6 DIY Crawl Space Repair Jobs Gone Wrong 

The crawl space is an often overlooked part of the home. Because of this, many homeowners turn to DIY repairs to save money instead of seeking professional help. However, easy fixes can increase the risk of injuries, the cost of repairs in the long run, and leave the problem worse than it was before.  

On this page we’ll explore a few of the common do-it-yourself mistakes we see homeowners make in their crawl space and why it’s essential to hire crawl space repair professionals. 

6 DIY Crawl Space Repair Jobs Gone Wrong 

Here are six examples of mistakes that can be made with DIY crawl space repairs: 

Inadequate Moisture Barrier 

Installing a moisture barrier in a crawl space is crucial for preventing moisture issues. However, if the barrier is not properly installed or if there are gaps or tears in the material, moisture can still seep through, leading to mold growth, wood rot, and other moisture damage. 

Poor Ventilation 

Improper ventilation can exacerbate moisture problems in crawl spaces. DIY attempts to add vents or fans without understanding airflow dynamics can result in inadequate ventilation, trapping moisture inside and leading to issues like mold and mildew. 

Improper Insulation Installation 

Incorrectly installing insulation or adding fiberglass to a wet crawl space can result in thermal bridging, where there are gaps or voids in the insulation. This can lead to energy inefficiency and temperature fluctuations within the home. 

Improperly Installed or Sized Drainage Systems 

DIY drainage systems such as French drains or sump pumps may be improperly installed or sized, leading to ineffective water removal. This can result in water pooling in the crawl space, causing structural damage and creating a breeding ground for mold and pests.  

Neglecting Pest Entry Points  

Attempting to control pests in the crawl space without addressing all entry points can lead to ongoing infestations. Simply laying down traps or spraying insecticides may not be enough to prevent pests from returning or finding new entryways. 

Substandard Structural Repairs 

DIY attempts to repair structural issues in the crawl space, such as sagging floors or damaged support beams, can lead to further damage if not done correctly. Improperly installed supports or inadequate reinforcement can compromise the stability of the home. 

Crawl space repairs can easily go wrong without the proper tools and expertise. That’s why we recommend soliciting professional contractors to ensure safety, quality, and long-term effectiveness. 

How Tar Heel Approaches Crawl Space Repair 

Tar Heel Basement Systems follows a systematic approach to ensure effective and long-lasting solutions. Here’s how we generally approach repairing a crawl space: 

  • Initial Inspection: Our trained technician conducts a thorough inspection of the crawl space, assessing various factors such as moisture levels, structural integrity, insulation, ventilation, and potential pest issues. They identify any existing problems and determine the root causes contributing to issues such as moisture accumulation, mold growth, wood rot, or pest infestations. 
  • Customized Solution Design: Based on the inspection findings, our technician develops a customized repair plan tailored to address the specific needs and challenges of the crawl space. The repair plan may include a combination of moisture control measures, structural repairs, insulation upgrades, ventilation improvements, and pest management strategies. 
  • Moisture Control: Addressing moisture issues is typically a priority in crawl space repairs. This may involve installing a vapor barrier to prevent moisture from seeping into the crawl space from the ground. Additionally, a drainage system such as a French drain or sump pump may be installed to effectively remove excess water from the crawl space. 
  • Structural Repairs: If the crawl space has structural issues such as sagging floors or deteriorating support beams, these are addressed using appropriate structural repair techniques. This may involve reinforcing damaged support beams, installing additional supports or piers, and ensuring proper foundation support. 
  • Insulation Upgrades: Insulating the crawl space is essential for maintaining consistent temperatures inside the home and preventing energy loss. Proper insulation installation also helps to minimize moisture issues and reduces the risk of mold growth. 
  • Ventilation Improvements: Improving ventilation helps to promote airflow within the crawl space, reducing humidity levels and preventing stagnation. This may involve installing or replacing crawl space doors and entry points for optimal airflow and ensuring proper air circulation throughout the crawl space. 
  • Pest Management: Addressing pest infestations in the crawl space is crucial for protecting the home’s structure and indoor air quality. Pest control measures may include sealing entry points, installing pest barriers, and treating affected areas for pests such as termites or rodents. 

At Tar Heel, we are committed to comprehensively addressing crawl space issues and providing homeowners with a healthier, more stable, and energy-efficient living environment.
