Work with a Second Generation Family Owned Nashville, TN Crawlspace Company That’s Been Around Since 1975 and Will Continue To Be Around In The Future.

Greg Lewis, the owner and founder of Crawlspace Makeover, started his late father’s (Ken Lewis) janitorial business back in 1975 during high school. He worked for him during the summer seasons during college and then went on to work for him full time after graduating. After graduating college (UTC), Greg moved on to work a few years for the Boy Scouts of America.

Greg and his father bought the Sears Carpet Cleaning franchise servicing the Nashville, Tennessee, area in 1987 and successfully operated it until 1999, when they sold the company. It was while operating the carpet cleaning franchise, which utilized gasoline-powered sucker trucks, that they began to learn about and service the extraction of water from water-damaged homes and businesses. This led them to other related services in the industry, such as mold remediation, and then on into managing indoor air quality by adding an air duct cleaning division.

Since most air ducts in Nashville and surrounding areas are in the crawl space, which is usually a mess, a crawlspace renovation division was created.

  • Long-term Protection: While concrete provides a barrier, encapsulation offers an additional layer of protection against potential issues like mold, mildew, and structural damage.

While concrete crawl spaces are generally more resistant to moisture-related issues, encapsulation can offer added benefits. Homeowners should evaluate the specific conditions of their crawl space and consult professionals to make an informed decision.

Can I encapsulate a dirt crawl space?

Yes, encapsulating a dirt crawl space is not only possible but often recommended. Here’s why:
  • Moisture Control: Dirt crawl spaces are prone to moisture, leading to mold, rot, and structural issues. Encapsulation seals off the crawl space, preventing moisture intrusion.
  • Improved Air Quality: By encapsulating, you can prevent damp, moldy air and soil gases from rising into the living spaces, leading to healthier indoor air.
  • Energy Savings: An encapsulated crawl space can act as insulation, reducing energy costs by stabilizing indoor temperatures.
  • Pest Deterrence: By sealing the crawl space, you reduce the likelihood of pests such as rodents and insects making it their home.
  • Increased Home Value: A clean, encapsulated crawl space can be a selling point, indicating to potential buyers that the home is well-maintained and free from moisture-related issues.

If you have a dirt crawl space, it’s essential to consider encapsulation, especially if you’re facing moisture-related challenges. Always consult with a professional to ensure proper installation and to get the best results.

Are there any drawbacks to encapsulation?

While crawl space encapsulation provides numerous benefits, like moisture control and energy efficiency, there are potential drawbacks to consider:
  • Initial Costs: Encapsulation can be an investment, and the upfront costs might be high depending on the size of the space and materials used.
  • Improper Installation: If not done correctly, encapsulation can trap moisture inside, leading to the very problems it aims to prevent.
  • Maintenance: Over time, the vapor barrier might get damaged, requiring periodic inspections and potential repairs.
  • Not a Complete Solution: Encapsulation primarily addresses moisture but might not resolve other issues like radon gas or pests without additional measures.
  • Oversealing: Over-encapsulating without proper ventilation can lead to stagnant air and other problems.

Before deciding on encapsulation, homeowners should weigh the pros and cons, research contractors, and consider the specific needs of their property. It’s essential to ensure the job is done correctly to avoid potential pitfalls.

What happens if water gets into the encapsulated space, like from a plumbing leak?

If water enters an encapsulated crawl space, especially from a plumbing leak, it can present potential problems. Here’s what you need to know:
  • Pooling Water: Encapsulation seals off the crawl space. If a significant leak occurs, water can pool inside, potentially damaging the vapor barrier and the home’s structure.
  • Mold and Mildew: Standing water can create a humid environment, which might lead to mold and mildew growth, even in an encapsulated space.
  • Material Degradation: The moisture can weaken insulation materials, wooden structures, and other components within the crawl space.
  • Odor and Air Quality: Water damage can lead to musty odors that can permeate the living space, affecting indoor air quality.
  • Addressing the Issue: It’s crucial to detect and fix any leaks promptly. Installing a sump pump and dehumidifier in the encapsulated space can help remove excess water and control humidity.

Regular inspections of the encapsulated crawl space, especially after significant plumbing work or heavy rains, can help detect issues early on. If you suspect a leak, consult with professionals to assess the situation and determine the best course of action.
