The crawl space has an integral role towards a home’s overall value as well as the living space above. Most homeowners in Bluff View Chattanooga don’t think twice about their crawl space unless they have to make repairs to plumbing, heating ducts or house wiring. While often thought of as no more than a storage area, it also has a tremendous impact on the overall indoor air quality of the entire home.
The Best Basement Waterproofing In Bluff View TN
By default, the air quality of a crawl space is typically poor. Mold, mildew, radon gas and poor energy efficiency all create several problems. The air that circulates within it eventually makes its way up through the living space. Scientific studies show that up to 50% of living space air originates from the lowest level of the home. With homeowners more concerned about their home’s indoor air quality, the encapsulating of crawl spaces has become a popular solution for such problems.
A damp crawl space creates a safe harbor for harmful molds, in addition to dust mites, termites and other bugs that can infest the home. The presence of excessive moisture will also create a serious problem with the probability for the wooden structure of a home to deteriorate. Crawl space vents pose a further problem. While believed to be a solution to moisture problems, they, unfortunately, make the problem worse. As it turns out, the vents allow cold air and moisture in, which rises into the living area and therefore decreases the heating efficiency of the entire home.
Another all-too-common problem associated with crawl spaces is radon gas. Though it cannot be seen, smelled or tasted, radon is a radioactive gas that can contribute to poor health, including cancer. Radon gas makes its way through the earth, into the crawl space and the home’s living space. According to the U.S.E.P.A., radon gas is the number one leading cause of lung cancer in non-smokers.
Ignoring these various conditions is not recommended for both long-term health and energy usage. Fully encapsulating a crawl space – by both sealing and insulating – is a fully efficient measure in addressing such problems. It makes sense to maintain and improve the lower level area in order to maximize healthy living conditions and home resale value.
While there are several systems for encapsulating, a zero perm liner system that also insulates and reflects heat provides the most benefits. With a proper floor and wall liner, the area will not only be well insulated but will seal out moisture, bug infestation, and radon gas. Other components to look for in a system include a radon gas-dispersing drain fabric, a radon gas ventilation pipe, and a ceiling heat shield.
A complete system with all of the above components will allow any soil gasses – including radon gas – that naturally occur under the liner system, to wick through the drain fabric and escape out through the ventilation pipe. While improved indoor air quality is the primary benefit of a sealed and insulated crawl space, the homeowner will also appreciate a bright, clean, and dry storage area; the ridding of musty smells; less energy usage; and tax credits. Contractors encapsulating crawl spaces will have more to offer to their clients when they can assure the peace of mind with improved indoor air quality.
A Closed, Sealed Crawlspace - What a Really Bad Idea
Crawl Spaces have been always around, but they became increasingly popular when homeowners started to recognize the improved convenience they have. Compared to the conventional floor setups and concrete floors, crawlspaces granted easy access to the plumbing setup and air ducts, and repairing them became effortless. Moreover, crawlspaces were also used as a storage facility. However, like any good thing in the world, crawlspaces also have its fair share of problems: trapped moisture, vermin, termites, and carpenter ants; invasion of wildlife and accumulation of foul gases to name a few.
I've been doing crawl space encapsulation business for more than two decades now. A good number of correspondences I have addressed were always concerning the foul smell and bad odors that are generated from crawlspaces. It's imperative to recognize the root causes behind such foul odors and we need to work on strategies that will eliminate the root causes. Crawlspace encapsulation is relatively a new technique which will help you to protect your crawl space, and the health of your family. However, you need to know how to choose the right encapsulation system for your home.
By encapsulating your crawl space, you no longer have to worry about rodents or other wild animals invading your crawl space, moisture accumulation, termites and foul smell that was haunting you for long. A Do-It-Yourself encapsulation kit will undisputedly help you to protect your home from unwanted disasters.
Choosing the Right Crawl Space Encapsulation System: Things to Look For:
There are four potential threats for your crawl space: mold, water, rodents and other animals. Foul smell is a result of all these elements. Your crawl space is the natural source of fresh air but when odor is generated in this area, the fresh air entering your home will also be affected. By eliminating the root causes of odor, you can significantly improve the air quality in your home.
- Liner: I receive several phone calls from disappointed customers who spent their hard-earned money on thin liners because some store owner advised them to do so. However, any liner material without 0.000 permeability and at least 20mil thickness won't help you to encapsulate the system and prevent water and radon gas entering your home.
- Water: You need a waterproof encapsulation because this will help you to prevent rain water or any other source of running water entering your crawlspace. Moreover, this will also help you to bring down the moisture level, which is a good initiative in making your crawl space unsuitable for rodents and mold.
- Dehumidifier: If you install the proper liner system, the need for a dehumidifier is greatly reduced as the purpose of removing moisture. The reason being, that a proper liner system will stop the water or moisture before it gets into the home or crawlspace, thus eliminating the need for a dehumidifier.
- Mold Neutralizer: Dehumidifiers can prevent mold growth to a large extent, but mold neutralizer destroys bacteria, algae and mold and also prevents their future growth.
These are some important factors to be considered when installing an encapsulation system for your home. You also need to consider the warranty & price offered by your store owner. Maintaining your home can be expensive, but by investing in professional encapsulating systems that will protect your home for several decades, you're making a wise investment.
Crawlspace Vapor Barrier Installation
A crawl space dig out is the process of turning your crawl space into a basement. This vastly increases storage space and can, in some cases, increase living space as well.
But, a crawl space dig out can be an enormous and daunting task. And, if done improperly, it can be dangerous. If you don't want to have a professional do it for you, please follow the steps below.
To get started, find place in the outside wall of your crawl space that you can safely enter the new basement with a temporary or permanent set of steps. Make sure the wall opening is big enough to handle at least a 36-inch door, preferably making the area for the steps at least 48-inches wide.
If your soil is sandy or gravel and or may be full of water at least part of the year do not consider this procedure, it is very dangerous and you may damage or lose your house.
Make sure that prior to digging the hole for the outside exit, please build a header of sufficient size to hold the floor of the home where you will be removing the old foundation.
You need to excavate to a depth that will accommodate a four-inch concrete slab and still have at least 7-foot, 6-inches of clearance under your floor joist. It is entirely possible that you will have 48 inches of soil to remove.
When digging out a crawl space, you can not excavate any closer than 24 inches away from the existing foundation.
You can remove the soil sufficiently to work along the wall without removing the entire area you wish to change.
When you get the soil out to a depth that you prefer, pour a footer that is eight inches thick and 16 inches wide. The footer should be below the bottom of the new slab so it is a good idea to dig the area for the footer below the level you remove for the floor area. This is a very important step in a crawl space dig out.
Then, when your block is level with bottom of the old foundation wall you need to pour a four-inch thick slab of concrete on top of the wall and over to the outside existing wall.
Prior to pouring your "Cap" you must fill between the block and soil that is under the old foundation with fill sand or "Pea-gravel." Assuming that you probably have some kind of support under the center section of the floor system, you will have to provide support for the beam that is presently supporting the floor while excavate for a new footer for a steel post that will hold the floor of your new space.
Make sure your footer for this part of the project is about eight inches thick & 24 inches square.
You will need to level the floor area for your new slab and install four inches of perforated plastic pipe draining to a sub pit with an automatic sub pump that dispenses the water to the outside at least five to ten feet away from the foundation of the home. I'd suggest using "Pea-gravel" for fill under the slab but you can you fill sand also.
Now, build your stairs to the outside in a similar fashion but you need to cover it with a steel "pre-fab" unit such as a "BILCO."
If you do this correctly and maintain it, it will last for many, many years. It is strongly suggested you get a professional to do this job or at least help with it because mistakes can be dangerous and very costly.
