, and bacteria, and mold can also increase your risk of allergies and asthma. Cutting off one of the main methods of entry, the crawl space vents, is a crucial element of avoiding these infestations.

Some people might wonder why they can’t just utilize crawl space vents that close. While most vents do have shutters or rudimentary covers that can be closed at will, these definitely aren’t the best solutions. Closing the crawl space vent shouldn’t be your first choice; installing a crawl space vent cover is a much better option.

  •  Not Airtight

One of the biggest problems with just closing a crawl space vent is the fact that it’s not going to be airtight. That essentially removes the reasons for closing the vent in the first place; air and water can both leak through a vent cover that’s not airtight.

An airtight vent cover will help you fix your crawl space. CrawlSeal vent covers are airtight and made from a durable plastic material that circumvents any future issues with rust or exposure damage.

  •  Long-Term Protection

It’s important that you don’t just think about the short term when it comes to your crawl space needs. Long-term protection should be one of the most important things that you consider; it’s less expensive and less time-consuming, especially in the long term.

When you talk to a Groundworks expert about your crawl space needs, they’ll help set you up with crawl space vent covers that will work for good.
