3 Reasons to Protect Your Crawl Space

2026-08-29T00:00:00.05Z

Vented crawl spaces with dirt floors seem to be the standard across America. We highly recommend encapsulating your crawl space to better protect it.

Here are three reasons to protect your crawl space with an encapsulation.

1. MOLD

A crawl space with a dirt floor and vents allow for a lot of moisture to get in. When moisture is left to sit in the crawl space it usually leads to mold. Mold is very damaging to your home and your health. If their is mold in the crawl space it leads to mold spores and a musty smell being very prevalent in your home.

2. Structural Damage

An unprotected crawl space is much more prone to structural damage. Water can cause rot to settle in. Rotting beams and floor joists negatively affect the floors in your home and the structural integrity of your home as whole.

3. High Energy Bills

When outside air is getting into your crawl space your energy bills go up. If your crawl space is vented, the weather outside becomes the weather inside your crawl space. This causes the air to kick on much more often, and it has to work much harder to keep your home cool in the summer and warm in the winter.

If you are looking to prevent these problems from occurring in your home. Its time to reach out to the professionals about a crawl space encapsulation!

Egress Windows

2026-06-26T00:00:00.05Z

Does your basement have a safe exit option? An Egress Window System can provide this and more!

What is an Egress Window?

An egress window is an operable window that is large enough to be used as an escape in the event of a fire, disaster, or other emergency. Basements typically have windows that are too small to be used as a safe exit, but an egress window changes that.

Benefits

The biggest benefit of an egress window is undoubtably the safety and peace of mind it provides to homeowners. However, it also lets in a lot more natural light. This allows for basements to feel much more homey and comfortable.

System

The egress window system includes a large window well outside of the window. This window well has ladder rungs to make climbing out easy. A drainage system can also be installed in the window well to collect any pooling water and directs it right to the basement sump pump. This step will prevent flooding through the basement window. A window well cover can also be added for extra safety measures.

If you are interested in adding an egress window system to your basement, be sure to reach out to Chicago Basement Systems! We would love to help make your basement safer and brighter!

Say Goodbye to Humidity with a SaniDry Sedona

2026-04-03T00:00:00.05Z

Humidity in the basement or crawl space is not beneficial to the health of your home. Humidity leads to mildew, mold, and other problems. If you are experiencing high humidity in your home, you may need a SaniDry Sedona.

What is a SaniDry Sedona?

Put simply, the SaniDry Sedona is a dehumidifier. But it is not just any dehumidifier. This tiny but mighty powerhouse can remove up to 100 pints of water from the air each day.

Signs Your Home Needs a Dehumidifier

If you are having humidity problems in your basement or crawl space, the signs will make themselves known. Condensation buildup on HVAC systems, drooping insulation, mold or mildew forming on the structure of the home--these are all signs that humidity is way too high below your home.

What goes on beneath your home will soon make its way into your home. Musty odors and muggy air will begin to seep in to your daily life if the humidity levels in your basement or crawl space are not taken care of.

What Sets the SaniDry Sedona Apart

You may be wondering why we recommend the SaniDry Sedona over other dehumidifiers on the market. There are many benefits to the SaniDry Sedona:

Prevents mold and mildew
Reduces allergens
Removes asthma inducing particles
MERV 8 Filter
Stops musty odors
Self-Draining
Energy Efficient

These are just some of the many reasons that set the SaniDry Sedona apart from every other dehumidifier out there.

Spring Is Coming. Is Your Home Prepared?

2026-03-05T00:00:00.05Z

Spring is coming to Chicago! Well, eventually. With temperatures starting to get a bit warmer over the next two months, snow will be melting and rain will be coming. This means a lot of water will suddenly be sitting all around your home. No one wants the headache of a flooded basement just because our area is finally getting up above freezing on a good day.

The good news is the spring thaw and April showers don't have to mean flooding in your home. Get ahead of spring flooding with these easy steps.

Optimize Water Drainage

Gutters, downspouts, and proper grading are all important factors for water drainage. Proper water drainage works to keep water away from your home's foundation. Ideally water is expelled several feet away from your home as opposed to right next to it. Here are a few tips to remember:

Clean gutters work much better than clogged ones
Extended downspouts carry water further away from your home
Proper grading allows all the moisture to drain naturally away from your home

Making sure the drainage systems outside your home are just as important as the ones inside.

Waterproof Your Basement

If you have a basement that tends to flood, there are measures you can put in place to help this. Sump pumps help to keep water out of your basement. There are different strengths of sump pumps that can be chosen from depending on the level of water intrusion you experience. Subfloor waterproofing systems capture the water before you even see it. Trench drains and window wells help to keep water from seeping in through basement doors and windows. Waterproofing your basement helps to keep it protected from any level of water intrusion, and is a great way to get ahead of the wet spring season.

Waterproof Your Crawl Space

Did you know you can waterproof your crawl space, too? A lot of people don't really think about the crawl space because it's usually dark, dirty, and nasty; but protecting your crawl space from water is really important too. A crawl space encapsulation is the process of sealing your crawl space from the earth and protecting it from water, pests, and outside air. Your crawl space is a part of your home, too, and shouldn't be neglected. A wet crawl space is the perfect environment for mold and rot. While a dark crawl space may be easy to ignore, mold and rot will make themselves known very quickly.

Servicing Equipment

Maybe you have already taken the steps listed above. If that is the case, maintaining these systems is very important to their longevity. Sump pumps need to be cleaned and tested, dehumidifiers need to have their filters changed, and waterproofing systems should be examined to ensure they are in good working order!

How can we help?

Chicago Basement Systems has the knowledgeable experts and the warrantied, patented products o ensure your home is protected this spring! Are you ready to make sure your home stays dry, not only this spring but year round? Reach out today to schedule your FREE, no obligation estimate.

Crawl Space Encapsulation: Why Its Important

2026-02-13T00:00:00.05Z

Dirt crawl spaces may be common, but they are a design flaw that can be detrimental to the health of your home. Vents were once thought to allow the crawl space to breathe, but now we know they are just an easy way for water, outside air, and pests to slide right in to your crawl space. This is not good news! But what can we do about it?

Enter a crawl space encapsulation.

A crawl space encapsulation is the process of sealing the area beneath your home with a thick vapor barrier, in order to turn a wet, nasty space in to a dry, healthy, and usable space. A full encapsulation usually also includes insulation, a sump pump, and a dehumidifier. All of these products work in harmony to keep the crawl space in tip top shape.

A crawl space isn't just a way to make your crawl space look better, there are many lasting benefits to having this done.

Control Moisture

An encapsulation helps to get out any moisture that may seep in and hang out in the crawl space, but its also to protect from future water intrusion. One heavy rain or winter snow melt could be detrimental to the health of your crawl space. Being prepared ahead of time is much easier than dealing with the headache of a flooded crawl space.

Prevent Mold

A damp crawl space creates the perfect environment for mold to thrive. By keeping moisture out and the humidity low, dust mites and mold spores no longer set up house. This is very important because mold in the crawl space can cause serious problems. For one, mold leads to rot. Rot causes structural problems, and structural problems almost always come with a hefty price tag. Additionally, mold spores in the air won't stay in the crawl space. They will travel up into your home, into the very air you breathe every day. Yikes! A healthy home definitely starts in your crawl space.

Energy Efficient

A crawl space encapsulation can make a big difference on your energy bill, as much as 15-20% less! That's huge! This is because an encapsulation isolates the dirt crawl space from the earth, creating a thermal break. The added insulation on the walls and having the vents sealed help prevent outside air from impacting your home. No more cold floors in the winter or hot humid air making its way through the crawl space in the summer.

Keep Pests OUT

When a dirt crawl space is encapsulated it prevents pests like rats, snakes, and other nasty critters from making your crawl space into their home. You will no longer have to live in fear of coming face to face with creepy crawlies every time you need to crawl under your home.

These are just a few of the many benefits that come with encapsulating your crawl space. If you are in need of a crawl space encapsulation, give Chicago Basement Systems a call! Not only are we your local Chicago and NWI experts, but we also provide a free inspection and estimate!

5 Reasons to Waterproof Your Basement

2026-01-23T00:00:00.05Z

Does your basement start to leak every time it rains? Or maybe it's got that good old musty basement smell? It can be tempting to shut the basement door and forget about it; out of sight, out of mind, right? The problem with ignoring your wet basement is that it can lead to BIG problems down the road. Here are 5 reasons you should consider waterproofing your basement.

Protect Your Investment

Your home is arguably the biggest investment you will ever make in your life. It is important to take care of it. While its beneath your home and may be dark and smelly, that basement is still a part of your home. A wet basement can significantly impact the health of your home as a whole. Wet basements are a problem that only create bigger problems when ignores.

Prevent Mold and Mildew

You know that musty odor that is commonly referred to when speaking about how a basement smells? Its not really how your basement is supposed to smell. That musty smell is actually a sign of mold and mildew growing in your basement. Gross. Damp basements create the perfect environment for mold and mildew spores to flourish. These spores then get into the air and spread throughout your home, wracking havoc on allergies, asthma, and the household's overall health.

Safeguard Your Belongings

Most of us use our basements for storage. Boxes of memories, holiday decorations, and other treasures are often stacked down there for later. What a tragedy it is when something is ruined from water unexpectedly getting in to your basement and giving all of your belongings an unwanted bath. Waterproofing prevents this from happening and allows your basement to be a reliable, usable space!

Preserve Structural Integrity

Water on a foundation is very detrimental to the health of your home's stability. When moisture is constantly on the foundation, it can lead to cracks forming and the overall weakening of the concrete foundation as a whole. Basement waterproofing works to keep water away from your home's foundation, protecting the structural integrity for years to come.

Increase Home Value

The condition of the basement can be a huge reason to buy or avoid buying a home. A waterproofed basement has the potential to increase the value of your home. A house with a dry and functional basement is much more appealing to buyers than a wet, stinky, unusable one.
