The goal of crawl space repair is to eradicate excess moisture, enhance indoor air quality, and restore the stability of the home’s structure. Repairs also help to improve energy efficiency in the home. Here are a few steps to take as you or a professional implement repairs in your crawl space: 

Conduct a Thorough Inspection

Inspect the crawl space to identify problem areas. Issues of concern may include challenges with moisture levels, insulation, and structural issues. A hygrometer can help to monitor the humidity levels in the crawl space. Assess areas that point to a pest infestation, including termites, rats, and ants. You may also identify areas where there are uneven or sagging floors.

Implement Moisture Control

Managing the level of moisture is part of the crawl space repair process. To help prevent water from collecting around the foundation, try diverting it away from the structure. This can be done by regrading the landscape and installing French drains. A sump pump may also be useful, especially if water tends to accumulate in low areas; placing the pump at the lowest point allows it to effectively remove standing water. If there's no vapor barrier in place, adding one helps reduce moisture in the crawl space. This involves laying a thick plastic sheet over the ground. In cases where biological growth is present, applying a fungicidal treatment helps address the issue and prevent further growth.

You can also opt for encapsulation, which involves covering all surfaces in the crawl space with a heavy-duty polyethylene sheeting. This step locks out moisture, leading to improved indoor air quality. It also helps to prepare the space to integrate other updates, such as dehumidification or insulation.

Improve Insulation and Ventilation

If your insulation is old, torn, or wet, it may be ineffective. Replace the old insulation with newer materials that offer improved resistance to moisture. This crawl space repair step leads to improved air quality and efficiency because it helps to regulate indoor temperatures. You may also reapply sealant to maintain the improvements achieved from the repairs.

Proper ventilation is key for preventing moisture buildup and reducing stagnant air in the crawl space. If adequate ventilation is lacking or existing vents are damaged, it may be beneficial to consult a professional. They can assess the current setup, clean or repair existing vents, and recommend whether additional vents should be installed to improve air circulation and overall air quality.

Protect Against Pests

Pest and rodent intrusion often occurs through small cracks or gaps in the crawl space. A professional inspection can help identify potential entry points. Once identified, sealing these openings is an effective way to deter unwanted pests. For smaller gaps, materials like steel wool combined with caulk or spray foam can be used to block access. Larger openings may require more durable solutions, such as metal flashing or cement. Around utility penetrations, such as wires, pipes, or conduits, pest control professionals may use expanding foam or copper mesh to offer a secure seal.

Complete Structural Repairs

Water damage might weaken wooden structures such as beams and joints. Professionals will repair or replace the damaged wood and provide additional support where necessary. Depending on the level of the damage, they may need to install new joists or reinforce weakened beams. Professional technicians will strengthen and stabilize the foundation by installing new footings or underpinning. They can also replace any rotten subflooring where necessary.

Hire Professionals for Crawl Space Repair

Taking the proper steps to keep your basement dry and safe will enhance the longevity of your space. After repairing the spaces to prevent the entry of moisture, air, and pests, you can also have a professional install a dehumidifier. This appliance helps to maintain your crawl space at a particular humidity level. Work with professionals to identify and execute the repairs your home needs.
