Sealed Crawl Space Encapsulation in Raleigh

Benefits of a sealed crawl space from LiveGreen

Crawl spaces under homes aren’t usually at the top of the must-see features of a house. That’s because traditionally crawl spaces were considered dark, dank and dirty. Not anymore! At LiveGreen, we can install a sealed crawl space encapsulation system custom tailored to your home that makes the crawl space not only more pleasant, but a lot better for you and your family.

Think about it: Your entire home sits on top of your crawl space, and that space underneath you can vastly affect the air you’re breathing in the regular rooms, and also your home’s comfort. And that can vastly affect your home’s energy efficiency and utility bills.

One of the primary benefits of an encapsulated crawl space is moisture prevention and vapor barrier. When moisture collects in your crawl space, it can lead to big problems including mold and mildew, pest and rodent infestations, sagging insulation, and filthy ductwork that directly affects the quality of the air you and your family are breathing inside the home.

When you hire LiveGreen to seal your crawl space you get a wealth of benefits, not just to your health, but to the health of your home itself, due to improved structural integrity of the wood framing and flooring system.

Can sealing my crawl space lower my energy bill?

With crawl space insulation, the air you pay to heat or cool stays put- no longer leaking out from dozens of possible exit points. As a result, your HVAC system works more efficiently for improved comfort and savings. And because the crawl space barrier prevents moisture from leaking in, there’s less chance for mold or dry rot…and the pests that those typically attract, like termites, which can cause costly structural damage.

Bottom line- pardon the pun- because of all the ensuing benefits, encapsulating your crawl space immediately adds value to your home. Realtors and builders alike will tell you a sealed crawl space is an attractive feature when it comes time to sell or refinance your home.

Avoid Radon gas in your home

And then there’s the RADON issue. As you may know, Radon gas is emitted when rock or brick decomposes, and it’s a real risk in our area because it’s a form of radioactive decay usually found in gravelly, sandy-mixed soils like ours. Radon is unpredictable: Levels can vary drastically from house to house, and affects home no matter their age. Because it has no odor, Radon gas issues can go undetected even at high levels. But a sealed crawl space from LiveGreen can be a huge help for Radon mitigation. When we come out and encapsulate your crawl space, the plastic sealed liner can be installed with slotted pipes underneath to extract the gas, improving the health of your family and home. Why run the risk of Radon exposure, when simply sealing your crawl space can mitigate its danger?

Sealed Crawl Spaces FAQs

Excessive moisture under your house can lead to big problems, so installing a vapor barrier is a wise investment to protect your home and family. Basically, a vapor barrier stops moisture from the ground rising and getting into your home. In the crawl space area, that means the vapor barrier protects your structural surfaces (wood, walls, floors) from exposure to too much moisture. That’s important because too much moisture can lead to mold, wood rot, and flooring damage. A vapor barrier can also mitigate soil gases from leaking into your crawl space and home, like radon and methane. Because of how it protects your home, a vapor barrier can also improve interior air quality and make your home more energy efficient. Vapor barriers come in a range of thicknesses, and our Live Green team would be happy to show you which would work best for your home.

A very little bit of moisture under your house is normal. But some indications that there is too much moisture in your crawl space and could be affecting your home and family include:

  • Humidity indoors
  • Mold growth, in both interior spaces and under the house
  • Musty odor
  • Flooring may be buckling or cupping in spots
  • Falling or sagging insulation in your crawl space

In older homes, the practice was to vent the crawl space with vents that could be open or closed from the exterior of the home. The idea was that moisture and humidity would be released through the vents from under the house, dispelling the moisture. Traditionally vents also offered crawl space air movement. However as building practices and technology changed, so did the approach to preventing moisture damage in crawl spaces.

A key thing to realize is that in our region, during three seasons of the year we’re exposed to warm, humid air that can make its way from outside into your crawl space via crawl space vents. That air then actually makes conditions under your home worse, by contributing to the moisture issue: Once the warm air is trapped under your home, as it cools the humidity condenses, and can lead to moisture problems like mold and mildew, pest infestation and dirty ductwork.


At Live Green, we can install a sealed crawl space encapsulation system to prevent moisture, pests, environmental dangers, and protect your home from external humidity.. That can improve the structural integrity and health of your home, as well as the health of your family!

Absolutely! A sealed crawl space protects the structural integrity of your home, so is worth its weight in gold for not just protecting your home investment, but adding an attractive feature that can improve your home’s resale value.

Think about it from a home buyer's perspective: A sealed crawl space protects your home's structure and interior from moisture and Radon gas, and stabilizes the air under your home, cutting down on air seepage. That means your home is more energy efficient- an excellent selling point!

Why seal your crawl space?

Cost considerations for sealing a crawl space

  1. Size of your crawl space: The size of your home’s crawl space will help determine the overall cost of the project. Naturally, a larger crawl space requires more materials, time, and labor, which will increase the cost of the project.
  2. Access to the crawl space: Because most people will never see your crawl space, access to it can be tricky. And in some cases, accessibility to the crawl space can affect the cost of the project. If the crawl space is difficult to access, it may require more time and labor, which will increase the cost.
  3. Type of insulation: The type of insulation used will also affect the cost of the project. There are different types of insulation materials available, such as fiberglass, spray foam and cellulose. Each type of insulation has its own cost considerations.
  4. Ventilation requirements: Adding vents or sealing existing ones may have a bearing on the cost of your project.
  5. Additional repairs: When Live Green seals your crawl space, we may discover other issues that need to be repaired, such as water damage, mold or structural issues. We will address these issues with you up front, so you’re aware of any costs this adds to your project. The energy assessment will help us determine if any additional issues exist in your crawl space, so we can give you a dependable free quote at the start of the project.

Crawl Space issues in Raleigh NC

Welcome to Raleigh, where we can vacillate wildly between storms dropping buckets of water on the area, or having to set out the sprinkler because our lawn is parched and yellowing.

While regular moisture can be great for your lawn and landscaping, that same influx of intermittent bouts of heavy rain can wreak havoc in your crawl space. Because the Triangle is a temperate climate and we enjoy four distinct seasons, we don’t really have a `dry season’, and sometimes have to contend with snow or ice as well.

Smart homeowners know that crawl space encapsulation is a great idea for homes in the Raleigh area, and no one is better at it than LiveGreen Inc! You can see testimonials on our website from satisfied customers, and we’re proud of our reputation in Raleigh and the surrounding area of being the business to turn to if you need help taking care of your home.

‘Why should I seal my crawl space?’

Most homes in the Raleigh area are built on a foundation with space underneath the house. Moisture can seep into that crawl space through your foundation or from the ground beneath your home. If moisture collects there, mold and mildew usually aren’t far behind- they feed off excess moisture in an area. And that can lead to a host of problems, both for your structure, and the people living inside of it.

Some indications that too much moisture may be a problem in your crawl space are:

  • Indoor humidity- Is the air inside your house moist or sticky? Is your inside air affected by moisture fluctuations outside?
  • Musty odor- Do you notice a faint musty or moldy odor in areas of your home? Does your carpet smell musty?
  • Mold Growth- This is the easiest problem to spot in your crawl space, as mold blooms will show up on interior foundation walls and support beams under your house. Check your crawl space regularly for signs of mold or mildew.
  • Structural Issues- Are there `soft spots’ in your downstairs floor? Are your floorboards buckling in spots, or pulling away from baseboards?

One of the biggest benefits of hiring LiveGreen to encapsulate your crawl space is you get moisture prevention and vapor barrier. Collected moisture can not only cause mold and mildew problems, but can lead to pest and rodent infestations, sagging insulation, and filthy ductwork – which can cause problems in the air your family breathes in your home.
