Remove Standing Water in Crawl Space

You might think that basements in America are the most common form of foundation. That is a fair inference, but it is inaccurate. Fifty-four percent of homes are constructed on concrete slabs. Only 30% have a full or partial basement of the three primary residential home foundation forms (full or partial basement, crawl space, and concrete slabs).

So, what are the foundations of the remaining 16 percent of houses? Crawl spaces are found in 15% (roughly 27 million) of these homes, while the remaining 1% are constructed on rooftops or breakwaters. Basements are well-known, and a concrete slab is precisely that: a slab of concrete. “What is a crawl space?” is a question that many homebuyers have. The short answer is that a crawl space is a basement that provides a barrier between the ground and the first floor of your home, which is why basement waterproofing, and or crawlspace waterproofing is a needful thing.

What effect does standing water in a crawl space have on a home’s value?

In and of itself, standing water in the crawl space does not affect a home’s worth. Mold is a factor that affects a home’s value when there is stagnant water in the crawl room. Mold can have a significant impact on a home’s appraised value. For example, FHA appraisers must note whether mold is growing in a home and the type of mold, and its position. If you discover black mold growing in your house, there are a few things you should know: Toxic black mold can harm your health for the rest of your life, and in some cases, it can even kill you.

What is the best way to get rid of water in the crawl space?

Crawl space moisture control problems are exacerbated by improper grading and the lack of rain gutters, which enable excess rain or ground water to enter the crawl space. Poor crawl space ventilation exacerbates the issue by mixing warm and cold air, causing surface condensation and raising moisture in the crawl space underneath the building. This regular wetting of building materials creates the ideal environment for mold to flourish, termites to thrive, and structural damage to occur underneath your house. Contact us for the best crawl space water removal services in Carolina. When dealing with water in the crawl room, standard solutions include:

  • Moisture is directed away from the structure by proper grading around the building.
  • Gutter and downspout installation, repair, and cleaning
  • To transfer water away from the building, add downspout extensions and exit lines
  • Waterproofing may be done on the inside or outside of a building
  • Isolating the crawl space from the ground with vapor barriers or encapsulation devices.
  • Crawl space ventilation, such as crawl space dehumidifiers and/or crawl space ventilation fans, should be installed.

Crawl Space Ventilation vs. Crawl Space Conditioning

Crawl spaces with ventilation: Several air vents are situated at the top of the foundation wall in ventilated crawl spaces. Outside air flows freely across the room since the vents are positioned across from one another. Nonetheless, since the airflow is unregulated and unconditioned, the air (whether hot or cold) can be full of moisture, vents have been shown to do more harm than good. It is possible, but not fast, to insulate a vented crawl room. Insulation is usually mounted between floor joists, but it can be difficult to install insulation around plumbing, wiring, and other obstructions. This form of installation, as tricky as it may be, is used in some new homes.

Crawl spaces that have been conditioned: Crawl spaces with air conditioning have insulated walls and a vapor barrier installation on the floor that is connected to the HVAC system. There are no more vents to the outside, and there is no need for insulation between the floor joists in this form of crawl room. A vapor barrier covering the soil in a crawl space is needed to reduce moisture from the ground. Crawl spaces with no vapor barrier can absorb even more moisture. The vapor barrier also maintains a consistent temperature throughout the year, allowing the heating and cooling system to operate efficiently.

Vapor barriers

A vapor barrier is necessary for crawl spaces, but what exactly is it? Randy Reeds, a top-rated real estate agent in Kent County, Michigan, explains: “I deal with 72 percent or more single-family homes than the average agent in my field. In a crawl space that isn’t concrete, there are fabrics that contractors can lay down to serve as a vapor barrier. They’ll lay thick plastic under the entire house today to seal it, similar to rubberized roofing material.”

To eliminate any extra moisture in a crawl space with a dirt floor, use cross-ventilation, a dehumidifier, or an exhaust fan. Keep in mind that a dehumidifier’s moisture removal capacity is determined by how many quarts of water it can extract every hour. Also, since ambient air contains moisture, it’s essential to keep air flowing to and from the dehumidifier. To maximize airflow, you’ll probably want to add multiple fans in the crawl room. The crawl space may become flooded during a heavy rainstorm, necessitating a professional’s use to drain out the water and the installation of a sump pump.

Benefits of a crawl space

Crawl space encapsulation is one of the most popular ways to seal the crawl space. This process entails covering the floor and walls with thick white plastic sheets. To keep the crawl space dry and mold-free, you’ll need to invest in a sump pump and a dehumidifier. It all comes down to having a dry crawl room, which has a lot of advantages! Let’s take a closer look.

Access

The most significant advantage of a crawl space over a concrete slab base is that the systems, as mentioned earlier, such as wiring, plumbing, gas hookups, and ventilation, are all readily accessible. If you have an issue with these aspects of your home, you or a contractor can make the required repairs by crawling into the crawl space underneath the building.

Cost

Basements (finished or unfinished) provide links to the structures mentioned above. They have more livable space (which 44 percent of real estate agents claim their clients want), while a crawl space doesn’t. The trade-off is that a crawl space can save you a lot of money when you’re building a house — and most basements aren’t included in a home’s square footage anyway. A crawl space foundation will cost between $8,000 and $21,000 on average, while a basement will cost between $18,000 and $30,000, based on total square footage.

Versatility

When a traditional basement isn’t an option, such as on a waterfront property or where the ground is sloped, crawl space foundations are used. In places where the ground is vulnerable to excessive dampness or termites, crawl spaces are also the basis of choice.

The drawbacks to having a crawl space

Crawl spaces are used to house plumbing, electrical wiring, ductwork, air conditioning, and heating systems, as well as to provide unlimited access to these substructures. A crawl space’s problem is that it can rapidly become filthy and damp. Mold, fungus, termites, and rats may all be a problem in the crawl space if there is too much moisture.

  • Moisture: Moisture isn’t a crawl space’s best friend, mainly if it’s an older home with a ventilated crawl space. Excessive moisture may cause rot by compromising the structural integrity of wooden pieces. Replacement of rotted support beams can cost anything from $1,500 to $5,000, depending on the material used (wood or steel) and how easy the issue is to fix.
  • Mold, mildew, and fungus: “If there is some water problem, the combination of that and inadequate ventilation leads to mold and mildew, which eventually rots the floor joists. If this is the case, mold removal is a must. And there’s the health problem of walking on a floor that has a lot of mold beneath it.” Reeds elucidates. When a moisture issue isn’t tackled, the crawl space becomes an ideal breeding ground for microorganisms like mold and mildew. The harmful microorganisms and bacteria will spread throughout the house if the air from the crawl space circulates. For residents with respiratory problems or allergies, this could spell disaster!
  • Pest infestations: Crawl spaces that aren’t properly sealed are vulnerable to insect infestation. The warmth and moisture found there attract rodents and small animals. Because of their dander and hair, insect infestations can pollute the air, but their droppings are also a health hazard. Insects such as termites, in addition to small animals, can cause damage to structural components, HVAC ducts, and wiring.
  • Poor insulation: Heating and cooling systems can be hindered by crawl spaces that have not been adequately enclosed or insulated. The furnace or heater may have to work longer to maintain temperature if the outside air is colder or hotter

Is it a good idea to buy a home with a crawl space?

You’ve noticed a house that you’d like to buy, but it has a crawl space. Should you make an offer right now? You can do so as long as a specialist has inspected the crawl space and determined that there is no mold, no standing water in your crawl space, and that the walls and footings are in good shape.

Along with adequate crawl space ventilation, make sure there are no holes in the ground that could cause rodents or small animals to enter the room. Insect screens should be installed on any vents to keep bees, hornets, and other insects out of the building. Remember that having a crawl space makes it much easier to reach the home’s numerous structures if something goes wrong. You must ensure that there is enough ventilation to avoid excessive humidity, which can be harmful to the structure of the house and the inhabitants.
